Check if the fault is solved using the steps above.If solved, finish the process.If not, contact engineer from our company for additional troubleshooting. The image freezes when the NVR is playing back on single or multi-channel.Possible Reasons: Poor network between NVR and IP camera and packet loss exists duringtransmission.

If you want a 16-channel synchronize playback at the 720p resolution,frame extracting may occur, leading to an occasional freeze.Corrective Actions:1. Verify the network between the NVR and IP camera is connected.a. When image is frozen, connect the RS-232 ports on the PC and the rear panel ofthe NVR with the RS-232 cable.b.
