Security cameras have been around since Woodstock. In the 1960’s banks all over the United States began using cameras for securing their perimeters. In the 70s, the Akai security system used a monochrome camera connected to a reel to reel VTR to preserve data. Later in the 90s multiplexing was introduced allowing the viewing and recording of multiple video signals, motion only recording and time lapse video. We all know what capabilities computers gave us for recording data to CDs, DVDs, Flash drives and large capacity hard drives.

Cameras Securing Court Houses

Sheriff deputies are usually guarding the court-house front. They count on instinct when judging someone’s character, whether it’s a high-profile criminal or an enraged victim. Court house guards need to have their eyes peeled at all times, and using CCTV camera systems is one of the real-time observation tools they use to accomplish this very difficult task.

Security cameras have the responsibility to keep judges, lawyers, prosecutors, the public, inmates and reporters safe when attending all court proceedings. Monitoring these cameras are dedicated technicians looking out for the unexpected.  Bond hearings, motions, and sentencing can now be recorded and saved into the courthouse database. Security cameras also help to secure prisoners to and from the intake of the court-house.

Security Cameras in Jails

Using security camera monitoring in jails has been around for a while now. Older systems were composed of analog cameras wired to an analog TV monitor with no recording, then came BETA MAX and VHS/VCR tape recorders with NO long-term recording capabilities.

Now in the new world we can record to hard drives that have virtually endless storage space. When there’s a conflict in question, the jail’s security camera recordings never lie. The security cameras allow 24 hour monitoring inside and outside inmate receiving, housing, cafeteria, elevators and every area that needs to be surveyed. Inmates are even going to court and seeing the judge via camera –to- monitor configuration. Visitation is dealt with a 2 way video and audio telephone system, you see the inmate through a screen and speak with a telephone.

House Arrest

House arrest is a different option for adult and juvenile offenders that have been arrested for a crime that qualifies the inmate under state and federal statues to be placed on some sort of monitoring system like an ankle bracelet or visits from certified state or federal officials to check on the inmate on a scheduled basis, questioning relatives, harassing landlord’s, employers and wasting time playing detective.

I truly believe that Security Cameras are the future of offender supervision using new IP camera digital video and audio viewing and recording technology. It takes time, money, resources, approvals and a telephone line to monitor a House Arrest prisoner, using an Ankle bracelet that should be tamper proof, but if a criminal really knows what they’re doing, they can bypass the security by either slipping out of the bracelet or disabling the Bluetooth radio receiver unit.

TechPro Security Products can now recommend a new and innovated thinking outside the DVR BOX and offer a cost, time and serious monitoring effective tool to get the job done. Its more than likely people tend to have Internet at their home then a telephone line, so installation of IP Supervision Cameras would be a breeze. Step 1 evaluate house arrest inmates internet status. Once established Step 2 a certified IP camera network specialist would install and configure the IP Cameras for the state or federal official to remote view, access and record to a secured cloud based server.

Adult and juvenile offenders arrested for crimes can have a term imposed on their bond, like not leaving the county or home, so the court elects home detention. Well what better way to monitor a person confined to their home then by using a camera design to supervise the accused person on release or bond. Imagine the peace of mind that the victim and bail bondsmen would have if they implemented IP Cameras mandatory installed in the offenders certified place of residence, or a sex offenders probation officer really knowing if his offender is telling the truth. Real Time Observation and recording is the answer. Safer, Braver and Stronger is the way to go.

Probation and Parole

Probation or Parole depending on a the state or federal prosecutors deal or contract, substitutes the inmates time in prison for close probation or parole supervision, but how is the probation officer supposed to supervise all those violators at the same time? TechPro Security IP Technology using IP Cameras to monitor Probation or Parolees is the answer. When offenders checking in is a hassle, you can observe violators under court ordered supervision at any time using TechPro Security PSS software. Is the Probation or Parolee drinking or partying, who’s really living at the supervised inmate’s residents and what friends are really visiting the Probation or Parolee? Offenders are more than likely to not invite BAD acquaintances over if their home is being monitored and recorded by a certified official’s server.

Sex Offenders

Registered sex offenders classified as court ordered repeat offenders can now be monitored 24 hours a day 7 days a week using IP Security camera technology, all you need is Internet access at the registered sex offender’s home. Security cameras are a big deterrent, if you think someone is always watching you, you will be more than likely not to commit a crime. Probation and parole officers can now demand a pop up check in on demand via real-time IP Cameras at a local location, checking in with a probation or parole officer has never been easier. Security cameras monitoring pedophiles would increase children of all age’s safety.

