Looping Output Termination
When terminating the outputs becomes necessary, the DVR has built-in termination
that allows the user to select individual outputs to be terminated. Generally it is not
necessary to terminate the output when using it. It is dependent on if the device, to
which the user is 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.
NOTE:
Always leave the dipswitch set to the ON position when the Looping Outputs
are not used.
Connecting Sensors to the DVR
Each DVR 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 Sensor inputs can be set to Normally Open or Normally Closed
within the Fusion Server 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.
•
Normally Open or Normally Closed options are set within the DVR Software.
•
There is no power supplied to the ports. These ports are considered to be
“Dry Contacts”. Use an external power supply if necessary.
