4.2.10 Digital Input Configuration
The sensor (alarm) inputs comprise LED type photo-couplers. The specification
of the input is 5 to 12 Vdc at 10 to 20 mA
Recommendation: Activate the sensor inputs in one
of the following ways;
1. Connect sensor input minus (SEN-) to
ground (GND) and use a relay or switch to connect
the sensor input plus (SEN+) to +12 V (POW).
2. Connect sensor input plus (SEN+) to +12 V
(POW) and use a relay or switch to connect the
sensor input minus (SEN-) to ground (GND).
NetCam2 sends e-mails or/and files when connected external sensors detects an
event.
• Active State for Input Port 1 – define the normal state of connected input
devices such as infrared sensors.
• Current Status for Input Port 1 – NetCam2 shows the current state of the
two connected digital devices. Their states are defined at ‘Active State for
Input Port 1 and 2’ menus.
