A time-lapse system controller is intended for long term time-lapse projects, which may last for many years at a stretch. In addition to camera shutter timing, a system controller must manage power to and from a battery pack, interaction from the operator, and a variety of other functions depending on the specific application.
The DigiSnap Pro is the first time-lapse system controller to be offered for general sale, not just used in proprietary systems. You are welcome to use the DigiSnap Pro in your own time-lapse projects, DIY or commercial.
Let's take a quick look at the connections provided on the DigiSnap Pro. There will be more videos and documents which go through the details, but I'd like to briefly touch on each now.
