Pelco Manual C1446M-B (7/98)

The EH4712DB and EH4718DB environmental enclosures are constructed of alu-
minum. The enclosures are installed by attaching the top of the unit to a mounting
surface. A door in the bottom drops open for access during installation or to make
camera/lens adjustments.

You can install cameras with either fixed focal length lenses or motorized zoom
lenses. All models have an adjustable camera sled to accommodate different sizes
of cameras and lenses.
