POE
POE ports: A POE port can transmit not only a network signal, it can also supply power for cameras.
The POE power supply standards of Dahua cameras that support POE power are mainly divided into two types:
- 802.3af (most)
- 802.at (few)
Category | 802.3af (PoE) | 802.3at (PoE plus) |
Classification | 0~3 | 0~4 |
maximum current | 350mA | 600mA |
PSE output voltage | 44~57V DC | 50~57V DC |
PSE output power | <= 15.4W | <= 30W |
PD input voltage | 36~57V DC | 42.5~57V DC |
PD maximum power | 12.95W | 25.5W |
Cabling requirements | Unstructured | CAT-5e or better |
- The NVR automatically assigns an IP to the POE connected camera
- The IP of the camera starts with 10.1.1.X (by default)
- The IP format of the camera can be changed in the NVR menu and cannot be changed to the same segment as the NVR
- If an IPC supports both DC12V power supply and POE power supply, the two power supplies can be connected at the same time. By default, DC12V power supply is used first. Switching from POE to DC12V is seamless, but switching from DC12V to POE requires power down
