Product Overview
The CMD-2 motion sensor can be used in a wide variety of applications. The primary purpose of the
sensor is to detect motion and provide additional information about the moving target. The sensor is
designed to take advantage of one of the primary features of its technology, which is its ability to see
through earth, concrete and other standard building materials. Other motion sensors need a window
onto the world, the CMD-2 does not, and it can be completely buried where it is protected from
tampering and from the environment.
One application of the CMD-2 is to protect buildings and premises from entry by unknown persons
or vehicles. Used in conjunction with CCTV systems the CMD-2 can establish a powerful barrier to
identify and track unknown intruders long before they enter a building. Sensors may be placed almost
one quarter mile from the security center, giving the phrase ‘detection beyond the fence’, whole new
meaning. Longer distances are possible with fiber optic or wireless Ethernet connection. Because the
CMD-2 is buried, intruders cannot see or disable the sensor. False alarms are minimal.
The sensor can be buried up to eight inches beneath the surface of earth, roads or walkways. The
material covering the sensor can be concrete, granite, earth, bricks, etc. The only limitation is that the
sensor cannot be covered with sheet metal or a dense metal mesh material.
The radial range of the sensor is 22 to 25 feet (6.5 to 8 meters) and it covers an elliptical pattern on
the ground (or approximates a hemisphere in 3D). It is able to detect motion from any direction.
Therefore with a fifty foot diameter of coverage multiple sensors can form a ring or fence around a
facility. When a sensor detects motion an alarm signal is generated and recorded. As an option, a
designated CCTV camera can point in the direction of that sensor and record the target and its
activity.
Each sensor is powered through its Ethernet connection (standard CAT-5 burial cable). The
connecting cable from the sensor to a concentrator box (CB-06) and then to the server can be up to
400 feet (123 M) long. Longer cable distances requires daisy-chaining concentrator boxes (CB-06).
Up to four concentrator boxes can be daisy chained resulting in a total cable distance from server to
sensor of 1200 feet (393M). A separate power cable is required for daisy-chained concentrator boxes
(hubs). See the attached diagrams for these two connection methods. Note that Ethernet has a
limitation of 300 feet (91 meters)maximum between hubs. The use of remote power sources can
increase the distance to any desired range.
The two connection methods of daisy-chain and direct connection can be used together in a single
security system. The limitations are defined by the number of sensors that can be powered by the
server. Three standard servers are available; they are designed to control, monitor and power up to
8, 24 and 48 CMD sensors. Custom systems can be designed as required.
