1. Point to point independent power supply mode

Point to point independent power supply means that 220V AC is directly led out from the security monitoring room, and wires / combination wires (network cables + wires) are used in the middle, and then a separate DC12 / 24V power adapter is connected next to the camera, and then connected to the monitoring camera. Each power supply only provides power for one camera head.

2. Centralized power supply mode

Centralized power supply refers to connecting a 12 / 24v4a centralized power supply at the 220V power supply, and then connecting it to the camera with 2 * 1.0 red and black power line / combination line respectively. There is no need to install another power adapter at the front end of the camera. Compared with the point-to-point independent power supply mode, the biggest difference of this mode is that one power supply can supply power to multiple cameras.

3. Poe network cable power supply mode
Poe network cable power supply refers to a mode that can not only supply power to the front-end network camera but also transmit data through a network cable without any change to the existing Ethernet wiring architecture, commonly known as network cable power supply. two