Police Car Cameras

Analog Cameras have been recording police evidence to tape recorders for years now, with all the new Megapixel technology cameras authorities can really use unedited and unaltered video and audio recordings real-time uploaded to the cloud for evidence. Lawyers and prosecutors have used police captured footage entered for evidence in big cases. The recorded footage helps eliminate any false accusations against the police officers and the detained individuals. Police cameras record events like DUI tests, police chases, speeding, auto accidents and arrests. Police cars now have cameras capable of scanning license plates for expired and suspended licenses. Mobile cameras have been recording streets and location points for Google map for years, mapping our city streets for GPS software. Cameras are even looking out for red light runners and traffic violators. K9 police and military dogs are even getting in on the wireless remote camera view, not excluding the new drone technology, that’s another subject in its self. The future of authorized supervision are IP Cameras.

police camerapolice car wifi

I can see the future of remote security access record and viewing. Imagine a business like a restaurant or bar that has a full security camera system that has been configured for remote access using an external IP address and there is a hold up and the manager hits an alarm or calls 911 and the data sent is accompanied by the external IP address of the business security camera system and the officer in route can pull up the cameras in the police cars laptop. The advantage of seeing the inside of a dangerous situation is priceless! If the criminal flees before authorities get there they still can view recorded footage and track the offenders direction of departure giving the police officer a heads up to track the suspects down. I can’t wait to see what the future holds for Security Camera Technology.

CCTV Installation and Wiring Options

CCTV Installation and Wiring Options

Today there are a lot of options when it comes to choosing a quality CCTV security system. You may decide to go with a traditional analog system, HD-SDI, HD-CVI or even an IP network based security products.

One thing all of these options have in common is you will probably have to run some sort wire to the cameras. Yes, there are some “Wireless Security Camera” solutions available on the market today, but if you do some research you will find that there are a lot of limitations to wireless security cameras. Most CCTV professionals would probably not recommend a wireless system in an environment where up-time and security are critical.

install

I do want to mention that it is possible to reliably transmit video wirelessly using a device such as the TP-LocoM5 – Wireless Access Point/Bridge as seen here at www.securitycameraking.com.

But even then you would still need to have a power wire run to the camera or a local power source near the camera and it only works with IP Cameras.

That being said, we will be talking about a fully-wired system in conjunction with a storage device such as a DVR (Digital Video Recorder) or NVR (Network Video Recorder).

NEW INSTALLATION
When installing a completely new security system you may want to have the video and power wires come from a single location located near the storage device (DVR or NVR) as shown below.

ANALOG SYSTEMS
Analog, HD-SDI and HD-CVI cameras will need two wires run to them. One for video transmission and a set of power wires in order to power the camera. You could run a coax wire and separate power wires but most CCTV professionals choose to use “Siamese Cable”. Siamese Cable is a manufactured coax cable with a set of power wires attached to it. The power wires can be split off from the coax in cases where your power source may not be in a close proximity to your recording device.

Siamese-Cable

NETWORK IP SYSTEMS
IP cameras use digital video transmission over CAT5 or CAT6 cable. In most cases you run your video and power to and from the camera on the same CAT5 or CAT6 wire, assuming you are using a POE (Power Over Ethernet) power source such as a POE injector or POE Switch.

Some NVRs come with built in POE,  but in most cases it is recommended to use an external POE switch like the POE-8MB1G from SecurityCameraKing.com. When using an external POE switch all of your CAT5 or CAT6 will run directly from each camera to a POE switch that is connected to your local network. Then you simply connect your NVR to the network and you are all set.

POE-Setup

Most IP cameras also come with an additional power wire if you choose not to use POE and power them with 12v or 24v power as shown below.

IP-Cable

If you are going to power your IP camera with 12v /24v power  you will still run all of your CAT5 or CAT6 from the camera to a Non-POE switch (usually significantly less expensive than a POE switch) but you will run an extra set of power wires from a power source to each camera.

NO-POE-Setup

RUNNING YOUR CABLES

Now it’s time to run your cable. The following will cover 2 popular scenarios.

Scenario 1: Running your cable through your attic and mounting your cameras to the soffit. This is a common installation option, provided you have access to your attic and your soffits are also accessible.

