2.7 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 unviewable, it most likely needs to be terminated.

2.8 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 devices,
motion devices, glass breakage alarms, door and window trips, and many more. The Sensors 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.
