Resolutions
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 connected
correctly.
Check the connected speaker is working properly.
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 output.
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.
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 system
is the correct video cable. When a normal power-supplying cable is used
instead of the video cable, screen noise can be generated.
Check the type of sensor in the camera setting is the same as with the con-
nected sensor.
Check the system is set to use the sensor in the recording schedule window in
the recording setting menu.
Check the sensor is properly connected to the SENSOR-IN.

Check the power cable of the PTZ camera is properly connected.
Check the signal cable of the PTZ camera is properly connected.
Check the selected channel to control the PTZ camera.
