SECURITY CAMERA SYSTEM UPGRADE AND REPLACEMENT
FOR MONTGOMERY COUNTY DETENTION CENTER
SECURITY CAMERA SYSTEM 17000-77
6. Warranty
Minimum one year
13. SPEEDDOME ULTRA 8 22X CAMERA DOME
A. Description:
1. High-speed, programmable dome with high-resolution, DSP5, color
camera
2. 22X optical zoom, 11X digital zoom, and 242X total zoom capabilities
3. Dome to conform to RoHS initiative standards
B. The dome assembly must be comprised of a high-speed pan/tilt assembly, high-
resolution color camera with 22X optical zoom, 11X digital zoom permitting up
to 242X total zoom, and a horizontal resolution of 470TVL. The camera/lens
assembly must provide for continuous, full-time, autofocus capabilities.
C. The pan mechanism must incorporate a sealed precision slip ring to provide 360°
of continuous pan rotation. The tilt mechanism must provide for 110° of travel.
Precise manual panning and tilting must be achievable through a combination of
variable-speed operator control (speed ranges) and automatic adjustment of these
speed ranges dependent upon zoom factor. Manual pan and tilt speeds must range
from 0.25° to 100° per second. Preset pan speeds must range from 1° to 360° per
second, and preset tilt operating speeds must be from 1° to 220° per second. Pan
and tilt speeds will be automatically adjusted by the zoom factor to allow the
user the same ease of control, regardless of the field of view. High-speed, DC
direct-drive motors must be used to maintain high torque through the entire
operating range. These motors must use pulse-width modulation and encoder
feedback to control the acceleration, speed, and deceleration of the motors to
ensure smooth, precise, accurate, and fluid movement. The design shall use DC
direct-drive motors and no belt to ensure long-term, reliable operation.
D. The dome assembly must provide video transmission via unshielded twisted pair
(UTP) as standard.
E. The design of the dome shall not require the use of a bubble indoors to be
covert, but shall support the option of either a clear, smoked, silver, or gold
bubble.
F. The dome assembly shall contain a built-in, multi-protocol receiver/driver for use
with matrix switching systems using one of the following protocols:
1. AD Manchester control code and a single 18AWG shielded twisted pair
(STP) to support up to three daisy-chained domes a maximum of 1500m
(5000ft)
