Chapter 6 Appendix
6.1 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 along with the data cord
and power cable. Check 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 contact our technical support team for
assistance. These devices are specifically designed not to easily reset the password,
so 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: There is abnormal video signal or even no video signal by connecting the NVR and
camera together and power supply for both devices is okay. What is wrong?
A: Check network cable at NVR side to see if the cable is firmly connected. If it is worn
out it may need to be replaced.
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: Why doesn’t the remote controller doesn’t work whilst the monitor screen is okay
and panel keys are functional?
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 will it work?
A: All HDDs supported by the system can be used. But remember, once NVR
reformats the HDD, all previous 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. Otherwise, using overwrite mode will
begin to record over the oldest footage once the storage is full.
9. Q: Why can’t I log in NVR client?
A: Please check if the network connection settings are correct and RJ-45 / Ethernet
port connection is secure. Check if your account and password are input correctly.
