The image gets stuck when NVR is playing back by single or multi-channel.
Possible Reasons:
a) Poor network between NVR and IP camera, and there exists packet loss during the transmission.
b) The frame rate is not the real-time frame rate.
c) The NVR supports up to 16-channel synchronize playback at the resolution of 4CIF, if you want a
16-channel synchronize playback at the resolution of 720p, the frame extracting may occur, which leads to
a slight stuck.

3) Enter the destination address in the text field of Destination Address.
4) Click Test button to start testing network delay and packet loss. The testing result pops up on the
window.
If there exists return information and the time value is little, the network is normal.
