transmission.
b) The motion detection and alarm functions
are enabled, and the parameters of Main
Stream (Normal) and Main Stream (Event)
are different. So the image looks stuck due
to the image changes between different
resolutions.
c) The frame rate is not the real-time frame
rate.
d) 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.
Steps:
1. Verify the network between NVR and IPC
is connected.
1) When image is stuck, connect the RS-232
ports on PC and the rear panel of NVR
with the 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. Check the parameters of Main Stream
(Normal) and Main Stream (Event).
Select “Menu > Record > Parameters >
Record”, and set the resolution of Main
Stream (Event) the same as the one of Main
Stream (Normal).
3. Verify the frame rate is real-time frame
rate.
Select “Menu > Record > Parameters >
Record”, and set the Frame Rate to “Full
Frame”.
4. Verify the hardware can afford the
playback.
Reduce the channel number of playback.
Select “Menu > Record > Encoding >
Record”, and set the resolution and bitrate to
a lower level.
5. Reduce the number of local playback
channel.
Select “Menu > Playback”, and uncheck the
checkbox of unnecessary channels.
6. Check if the fault is solved by the above
steps.
If it is solved, finish the process.
If not, please contact the engineer to do the
further process.
No record file found in the NVR local HDD,
and prompt “No record file found”.
Possible Reasons:
a) The time setting of system is incorrect.
b) The search condition is incorrect.
c) The HDD is error or not detected.
Steps:
1. Verify the system time setting is correct.
Select “Menu > Configuration > General >
General”, and verify the “Device Time” is
correct.
2. Verify the search condition is correct.
Select “Playback”, and verify the channel
and time are correct.
3. Verify the HDD status is normal.
Select “Menu > HDD > General” to view the
HDD status, and verify the HDD is detected
and can be read and written normally.
4. Check if the fault is solved by the above
steps.
If it is solved, finish the process.
If not, please contact the engineer to do the
further process.
