Can you/ how can you record events to your SD card and change lengths of time?
The way it works is recordings to the uSD card are always 1 minute long. If you have the camera set to record events only, any minute that has activity will be saved to the uSD card (regardless of where in that minute the event occurs). If you have the camera set to continuous recording, then all minutes will be saved to the uSD card.
Does that answer your question?
