Not only can it notify you if there’s movement in your home, it can differentiate between people and animals, and – what’s really remarkable – it can even identify if it’s a familiar or unfamiliar person. The Nest Cam IQ also has the best image quality of any of the cameras we’ve tested, shooting in 4K and HDR high dynamic range. If someone is in your home, you’ll have crystal clear images of them. The main drawback with the Nest Cam IQ is that to use its full range of functions you’ll have to purchase a subscription to Nest Aware. But if you want the best quality, the Nest Cam IQ is probably the camera for you, especially if you find a deal. It’ll be lighter on your pocket too.
