Video Surveillance Systems

Monday, January 9th, 2012

Many business and homeowners are turning to video surveillance systems for continuous monitoring of property and premises during those times when they can’t be physically present. Today’s systems are generally easy to install and use, eliminating the need for expensive professional expertise or the downloading of additional software.

video surveillance systemsCameras are available in both wired and wireless configurations. While wired systems are regarded as somewhat more reliable and trouble-free because of the lack of reliance on batteries and routers, wireless solutions offer some interesting benefits.

There are no wires to hide, and these systems be operated through an existing local area network. Cameras designed for outdoor use will withstand wind, rain, snow and temperature fluctuations better than their all-purpose counterparts.

PC-based Systems

Among the most popular choices are those systems that can be monitored using any of the more common Web browsers on a remote PC. They don’t require having a dedicated PC onsite, saving money and the hassle of maintaining and securing yet another device. These video surveillance systems assign a specific IP address to each camera, so you’ll always know exactly what you’re viewing when you’re at home or on vacation. You won’t have to guess where an intruder has entered because Camera A points directly at a particular door and has sent you a picture as he enters the building.

Each camera also has its own email address preinstalled. Choose models that have preinstalled motion detectors that email you only when someone enters a sensitive area of your home or business. Footage can be viewed in real time or can be stored and then viewed later.

Images are emailed to you in .jpeg format for fast downloading to your computer, no matter if you’re using a Mac OS, Linux, or Windows. Industry standard automatic configurations allow each router and computer to determine the optimum settings for your system, reducing endless the endless tweaking and resetting required for capturing the clearest images.

Choose a video surveillance system that operates in both daylight and in low-light environments. Vandals and thieves don’t normally strike at night. These are an excellent security solution when it’s not convenient or cost-effective to a security on duty around the clock.

Business Security

Business owners choose remote cameras keep tabs on sensitive areas in real time, tracking employees’ movements in and around sensitive areas such as operations and financial offices. Video surveillance footage can provide a completely different story than that recorded by business computers that can’t furnish real-time reports.

Using video surveillance technology to monitor a business’ premises is the modern-day equivalent of Management By Walking About popularized in Tom Peters’ In Search of Excellent more than 20 years ago.

*A company’s LAN access to run its security cameras is one of the most underused capabilities today, one within the reach of even the smallest business.

*It’s inexpensive, and keeps a visual record more reliable than the blurry inaccurate memories of onsite personnel.

*Digital Video Recorders, or DVRs, document activity in shipping areas, loading docks, sales areas (especially point-of-sale terminals), public areas to monitor loiterers who may be shoplifting, and truck and customer parking areas.

There’s a good chance that nearly any business can become the target of a disgruntled employee or customer rampaging through a store or office, destroying property in retaliation for a real or imagined slight. At the same time, a video surveillance system can reduce vandalism to outdoor furnishings and landscaping or detect a criminal lurking in an ill-lit and remote parking area.

Home Safety and Security

Homeowners with families are also immersing themselves in the capabilities afforded by video surveillance cameras.

*Nanny cams and outdoor security cameras are the most common uses for this technology in the home.

*Expand your horizons and monitor what’s going on both inside and outside your home — what the postal carrier is doing when he or she is delivering the mail, the neighbors’ filching water or gasoline or the lawn care company’s activities when you’re away from home.

You can monitor your home while on vacation, spot a burglary in process, call law enforcement while the crime is in progress and watch the criminal’s reaction when he’s caught in the act. Once your property is known as having video surveillance capability, potential criminals will give your home a wide berth in the future.

*Nine out of ten home security systems are used for deterring property crimes such as burglary and vandalism.

*Four out of ten systems are used for deterring and detecting violent crimes such as robbery, assault, abuse, rape and murder.

Video Monitoring of the Elderly

On the other hand, video surveillance has a more benign and caring side. While 24/7 surveillance of a loved one is not really something most of us want, it’s comforting to have surveillance cameras located in critical areas within the home.

*Place one in plain sight in the kitchen to alert you to Mom’s or Dad’s daily eating habits and safe kitchen practices.

*Place a camera in the hallway outside the bathroom or bedroom to ensure your parents’ ability to perform daily living functions and alert you to possible health issues.

