CCTV, stands for close circuit television, often becomes a choice for people to monitor activities in a room or building. Mostly, it is installed in department store to monitor the visitors so they can prevent any thief to steal anything from their racks. Besides, this system also might be installed in school and office to monitor the behavior of students and employee. Whatever the purpose of the installation, people tend to thing that this system could be a total guarantee for their security level. Unfortunately, this opinion is wrong since CCTV camera also has some disadvantages as well.
Let us talk about the advantages first. For some places like department stores or banks, CCTV is very useful to prevent crime risk such as burglary, robbery, or theft. By installing this system, people know that they are being monitored all the time by the operator. Therefore, the risk of criminal act tends to be reduced. Moreover, this system also will be helpful to monitor customer service employees. Some customers might be very annoying, and physical violation is quite risky to happen. By installing CCTV, this risk could also be reduced.
However, you should not think that CCTV is a perfect system to provide security. CCTV does not always works in proper system. It could not display every single square of your office, banks, stores, and other areas. Although you set the location of the system in a very careful way, you still cannot get total guarantee of security level. Why?
There are a lot of factors that makes CCTV is not a 100% trustful security device. People that are familiar with the certain area might sabotage the system by sticking a piece of chewing gum on the lenses or doing some changes to the cable system. Even some professional could also change the angle of the camera, so the criminal target area will not be displayed to the operator.
There will always be any advantages and disadvantages for every single security system, including CCTV system. Your careful thought is the main determination of the security level in your store or office.
