Security camera

Smart cameras, expressive.

when they see you they look like they take notice, and perk up, and look at you and track you, shining light on you and causing nearby security bot to come check out the alert. 

has a little alert light that spins up when its sending alert to the guard. 

think about how the pixar lamp works with its head is the lamp and its face is the light. 

think about the design of the robots from Wall-e on the ship. 

simple, started clean, isnt now.

uses facial minimal expression for maximum performance.
