The Arlo Ultra ($332) is the best indoor/outdoor motion sensor camera for two reasons. First, it has the best video quality. It includes an extra-wide field of view (180 degrees), 4K ultra HD video and color night vision. Second, Arlo’s home security camera includes helpful features such as a siren, noise-canceling technology with the two-way talk option and a spotlight.
Not only does it detect motion, it can tell the difference between humans, pets and vehicles, so you can customize your motion alerts and recording preferences. Plus, it’s wire-free and runs on a rechargeable battery.
