Applies to: All NVR
There are 2 kinds of POE in the market.
One is standard POE which is using 802.3af or 802.3at(POE+). The voltage is 48V.
The other is sPOE which doesn't support 802.3af nor 802.3at. The voltage is 12V.
The above shows all the types of SANNCE POE systems.
If yours is standard POE, the maximum the length between camera and NVR can be 100M maximum with CAT5e or CAT6 cable. But due to local environment fluence, the distance may be less.
If yours is sPOE, the maximum distance between the camera and NVR can be 50M maximum if you use CAT5e or CAT6 cable. But due to local environment fluence, the distance may be less.
Only standard POE IPC can?be plugged?POE switch, but sPOE can't due to technical reasons.
Therefore, please check the system's model which is at the bottom of NVR.
If the model is POE type,?the cameras with that NVR can connect the POE switch.
If it is sPOE, the cameras with that NVR? can't and it must be plugged into the NVR directly.
