Application Note
1. Power, video out and Key board Interface
A power board has been added to the main board to allow 12V DC input. 2 connectors are provided for
connecting the video and key board connection. A demo key board has been provided for testing purpose.
Customer can build his own key board for real production.

2.2 Alarm Output
The module use XGPIO0 as alarm output, active low. That means, when there is a motion detect
from the image sensor, it will output a low signal. Normally this pin is high, 3.3V
2.3 Trigger Input
The module use ADC1 as trigger input, active low. That means, the module can accept external
trigger signal to do the capture function. It is internal pull high (3.3V).
3. IR Remote control
If user wants to use IR remote control circuit, need to contact the supplier for the version which support IR
remote control.
