8. Troubleshooting
If you have problems with the system, run through the following checklist to see if you can solve
the problem.
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 power 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.
2. Q: I have changed the password but forget the new password, how can I access the system?
A: If you have configured the email settings, you can click "Forget Password" on the login window
and the system will send the password or a super password to the setup email address. If you have
never configured the email settings, please mail the MAC Address, Serial Number and the Model
Name to
ts@everfocus.com.tw
to get a temporary password.
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 control doesn't work while the monitor screen is OK and panel keys are
functional. Why?
A: Operate again by aiming the remote control at the IR receiver on front panel. If it still doesn't
work, please check if the batteries in the remote control are running out of power. If not, check if
the remote control 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 formatted.
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?
