Physical Access Control Systems: 7 Powerful Must-Know Facts 2025
Securing Your Space: Who Can Enter, When, and How
Physical access control systems are electronic security solutions that regulate who can enter specific areas of a building or facility. They combine hardware and software to authenticate users and manage access permissions.
What is a Physical Access Control System (PACS)?
– Definition: An electronic security system that controls entry to buildings or rooms
– Purpose: Prevents unauthorized access while allowing legitimate entry
– Components: Readers, credentials, controllers, locks, and management software
– Common methods: Key cards, PINs, biometrics, and mobile credentials
– Benefits: Improved security, audit trails, deterrence, and compliance
In today’s security landscape, physical access control has become essential for businesses of all sizes. With property crime accounting for an estimated $15.8 billion in losses annually in the United States, and insider threat incidents rising by 44% over the past two years, controlling who enters your premises has never been more critical.
Most modern physical access control systems replace traditional lock-and-key methods with electronic credentials that can be easily issued, tracked, and revoked. This provides greater flexibility and security, as lost or stolen credentials can be immediately deactivated rather than requiring expensive re-keying.
The core function of these systems is simple: authenticate users (verify who they are), authorize access (determine if they should be allowed entry), and maintain an audit trail of all access events (document who went where and when).

What Are Physical Access Control Systems?
Think of a physical access control system as your building’s electronic bouncer. Instead of relying on a security guard who might recognize faces (or might not, depending on their day), modern security needs something more reliable and trackable.
According to the experts at the National Institute of Standards and Technology (NIST), these systems manage “the ability of people or vehicles to enter a protected area, by combining authentication and authorization at access control points.”
In simple terms, a physical access control system decides who gets in, when they can enter, and keeps a record of it all. It’s like having a perfect memory of everyone who’s walked through your doors.
When we talk about access control, it’s worth understanding the difference between physical and logical systems. While physical access control systems guard real-world spaces like your office or warehouse, logical access control protects digital assets like your network and files. Many smart businesses now use both together for complete protection.
One of the most valuable features of these systems isn’t just keeping the bad guys out – it’s creating a detailed paper trail. Every tap of a card or scan of a fingerprint gets logged with exactly who tried to enter, when they tried, where they were, and whether they succeeded. This creates accountability and gives you crucial information if something goes wrong.

How do physical access control systems work?
The magic behind a physical access control system happens in six straightforward steps:
-
Credential Presentation: Someone walks up to a door and presents their credential – maybe swiping a card, tapping their phone, or placing their finger on a scanner.
-
Data Transmission: The reader captures this information and sends it to the control panel – the system’s brain.
-
Verification: The system quickly checks: “Is this person in our database? Are they allowed in this door at this time?”
-
Decision: Based on the rules you’ve set up, the system makes a call. Maybe executives can enter anytime, but contractors only during business hours.
-
Action: If everything checks out, you’ll hear that satisfying click as the door open ups. If not, the door stays firmly shut.
-
Logging: Either way, the system records everything – creating a digital breadcrumb trail of who went where and when.
Here’s an eye-opening fact: most intruders give up after trying to break in for just 60 seconds. This highlights why good physical barriers are just as important as the electronic brains behind your access control system. Even a one-minute delay can send potential troublemakers looking for easier targets.
Main components of a PACS
A complete physical access control system is like a well-rehearsed orchestra, with several key instruments playing together:
The physical barriers – your doors, gates, turnstiles, or mantraps – form the first line of defense by physically blocking unauthorized entry.
Your credentials are what users carry to prove their identity – traditional access cards, key fobs, mobile phones, or even their own fingerprints or face.
Readers are the devices that interpret these credentials, from simple card readers to sophisticated biometric scanners that recognize unique physical traits.
The controllers serve as the system’s decision-makers, processing information from readers and determining whether to grant access based on your rules.
Your management software gives you a user-friendly dashboard to add or remove users, set access levels, monitor events, and pull reports when needed.
