How surveillance cameras work
The principle of surveillance cameras is to capture a video of a place, and then through the central cameras that are connected to it, send snapshots to a screen that displays what the cameras are filming. Unlike traditional television broadcasting, CCTV sends a closed signal to the receiver; This allows the scenes to be accurately monitored through connected devices only. Surveillance cameras are also considered to have a wide ability to shoot for a wide range, so placing them in a corner area of ​​the room will enable them to capture a large part of the room without obstruction, in addition to the quality of the images is very large due to receiving screens Video in high resolution from the eye of the surveillance camera, and a VCR television recording device can be connected to surveillance cameras in order to record images and scenes sent for future reference, and surveillance cameras are linked to other devices by a coaxial cable, but modern systems have incorporated wireless technology in order to connect devices together and to stop the use of wires.

Communication and power source in CCTV
The majority of surveillance cameras or security cameras operate on a Wi-Fi network, meaning that they need to be properly placed within the bandwidth or wireless access point in the home, and a Wi-Fi signal interruption will keep the camera turned on, and most cameras are powered by a connecting adapter , but this does not mean that the camera cannot be moved from one place to another; Rather, the location of the exit must be considered when determining the installation area of ​​the camera, or an extension cord can be kept on hand, and some cameras operate on a system of replaceable, replaceable, and rechargeable batteries.

Types of surveillance cameras
Among the types of cameras that are used for surveillance:

Large cameras: These are visible cameras that are installed outside or in an area known to be under video surveillance.
Hidden cameras: They are small cameras that are used unobtrusively for the purpose of surveillance, but legal restrictions on video surveillance must be noted before installing this type of cameras.

Wireless cameras: These cameras are flexible, but streaming from other devices such as wireless internet and phones may cut off the wireless camera signal.
