Arlo Smart Home Security Camera System
The Arlo smart home camera from Netgear is a completely wire free camera. It operates on Wi-Fi and is powered by CR123 lithium batteries. Netgear reports that a set of batteries will last six months, but your usage will vary depending on temperature and usage. The cameras go to sleep until they sense motion. The Arlo is weatherproof, so you can put it inside or outside (includes night vision).
