So at the start of the hour, it freezes for a bit. On the hour, it clears out the cache of all the pics taken in the last hour, so it takes a bit of time to delete the old pics, reset and start recording again. And because it's a bit slow, it only ends up playing about 20 minutes of footage over each hour. So I'll have to make sure I feed/pat/snuggle them in the first 20 minutes of each hour