Locking mechanisms – like electromagnetic locks or electric strikes – physically secure your doors and respond to the controller’s commands.
Finally, reliable power supplies (including backups) ensure your system keeps working even during outages – because security never takes a day off.
Difference between physical and logical access control
While both types of access control protect your assets, they focus on different territories:
Physical Access Control is all about the real world – controlling who can enter your building, specific rooms, or parking areas. It uses tangible things like access cards or biometric traits (think fingerprints) and protects tangible assets through physical hardware like doors and locks.
Logical Access Control, meanwhile, focuses on the digital field – managing who can access your network, applications, and data. It typically uses passwords, digital certificates, or multi-factor authentication to protect your information and digital assets through software and network infrastructure.
The smartest security approach today brings these two worlds together. Imagine using the same smart card to both open up your office door and log into your computer network. This creates a seamless experience for users while enhancing security through multiple layers of protection. It’s convenience and security working hand-in-hand – the best of both worlds.
Core Components & Technologies
Ever wonder what makes a physical access control system tick? Let’s take a peek under the hood at the essential components that keep your building secure.
Think of a PACS as an orchestra where every instrument must play in perfect harmony. The physical barriers serve as the percussion, setting the foundational beat of security. The credentials and readers form the string section, creating the melody of authentication. The controllers act as the conductor, making split-second decisions about who enters and who doesn’t. And finally, the management software ties everything together like a musical score.
Today’s systems have come a long way from simple lock-and-key setups. Modern physical access control systems now incorporate sophisticated encryption, lifelike biometric verification, and convenient mobile credentials that transform your smartphone into your key. Let’s explore each component in detail.
Barriers, Locks & Gate Hardware
The physical barriers in your access control system are your first and most visible line of defense. These aren’t just obstacles—they’re strategic deterrents designed to keep unauthorized people out while letting the right ones in smoothly.
Doors equipped with electronic locks form the backbone of most systems. These can range from standard office doors to heavy-duty security entrances. For higher security areas, you might opt for turnstiles that prevent the common problem of “tailgating” (when someone slips in behind an authorized person). In ultra-secure environments, mantraps create a double-barrier system where the second door won’t open until the first has closed, ensuring only authorized individuals pass through.
The heart of these barriers is the locking mechanism itself. Electromagnetic locks (or maglocks) are particularly popular, using an electromagnet that can hold doors shut with several hundred pounds of force. What’s neat about these locks is their flexibility—they can be configured as “fail-safe” (automatically open uping during power outages to allow emergency exit) or “fail-secure” (staying locked during outages for maximum security).

Credentials & Authentication Methods
How do we prove we’re really us? That’s the question authentication answers, and modern physical access control systems offer several compelling solutions.
The classic key card or fob remains incredibly popular—about 60% of businesses still use these trusty credentials. They come in various technologies, from simple proximity cards that just need to be held near a reader to smart cards with embedded microprocessors that store encrypted data.
Mobile credentials are rapidly gaining ground, with about 32% of businesses now using them. Your smartphone becomes your key through technologies like Bluetooth Low Energy (for convenient longer-range access), Near Field Communication (for tap-to-enter simplicity), or even on-screen QR codes.
For additional security, many systems incorporate PIN codes entered on keypads, often paired with cards or mobile credentials for that extra layer of verification.
Biometrics have moved from science fiction to everyday reality, with 30% of businesses now using some form of biometric identification. Your fingerprint, face, iris pattern, hand geometry, or even voice can serve as your credential—something you literally cannot leave at home!
For vehicle access, License Plate Recognition (LPR) systems are increasingly common, with cameras and software that automatically identify vehicles as they approach, perfect for parking garages and gated communities.
Scientific research on biometrics
Controllers, Panels & Power
If credentials are the keys to your kingdom, controllers are the wise gatekeepers making decisions about who enters. These electronic brains receive data from readers, process it according to your programmed rules, and send commands to your locking mechanisms.