First you have to choose the placement of you recorder and power supply. Some people simply have them located in an office or a room within their home.  Others prefer having them in a more secure location such as in a lockbox, hidden in a closet, or even in the attic itself.

The image below shows the recorder and power supply inside a room of the home. Power and video wires run up the wall into the attic to the location where the camera will be located and out a small hole in the soffit were the camera will be mounted.

sOFFIT

Scenario 2: Another option is to run your cable through an exterior wall and then use conduit on the exterior of your structure to run your cables from one camera to another. This is a great option for those who do not have an attic or limited access to one.

Junction

Mounting Your Cameras

Once you have run your wires to the desired location you can connect your camera. In some cases where the cables are coming out of the soffit it is possible to connect your wires together and tuck the connections up into the hollow area of the soffit, then mount the camera directly to the soffit.

Direct-soffit-mount

In situations where you’re running your wires through a solid concrete or brick wall that the connections cannot be tucked into, it is common to mount a junction box.

Junction

Junction Boxes and Conduit
Junction boxes are particularly useful when running your cable through conduit on the exterior of your structure as they serve as a weather proof container protect your power and video connections from the elements and also provide you with a flat surface to mount your cameras to.

Box1

First you will pull your wires through the access hole on the back of the junction box. Then mount the junction box to the wall. You may have to drill a hole in the junction box cover big enough to feed your camera connections through. Next, connect the camera to the power and video connection(s). Then screw the cover on to the junction box. Now you can mount you camera to the junction box. See the diagram below.

JB

When used on a soffit, a junction box will sometimes be helpful in order to lower and drop your cameras below obstructions such as deep fascia boards as shown below.

CCTV-FAQ

Learning about our DVR’s can help you better understand them and allow you to do the more advanced functions, but first you need to learn the basics. Not just the basics but also things that can make setting up the DVR an easier process. This CCTV FAQ is a continuation of last months article that will further explain these functions in detail. This article will go through basic functions like creating a new user and adding an IP camera, to more advanced functions like changing the IP of a camera and enabling tour. This article can be very useful for Dealers, Installers, and the average consumer. It helps explain simple tasks that you could only learn by earthier digging through the User Manual or through experience of using the device.

1. How to create a new user and apply permissions.

With surveillance equipment it is best to know who is accessing your system and who can access it. Creating different users with different permissions will help prevent any tampering and will help narrow down what people are using the device for. To start, the DVR comes with Users built in that can be used but the best thing to do is to start fresh and create all new users with the permissions that you want them to have. The way you do this is by going to Main Menu>Settings, and then Users. In this area you will see the different users on your DVR and by default there should be 4. To add a new one you just click Add User. Here you enter the users Name and Password as well as what group you want to place him under. These groups give predetermined permissions that can be useful if you set up the proper group. If you want to manually adjust a user’s permissions you can do that below. After you are satisfied with that specific user you can click save. If you want multiple users with the same permissions without have to adjust each one you can create a group. After you create a user account for everyone who will be accessing your DVR you can track and log all activity that is happening in realtime.

2. How to setup an IP camera to transmit snapshots to a FTP server.

Having IP cameras allow you to not only record to a NVR but it also allows you to record to a local or remote server. This allows you to use the camera as a standalone unit or to create off-site storage for extra security. It gives you the feature for when there is any motion on the camera it will upload a small clip or a snapshot to your FTP server. For this article I will be referencing the IPOD-EL1MPIR50. To start you need to log into the camera’s web service through Internet Explorer with its default IP 192.168.1.108 username: admin Password: admin. Once logged in you go to Setup>Camera>Video, and then Snapshot. There is a drop down menu next to Interval that will allow you to make the camera take snapshots every 1 to 7 seconds. On this page you can also adjust the quality of the snapshots. Just make sure you click Save at the bottom of the page to apply any changes you have made. After that you need to set up which days and time periods for the snapshots. On the Menu bar to the left click Storage>Schedule, and then snapshot schedule. Click the the setup button on the top right of the time bar and here you will be able to adjust those settings. Choose what days you want to have this feature set for and if you want it for everyday just click Select All on the upper left corner. If you want it based off motion you can just click save but if you want 24 hour then to the right of Period 1 click General.

