Event Configuration >> GPIO Setting
1. I/O Connection
Please connect the GND & DO pin to the external relay (buzzer) device.
When no event occurs, DO output is 5V (DO and GND are disconnected). When
the camera detects event happening and triggers external alarm, DO output is
0V (DO and GND are connected).
Please connect the GND & DI pin to the external trigger device.
If you select "N.O" in "Input sensor setting", when external devise or circuit
makes DI and GND pin connected, the camera input alarm is triggered, and then
camera will execute the action user has set, for example, send snapshot to E‐
mail address.

If you select "N.C" in "Input sensor setting", when external devise or circuit
makes DI and GND pin disconnected, the camera input alarm is triggered, and
then camera will execute the action user has set, for example, send snapshot to
E‐mail address.
GPIO PIN definition
GND (Ground): Initial state is LOW
DO (Digital Output): DC 5V
DI (Digital Input): Max. 50mA, DC 5V
2. GPIO Setting
Event Configuration >> GPIO Setting >> Input Setting
Input Sensor: According to your external device and circuit design, select N.O
(normally open) or N.C (normally closed).
Input Action: When the camera input alarm is triggered, it can trigger the relay
out, or send the video to E‐mail/ FTP/ SAMBA.
Interval: If you select "10 sec" here, once the input alarm is detected and action
is triggered, it cannot be triggered again within 10 seconds.
Based on the schedule: When click the option box, only during the selected
schedule time the I/O is enabled. That is, for example, the 11th hour of Monday
has not been colored in the schedule table, then no action will be triggered even
the camera detects input signal during 11:00~12:00 on Monday.
