Steps
1.
Verify the cable between the pickup and IP camera is connected well; impedance matches and is
compatible.
2.
Log into the IP camera directly, and turn the audio on. Check if the sound is normal. If not, contact the IP
camera manufacturer.
3.
Verify the setting parameters are correct.
4.
Select “Menu > Record > Parameters > Record”, and set the Stream Type to “Audio & Video.”
5.
Verify the NVR supports the IP camera audio encoding standard.
6.
NVR supports G722.1 and G711 standards, and if the encoding parameter of the input audio is not one of
these standards, log in the IP camera to configure it to the supported standard.
7.
Check if the fault is solved by the above steps.
1)
If it is solved, finish the process.
2)
If not, contact Hikvision tech support for further help.
•
The image freezes when the NVR plays back single or multi-channel.
Possible Reasons
-
Poor network between NVR and IP camera, and there exists packet loss during the transmission.
-
The frame rate is not the real-time frame rate.
-
The NVR supports up to 16-channel synchronize playback at 4CIF resolution. For 16-channel synchronized
playback at 720p resolution, frame extracting may occur, which leads to image freezing.
Steps
1.
Verify the network between NVR and IP camera is connected.
1)
When image is frozen, connect the RS-232 ports on a PC and the rear panel of NVR with a 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 exists packet loss.
NOTE:
Simultaneously press the Ctrl and C to exit the ping command.
2.
Verify the frame rate is real-time frame rate.
3.
Select “Menu > Record > Parameters > Record”, and set the Frame Rate to “Full Frame.”