Now that we have that set up we can configure the settings for connecting to the FTP server. Under Storage on the menu on the left click on Destination. Make sure that your in the Path tab located on the top. Under snapshot on the right side of the screen make sure that the Schedule box is the only one selected and then hit Save. Next select the FTP tab on the top of the screen so we can adjust the settings. To start, Server IP is where you enter the IP address of your FTP server that you are going to be connected to. If you are connecting from outside your network you are going to use your outside IP that your modem is using. Next Port is where you enter your listening port which is usually by default 21. Under username enter the username that is created on you FTP server. Then enter your password that correlates with that username. Last, under Remote Directory this is going to be the name of the folder the snapshots will be stored in on your server. As soon as you complete this step and it’s done correctly, your camera will start to transmit the snapshots to your FTP server. Based on how you set the time interval and whether you have it on motion or 24 hour.

This article was created to help people understand their DVR’s, NVR’s and cameras better so you can do more with your system without having to search through the whole manual to find or call tech support and take more time out of your day. We provide our technology to help make your lives easier, not more confusing. This is the one of multiple FAQ articles that will help you understand the basics of your devices.

How to Connect Cameras to an NVR

Written By:

NVR

Here at Security Camera King we have a variety of surveillance products that can help protect a home or business from crime. The products range from DVRs and NVRs to all the connectors that are needed to connect the cameras to the systems. Setting up a surveillance system DVR, which includes Analog, HD-CVI, and HD-SDI, tends to be easier to put together. When it comes to NVRs, they are working through a network and can be difficult if you don’t know what your doing. The biggest tough spots for this system are when connecting the system to your network, connecting your cameras to your network, and adjusting the frames and resolution of all the cameras to manage bandwidth and NVR load. IP camera systems are very advanced systems and if done properly can give the highest resolution in the industry.

Setting up an NVR has many steps before it can function properly. First things first is running cable for where you want cameras. Next is mounting cameras on a building or anywhere needed. After you have all of that done you can now properly connect your NVR to your network. You need to power up the NVR with the provided power supply and attach any necessary cable such as mouse for controlling the NVR’s interface, Power cable for built-in POE, Monitor for viewing the NVR’s interface, and lastly an ethernet cable that leads back to your router or a switch connected to your network. Now depending on how you want to manage your camera whether you want it on its own network or connected to your existing one there are different ways of accomplishing your goal. Setting up the NVR for earthier style is the same you need to assign a static IP address to your NVR so that you access it locally and remotely. The way to do this is by going to the “Main Menu” on the NVR (When doing this you will be prompted for username and password which is “888888” for both), then you need to go to “Settings”, and; “Network”. This is where you enter the IP for the NVR. By default the IP should be “192.168.1.108” and the “DHCP” should be unchecked. Now you can enter an IP address, Subnet, and Gateway of your network so that it has it’s own individual address on your network. This is all you have to do to set your NVR to your network and the next step is to start connecting your cameras to your network.

With the cameras mounted and the cable running to the destination of your choice either by your NVR or a spot in the attic/roof where your switch will be you can now start connecting your cameras to your network. Before you just plug all the cameras in at once you need to know what you want to plug them into. If you are just plugging them all into the POE built-in to the NVR then you can just plug in the cameras one by one till they show up on the NVR’s interface. This is the easiest way to connect cameras because as you plug them in, the NVR self-assigns an IP address to each camera. (This is only possible with our NVR’s and the EL Model Camera). Also when connecting your cameras this way makes the cameras only manageable by the NVR. If you are connecting your cameras to a separate switch then it requires a little more work. You have to connect the cameras in one by one just like before but before you connect another one you have to change the address for the camera. You can do this 1 of 2 ways, you can change it thought the NVR (This is only possible with our NVR’s and the EL Model Camera) or you can change it on the web interface built into the camera. The easy way is to just change it with the NVR. The way to accomplish this is after the camera and the NVR are connected to the switch, you search for the camera in the “Remote Device” section from the “Main Menu” and click edit next to the camera on the network. (Default is 192.168.1.108). After that is complete just repeat with every camera you want to connect. You can also adjust your color settings in this menu so that you don’t have to login to each camera and set it to the way you want. This can come in handy when you have a lot of cameras to manage. This is the process to connect your cameras to an NVR.

Now that the cameras are connected you need to adjust some settings on them to achieve maximum power out of you NVR. All the NVRs we sell have a certain number of frames or max bandwidth that it can handle. It’s important you know what the amount is because not all of them are the same. Once you figured out what the limit is you can adjust your cameras. To do so you need to go to the “Main Menu” on the NVR, “Settings”, and “Encode”. Here you can select the camera you want and adjust the frames and the resolution you want it to record at. You may also want to adjust the “Bit Rate” but you need to know what your doing or you can diminish your video quality. To copy this to other cameras in your NVR just adjust one camera the way you want and then click “Copy” and choose which cameras you want to copy the settings to. Under the same “Settings” menu you can adjust the schedule of when your camera records and if you want it to record 24/7, motion, alarm, or all three.

