Nest launches outdoor camera for home security
The camera is constantly recording and uploading footage to the cloud, so you'll be able to check back on any timespan of interest, and it shoots at 1080p with a 130-degree view, so you should be able to make out relevant details.
It does need to be plugged into an outlet and doesn't feature on-board storage though, so a power outage or WiFi drop could render it useless.