Today’s control panels come in several flavors. Traditional panels are centralized controllers typically mounted in secure equipment rooms, connecting to multiple readers and doors. Edge controllers take a more distributed approach, with intelligence built right into the readers themselves, reducing wiring needs. IP-based controllers communicate over standard network protocols, making them flexible and easier to integrate with other systems.
Power planning is critical—after all, a security system that fails during a power outage isn’t much of a security system! That’s why robust physical access control systems include backup power solutions like uninterruptible power supplies (UPS) or dedicated batteries. For network-connected components, Power over Ethernet (PoE) offers an neat solution, delivering both power and data over a single cable.
At Security Camera King, we design our control panels with redundancy in mind. We believe your security shouldn’t take a coffee break just because the power does!

Connectivity & Cloud Management
The days of isolated security systems are fading fast. Today’s physical access control systems are connected, intelligent, and often cloud-enabled.
You have two main approaches to choose from: traditional on-premises systems or modern cloud-based solutions. On-premises systems keep everything local—software, databases, and processing all happen within your organization’s infrastructure. This gives you direct control but requires dedicated IT resources for maintenance.
Cloud-based systems, on the other hand, host the management software in the cloud while still allowing local access decisions if connectivity is lost. This approach lets you manage your system from anywhere with internet access—add users, modify permissions, or even lock down your entire facility while sitting on a beach (though we hope you never need to!).
The real magic happens when your PACS connects with other building systems. Through API integrations, your access control can work hand-in-hand with your video surveillance for visual verification, your visitor management system for temporary access, your HR database for automatic user updates, and even your building automation system for coordinated responses to events.
Of course, connecting your security system to networks brings cybersecurity considerations. Modern systems employ robust encryption, secure authentication protocols, and regular security updates to ensure your physical security doesn’t create digital vulnerabilities.
With the right components working together, your physical access control system becomes greater than the sum of its parts—a comprehensive security solution that’s both powerful and user-friendly.
Types of Physical Access Control Systems
Physical access control systems come in many flavors – each designed to match specific security needs, budgets, and operational requirements. At Security Camera King, we’ve helped businesses of all sizes find the perfect fit for their unique circumstances.
Think of access control like choosing the right lock for your home – what works for a storage closet might not be appropriate for your front door. The same principle applies when securing different areas of your business.
Card & Fob Systems
Card-based systems remain incredibly popular for good reason – they strike that sweet spot between security, user-friendliness, and affordability. These plastic credentials come in various technologies:
Proximity cards operate at 125 kHz and work with a simple wave near the reader. They’re convenient but keep in mind they offer more basic security since they can be duplicated with specialized equipment.
Smart cards kick things up a notch, operating at 13.56 MHz with embedded microprocessors that store encrypted information. Many businesses love these because they can serve multiple purposes – from building access to cafeteria payments and computer logins.
Key fobs function just like cards but in a compact package that attaches to keychains, making them harder to misplace than a card.
One huge advantage over traditional keys? When an employee loses their card, you simply deactivate it in the system and issue a new one – no expensive re-keying required!
Biometric PACS
Biometric systems use what makes us uniquely us – our physical characteristics – to grant access. You can’t forget your fingerprint at home, and it’s extremely difficult for someone else to use it.
Fingerprint recognition systems have become quite affordable and work well in most environments, though dirty work conditions can occasionally cause reading issues.
Facial recognition technology has made incredible strides with AI improvements. Today’s systems can easily tell the difference between a real person and someone holding up a photograph.
Iris scanning offers exceptional accuracy in high-security applications, though it typically comes with a higher price tag.
Hand geometry readers measure the unique shape and dimensions of a person’s hand – particularly useful in environments where fingerprints might be damaged or dirty.
Modern biometric systems address privacy concerns by storing mathematical templates rather than actual images of your biometric traits, and include “liveness detection” to prevent spoofing attempts.
Mobile Credential PACS
Why carry another card when most of us already have smartphones? Mobile credentials turn phones into access keys through dedicated apps, offering best convenience and flexibility.
