There are advanced and sophisticated technologies in the world of various video cameras. But we will touch on smart digital video cameras Smart digital video camera, which are used for surveillance. We all know the ordinary video cameras known as CCTV Camera, used-only-to record events and for surveillance in most government and private facilities.
Surveillance cameras are deployed in many places and facilities to prevent crimes, but there is still a need for a human element that analyzes the data of surveillance tapes. However, the creation of smart surveillance cameras will allow allocating a small number of employees to follow them, and will also allow expanding their use in public facilities.
A smart camera has many advantages. One of the most important is not to consume as much energy as is the case with CCTV cameras. It works only when there is a person, movement or sound. There are a number of sensors with different applications in it. There are sensors based on Rays, designed to detect the movement of objects , and then the camera begins to move towards the target, focus on it and follow it. When the target moves away from the camera range, it sends a signal to neighboring cameras to follow and locate the moving object. This type of network is called Smart Camera Networks, smart camera networks.
There is another type that relies on detecting sound and following its source, and this type of camera is fairly modern. It is designed in a way based on the principle of Voice Recognition to identify the source of different sounds. For example: if there is a shooting here, the camera knows that there is a shooting sound, and then it starts working, locating the sound and following it, and sending a signal to all cameras connected to the network, and from here the sound source is followed.
