Appendix 4: Connecting Motion/Alarm Devices
Motion detection and Alarm controls are enabled through the Menu system on the DVR.
Additional motion sensor devices can be connected to the system (Motion Sensors, Door/
Window Sensors).
A motion detection or sensor unit can be used to send a signal to the DVR to begin camera
viewing on the matching Video Channel (when enabled in the Menu):
• Example: A Window sensor unit has been installed on Alarm Block port #4. When this sensor
is activated, the camera on DIN or BNC VIDEO port #4 will become active (if enabled in the
MENU on the DVR)
Installing a Sensor
1. Connect the GROUND Cable to the GND port on the Alarm Block on the DVR
2. Connect the SIGNAL Cable to a numbered port.
To start ALARM RECORDING on the System, refer to the Menu Configuration section of this
manual.
