Description of detector board interface:
1. LED indicator
3 pins: Top, centre, bottom
1. Jumper set to top and centre (see left picture):
If motion is detected, the LED blinks. Hence
the camera is easy to be identified as a
security system device.
2. Jumper set to centre and bottom:
No LED blinking at motion detection. Hence
the camera is less obvious to intruders.
2. Sensitivity adjustment
Increase the sensitivity:
Turn clockwise to detect longer distance and
wider pattern.
Decrease the sensitivity:
Turn counter-clockwise to detect shorter distance
and smaller pattern.
3. Dwell-time adjustment
The dwell-time adjustment controls how long the
alarm remains triggered after activation.
Max. dwell-time: turn clockwise
Min. dwell-time: turn counter-clockwise
The top and centre pins of J4 have to be selected.
4. Light control and recording control
3 pins: Top, centre, bottom
1. Jumper set to top and centre (see picture left):
Use “VR2” to set the time. To set the relay time
of the light control and the recording control,
the time is selected by individual preference or
application.
2. Jumper set to centre and bottom:
Relay time is fixed to 2 seconds.
Note: N.C./N.O. maximum relay charge:
