Home surveillance camera
The gun is a kind of camera, which is different from the gimbal. Generally, the gun cannot be controlled remotely. Once V is set, the remote control cannot be performed through the keyboard remote control. At present, the more advanced are infrared guns and pressure transmitters, that is, a circle of infrared lights is installed near the camera, so that video can be recorded even in the dark.
The monitor is the standard output of the monitoring system. With the monitor we can view the images sent from the front end. The monitor is divided into color and black and white. The sizes are 9, 10, 12, 14, 15, 17, 21 inches, etc. The commonly used is 14 inches. The monitor also has a resolution of 111-11 cameras, which is expressed by the number of lines.
