Before you begin
z Please unpack the box carefully and identify that all the parts are present.
z The camera is suitable for indoor or outdoor use. Please bear in mind the following points when choosing a mounting position.
- The camera must be positioned so that it will not point directly into the sun (sunrise and sunset) or any bright light, as this may cause damage to the camera.
- Avoid viewing areas where half the area is in bright sunlight and the other half is dark, such as in the shadow of a building. All types of cameras have difficulty in ‘seeing’ with such a large lux level variation.
z Do not cut the camera cables, this will void the warranty.
z Make sure you use only the recommended power supply. Damage caused to the camera by incorrect voltage or wiring is not covered by the warranty.

DIP Switches on the Camera Board
BLC
AE
AWB
AGC
5.1. BLC Function
The BLC (Back Light Compensation) function makes objects in front of a bright scene (such as a window on a bright sunny day) clearer to see by increasing their brightness and making the background darker. To turn on the BLC function flick the DIP switch to the BLC position, to turn it off, flick the DIP switch to the
OFF position.
5.2. AE Function
For better performance in low light conditions the AE (Automatic
Exposure) automatically detects the light level and maintains a clear picture if this mode is activated.
5.3. AWB Function
The AWB (Automatic White Balance) feature automatically adjusts the colour temperature of the camera image to match the type of light available, so that white and other colours appear as natural as possible. It should always be in the AWB position.
5.4. AGC Function
For better performance in low light conditions the AGC
(Automatic Gain Control) can be increased from the standard
16db to 26db. This has the effect of making the picture brighter
(however it may also add more noise to the picture, as it is amplifying all aspects of the video signal). To increase the AGC flick the DIP switch to the AGC position, to turn leave it as normal, flick the DIP switch to the OFF position.
