The outlines of a second image
can be seen.
No image. You press the image
key, but nothing happens.
After a while, the video image
turns white. If the power supply
voltage
of the external unit is switched off
and back on again, the signal is
in working order again. The image
still turns white after a while.

Open cables create image reflections, so-called
ghost images
Two video sources are placed over one another.
You don't receive a signal.
The conductors of the video bus are not both connected.
Thermal defect at the external camera.
The video circuit is not closed. Place the terminal resistor
on the last device on the circuit.
Remove the second video source from the circuit. If
necessary, bring them together via a video switch using
the existing bus.
Connect the monitor before the video switch and see if
you now receive a signal.
Measure the voltage between P and b. The voltage should
be approximately 24 V. Otherwise, the bus power supply
must be checked.
Check whether the plug-in terminal is establishing a
correct connection.
One of the conductors of the video bus causes a short
circuit with the P or b wire. This is causing too much
voltage to go to this location.
Please check the cabling for short circuits.
The camera is defective.