Video surveillance capabilities inside the halls, lobbies and elevators of a senior-citizen housing complex serve the same purpose. Residents retain a high degree of independence, but still benefit from concerned oversight. For example, security personnel can be alerted to the presence of suspicious loiterers presenting mugging or robbery threats. At the same time, residents who fall or become ill in public areas receive medical assistance more quickly than if they were unmonitored.

Law Enforcement and Insurance Companiesvideo surveillance systems

Law enforcement agencies are turning increasingly to video surveillance systems to monitor public disturbances such as looting and vandalism.

*A police force may be overwhelmed during the initial stages of a riot and the identification and prosecution of the instigators may prove difficult or impossible without surveillance footage.

*Building owners’ surveillance cameras often provide valuable information and evidence that help put malefactors behind bars.

*Footage can be useful when filing insurance claims after a disturbance.

Location Considerations

While many cameras are located in plain sight in these situations, it’s often better to select units that can be hidden behind something else if you’re using them for security surveillance purposes. They can be located behind paneling or a wall surface, inside home furnishings, or in out of the way corners of the workplace. This cuts down on criminals’ finding cameras’ blind spots and capitalizing on them, or even inactivating them or destroying them before breaking in.

Commercially installed video surveillance systems offer the benefit of expert analysis of specific requirements and camera placement. Blind spots are eliminated, or identified and resolved.

Owner-installed PC-based remote monitoring capabilities need to address similar concerns. Select one of these inexpensive solutions that includes up to 64 cameras with individual discrete IP and email addresses and motion-detecting functions.

Ethical Considerations

Ethical considerations must be observed. Video surveillance technology is a valuable tool in deterring crime and ensuring the well-being of our most vulnerable citizens.

Hiding a video camera and recorder in a public area to protect it against damage is one thing. Secreting a hidden camera in a public restroom or locker room is quite another thing. When pondering the advisability of placing a video surveillance system in the home of an elderly parent, his or her wishes need to be respected. Compassionate monitoring should not be equated with micromanagement and interference.


The choice between professionally installed technology and a do-it-yourself PC-based system is often determined by a variety of factors, with cost lying near the top of the list. In a challenging economic environment, even the most cash-strapped business or homeowner can take advantage of inexpensive, and highly reliable security video monitoring.

video surveillance systemsVideo surveillance technology offers big dividends in the form of securing sensitive business data, safeguarding cash receipts during the course of the business day, reducing pilferage in stockrooms and loading docks and deterring vandalism. Even small businesses can take advantage of low-cost video surveillance solutions when they opt for Web-based camera images.

Homeowners can take advantage of PC-based video surveillance as part of a comprehensive home security program or as an additional security layer when they’re away on vacation.

Simple PC-based video surveillance plays an important role in safeguarding the well-being of an elderly parent who lives in another city or state.

Small senior-citizen housing facilities provide enhanced security to their residents when video surveillance systems are in place. Injury, illness and crime are addressed quickly and appropriately.

Law enforcement agencies and insurance companies benefit from the use of home and business video surveillance footage when solving a crime or settling a claim.

Proper placement of cameras is crucial in the success of these systems. Purchase as many cameras as your budget allows, and then locate them to cover areas with controlled access to sensitive areas of operation.

Choose a system with both day and night capabilities.

Video surveillance can’t replace human security personnel completely. On the other hand, a system that incorporates at least some video recording capability has the advantage of providing a sharper record than the memories of flustered and perhaps biased employees.


CCTV Multiplexer

Tuesday, July 5th, 2011

A CCTV multiplexer or Closed Circuit TeleVision Multiplexer allows more than on camera to be connected to the unit but only one output at a time is allowed through the unit.  Most Digital Video Recorder or DVR units have this function built right in to the DVR.  Another way to describe a multiplexer is by its function which is to combine various input signals and generate only one output signal.  You can almost think of a CCTV Multiplexer as being similar to a computer router.

For digital video security and surveillance systems, the multiplexer is what allows the display of 8 cameras simultaneously.  Eight video transmission cables from eight individual cameras connect to the multiplexer.   The multiplexer then takes the 8 individual camera inputs and combines them into one.  This how you are able to view 8 digital video security and surveillance system cameras on one monitor.