Bluetooth Low Energy (BLE) enables hands-free access from up to 30 feet away – perfect for driving into parking garages without rolling down your window.
Near Field Communication (NFC) works similarly to tap-to-pay functionality, requiring you to hold your phone close to the reader.
QR codes displayed on your phone screen can be scanned by specialized readers to verify and grant access.
One of my favorite features of mobile systems is remote credential management. Imagine a contractor arriving at your facility – you can instantly grant temporary access to their phone without ever printing a badge, and automatically revoke it when their work is complete.
Keypad & PIN PACS
Sometimes the simplest solution is the most practical. Keypad systems require users to enter a PIN code, making them our most affordable option since there are no physical credentials to purchase or manage.
Simple deployment means you can get up and running quickly without complex infrastructure.
Group access is straightforward – just share the code with authorized personnel (though this does reduce individual accountability).
Code rotation – changing PINs regularly – improves security but requires communicating new codes to all users.
Many of our clients use keypads as part of a multi-factor approach – requiring both something you have (card) and something you know (PIN) for highly sensitive areas.
License Plate Recognition Systems
For vehicle access control, License Plate Recognition (LPR) systems are remarkably efficient. Specialized cameras capture license plates while software algorithms identify authorized vehicles, automatically raising gates or barriers.
These systems shine in parking management for corporate campuses, residential communities, and commercial garages. They’re also excellent for vehicle tracking and visitor management when you need to pre-register expected guests.
Modern LPR technology works in rain, snow, and darkness with accuracy rates exceeding 95% in good conditions. No more lost access cards or rolling down windows in bad weather!
Multi-Technology & Hybrid Systems
Most of our clients ultimately choose hybrid approaches that layer different technologies throughout their facilities. This creates a security ecosystem where the authentication method matches the protection level needed for each specific area.
For example, a manufacturing facility might use mobile credentials for general building access, biometrics for R&D labs, keypads for supply rooms, and LPR for the shipping yard.
This thoughtful, layered approach delivers the right balance of security and convenience throughout your facility while optimizing your investment. At Security Camera King, we’ll help you design a system that addresses your unique security challenges while respecting your budget constraints.
Deployment Models: On-Premises vs Cloud PACS
When setting up a physical access control system, you’ll face an important choice that impacts everything from daily management to long-term costs: should you go with an on-premises system or a cloud-based solution? This isn’t just a technical decision—it affects your budget, staffing needs, and how your security team operates day-to-day.
Think of it like choosing between owning a car outright (on-premises) versus using a ride-sharing service (cloud-based). Each has clear benefits depending on your specific situation.
On-Premises Physical Access Control Systems
On-premises systems are like having your security command center right in your building. All the software, databases, and processing happens on servers you own and maintain within your walls.
Many of our clients at Security Camera King prefer this traditional approach because it gives them complete control over their security infrastructure. Your IT team can directly access all components, and the system works even during internet outages—a critical feature for facilities where security can never be compromised.
The financial structure is typically a larger upfront investment followed by lower ongoing costs. You’re essentially buying the system outright with a one-time licensing fee, rather than “renting” it through monthly subscriptions.
For organizations with strict regulatory requirements, on-premises solutions offer another significant advantage: data sovereignty. All your access records and user data stay within your physical control, which can simplify compliance with certain regulations.
The trade-off? You’ll need dedicated IT resources to keep things running smoothly. Your team will handle server maintenance, perform software updates, and manage system backups. There’s also the matter of physical space and infrastructure—you’ll need secure server rooms and networking equipment, which adds to the total cost of ownership.
When your company grows, scaling an on-premises system can be challenging. Adding new locations or significantly increasing your user base might require hardware upgrades and additional IT support.
Cloud-Based Physical Access Control Systems
Cloud-based access control—sometimes called Access Control as a Service (ACaaS)—takes a different approach. The core management software and databases live in secure cloud environments, while the door controllers can still function locally if internet connectivity drops.
