DESCRIPTION

The EH2020 is a small, low-profile ceiling enclosure designed for mounting in fixed or dropped
ceilings. It is used for indoor applications only. The unobtrusive, compact design complements
any business or office decor and provides maximum discreet surveillance.

The EH2020 is constructed of steel and is engineered for ease of installation and service. The
back box is mounted above the ceiling and can be mounted directly on a ceiling tile with the
use of two soft-ceiling mounting brackets (included).

The lid is attached to the back box with two tamper-proof screws and is retained by a leash
when removed. When removed, It provides convenient access for adjusting the camera and
lens. The enclosure has an adjustable camera mounting sled to accommodate cameras of
varying sizes.

The EH2020 has an optically clear, impact-resistant Lexan® viewing window which allows no
loss of light to the lens and camera.
