Troubleshooting
Problem Solution
No picture.
Make sure the cameras and receiver are plugged in.
Make sure the TV/ VCR/ DVR is tuned to the correct input
channel.
A white image appears at
night.
The camera's infrared LEDs shine invisible light that
reflects off surfaces such as glass causing white light.
Place the camera on the other side of windows or place the
lens flush against the surface to improve night vision.
Relocate the camera to a well-lit area.
The display turns off after
30 minutes. This is a feature of the product designed to protect the LCD
screen from overheating and burning out.
Why does the DVR run
slow when it starts?
There may be too much data on the HDD. The DVR checks
data when it starts and this may cause the system to start
slowly.
HDD error – The system tests the HDD repeatedly during
startup and this may cause the system to start slowly.
Why does the system keep
rebooting after the host
self-test?
Check the HDD. Make sure the HDD partition is not in the
FAT32 format, and that the HDD does not have a problem.
Either of these situations could cause the host to reboot.
Check Video Parameter setting, if the host is in the PAL
state but the video input is NTSC, the host will keep
rebooting.
Why does the system turn
off when a video is playing
or when checking video
information during the
normal routine? Check the HDD connection and make sure it is secure.
Change the HDD if there is a problem.
Why does the video
display only in black and
white? Check to make sure the video input, DVR host, monitor,
and TV format match. If they do not match, set the monitor
or TV format to the auto detect state.
Why does real-time video
and record data have color
and light distortion
problems? Reboot DVR, in order to recover previous settings.
Adjust Video setting in the DVR setting menu.