A CCTV multiplexer works by allocating bandwidth; this highly refined process insures that the transmission medium is used efficiently.  There are actually four different methods of multiplexing:

* Space division;

* Frequency division;

* Time division; and,

* Address multiplexing.

Generally speaking, digital transmission uses time division multiplexing and analog transmissions use frequency division.

In applications like cable TV each channel the user visits is broadcast on the input cable at a different frequency.  But with a CCTV application however, since the cameras are all on a closed circuit, all use the same frequency.  With each camera broadcasting at the same frequency there would be no doubt of the signals getting jumbled up, interference, and cross talk.  Literally, about the only way to handle that situation would be for every camera input to have its own monitor.  In other words, a 16 camera system would require 16 separate monitors.  CCTV multiplexers were designed to put as many cameras as possible on one monitor and reduce the user’s cost by relieving the need for the same number of monitors as there are cameras.

Multiplexers are available in a variety of sizes.  Since the DVR often contains the multiplexer, the multiplexer can be custom designed within the DVR unit itself via the manufacturer of the DVR.  However separate, external multiplexers are still available and used today in about three different configurations based on the number of cameras (channels) that are being used.  Common sizes for stand alone multiplexer units are 4, 8, 16 and 32 channels (camera inputs).

Setting up a multiplexer is rather easy and doesn’t require much prior knowledge of digital video security systems.  Some multiplexers do have a few different features that you will need to activate if you want to use them.  These may include the ability to view one channel at a time or all or multiple channels at the same time.  Some units may also have a “dwell” setting.  Dwelling is the term applied to multiplexers that describes the ability to display a particular camera for a certain period of time before showing the next cameras.  This process is repeated cyclically as the multiplexer moves through each individual camera one at a time.  This is also known as “dwell time.”

Some CCTV multiplexers not only can dwell, but some also come with a hand held remote control that allows the user to stop or move-on a particular camera in the system.  Setting the multiplexer up for use with these features is usually accomplished with On Screen Displays or OSD that make the set even quicker and easier.

In the past, CCTV multiplexing was not an option but was a definite requirement if you wanted to see more cameras than just one on a monitor.  Today, with LCD and LED monitors multiple camera viewing is very easy.  Now the only question is how many cameras do you want to view at once?  Of course this is dependent on your DVR which ultimately means, dependent on the multiplexer built into your DVR.

Be sure to check the specifications of the DVR or CCTV multiplexer to make sure that everything is compatible before making your purchase.  If you have any additional questions on multiplexers, please contact one of our security experts via on-line “Live Chat” or by telephone at 866-573-8878 Monday through Friday from 9AM to 6PM EST.


CCTV Video Software

Friday, February 11th, 2011

There are many types of Closed Circuit Television or CCTV video software. Although the term “CCTV video software” doesn’t actually refer to any specific type of digital video security and surveillance software, we’ll take a look at a few of different examples and see what they can do.

For the purpose of our discussion here, we’ll try to classify CCTV video software into two different categories. The first will include software that enables personal computers and accompanying peripheral devices (such as web cams) to act as a digital video security systems. The second category will include software that is used for different functions on digital video security systems, (such as track or follow).

Since video security and surveillance systems have become totally digital, there is a lot of crossover with the computer world. The digital video security community has been able to reap the benefits of the exponentially increasing technology improvements in the computer world, and can even adapt personal computers to act as digital video security systems using the right components and Closed Circuit Television or CCTV video software.

While using a personal computer is enticing, there are certain limitations that still exist if this is done. Generally, digital video processing is one of the most taxing tasks for computer processors to perform because of the incredibly large amounts of data involved with creating high-quality digital video files. Therefore, the Central Processing Unit or CPU of a personal computer can slow down tremendously while trying to operate digital video security camera functions and perform other routine computer tasks. Nevertheless, there are CCTV video software programs that will adapt a personal computer and one or more webcams to act as digital security video systems.

A more popular method of using CCTV video software on a personal computer is the use of a PCI card and actual cameras designed for digital video security systems. This method allows the use of typical digital video security cameras with a personal computer, but reducing the processing load on the computer’s CPU drastically so as (hopefully) not to affect its performance considerably.

