There are plenty of connected camera options out there. But there's only one that's totally wire-free. The Arlo Smart Security Camera is a 100% wireless security camera solution, offering 720p video resolution and the ability to run up to 6 months on a single set of batteries. The cameras are waterproof, so they're outdoor-friendly, with motion sensors for real-time alerts, night vision capability for clear images even in the dark, and magnetic mounts that make it easy to move them from place to place. The starter kit includes two cameras, four mounts, and a smart base station that can also talk to other devices; extra cameras sell for $170 a pop.
