8.3: Troubleshooting

Q: What can I do if the system does not detect the HDD?
A: Check the data and power cables and make sure they are securely connected.
Q: I have changed the password but do not remember the new password. How can I access the system?
A: If you forget the system password, enter 519070 into the password field to reset the password
Q: I am not getting any video signal on the DVR. What is wrong?
A: Check to make sure the cables are securely connected to the BNC ports on the DVR. You can also try another
cable to make sure there is not a problem with the cable. Make sure you have selected the correct video format for
your country (NTSC is standard USA format).
Q: Can the DVR have problems if it gets too hot? How can I prevent my system from over-heating?
A: The DVR has a fan to help it dissipate heat while it is working. Please place the DVR in a place where there is
good air circulation and away from high temperatures to increase the stability and product life of your DVR.
Q: My remote control does not work when the DVR is in Live mode but the front panel buttons are working. What is
wrong?
A: Make sure nothing is blocking the LED on the remote or the DVR. If both are ok, check the batteries of your
remote.
Q: Can I use the hard drive from my PC in the DVR?
A: You can if the hard drive is the same type and the size supported by the DVR. However, once you install the hard
drive in your DVR, it will be formatted for use in the DVR and will not be read by your PC.
Q: Do I have to stop recording to playback files on the DVR?
A: No you do not have to stop recording, the DVR will support both functions at the same time.
Q: Can I erase files from the hard drive of the DVR?
A: You can not erase individual files. You would need to format the hard drive which will erase all of the files.
Q: Why can't I log-in to the Net-Viewer program?
A: Please verify that the Net mode is correct, the cable to the RJ-45 port is well connected to the DVR and the router,
and that you are using the correct password. Also check to make sure your ActiveX controls are enabled and your
pop-up blocker is turned off.
Q: We have attached a PTZ camera but cannot control it. What is wrong?
A: Verify that the protocol, baud rate, address and other settings on the PTZ camera match the settings you have put
into the DVR. Make sure the data cables are attached firmly to the RS485 port on the DVR.
Q: Why does the Buzzer keep sounding?
A: Check to see if the Motion Detection option is enabled on your system and discern whether or not your system has
detected activity. If no motion has been detected, check to see if the hard drive on your DVR has been recognized
and that there is sufficient space available. Another possibility to consider is that your cameras might have lost
video. If this occurs, check the power feed to the cameras and make sure that they are turned on.
