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.

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.

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.
