- The image gets stuck when the NVR/DVR is playing back by single or multi-channel.
Possible Reasons:
a) Poor network connection between the NVR/DVR and the IP camera, and there exists a packet loss during the
transmission.
B) The frame rate is not the real-time frame rate.
C) The NVR/DVR supports up to 16-channel synchronised playback at the resolution of 4CIF, if you want a 16-
channel synchronised playback at the resolution of 720p, frame extracting may occur, which leads to a slight
stuck.
Steps:
1. Verify that the network between the NVR/DVR and the IP camera is connected.
1) When the image is stuck, connect the RS-232 ports on the PC and the rear panel of the NVR/DVR with the RS-
232 cable.
2) Open the Super Terminal Software, 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 a packet loss.
NOTE: Simultaneously press “Ctrl” and “C“ to exit the ping command.
2. Verify that the frame rate is the real-time frame rate.
Select “Menu> Record> Parameters> Record”, and set the Frame Rate to “Full Frame”.
3. Verify that the hardware can afford the playback. Reduce the channel number of the playback. Select “Menu>
Record> Encoding> Record”, and set the resolution and bitrate to a lower level.
4. Reduce the number of the local playback channels. Select “Menu> Playback”, and uncheck the checkboxes of
unnecessary channels.
5. Check if the fault is solved by the above steps. If it is solved, fi nish the process. If not, please contact your
system supplier for support.
