Connecting Motion / Alarm Device - Appendix #13
Motion detection and Alarm controls are enabled through the Menu system on the System. 
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 System 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 System)
Installing a Sensor
1. Connect the GROUND Cable to the GND port on the Alarm Block on the System
2. Connect the SIGNAL Cable to a numbered port (1-8) 
To start ALARM RECORDING on the System, configure the System Menu.
