not playing.
Check the audio recording option is correctly set for the camera you wish
to record audio.
Check the speaker and audio (line input) on the rear of system are con-
nected correctly.
Check the connected speaker is working properly.
The colors of some
camera videos are
strange or videos
are displayed abnor-
mally.
If the camera connected to the system has a problem, make sure that the
camera is not damaged by trying another camera into a working video out-
put.
Check the video format setting of the unit is the same as the connected
camera’s video format. Depending on your region, the camera’s video
format can support either PAL or NTSC. Depending on the camera’s video
format, the video process can differ greatly, therefore it can be difficult to
recognize the video data if the video format setting is different from the
camera’s video format.
There is a lot of
(screen) noise
accompanying the
image.
Check if the video signal output from the camera has a problem. Ensure
the camera is not damaged by trying another camera with a working video
output.
Check if the video cable connection between the camera and the DVR is
cut, crosswired or shorted.
Check if there is a high voltage wire around the video cable connection
between camera and DVR system. It can cause interference and affect
video quality.
Check the video cable connection between the camera and the DVR sys-
tem is the correct video cable. When a normal power-supplying cable is
used instead of the video cable, screen noise can be generated.

sor is not operating.

dow in the recording setting menu.

ating.
