Operating Instructions and Installation Instructions

CamVu Mini Dome

Use the direction buttons to navigate the menu, and to select parameters.

Exiting the Menu System

The menu system can be exited by selecting SAVE AND EXIT with the up/down menu buttons and then

pressing the Enter button. Any changes made while within the menu system will be saved. The menu system

will be automatically exited if a key is not pressed for 2 minutes.

Exposure

Hi is intended for general usage including brightly lit outdoor scenes and indoor scenes which contain a view

outdoors. It maintains optimum contrast in the darker portions of a wide dynamic scene.

Lo(w) may be used for indoor scenes, where the contrast between the brightest and darkest parts of the

picture is low. It maintains optimum contrast in the brighter portions of a wide dynamic scene.

AGC

This affects the way in which the camera displays scenes with lower illumination levels.

DnR gives the optimum performance for stationary or slow moving objects. DnR is a Digital Noise Reduction

system that reduce AGC noise by means of a eld integration algorithm. A consequence of DNR is that

moving objects can appear blurred at very low light levels. This setting has a maximum gain of 24dB.

Motion provides a clear image of moving objects but may introduce noise into the darker parts of the picture.

This setting does not use DNR at high gain. The images are sharper than DNR but the visible gain in the

image is greater. This setting has a maximum gain of 24dB.

Low is less sensitive at low light levels and provides a relatively noise free picture. Setting the AGC to LOW

reduces the camera’s performance at low light, but improves image quality in bright conditions. This is the

preferred setting for well-lit scenes. This setting limits the gain to 7dB.

White Balance Range

With some street lighting, for example sodium or mercury lamps, the camera may show an overall colour

hue instead of white. In these situations, setting the White Balance Range to Wide corrects the white

balance.

PRO (default)

This setting limits the white balance range to 2800 - 6500K. This provides a more accurate colour rendition.

WIDE

This setting extends the white balance range to 2500 - 9500K

Video Output Colour/Mono Mode

The video output is set to Colour by default. Set it to Mono for video output in monochrome or to C/M for

colour in normal light and monochrome in low light.

Fluorescent Lighting

Under some types of uorescent lighting, the colour may cycle. Set Fluorescent to On to help reduce this.

Alternatively, line-lock may reduce this problem (see Using AC Line Lock below).

Reduces colour rolling that may occur under some types of uorescent lighting. For best results, line lock

synchronisation is recommended. If line lock synchronisation is not possible, an auto-iris lens should be

used.

OFF (default)

The default setting maximises dynamic range