The beauty of cloud systems is their flexibility and accessibility. Your security team can manage everything—from adding new users to locking down facilities during an emergency—from anywhere with internet access. Whether you’re at home, on vacation, or at another office location, you maintain complete control through a secure web interface.
Software updates happen automatically in the background, ensuring you always have the latest features and security patches without any effort from your team. This significantly reduces the IT burden compared to on-premises solutions—no servers to maintain, no manual updates to apply, no backup systems to manage.
The subscription-based model means lower upfront costs, with expenses spread out as monthly or annual fees. This predictable pricing helps with budgeting and moves the expense from capital to operational, which many finance departments prefer.
For businesses managing multiple locations, cloud systems truly shine. Adding new sites or expanding to additional doors becomes remarkably straightforward, with minimal additional infrastructure needed at each location.
We’ve seen many of our multi-site customers switch to cloud solutions and immediately appreciate the simplified management. As one retail chain manager told us, “I can now see the status of every store’s access points from my phone—it’s like having eyes everywhere without having to be everywhere.”
The considerations? You’ll have ongoing subscription costs for as long as you use the system, and while local access decisions can still be made during internet outages, the management capabilities require connectivity. Some organizations also need to verify where their data is stored for compliance purposes, though most reputable providers address this concern.
At Security Camera King, we’ve designed both deployment options to meet the specific needs of different organizations. Our cloud solutions deliver enterprise-grade security with minimal IT overhead, while our on-premises options provide maximum control for organizations with specific compliance or infrastructure requirements.

Best Practices & Integrations
Implementing a physical access control system is just the beginning of your security journey. To truly maximize both security and operational benefits, you’ll want to follow industry best practices and consider how your PACS can work alongside other security systems you already have in place.
The most successful PACS implementations start with clear policy development. Take the time to create comprehensive access control policies that spell out exactly who can access which areas, during what times, and under what circumstances. This foundation makes everything else run more smoothly.
I’ve found that implementing role-based access control makes life so much easier for everyone involved. Instead of assigning permissions to individuals (which becomes a nightmare to manage), you assign them to job functions. When people join your organization, change roles, or leave, managing their access becomes simple and systematic.
Don’t set it and forget it! Regular audits are essential for maintaining security integrity. Schedule time to review access logs, check user permissions, and verify system configurations. These routine check-ups help you spot and address potential security gaps before they become problems.
Even the best systems can experience issues, which is why incident response planning is so important. Develop clear procedures for how your team should respond to security breaches, unauthorized access attempts, or system failures. Then practice these procedures regularly – when an actual incident occurs, you’ll be glad you did.
Your physical access control system is only as good as the people using it. Invest time in user training to ensure everyone understands how to properly use the system, why they should never share credentials, and the proper procedures for reporting lost or stolen credentials.
Integrating PACS with Video & Alarms
One of the smartest moves you can make with your physical access control system is integrating it with video surveillance and alarm systems. This creates a comprehensive security ecosystem where your systems talk to each other, share information, and respond to events together.
When it comes to video integration, the benefits are immediate and powerful. With integrated systems, you gain visual verification capabilities – when someone presents a credential, the system can display their stored photo alongside a live camera feed for comparison. This makes it easy for security personnel to confirm identities at a glance.
Your integrated system can also provide event documentation by automatically bookmarking access events in your video management system. This makes it incredibly easy to find relevant footage later if needed. The system gains contextual awareness too – unusual access patterns can trigger recording or alert security personnel to review the video.
For forensic investigation purposes, this integration is invaluable. If a security incident occurs, your team can easily correlate access records with video evidence, giving you a complete picture of what happened, when, and who was involved.
Alarm integration brings its own set of benefits. You’ll have coordinated response capabilities where access events can trigger appropriate alarm responses based on rules you define. During emergencies, your emergency procedures can be automated – the system can lock or open up specific doors as needed.
We’ve also seen how valuable duress capabilities can be for our clients. Special codes or procedures can silently alert security to situations where someone is being forced to grant access against their will. And with unified monitoring, your security team can watch and respond to both access control and alarm events from a single interface.
