The Disadvantages of CCTV Cameras

Closed-circuit TV cameras supposed to catch violent thugs have been trained on roads instead - to trap and fine motorists who stray into bus lanes.

The most common home security system used is a CCTV system. CCTV stands for Closed circuit television. It is considered a revolutionary invention when it comes to security. Due to it’s advantages it gained fame in no time. It is often used for security purposes in house, stores and banks etc. It keeps an eye on the visitors. It can also be used in schools to track the behavior of a student. It has countless advantages, but that does not mean that it is perfect. Yes! CCTV has its disadvantages as well. In this article we are going to discuss the disadvantages of CCTV camera.

CCTV is not always a perfect working system for security. It does not keep an eye on every corner of your office, house or mall. It can just keep an eye on a limited area. It can be easily sabotage by sticking a gum or spraying something on the lens or cutting the cables.

Usually a CCTV is installed at a spot where humans can not reach but criminals usually can easily view CCTVs position and can possibly change the angle so the camera do not catches the crime scene. CCTV cameras can view what normal people are doing this effect the people in a bad way as there is no privacy left. This is a great disadvantage of CCTV cameras.

But wireless bullet camera is such a technology that has improved security of malls, houses and offices. In some cases the camera may miss the detail of the crime scene. For example a concealed weapon the camera is unable to view it in the first place.

The video of a CCTV can be hacked by a hacker easily. Suppose there is a CCTV installed near an ATM machine. So the hacker will hack the video of that camera and can easily get the pin code and any other information he wants about a customer or ATM user.

Another disadvantage of CCTV is that not everyone can afford it. Despite all these disadvantages CCTV still allows you to secure your place to a great deal. It has disadvantages but as you know nothing is perfect.

The following are some of the potential weaknesses of IP cameras in comparison to other CCTV cameras.
Disadvantages are that they are costly, do not always work (as they are not set up in the right places) and manipulate with people's privacy.

1. Higher initial cost per camera.

2. Fewer choices of manufacturers.

3. Lack of standards. Different IP cameras may encode video differently or use a different programming interface. This means a particular camera model should be deployed only with compatible IP video recording solutions.

4. Technical barrier. Installation for IP camera required a series of complicated network setting including IP address, DDNS, router setting and port forwarding. This is very difficult for most users to do without help from an IT technician.

5. Lower dynamic range - i.e. reduced ability to cope with low light and high contrast scenes.

HDCCTV has the following disadvantages:

1. Closed technology – little room for improvement in picture quality going forward.

2. Limited maximum resolution of 1.8 mega pixels (1080 TV lines)

3. Currently difficult and expensive to transmit HD images over CAT5e network cables.

4. Dumb cameras – only the DVR is addressable over the network or the web
