Motion detection multi shot over long time period

[mgrant]

Is it possible to set up motion detection to take multiple shots over a long period of time, say all night?  For example to use the camera as a sort of security camera or to catch animal shots when you don't know when the animal will visit the scene.

Liveview won't stay on for longer then 30mins without user interaction.

But when you take a timelapse using silent shutter, it's in liveview, isn't it?  Is the fact that an image is being recorded resetting this 30min timeout?  Could something like this be used to get around this timeout?

Pressing the shutter halfway will reset the timer.
