Philips LDH 0462/00 (VCM 6459/00T) Information Sheet  
Power Connector  
The camera can operate from either a 24V AC or 12V DC power supply. Connection is on an  
8-pin mini-DIN socket.  
AC Operation: Use pins 6 and 8.  
DC Operation: Pin 5 is +12V DC. Pin 2 is GROUND.  
Iris Connection  
A standard iris lens (one that has a built-in video amplifier and motor drive) can be connected  
to the 3-pin mini-DIN connector on the rear of the camera.  
Pin 1: GND  
Pin 2: Video Out  
Pin 3: +12V DC  
The camera also has a standard 4-pin iris connector for use with a passive iris lens.  
Back-Focus Adjustment

Set the lens distance to infinity  
Aim the camera at an object that is at least 15m away.  
Make a preliminary iris adjustment if necessary (see next section)  
Loosen the lens mounting ring by means of the small set-screw on top of the camera  
front.  
5.  
6.  
Turn the lens with the mount adjustment ring until the video picture is in focus. This is  
most accurate when the iris is fully open.  
Tighten the lens mount ring by means of the set screw.  
Iris Adjustment (Manual iris lenses)  
1.  
2.  
3.  
4.  
Install the camera in the position where it will be used. Aim and focus the camera on  
the area to be monitored.  
Set the iris to its minimum aperture. The camera will now show a low contrast picture  
with ‘noise’.  
Open the iris slowly. The picture contrast will improve and the ‘noise’ will gradually  
disappear.  
Set the iris to a position at which the details in the larger white parts of the picture are  
not washed out.  
 
Specification  
This specification has been derived from various sources, principally from the specification of  
the similar LDH0460/00 camera. I cannot therefore guarantee that this specification is  
accurate, but it does give a broad indication of the LDH0462/00 camera’s performance.
