How does the surveillance camera connect to the computer monitor?

First, there are nine buttons behind the camera, and the other end can be a shower head.

The monitor is VGA interface.

If you want to monitor the image on the monitor, the suggestion can be realized by using a TV box.

Connection mode:

The camera is connected to the shower head of the TV box, and the display is connected to the VGA interface of the TV box. Just set the remote control panel of the TV box as the shower head display screen.

The TV box is generally more than 100 yuan.

If the monitoring area is 60m *15m wide, it is recommended to use a gun camera with a larger lens.

Surveillance camera is a quasi-camera used for security. Its pixel and resolution are higher than computer video head, but lower than professional digital camera or dv. Most surveillance cameras are just a single video acquisition device, and there are few data storage functions. Surveillance cameras are mainly divided into gun type, hemispherical type and high-speed spherical type in appearance, and there are also differences between analog surveillance and IP network surveillance, which are widely used in many security fields such as banks, transportation and safe cities.

Mode of operation

The image of the object shot by the monitoring camera is focused on the CCD chip through the lens, and the CCD accumulates corresponding charges according to the intensity of light. Under the control of video sequence, the accumulated charge of each pixel is moved out point by point, and the video signal is output after filtering and amplification. When a video signal is connected to the video input of a monitor or TV, you can see the same video image as the original image.
