What is the use case? Trail cameras already do this and they cost $50 instead of $200 with better photo quality and better motion sensing.
Oh and they take video too.

Plus all the other reasons others said.
Would you have some specific model in mind, and what aspects of photo quality & motion sensing are better ?
For sure, I never seen a so nicely managed battery life.
A $50 trail cam will take at least 10MP photos, will have night vision and will be able to take videos. People have left trail cams out for over a year and they were still taking photos.
Battery life is cool, but if existing devices already have more life than anyone needs what's the point?
