The image gets stuck when the DVR is playing back by single or multi-channel.
Possible Reasons:
Poor network between DVR and IP camera, and there exists packet loss during the transmission.
•
The frame rate is not the real-time frame rate.
•
The DVR supports up to 16-channel synchronize playback at 4CIF resolution. If you want 16-channel
•
synchronized playback at 720p resolution, frame extracting may occur, which leads to slight sticking.
Verify the network between DVR and IP camera is connected.
When image is stuck, connect the RS-232 ports on PC and the rear panel of DVR with the RS-232 cable.
Open the Super Terminal, and execute the command of "ping 192.168.0.0 –l 1472 –f" (the IP address may
change according to the real condition), and check if there exists packet loss.
