Entrance Panel
– Important Note
Careful consideration should be given to the location of the entrance panel to ensure the
best possible lighting conditions for the camera. In general strong back lighting of the
subject (by the sun and sky) should be avoided, as the contrast between foreground and
background may be too great for the camera. The field of view should contain as little of
the sky as possible, particularly if south facing. If a backlit situation is unavoidable,
additional lighting may be necessary to illuminate the caller and avoid a dark outline image
(silhouette). A light coloured or reflective surface around the panel will redirect backlight to
illuminate the caller.
Door Controller
The door controller and power supply should be wall-mounted in a convenient cupboard or
other protected environment with available mains power. Cable length to the entrance
should be less than 50m. The door controller for the second and subsequent entrances
may be situated in the same location, or to meet the 50m requirement may be situated in
another location. Power supplies may be shared between door controllers placed in the
same location, but controllers in separate locations must be separately powered.