Compared to DVR’s, NVR’s are more difficult to set up. Setting up the IP for the NVR so that the NVR can be accessed locally and remotely. Connecting all the cameras to the NVR one by one assigning IP address to each camera. Lastly adjusting the cameras and NVR to get the most performance out of your NVR’s. Knowing these steps will make it easier to add an NVR for your surveillance needs

Network Security Camera

Written By:
Thursday, August 2nd, 2012

Although property crime statistics in the United States are steadily declining, according to Federal Bureau of Investigation, there is still a great need to safeguard your property. Whether you’re interested in adding security to your home or business, network security cameras continually monitor your property. While homeowners may feel security cameras are specifically made for businesses, by visually monitoring your home you not only ward off potential crimes by the sheer presence of the camera, but in the unfortunate event of theft or burglary the videos may help law enforcement identify and capture the thieves. Although there are a wide array of security cameras on the market, few offer the security and flexibility as network security cameras. If you’re in the market for security cameras, you should consider installing these items not only for their reliability, but also for the peace of mind their presence provides.

What is a Network Security Camera?

  • Network security cameras, also referred to as IP cameras, have the foundational purpose of traditional CCTV, or analogue, cameras; however, their method of sending and receiving data is much different. In a foundational sense, network cameras are quite similar to webcam as network cameras utilize the Internet to transmit and store recorded images. However, the similarities between webcams and network cameras end there. Network cameras are separated by two primary categories: centralized and decentralized cameras. The following are the two primary differences between these two camera setups:
  • Centralized Network Camera – A centralized network camera is one that requires a central NVR, or Network Video Recorder, to manage incoming recordings, video storage and alarm sounding if the cameras are attached to an audio alarm system. Commonly mistaken for a DVR, an NVR is a software program designed to record and store video from a network camera in a digital format. These digital videos are then saved to some form of digital mass storage such as a USB flash drive or an SD memory card. Although an NVR is solely software, the actual software is typically stored on a dedicated device that connects to various network cameras. The primary difference between an NVR and a DVR is an NVR receives its incoming video signals from an Internet network while a DVR receives its video signals from a direct connection to the camera. Another distinct difference between these software programs is how videos are processed and encoded. DVRs process and encode videos after they are streamed to the unit while NVRs process and encode video signals before being sent to the recording device.
  • Decentralized Network Cameras – A decentralized network camera is one that does not use an NVR. Rather, these cameras feature built-in video storage capabilities such as hard disk drives or flash drives. This form of storage is more streamlined, but features limitations such as not being able to store large quantities of data.
  • Types of Network CamerasNetwork security cameras are available in a wide array of formats and designs. However, while there are many designs there are seven primary camera types. Manufacturers may alter the features within these camera types; however, every network security camera is based in one of the following.
  • Outdoor Cameras – Designed specifically to be used outdoors, these network cameras feature weatherproof casings, significant temperature operation range, day and night recording as well as a tampering alarm. Typically used to monitor parking lots, campuses and traffic conditions, an outdoor network camera is ideal for areas that require 24/7 monitoring in all weather conditions.
  • Thermal Network Cameras – During moments of complete darkness, thermal network cameras are able to clearly capture images based on heat radiating from objects. All objects radiate a certain amount of heat, and this camera type is designed to capture the details from a heat source. The primary benefit of this camera design is its able to monitor property in complete darkness. Therefore, there’s no infrared LED lights illuminating the area. In complete darkness, onlookers are unaware they are being monitored. The downside of this camera design is its lack of detailing. While figures are clearly seen, small details typically captured by infrared security cameras are lost.
  • Megapixel Network Cameras – These cameras are designed to capture highly detailed images. Designed with the latest in high resolution surveillance technologies, megapixel network cameras, also referred to as HDTV cameras, can clearly record facial features or items a customer purchases.
  • Covert Cameras – As its name suggests, covert cameras are designed to seamlessly blend into its environment. Thus, onlookers are unaware of its presence while it continually captures their facial details and their actions. These cameras are ideal for monitoring customers in areas of a store that are unseen by wall or ceiling security cameras.
  • PTZ Dome Network Cameras – PTZ dome network cameras are designed to discreetly monitor a wide angle area. These cameras are housed in a dome, thus onlookers are unaware if the camera is pointing at them or not. The camera operator may manually tilt, zoom and pan while capturing high-quality video. Features typically found in these cameras include EIS, or electronic image stabilization, auto tracking and auto camera flip.
  • Fixed Dome Network Cameras – Like its name suggests, a fixed dome network camera does not offer lens movement. Rather, it is a fixed camera housed in a dome. The primary benefit of this camera design is its discreet design; however, the main drawback is its inability to interchange its lens. However, many fixed dome cameras offer a varifocal lens, which allows the field of view to be manually changed by an operator.
  • Fixed Network Camera – This camera design is perhaps the most common. Implemented to be visible to onlookers, a fixed camera cannot pan or rotate as its field of view is static. However, many fixed network cameras allow operators to change its lens. For example, a single fixed camera may be adjusted to house a wide-angle, telephoto or normal lens. Some camera designs are outfitted with a varifocal lens to adjust its field of view.

