The Arlo Ultra and the Nest Cam IQ Outdoor are two high-end home security cameras, by far the most specced-out DIY outdoor models I've tested.

Both cameras have 8-megapixel image sensors, which allows them to automatically zoom in on a person, a car -- or some other motion activity -- and track it more closely than a standard cam.

Both cameras have impressive specs, making this section a draw, but there are some key differences worth discussing.
