Milesight-Troubleshooting-PoE Power Supply of PoE NVRMilesight-Troubleshooting-PoE Power Supply of PoE NVR.pdf Note:
1. Usually the PoE NVR provides enough power for most network cameras connected via PoE ports except Mini PoE PTZ Bullet, Mini PoE PTZ Dome and Speed Dome.
2. If the cameras work normally in daytime but power off at night, it might be caused by the powered IR LED. Please take the above tables as reference which show the situations when cameras have the largest consumption.
3. You can check each camera's power consumption you apply and compare that with above Power Supply table for the power use of reference.