The PCI card often contains the Integrated Chip (IC) technology that provides for a Digital Signal Processor or DSP that pre-processes the data sent by the digital video cameras. Many PCI systems also contain a storage disk on the PCI card to alleviate the need for using the personal computer’s hard disk drive. For these systems, CCTV video software provides for the drivers needed for the PCI card and other peripheral devices and instead of handing the CPU all of the work, it utilizes it more to coordinate the work between the computer and the PCI card.

Another facet of CCTV video software design and also one of the most recent includes software that allows digital video cameras and entire digital video systems to use the Internet as a vehicle for networking and accessing. The devices that are used specifically for this purpose in digital video security systems are usually referred to as IP ready or Internet Protocol ready devices.

Although the CCTV video software that makes IP devices possible may not necessarily be installed on a personal computer per se, it does often accompany the device, either in the form of built in programming, circuitry or as Internet browser “add-on.” As for IP ready cameras, the CCTV video software provides web server technology so that the camera may connect directly to the Internet. Using a personal computer with a Web browser and an “Ad-on” program, an individual can monitor, control, and record the camera’s video images to a personal computer by using the Internet as the vehicle for networking.

The second category of CCTV video software is programming that is used to control the camera, DVR, and other devices. This software usually resides on the DVR unit and works with the units DSP to control and coordinate the individual devices. For example, Pan-Tilt-Zoom or PTZ cameras can move horizontally, vertically, and enlarge views. The mechanical movements for these cameras are usually controlled by software that resides on the DVR unit.

Not only can PTZ cameras make those mechanical movements and manipulations remotely using software, but they can also be done automatically using special CCTV Video Software. Furthermore, the software can be used to detect objects moving, and direct the PTZ functions of the camera to track or follow the object’s movements.

It would appear that the potential for CCTV video software is limitless, especially now that we live in the digital age.


Home Security Camera Motion Sensitive

Monday, December 27th, 2010

One of the most effective residential digital video security systems is the home security camera motion sensitive. This camera not only conserves recording time and power resources put can effectively act as an alarm unit, only recording when motion is detected.

There are basically two types of home security systems, digital video security camera systems and security alarms (intrusion alarms). The home security camera motion sensitive combines the advantages of both systems into one by only recording video only when motion is detected. Not only does the owner benefit from digital video documentation of a potential criminal perpetrator inside the home, but if the system is connected to the internet, an email alert can be sent immediately to the owner’s smartphone notifying them of the intrusion.

If the home security camera motion sensitive is used outdoors, (i.e. is an outdoor type digital video security camera) it can also be used to notify the owner of the presence of someone on or approaching the residential property. Cameras of this type are commonly used on extended driveways or gated property/driveways. They can alert the homeowner of a visitor, long before the visitor arrives at a door.

The home security camera motion sensitive is a digital video camera with a built-in Passive InfraRed (PIR) sensor. The PIR scans the camera’s field of view for a differential in heat signatures, such as that caused by a person walking into the PIR and camera’s field of view. When the PIR detects the change in infrared radiation, it interprets this to indicate motion.

The PIR is connected to a relay inside the camera housing. When the PIR senses motion, it triggers the relay to turn the camera on and begin recording. The camera stops recording either when the PIR no longer detects motion or after a pre-programmed time delay. When the camera is battery operated, the PIR conserves battery life (or time between recharge cycles if the batteries or rechargeable) since the electrical drain caused by the PIR function is drastically lower than that needed for the camera to capture video.

There is also another type of home security camera motion sensitive system. The camera for this system is also on and capturing video images. However, the Digital Video Recorder (DVR) and Digital Signal Processor (DSP) are programmed to recognize changes in the video image of the camera’s field of vision. When this occurs, the DVR begins recording as long as the motion is detected. However, this system uses a non-motion sensitive camera and does not offer the advantage of power conservation as does the home security camera motion sensitive.

