Surveillance cam
From Wookieepedia, the Star Wars wiki.
A Surveillance cam was a security device that could be used to spy on people, or to look after a place. They could be disguised into a number of ingenious locations. Chay Praysh used them throughout his fort to keep things in order. Mara Jade was able to pass undetected in the the fort as she flung mud into the lense of the camera.
