3.8 LOOPING OUTPUT TERMINATION
When terminating the outputs becomes necessary, the DVR unit has built-in
termination that allows you to select individual outputs to be terminated. Generally it is
not necessary to terminate the output when using it. It is dependant on if the device to
which you are connecting it, has internal 75 ohm termination. As a rule, if the image
appears distorted or virtually un-viewable, it most likely needs to be terminated.

3.9 CONNECTING SENSORS TO THE DVR
Each DVR unit may have up to 16 Sensor inputs. These inputs can be used with
devices such as Infrared sensors, motion devices, glass break alarms, door and
window trips, and many more. The Sensors inputs can be set to Normally Open or
Normally Closed inside the software.
There are 4 Commons (-) and 16 inputs (+). There is no power supplied to the ports so
an external power supply must be used if power becomes necessary.