Residential digital video security systems are incredibly versatile in application these days thanks to improvements in camera, electronics, and computer technology. There are many additional optional features available for home security camera motion sensitive. The following is a list of some of the more common optional features available:
• Day/night vision cameras. These cameras are very sensitive to light such that they can still produce high quality color video in very low light conditions.
• Night vision infrared cameras. These cameras use infrared illumination which is invisible to the human eye to produce high-quality black and white or monochromatic video in total darkness.
• Outdoor cameras. These cameras are designed with a protective enclosure for the purpose of preventing damage to the camera from exposure to weather and other elements (dust for example).
• Wireless cameras. These cameras send their video transmission data using radio waves instead of cables. Using these cameras eliminates the need for an RG-59 coaxial cable to be run from each camera to the DVR. There are also battery operated cameras of this type creating a truly “wireless” camera.
• Internet Protocol (IP) ready cameras. These cameras contain built-in web server technology and can use the internet as a vehicle for networking. Furthermore, these cameras can be monitored anywhere in the world where broadband internet access is available (including 3G and 4G smartphones).
• Hidden or disguised cameras. Camera technology can produce such small digital video cameras that they can be hidden or disguised as another object.

The various features in addition to the motion detector makes the home security camera motion sensitive one of the most effective residential digital video security cameras.

Security Alarm Systems and Security Equipment Products

Tuesday, November 2nd, 2010

Security Camera King, in addition to digital video security systems, offers a full line of security alarm system and security equipment products. This includes counter surveillance, personal protection, and audio recording devices. Supplement your digital video security system with additional security alarms system and security equipment to maximize your protection potential.

If you are looking for cost effective security alarm system and security equipment products to supplement your digital video security system or to use as a standalone alarm system without digital video security, Security Camera King suggests our HomeSafe Wireless Home Security System. This system includes a wireless motion detector and a wireless door/window sensor, a keychain remote control for arming and disarming the alarm system, an AC adapter, and of course a central control panel.

Like most security alarm systems, the HomeSafe Wireless Home Security System works by placing sensors on accessible doors and windows (usually the doors and windows on the first floor). The door/window sensor (often referred to as a point or zone) can detect vibration or door/window opening and will notify the central control panel if that event occurs (often referred to a trigger). However, instead of running a wire from each sensor to the central control panel, this system uses wireless technology to enhance the performance of the system and make do-it-yourself installation quick and easy.

The central control panel can handle up to a total of 9 zones or points (sensors). (Security Camera King sells additional sensors as part of our security alarm system and security equipment products.) When any of the sensors are triggered, the sensor sends a signal to the central control panel. The panel then initiates a 105 dB alarm.

If you opt to connect your unit to your telephone line, the central control unit will, in addition to activating the ear piercing alarm, automatically dial up to 5 telephone numbers. When the first pre-programmed telephone number answers, a pre-recorded message will be played. Plus, that party will have the option of listening in on the room, broadcasting their voice through the central control unit, or disarming the system. If the first number dialed doesn’t answer, the unit will continue by dialing the second number and so on.

The central control unit has a 16 digit display that includes date and time and is easy to setup and program. It also provides for remote arming and disarming by telephone. The unit also uses a standard 9 volt battery (not included) for backup in the event of a power failure.

Security Camera King also offers counter surveillance devices as part of our security alarm system and security equipment products. Our Wired or Wireless Camera Multifunctional Detector can “sniff out” radio frequencies emitted by cameras and microphones ranging from 1 MHz to 6 GHz. This device also includes an LED signal strength meter and audible or vibrating alerts. In addition to radio frequency detection, this device also uses laser visual detection to find camera lenses, from wired or wireless cameras, up to 10 feet away.

Security Camera King also has bug detectors as part of our security alarm system and security equipment products. These detectors cannot locate the bug, but they can tell if there is one anywhere in the immediate area by “sniffing out” 1 MHz to 3 GHz radio frequencies.

We also carry a wide selection of various personal protection equipment including:
• Airsoft guns
• Animal repellent
• Car safety devices
• Diversion safes
• Folding knives
• Handcuffs
• Mace Pepper Sprays
• Personal alarm devices and
• Tasers and stun guns.

If you are looking for audio recording devices we offer two 576 hour digital phone/room recorders. These are professional grade recorders that also have a built-in FM radio. Voice activated, Line-In input, and MP3 encoding are just some of their available features.

So remember, Security Camera King doesn’t just sell digital video equipment but we sell a variety of security alarm system and security equipment products.
