What's the difference between coaxial surveillance cameras and analog surveillance cameras? You don't need to know the definition, you need to know the wires used in the wiring method and so on.

Clarity: Coaxial monitoring can be said to be an upgraded version of ordinary analog monitoring, in order to let users of analog monitoring enjoy high-definition effect through upgrading. Coaxial cameras need to use coaxial HD video for recording, and network cameras need to use NVR for recording.

Connection mode: coaxial and analog are exactly the same, using video cable +BNC head; Of course, twisted pair transmission can also be used. Coaxial cameras are connected by analog wiring, that is, data cables, while network cameras are connected by network cables, with different wiring methods.

Line selection: Coaxial HD requires more video lines than ordinary analog monitoring. The remote monitoring of coaxial high-definition camera needs to be carried out through video recorder, and the network camera can be separated from video recorder for remote monitoring.

If you want to access the coaxial camera, the hard disk recorder must use the coaxial hard disk recorder. Coaxial hard disk video recorder can be connected with coaxial camera or ordinary analog camera.

Extended data:

The construction of coaxial high-definition camera is difficult, and the construction method is exactly the same as that of analog monitoring, which is more suitable for engineering transformation. Transmission equipment, analog and coaxial video cable, network cable; Retransmission distance, a network cable should not exceed 100 meters, coaxial video cable should be used well within 300 meters, and analog ordinary video cable can transmit 500 meters.
