How surveillance cameras work
The working principle of surveillance cameras is based on capturing a video of a place, and then through the central cameras that are connected to it, sending snapshots to a screen that displays what the cameras depict, and unlike traditional television broadcasts, closed circuit television sends a closed signal to the receiver; This allows scenes to be accurately monitored through connected devices only, and surveillance cameras 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 hindrance, in addition to that the quality of the images is very large due to receiving screens The video is in high definition from the eye of the surveillance camera, and a VCR can be connected to the surveillance cameras in order to record images and scenes sent for future reference, and the surveillance cameras are linked to other devices by a coaxial cable, but modern systems have incorporated wireless technology in order to connect the devices With some and to stop using wires.

Connection and power source in surveillance cameras
Most surveillance cameras or security cameras work on a Wi-Fi network, which means that they need to be properly placed within the bandwidth or wireless access point in the house, and interrupting the Wi-Fi signal will keep the camera running, and most cameras are powered by an adapter , but this does not mean that the camera cannot be moved from one place to another; Rather consider the location of the outlet 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
Large cameras: These are the 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 hidden for the purpose of surveillance, but legal restrictions on video surveillance must be noted before installing this type of camera.
Wireless Cameras: These cameras are flexible, but streaming from other devices such as wireless internet and phones may cause the camera's wireless signal to break.
