I buy yesterday NVR model DH-NVR4108H-8P with 8 ports integrated switch and POE.
1.When i connect camera on one of the port camera note getting power(signal lan led is off) and when i cover led sensor on camera NIGHT LEDS not light red.After that i plug external power adapter 12V 1A and also connect camera to NVR with network cable,signal lan diode blinking green also when i cover light sensor on camera night LEDS light red.MY question is have any setting to active POE on NVR or going automatically.
