How surveillance cameras work
The principle of the work of surveillance cameras is based on capturing a video of a place, and then through the central cameras to which they are connected, sending footage to a screen that displays what the cameras are shooting, and unlike traditional television broadcasting, CCTV transmits a closed signal to the receiver; which allows the viewer to be accurately monitored via only connected devices, and surveillance cameras In addition, the quality of the images is very large due to the monitors receiving video in high resolution from the eye of the surveillance camera, and a VCR TV recorder can be connected to the surveillance cameras in order to record the images and scenes sent for future reference Surveillance cameras are also connected to other devices by a coaxial cable, but modern systems have integrated wireless technology in order to connect devices together and to stop the use of wires
Connection and power supply of surveillance cameras
The majority of surveillance cameras or security cameras work on a Wi-Fi network, which means that they need to be placed in the Wave range or wireless access point at home correctly, and the interruption of the Wi-Fi signal will keep the camera turned on, and most cameras are powered by a plug adapter, but this does not mean that the camera cannot be moved The location of the outlet should be considered when determining the camera installation area, or an extension cord can be kept at hand, and some cameras also work on a system of replaceable, changeable and rechargeable batteries.
Types of surveillance cameras
Types of cameras that are used for surveillance:
Large cameras: these are visual cameras that are installed outside or in an area known to be subject to video surveillance.
Hidden cameras: these are small cameras that are used covertly for the purpose of surveillance, but the legal restrictions on video surveillance must be observed before installing this type of camera.
Wireless cameras: these cameras have flexibility, but broadcasting from other devices such as wireless internet and telephones may cause the wireless camera signal to be cut off.
