The camera trigger driver supports several backends - each for a specific application, controlled by the [TRIG_INTERFACE](../advanced_config/parameter_reference.md#TRIG_INTERFACE) parameter:

| 1 | Enables the GPIO interface. The AUX outputs are pulsed high or low (depending on the `TRIG_POLARITY` parameter) every [TRIG_INTERVAL](../advanced_config/parameter_reference.md#TRIG_INTERVAL) duration. This can be used to trigger most standard machine vision cameras directly. Note that on PX4FMU series hardware (Pixhawk, Pixracer, etc.), the signal level on the AUX pins is 3.3v. |
|
||||
| 2 | Enables the Seagull MAP2 interface. This allows the use of the [Seagull MAP2](http://www.seagulluav.com/product/seagull-map2/) to interface to a multitude of supported cameras. Pin/Channel 1 (camera trigger) and Pin/Channel 2 (mode selector) of the MAP2 should be connected to the lower and higher mapped [camera trigger pins](#trigger-output-pin-configuration). Using Seagull MAP2, PX4 also supports automatic power control and keep-alive functionalities of Sony Multiport cameras like the QX-1. |
|
||||
| 3 | This mode enables MAVLink cameras that used the legacy [MAVLink interface listed above](#mavlink-command-interface). The messages are automatically emitted on the MAVLink `onboard` channel when found in missions. PX4 emits the `CAMERA_TRIGGER` MAVLink message when a camera is triggered, by default to the `onboard` channel (if this is not used, custom stream will need to be enabled). [Simple MAVLink cameras](../camera/mavlink_v1_camera.md) explains this use case in more detail. |
|
||||
| 4 | Enables the generic PWM interface. This allows the use of [infrared triggers](https://hobbyking.com/en_us/universal-remote-control-infrared-shutter-ir-rc-1g.html) or servos to trigger your camera. |
