5. Dipswitch Setting
5.1 AES Function- The AES (Automatic Electronic Shutter) function
controls the brightness of the camera image, it should always be
in the AES position.
5.2 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 dipswitch to the BLC position, to turn it off, flick the dipswitch
to the OFF position.
5.3 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 dipswitch to the AGC position, to turn leave it as normal,
flick the dipswitch to the OFF position.
5.4 Flickerless Function- The flickerless function is designed to
improve the images and colour balance when using the cameras
where Fluorescent Lighting is present. To turn on the flickerless
function flick the dipswitch to the F.L. position, to turn it off, flick
the dipswitch to the OFF position.
