OVERVIEW
The Digital Video Motion Detector (DVMD) measures 3.5"x5"x1.25" and is housed in an extruded
aluminum case as shown in Figure 3.
Figure 3 – DVMD-X
The unit receives video from the camera through the BNC connector labeled VIN and provides
buffered video output (after internal processing, clamping, automatic gain control (AGC), and
overlay) through the BNC connector labeled VOUT.
The Screw Terminal (Digikey 277-1166) provides access for +12 volt DC power, opto-isolated
input and dry contact relay alarm output. The opto-isolated input is active when driven from an
external voltage source between 4 to 24 volts. The function of the opto-isolated input is
application dependent. A dry contact relay alarm output is also provided. The pin connections for
these functions are shown in Table 1 below.