At Security Camera King, we’ve designed our access control solutions with integration in mind, making it seamless to connect with our video surveillance systems and third-party security technologies.

Maintenance & Lifecycle Management
Like your car or home, your physical access control system needs regular maintenance to keep running at its best. Treat it as a living system that requires ongoing care and periodic updates.
Firmware updates are essential for security and functionality. Make it a habit to regularly update controller and reader firmware to address security vulnerabilities and add new features. I recommend checking for updates quarterly at minimum.
Credential management is another ongoing task that can’t be neglected. When credentials are lost, stolen, or expired, they need to be deactivated immediately. Maintaining an accurate database of active users isn’t just good practice—it’s essential for security.
Don’t forget about the physical components of your system. Schedule regular hardware inspections to check readers, locks, and door sensors for damage or wear. Small issues caught early can prevent bigger failures down the road.
If your system includes battery backup (and it should!), follow a regular replacement schedule before failures occur. There’s nothing worse than finding your backup batteries are dead during a power outage.
Finally, protect your data with regular database backups of your access control system. If something goes wrong, you’ll be able to restore your system quickly without losing critical information about users and access rights.
Looking further ahead, good lifecycle management involves planning for the eventual replacement or upgrade of system components. Most PACS hardware has an expected operational life of 7-10 years, though software and firmware updates can extend functionality. Creating a technology refresh plan helps ensure you have budget available when upgrades become necessary.
Compliance & Audit Readiness
For many organizations, physical access control systems play a crucial role in meeting regulatory compliance requirements. Depending on your industry, you might need to comply with standards like:
NIST Special Publication 800-53 which outlines security controls for federal information systems, or FIPS 201 which establishes standards for personal identity verification of federal employees and contractors. Healthcare organizations need to consider HIPAA requirements for protecting patient information, while those handling payment data must address PCI DSS standards. And almost everyone needs to think about GDPR and other privacy regulations that set requirements for protecting personal data.
To stay compliance-ready and audit-ready, start by documenting access policies thoroughly. Written policies that govern access control decisions provide the foundation for compliance.
Be diligent about preserving audit logs for the period required by applicable regulations—these are often your best evidence of compliance during audits. Set up regular compliance audits to review user accounts, access rights, and system configurations before external auditors arrive.
Don’t forget to test emergency procedures periodically. Verify that emergency override and fail-safe mechanisms work as intended—this is often a specific requirement in many regulations.
Lastly, invest in personnel training to ensure your staff understands compliance requirements related to access control. Well-trained employees become your first line of defense against compliance issues.
At Security Camera King, we understand these challenges. Our systems include compliance features designed to help organizations meet regulatory requirements while maintaining operational efficiency. We don’t just sell you equipment—we help you use it in ways that keep you secure and compliant.
Regulatory Landscape, Risks & Future Trends
The field of physical access control continues to evolve in response to emerging threats, technological advancements, and changing regulatory requirements. Understanding this landscape helps organizations make forward-looking security decisions.
When we talk with clients about their security needs, regulatory compliance often tops their list of concerns. The rules governing access control vary widely depending on your industry and location, but they generally focus on four key areas.
First, data protection regulations dictate how you must handle and safeguard the personal information collected by your access systems. Second, privacy considerations increasingly limit how organizations can collect and use biometric data, especially facial recognition. Third, if your facility falls under critical infrastructure protection mandates, you’ll face improved security requirements. Finally, interoperability standards ensure your systems and credentials work seamlessly across platforms.
The threat landscape is equally important to understand. According to the 2022 Cost of Insider Threats Global Report, insider incidents have jumped by a concerning 44% over the past two years. Even more alarming, the average cost per incident has reached a staggering $15.38 million. These statistics highlight why robust access control isn’t just nice to have—your organization’s security strategy.
