SurveyorVFT Fixed Dome Components
The SurveyorVFT fixed camera dome units consist of an enclosure/housing, a camera mechanism, a shroud, and
a smoked (indoor) or clear (outdoor) lower dome.
Enclosure
The enclosure is a metal shell that houses the camera mechanism for the in-ceiling model. A safety cord and clip
are provided to connect to the camera mechanism during installation. In addition, a small hole is provided on the
side of the enclosure for connection of the lower dome’s safety cord. A removable top cover, a 0.75-inch (19 mm)
conduit fitting and a pair of rotating flippers that give a convenient and sturdy connection of the enclosure into the
ceiling are provided. For in-ceiling installations that do not use conduit pipe, a 0.75-inch (19 mm) strain relief
fitting provides solid cable anchoring at the enclosure.
Camera Mechanism
The camera mechanism includes an integral camera/lens combination, with a color camera and a varifocal lens. It
is designed for easy “snap-in” installation into the enclosure or housing. The camera/lens position can be
manually adjusted. The integral PC board provides wiring connections. For outdoor units, a thermostatically-
controlled heater is provided for temperature control.
Shroud
The shroud is a 5.4 in. (137 mm) textured black ABS plastic shell. It has a 1.4 in. (35.6 mm) slotted opening for
the camera. This shroud conceals the position of the camera and snaps onto the camera drive.
Lower Dome
The lower dome is an assembly comprised of a 5.9 inch (150 mm) diameter acrylic plastic shell, a trim ring and a
safety cord. Lower domes for indoor versions come in a choice of smoked, chrome or gold finishes. Standard
outdoor lower domes are clear and use 4 screws for additional support. All lower domes are anchored to the
enclosure by the safety cord. Refer to the Maintenance section for care.
Housing
The housing for the SurveyorVFT fixed indoor pendant configurations is a molded plastic protective cover for the
camera mechanism; outdoor pendant configurations have a die-cast aluminum housing with a sunshield. The
housing has a 1.5-inch NPT pipe flange mount. In addition, the housing is equipped with a safety cord and clip
that is used to suspend the camera drive during installation. Another safety cord connects the lower dome to the
housing.
Sunshield
A sunshield pre-installed over the housing used on the outdoor pendant version is for radiation sun-blocking
protection.
CAUTION: For any environment subject to moisture, use the outdoor pendant model.
