3 DESCRIPTION
These environment-resistant cameras provide reliable,
unattended, continuous service in demanding CCTV
applications. Their low power consumption, high
sensitivity, and stability make them an excellent
choice in surveillance and industrial applications.
3.1 Power
Refer to the individual camera instructions for power
requirements of the camera. These housings employ an
integral heater which adds an additional 10W to the
power consumption.
3.2 Environmental Enclosure
3.2.1 Construction
These cameras are self-contained (within one case), with a
single corrosion-resistant connector for power, video/

control, lens control, and external sync. Note that
some cameras do not have external sync capabilities. A
mating connector is provided for each camera.
The exterior of the camera housing is 4mm (0.16in.)
aluminum, which ensures a rigid, rugged structure.
The camera housing is sealed at both ends by radial
pressure O-rings to create a tight seal. Fore-and-aft
movement of the camera cradle is further prevented by
a retaining screw (located at the rear of the housing).
See FIGURE 3. Chemically strengthened glass is used
for the faceplate for maximum strength and safety.
The camera is fitted with a standard Schrader valve,
to allow pressurization with dry nitrogen to
35kPa (5PSIG) nominal at one atmosphere. An over-
pressurization safety relief valve is mounted on the
back end cap, along with the Schrader valve. The
relief valve provides a safety pressure blow-off,
between 100kPa (15PSIG) and 140kPa (20PSIG) at
one atmosphere.
3.2.2 Heater
The front end cap contains a glass viewing window
with an integral heater/defogger to minimize window
fogging in high humidity areas, and freezing under
cold temperature conditions.
3.2.3 Humidity Indicator
The camera housing contains desiccant material and a
humidity indicator visible from the front of the camera
through the glass window. The three areas, normally
blue, turn pink as the internal humidity increases. The
indicator provides an extra measure of reliability for
the camera, and indicates whether service is required.
