APPENDIX A: TROUBLESHOOTING
Q
9. Why can’t I remotely log into the NVR client?
A
Please verify that the network connection settings are good and the RJ-45 port cable is securely connected. Also, be certain
that your username and password are entered correctly.
Q
10. Why can’t I find any records during playback?
A
Please check the data and power cable connections to the HDD are OK and that the system time is set properly. If it still doesn’t
work, run internal diagnostics on the HDD to be sure it is functioning OK.
Q
11. Why can’t the NVR control a PTZ camera?
A
Please check if:
a. Protocol of PTZ decoder does not match that of NVR.
b. Address of PTZ decoder does not match that of NVR.
c. PTZ settings in the NVR are not correct.
d. Connection and installation of PTZ decoder are not correct.
e. PTZ interface is malfunctioning.
f. If many decoders are connected to an RS485 network, the farthest end of the AB line should be terminated at the PTZ
decoder with a 120 Ω resistor to suppress reflections and match impedance. Otherwise, PTZ control may be unstable.
Q
12. Why doesn’t dynamic detection work?
A
Please check if the motion detection time and motion detection regional settings are correct. Verify that the sensitivity is not
set too low.
Q
13. Why doesn’t alarm work?
A
Please check if the alarm setting, alarm connection and alarm input signals are correct.
Q
14. Why does buzzer keep sounding?
A
Please check the alarm setting. Check to see if the motion detection buzzer is enabled and motion is detected all the time.
Verify that the I/O alarm is set as Always Off. Refer to the corresponding HDD alarm settings.
Q
15. Why can’t I stop recording by pressing the “STOP” button or click “Stop Recording” in
context menu?
A
Pressing Stop or Stop Recording only stops manual record. If you want to stop Scheduled recording at certain times, change the
setting to No Record. To stop Startup recording, change record mode to scheduled recording or manual recording. Then you
may stop recording by the prescribed methods. Another way of stopping recording is to set the channel to OFF status in record
setting.
