5. Check if the fault is solved by the above steps. If it is solved, finish the process. If not, contact a
Hikvision engineer for further processing.
Image Freezes when Device Plays Single or Multi-Channel
Possible Reasons:
•
Poor network connection between device and IP camera, and there is packet loss during transmission.
•
The frame rate is not the real-time frame rate.
•
The device supports up to 16-channel synchronized playback at 4CIF resolution. For 16-channel
synchronized playback at 720p resolution, frame extracting may occur, which leads to slight stuttering.
1. Verify the network between the device and the IP camera is connected.
1) When image freezes, connect the RS-232 ports on the PC to the rear panel of the device with an RS-
232 cable.
2) 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 is packet loss.
Simultaneously press Ctrl and C to exit the ping command.
2. Verify the frame rate is real-time frame rate.
1) Select Menu > Record > Parameters > Record, and set the Frame Rate to “Full Frame.”
3. Verify the hardware can afford the playback. Reduce the playback channel’s settings.
1) Go to Menu > Camera > Encoding Parameters, and set the resolution and bitrate to a lower level.
4. Reduce the number of local playback channels.
• Go to Menu > Playback, and uncheck the checkbox(es) of unnecessary channels.
5. Check if the fault is solved by the above steps. If it is solved, finish the process. If not, contact a
Hikvision engineer for further processing.
