2 Troubleshooting
Problem 1:
Why does the camera restart intermittently? And the problem is
much more serious when infrared lights of IR camera are turned on
at night.
Possible Reasons:
The main and common reason is power supply shortage. This
problem may happen to the IR camera especially at night, because
the infrared lights are turned on at night and increase the power
consumption.
To Solve the Problem:
You need to ensure that the power supply matches with
±
10% of
the nominal voltage. And the power consumption of power adapter
should meet the demand of the camera.
Problem 2:
The camera can never be focused by adjusting the focus-stick on
the lens. And there is also no use adjusting the back focus.
Possible Reasons:
The camera needs the lens with CS lens mount. When you install a
lens with C lens mount, the camera will never focus.
To Solve the Problem:
You can change a lens with CS lens mount to the camera.
Or you can use a C/CS adapter ring between the camera and the
lens with C lens mount.
