PoE cameras cannot be powered on by PoE Switch/Injector
The camera cannot be powered on while using PoE Switch or PoE injector. Please reset the camera and cover the daylight sensor on the camera lens or take the camera to a dark room and wait for a few seconds then you'll find the IR lights on the camera will not light up/not hear a "click" sound.
Cause 1. Incompatible PoE switch/injector
Solution: Please refer to Which POE injector/switch can I use for Reolink POE cameras
Cause 2. The camera is not properly connected to the PoE switch/injector
Solution: Please check the lights on the PoE switch/injector. If the lights are not on, please try to plug the camera into other ports that work and use another working Ethernet cable.
Cause 3. The PoE module of the camera fails to get power
Solution: Please use the DC adaptor to power the camera on.
For more information, please check POE Cameras Cannot Be Powered on by POE Switch/POE Injector.
Fail to add PoE camera to NVR
After plugging the new camera to the NVR, the camera's image does not show up on the monitor and it prompts "video loss". The following troubleshooting may be helpful to you.
Cause 1. No available channels can be distributed to the new camera
Solution: In this case, you have to remove the cameras which are no longer used and then manually distribute a channel to the new camera. You can refer to How to Delete Camera from PoE NVR//How to Delete Offline Camera Information on Channel Management Page via Reolink NVR(New UI)
Cause 2. The new camera has been distributed with the same IP address as the previously added cameras
Solution: Generally, this situation will cause more than one camera to be offline, or video loss. On the IP channel page, there will be at least two cameras with the same IP address. In this case, please reset the PoE camera, and you can refer to How to Reset Bullet or Dome Cameras. Also please reboot the NVR.
Cause 3. It shows "invalid PWD" on the IP channel page/live view page
Solution: It means that the camera has been set with a password previously, so the NVR couldn't recognize its password. Please input the camera's password to add it.