 

As stated earlier, these are simply the most common foundational designs. Each of the aforementioned is available in a wide array of configurations. To determine the best network security camera for your property, research available options and features. Remember, every property features unique monitoring challenges and the goal of a security camera system is to overcome these challenges for adequate monitoring.

Analog Resolution vs. Network Camera Resolution

Many property owners who are interested in security camera systems desire to have cameras with high video resolutions. The reason behind this is the higher the resolution the better the image quality. Cameras with low screen resolutions may capture the happenings of an area, yet if the images are blurry or fuzzy, these cameras do little to actually assist law enforcement in the apprehension of a criminal. Within the realm of security cameras, a major question is, “What is the resolution difference between traditional analog cameras and network cameras?” The recordable resolution of security cameras is dependent on the restrictions of the actual recording device such as a DVR for analog cameras or NVR for network cameras. With analog cameras, the DVR is restricted to a maximum resolution of 720 x 480 pixels. However, network cameras offer a wide array of resolutions. For example, many NVR programs support 5 megapixel, or higher, screen resolutions. This results in a video resolution of 2,592 x 1,944 pixels. Therefore, if image quality is paramount in your decision making process, network security cameras are your only option. Review various NVR programs, as some software programs may feature resolution limitations.

Benefits and Drawbacks of Network Security Cameras

As with any other form of security cameras, network security cameras feature benefits and drawbacks. Before making a purchasing decision, it is imperative you review the benefits and drawbacks to determine if the financial commitment of network cameras is worth the benefits you’ll receive.

Benefits

  • Installation Flexibility – Perhaps the most notable benefit of network cameras is its installation flexibility. Unlike analog security cameras, network cameras are able to be installed anywhere on a property where there is an IP network. This is not limited to Ethernet cable only networks. Many network cameras are able to operate and transmit signals through a wireless Internet signal.
  • Encryption – Securing the images of a camera is just as important as having a security system in your business or home. Network security cameras offer two layers of data safeguarding. Firstly, video images are encrypted before ever being transmitted to the NVR. Secondly, videos are automatically encrypted and authenticated through encryption languages such as WEP, AES, WPA and TKIP.
  • Video Resolution – As discussed earlier, network cameras offer significantly higher video resolution when compared to analog cameras. This increase in resolution provides clearer videos capable of identifying facial features and car license plates.
  • PoE Connectivity – Network security cameras do not need to be plugged directly into a power source. Rather, these cameras may operate by connecting the camera to a PoE, or Power over Ethernet, protocol. This system powers the cameras trough the Ethernet cable instead of through a traditional power source.

Disadvantages

  • Cost – If cost is an issue, then network security cameras may not be the ideal surveillance solution for you. Typically, network cameras require a higher upfront cost than analog security cameras. However, this disadvantage may quickly disappear as the use of network cameras increases. The increase in demand will likely lower the cost of these camera systems.
  • Video Interception – Although not very common, video signals may be intercepted if network cameras are connected through an unsecured wireless network. This raises the security threat as criminals could potentially access video streams and monitor the security environment of a business or home. This undermines the effectiveness of the cameras and actually facilitates a crime. Avoid this scenario by never connecting network cameras through a public, or unsecured, wireless signal.

While it may seem that the benefits of network security cameras far outweigh its drawbacks, it is important potential buyers seriously weight both the pros and cons before making a decision.
