On the front of the camera unit, a blue flashing light will appear and a beep will sound as a signal for someone on the other side to talk.

At the top of the lens is a single LED that flashes blue when the camera is trying to connect to the network, and stays solid green when it's on and recording. The entire unit measures 4.5 x 2.8 x 2.8 inches, with a leg that rotates 180 degrees, and the camera head atop it that rotates a full 360 degrees.
Placing the camera in a corner will capture the entire room, and then some. The Nest Cam comes with a magnetic base and a wall-mounting plate and hardware, giving you several options for camera placement: on the wall, standing on a flat surface on a tripod or even stuck on the fridge.
The Mimo baby monitor and onesie will trigger the Nest Cam to start recording if a baby moves.
