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 cord and power
cables are securely connected, and if something wrong with the HDD interface. Or
you may check if your HDD is supported by referring to the specifications or
descriptions.

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.
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 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.

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.

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.

properly adjusted. Try a few times and restart. If it still doesn’t work, check if the
HDD is broken.
