Closed-circuit video, or video surveillance room camera supraveghere video, is an application of closed circuit television, which also called closed-circuit video, to send a video signal to a certain location, on a restricted set of monitors. These cameras can either be fixed or portable. Fixed cameras are placed in strategic positions to cover a large area. Portable video surveillance cameras can be staked to any flat surface.
If you want to use video surveillance camera systems, you need to determine the total area to be covered and the total storage space required. The measurement of space occupied by the cameras depends on the number of cameras required for optimum surveillance. You should also take into account the bandwidth requirement. Bandwidth is defined as the amount of data sent per unit of time. The larger the bandwidth requirement, the faster the transfer rate of data.
Surveillance cameras can be used to monitor public places such as government buildings, banks, airports, hospitals, schools and other institutions of public interest. It is also possible to install surveillance cameras to monitor private property such as homes, business premises and vehicles. For many of these public places, sufficient security measures can be installed, without necessarily affecting the functioning of the institution.
There are two types of surveillance cameras, namely closed circuit video cameras and transceivers. The closed circuit video cameras record the motion picture using a closed circuit transmitter. On the other hand, the transceiver uses radio frequency to send the captured motion picture to the receiver. Both of them provide high-quality video recording. However, the closed circuit system is more widely used in urban areas because of its easy installation and its low cost.
A closed-circuit television is basically a computer system that shows live images on a TV screen. This type of surveillance cameras is widely used in theaters and hotel lobby to monitor the movement of visitors and tenants. Closed-circuit video cameras are also very popular in airports to keep an eye on the behavior of suspected illegal aliens. In addition, closed-circuit video cameras are also used in traffic enforcement to control the traffic on highways. In such systems, a monitor is placed in front of the vehicle to monitor the traffic.
Video surveillance cameras use a relatively new technology called night vision cameras. This technology refers to the ability to view images in low light situations. As it is well known, the natural lighting at night is better than the artificial light during daytime. Thus, it is possible to obtain good images with night-vision cameras by adjusting the focusing power and the sensitivity of the image sensors. Besides, the night vision cameras should also have a high level of signal interference resistance.
Video surveillance cameras help prevent crime in many ways. For instance, as it is well known, criminals avoid areas where they know they will not be detected. Surveillance cameras help to prevent crime because they catch the criminal in the act and prevent him or her from escaping to save money. They help to apprehend criminals who commit crimes in public places. By preventing crime, the police will have less manpower to deploy to the various locations in and around the city where crime usually occurs.
Video surveillance cameras and facial recognition software go hand in hand. While the facial recognition software can sometimes be more successful in locating and catching criminals, the video footage of crimes can sometimes be difficult to identify. To solve this problem, CCTV cameras and facial recognition software are being put to use in a variety of public places such as banks, bus stations, schools, hospitals, government offices, shopping malls, etc. By using both of these technologies, criminals can easily be identified and caught in the act.
