The Alarm & Sensor I/O Block - Swann Digital Video Recorder Manual

English
The Alarm Ports on the DVR sport a removable terminal block.
The terminal block is used to facilitate easy connection and
disconnection of so many wires, rather than having to unscrew
each one individually if you want to move the DVR or access
the rear panel.
Alarm In 1 - 4: Connect the output from external sensors
here. Only one of the two outputs should be connected here,
the other should be connected to a 12V terminal and/or the
Ground terminal, depending on the requirements of the
sensor (consult the documentation for the sensor).
The Alarm In number does not directly correspond with a
channel number - these can be set later (see "Alarm: Sensor"
on page 46 in Advanced Configuration for details).
