U.S. Army Yuma Proving Ground
YUMA, AZ - The US Army Base at Yuma Proving Grounds in Arizona had a requirement to secure four hub areas using CCTV cameras for surveillance. Video from
each of the hubs was to be brought back to the head-end
location for monitoring. The four hubs were located at
3,200 (975 meters), 6,400 (1,950 meters), 9,600 (2,926 meters) and 12,800 feet (3,901 meters) from the head-end
monitoring area. Because of the distances involved, coax
was out of the question. Fiber optic cable would have to
be trenched and the cost of fiber, installation and the associated
equipment for transmission would far exceed the
allotted budget for this project. UTP 18 gauge cables existed
between each of the four hubs and the head-end. This project was “ready-made” for the Nitek long haul
UTP solution. In fact, the Nitek UTP transmission equipment
provides results equivalent to or better than fiber
quality at the cost of copper.
The NITEK Equipment Solution
Since cable runs covered a range of long haul distances
from 3,200 to 12,800 feet (975 to 3,901 meters), the Nitek Modular system
was selected as the UTP system solution. The Modular
system uses an RK400 19” rack mount chassis that accommodates
up to 10 plug-in receiver cards. The cards
come in four models covering a range from several feet
to 12,000 feet (3,658 meters) and can be mixed in any combination. Two
RK400’s were used in this application. For the 4 cameras
at the first hub, at 3,200 feet (975 meters), the EX560x4 system was
used. The EX560x4 consists of a single TR560x4, four
channel plug-in receiver and four individual TT560 active
transmitters, one for each camera. For the balance of the
three hub locations, 4 cameras each at 6,400, 9,600 and
12,800 feet (1,950, 2,926, and 3,901 meters), twelve EX1120RR systems were used. The
EX1120RR is a complete system that consists of a single
channel plug-in receiver and a single standard active
transmitter for each camera.
The system has cost-effectively provided security at four
remote locations by making use of existing infrastructure
to solve the problem. As an added benefit, since only 13
of the 20 available slots in the RK400’s were used, 7
slots are available for future growth of the system.

LONG HAUL VIDEO MADE EASY WITH DAT TECHNOLOGY
The ease of transmitting high quality
video over existing UTP cables for
long distances in the Yuma project
was made possible by the Nitek model EX1120 Long Haul Video
Transmission systems. The EX1120
in both the stand-alone and rack
mount card versions utilize the unique
Digital Adjustment Technology (DAT)
available only from Nitek. DAT provides
the means to accurately adjust
transmitted video to 1 V P/P for guaranteed
reliable operation with DVR
equipment.
