10 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 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 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: Is it possible to add IP camera with different protocols?
A: Yes it is. The HVR is able to recognize automatically the right protocol.
4.
Q: Is it possible to control AHD cameras through UTC or UTC-Z function?
A: Yes it is, An OSD is displayed pressing [Iris] or [Central Enter] buttons, the arrows key allow to navigate into
menu.
5.
Q: We see abnormal video signal or even no video signal by connecting the HVR and camera together. Power
supply for both devices is OK. What is wrong?
A: Check network cable at HVR 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.
6.
Q: How to prevent HVR from being influenced by heat?
A: The HVR needs to dissipate heat while it is running. Please place the HVR in a place with good air circulation and
away from heat sources to ensure stability and life of the HVR.
7.
Q: The remote controller of HVR 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.
8.
Q: I want to take out HDD from my PC and install it in HVR. Can it work?
A: All HDDs supported by the system can be used. But remember, once HVR 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.
10. Q: Can I clear some records on HDD of HVR?

13. Q: Why HVR cannot control PTZ?
A: Please check if:
1. PTZ in the front side is malfunctioned.
2. Setting, connection and installation of PTZ decoder are not correct.
3. PTZ setting of HVR is not correct.
4. Protocol of PTZ decoder does not match that of HVR.
5. Address of PTZ decoder does not match that of HVR.
6. If many decoders are connected, the farthest side of AB line of PTZ decoder should be added 120Ω resistance
to realize reflection suppression and impedance matching. Otherwise, PTZ control will be unstable.
14. 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.
