Trigger Camera Automatically

Hi every one. I would like to know how to trigger my camara every 1 second in an automatically form. It’s already connected to software but it only triggers when i give the order Trigger Camera NOW and i need that happens every one second .Can someone help me?

For a time delay you probably need to setup an intervalometer in the camera ie: using CHDK scripts or inbuilt time lapse functions.
Depends on the cameras abilities.

We always use the Do-Set-Cam-Trigg-Dist mission command as we want survey images taken at specific distances not time, as the crafts speed can change depending on wind and payload. (copter or fixed wing)