Looking toward the future, we’re seeing several exciting developments reshaping physical access control systems. AI-improved analytics are revolutionizing how we identify suspicious access patterns, potentially flagging security threats before they materialize. The industry is also rapidly embracing mobile-first approaches, with smartphones increasingly replacing traditional access cards as the credential of choice.
Zero trust security models are gaining traction too. Rather than assuming someone is trustworthy after initial authentication, these systems require continuous verification—essentially treating everyone as a potential threat until proven otherwise. The pandemic accelerated adoption of touchless access technologies, and this trend shows no signs of slowing as organizations prioritize both convenience and hygiene.
On the technical side, quantum-safe cryptography is emerging as companies prepare for the security challenges quantum computing will bring. And finally, we’re seeing tighter unified physical/logical access integration, where building entry systems work hand-in-hand with IT system access for truly comprehensive security.
At Security Camera King, we don’t just sell products—we partner with you to steer this complex landscape. We continuously monitor these trends to ensure our access control solutions remain cutting-edge while maintaining the usability and cost-effectiveness our customers expect. As regulations evolve and new technologies emerge, we’re committed to keeping your security infrastructure ahead of the curve.
Frequently Asked Questions about Physical Access Control Systems
How do physical access control systems improve security?
When clients ask me about the real-world benefits of physical access control systems, I always explain that the improvements go far beyond just keeping doors locked.
First and foremost, these systems create a solid barrier against unauthorized access. Unlike traditional keys that can be copied at any hardware store, electronic credentials require sophisticated technology to duplicate. This immediately raises your security baseline.
The accountability factor is huge too. Every time someone uses their credential, the system creates a digital fingerprint of who entered where and when. This audit trail isn’t just useful for investigations after an incident—it actually prevents problems because people behave differently when they know their actions are being tracked.
I’ve seen the power of granular permissions transform security operations. One manufacturing client of ours used to give employees all-or-nothing access. After implementing our system, they could restrict access based on shifts, departments, and security clearance levels. Their internal shrinkage dropped by 40% in the first quarter alone.
The ability to instantly revoke credentials is a game-changer compared to traditional locks. I remember a university client who previously spent over $20,000 annually re-keying locks after lost keys. With their new physical access control system, they simply deactivate lost cards with a few clicks—no more emergency locksmith calls.
Don’t underestimate the deterrent effect either. The visible presence of readers and controlled doors sends a clear message to potential intruders that your facility takes security seriously.
Finally, these systems shine during emergencies. A pharmaceutical research facility we worked with configured their system to automatically secure sensitive areas during evacuations while keeping exit paths accessible. This balance of security and safety simply isn’t possible with conventional locks.
What types of physical access control systems are most common?
In my 15+ years in the security industry, I’ve watched the landscape of physical access control systems evolve dramatically, though certain technologies remain consistently popular.
Card-based systems continue to dominate the market, with about 60% of businesses relying on ID badges or cards as their primary access credentials. There’s good reason for this—they’re cost-effective, reliable, and users intuitively understand how to use them. Many of our clients start with this foundation before adding more sophisticated layers.
Mobile credential systems are the fastest-growing segment, now used by nearly a third of companies. The convenience factor is undeniable—people are far less likely to forget their phones than an access card. One property management client told me their tenant satisfaction scores jumped 15 points after implementing mobile access to their buildings. People simply love using their phones to enter buildings.
Biometric systems have found their sweet spot in high-security applications, with 30% of organizations now using them. While fingerprint recognition remains most common, facial recognition is gaining popularity, especially since the pandemic made touchless solutions more attractive. A data center we equipped with multi-factor authentication (card plus fingerprint) hasn’t had a single unauthorized access incident in three years.
Simple keypad systems still have their place, particularly for lower-security areas or as a backup authentication method. They’re intuitive and require no special hardware for users to carry.
For vehicle management, license plate recognition has transformed parking security, with a quarter of organizations now using this technology. One corporate campus we worked with eliminated long entry lines by implementing LPR, improving employee satisfaction while maintaining tight security.
