PROBLEM SOLUTION
Some cameras show video images in weird
colors or abnormal shapes..
Check the cameras connected to the system. Switch the camera
that displays defected images with the another camera that
displays images correctly, then you can check which camera
is not working properly or whether SPR-9816/9716 system is
defected.
Check camera video format types. Countries around the world
use different video broadcasting standards such as PAL, NTSC,
or SECAM. However each standard is incompatible with the
other in terms of video image transmission method and the video
image processing methods. In this case, video images will be
displayed, but not in recognizable shape. Check the video format
type sent from connected cameras and image processing
method set in [System Menu] are identical.
Displayed video signals have a lot of noise.
Check the cameras connected to the system. Switch the camera
that displays defected images with the another camera that
displays images correctly, then you can check which camera
is not working properly or whether SPR-9816/9716 system is
defected.
Check the cable connections between camera and
SPR-9816/9716. Check that these cables are not shorted,
mixed or disconnected.
Check the surroundings of cable connections between camera
and SPR-9816/9716. Check if there is any high-voltage power
line around the cable connections. If there is a high-voltage
power line nearby the cable connections, it can degrade video
image quality or causes noises.
Check the cable connections between camera and
SPR-9816/9716. Check if the cables are the correct type for
transferring video signals. If you have used for example power
cables for video image transmission, it can cause noise on the
displayed video image.
Sometimes the system reboots without any
cause.
If SPR-9816/9716 is not working properly, or there is malfunction,
the embedded self diagnosis feature might cause the system to
reboot.
Connected sensors are not working
properly.
Check the sensor types set in Camera Setup menu are identical with
the sensors actually connected to the system.
Check if the system’s sensors are enabled in the [Recording Setup]-
[Recording Schedule] menu.
Check if the sensors are correctly connected to power source.
Check if the sensors’ signal lines are correctly connected.
Connected control devices are not working
properly.
Check if the control devices are enabled in the Camera Setup menu.
Check if the control devices are correctly connected to power
source.
Check if the signal lines of the control devices are correctly
connected.
