8.1 Troubleshooting
1. Q: What can I do if the system does not detect the HDD?
A: Check if the power supply 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 forgot 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 a password that’s easily remembered and relatively safe. If you have any
safety requirements, please do not set a very simple password such as 000000.
3. Q: We see abnormal video signals or even no video signals when connecting the WIRELESS
NVR and camera together. Power supply for both devices is OK. What is wrong?
A: Check network cable at WIRELESS NVR side to see if the cable is firmly connected and if
it is worn out and needs to be replaced, or check if NTSC or PAL is selected consistently.
4. Q: How do I prevent my WIRELESS NVR from being influenced by heat?
A: The WIRELESS NVR needs to dissipate heat while it is running. Please place the
WIRELESS NVR in a place with good air circulation and away from heat sources to ensure
stability and life of the WIRELESS NVR.
5. Q: The remote control of the WIRELESS 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 control are dying. If not, check if the
remote control is broken.
6. Q: I want to take out HDD from my PC and install it in WIRELESS NVR. Can it work?
A: Only authorized personnel may replace a hard drive in a Speco technologies NVR, and
only authorized hard drives may be used.
7. Q: Can I playback while recording?
A: Yes. The system supports the function of playing while recording.
8. Q: Can I clear only some records on HDD of WIRELESS NVR and keep others?
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 into the WIRELESS NVR client?
A: Please check if the network connection settings are correct and RJ-45 port has good
contact. Also check if your account and password are input correctly.
10. Q: Why can’t I find any records during playback?
A: Please check if the data line connection for HDD is OK and system time is properly
adjusted. Try a few times and restart. If it still doesn’t work, check if the HDD is broken.