The most effective approach I’ve seen combines multiple technologies custom to specific areas based on their security requirements. This layered strategy provides the right balance of protection and convenience throughout your facility.
Are physical access control systems difficult to maintain?
When clients ask about maintenance requirements for physical access control systems, I always start by discussing their deployment model, as this significantly impacts the ongoing workload.
Cloud-based systems have dramatically simplified maintenance for most organizations. Software updates happen automatically behind the scenes, much like your smartphone apps. System health monitoring is handled by the service provider, often detecting and resolving issues before you even notice them. User management—adding employees, changing access levels, or removing departed staff—can be done through intuitive interfaces from anywhere with internet access.
One retail client with 23 locations switched to our cloud-based system and reduced their access control maintenance time by over 80%. Their IT team couldn’t be happier to focus on more strategic projects instead of server maintenance.
Traditional on-premises systems typically demand more attention. Your IT team will need to handle software updates, database maintenance, server health, and regular system backups. While this gives you complete control over your system, it does require dedicated resources and specialized knowledge.
Regardless of deployment model, some hands-on maintenance is unavoidable. Readers and door hardware live in the physical world where they face weather, wear and tear, and occasional damage. We recommend quarterly visual inspections of all hardware components. Backup batteries should be tested semi-annually and replaced according to manufacturer schedules—usually every 3-5 years.
Door hardware like electric strikes and magnetic locks will eventually need adjustment or replacement due to mechanical wear. These components typically last 5-7 years with proper maintenance.
At Security Camera King, we’ve designed our systems with easy maintenance in mind. Our cloud solutions include proactive monitoring and automatic updates, while our on-premises options feature intuitive management tools to simplify necessary tasks. We also offer comprehensive support services for both approaches, ensuring your system remains both effective and efficient throughout its lifecycle.
Many of our clients find that the maintenance requirements are far outweighed by the time saved through automated access management. As one property manager told me, “I used to spend hours dealing with keys and locks every week. Now I handle access changes in minutes from my phone, even when I’m on vacation.”
Conclusion
Stepping back to look at the big picture, we’ve come a long way from the simple lock-and-key systems of yesterday. Today’s physical access control systems offer sophisticated protection that goes far beyond just controlling who enters your building.
Modern access control doesn’t just keep the wrong people out – it creates detailed records of who went where and when, works seamlessly with your cameras and alarms, and adapts as your security needs evolve. It’s security that works intelligently rather than just standing guard.
Throughout our journey exploring access control, we’ve seen how today’s systems offer impressive flexibility:
You might choose the convenience of smartphone credentials that let employees enter with a device they already carry. Or perhaps the improved security of fingerprint or facial recognition makes more sense for your sensitive areas. Cloud-based systems can free you from IT headaches with automatic updates and remote management, while thoughtful integrations create a security ecosystem where your cameras, alarms and access control work as a unified team.
At Security Camera King, we’ve helped hundreds of businesses across Boca Raton and throughout the country find their perfect security match. We understand there’s no one-size-fits-all solution – your ideal system depends on your specific security requirements, budget realities, existing technology, and how your business actually operates day-to-day.
If I could leave you with a few key insights from my years in the security industry, they would be:
First, really assess what you need before shopping for solutions. Consider not just today’s requirements but where your business is headed in the next few years.
Choose authentication methods that match both your security needs and your culture. The most secure system in the world fails if it’s so cumbersome that employees prop doors open to avoid it.
Look beyond the initial price tag to understand what the system will cost you over its lifetime, including subscriptions, maintenance and eventual upgrades.
Develop clear, sensible access policies that people can actually follow, defining who needs access to which areas and when.
Plan how your access control will work with your cameras and other security systems for maximum effectiveness.
And finally, commit to maintaining your system through regular updates, proper credential management, and hardware checks.
Physical security isn’t something you install once and forget about. It’s an ongoing commitment to protecting what matters most – your people, property, and business assets. By thoughtfully implementing the strategies we’ve discussed and working with experienced security professionals, you can create protection that strengthens rather than hinders your operations.
