10.1 Troubleshooting
1. Q: What can I do if the system does not detect the HDD?
A:
Check if the power supply system is properly connected and data & power ports of HDD are
securely connected to motherboard, and if something wrong with the HDD interface. Or you may
check if your HDD is supported by referring to the specifications or descriptions.
2. Q: I have changed the password but forget the new password, how can I access the system?
A:
If you forget system password, please consult with our technical personnel. We strongly suggest
user to set password easy to be remembered and relatively safe. If you have safety requirement,
please do not set very simply password, such as 000000.
3. Q: We see abnormal video signal or even no video signal by connecting the NVR and camera
together. Power supply for both devices is OK. What is wrong?
A:
Check network cable at NVR side to see if the cable is firmly connected and if it is worn out and
needs to be replaced, or to check if NTSC or PAL is selected consistently.
4. Q: How to prevent NVR from being influenced by heat?
A:
The NVR needs to dissipate heat while it is running. Please place the NVR in a place with good
air circulation and away from heat sources to ensure stability and life of the NVR.
5. Q: The remote controller of NVR doesn’t work while the monitor screen is OK and panel keys
are functional. Why?
A:
Operate again by aiming the remote controller at the IR receiver on front panel. If it still doesn’t
work, please check if the batteries in the remote controller are dying. If not, check if the remote
controller is broken.
6. Q: I want to take out HDD from my PC and install it in NVR. Can it work?
A:
All HDDs supported by the system can be used. But remember, once NVR runs, the data on your
HDD will be lost.
7. Q: Can I playback while recording?
A:
Yes. The system supports the function of playing while recording.
8. Q: Can I clear some records on HDD of NVR?
A:
In consideration of the file security, you may not clear part of records. If you want to remove all
the records, you can format HDD.
9. Q: Why can’t I log in NVR client?
A:
Please check if the network connection settings are correct and RJ-45 port is with good contact.
And check if your account and password are correctly input.
10. Q: Why can’t I find any records during playback?
A:
Please check if the data port connection for HDD is OK and system time is properly adjusted.
Try a few times and restart. If it still doesn’t work, check if the HDD is broken.
11. Q: Why doesn’t dynamic detection work?
A:
Please check if the motion detection time and motion detection regional setting are correct and
if the sensitivity is set too low.
12. Q: Why does buzzer keep alarming?

Please check the alarm setting, check if motion detection function is enabled and object motion
is detected all the time. Besides, refer to corresponding HDD alarm setting.
