Camera classification and characteristics?

The cameras are roughly divided into the following categories according to their functions: shotguns, hemispherical cameras, integrated cameras, infrared day and night cameras, high-speed dome cameras, and network cameras.

1. Shotgun: The price is cheap, but it does not have zoom and rotation functions, and it can only complete the monitoring at a fixed angle and the concealment is poor;
2. Hemispherical camera: it has a certain concealment *, at the same time, it is compact and beautiful, and can be mounted on the ceiling, making up for some of the deficiencies of the gun machine;
3. All-in-one camera: built-in lens, automatic focusing, convenient lens control, simple installation and debugging;
4. Infrared day and night camera: the camera, protective cover, infrared lamp, power supply and heat dissipation unit are integrated into one camera device, which has the advantages of long night vision distance, strong concealment and stable performance;
5. High-speed dome camera: a device that integrates an all-in-one machine camera and a pan-tilt in one, and has the characteristics and functions of fast tracking, 360 ° horizontal rotation, no surveillance blind area and privacy area shielding;
6. Network camera: also known as IP camera. It can digitally process and compress the image after it is collected, and send the compressed video signal to the server or client side through the IP network; on the server or client side, the remote image can be viewed in real time through the software.
