Surveillance Positioning Devices
A scanner is a low cost positioning unit that only moves from side-to-side
(pan). Pelco
scanners feature camera-mounting tables with manually adjustable tilt ranges.
Units also
feature manually adjustable limit stops allowing the camera to rotate past 360
degrees to
380 degrees before reversing direction.
A remote controlled positioning unit capable of vertical (tilt) and horizontal
(pan) motion is
referred to as a pan/tilt unit. Pan/tilts range from light duty to heavy duty,
and from indoor only to outdoor models. Units can be configured to fulfill the
requirements of many special
applications and are capable of auto/random scan operation when used with an
appropriate
control.
Note: For fully integrated pan/tilt positioning systems, including optics
package, see
Esprit® and ExSite™ in the Camera Systems section of this book.
Legacy®
The Legacy integrated system is an innovative arrangement of “building block”
components
designed to simplify installation and system design. System components include
an
enclosure, pan/tilt, receiver and wall mount. The Legacy is capable of
355-degree or
continuous 360-degree pan rotation and fixed or variable pan speed, depending on
model.
Units are available with optional heater, defroster, blower, thermal insulation,
and sun
shroud.
Indoor
Pelco’s indoor pan/tilts are ideal for basic, low cost installations. Maximum
load capacity
varies per model and ranges up to 15 pounds.
Outdoor
Pelco has a complete product line of medium-to-heavy-duty scanners and pan/tilts
for
outdoor applications. Models include an explosionproof pan/tilt, rated for Class
II, Division I
hazardous locations. Maximum load requirements vary per model and range from 35
pounds
up to 100 pounds.
When choosing a Pelco positioning system, consider the maximum load the unit is
capable
of handling. The total weight of the camera and lens package, plus the enclosure
and any
accessories must be calculated. Refer to the specification sheets and choose a
unit that
exceeds your calculated weight
