Once constructed by Serv-O-Droid, Inc. for wealthy citizens and entrepreneurs, the TT-8L gatekeeper droid, also known as the gatewatcher droid and nicknamed the "tattletale," was made to be the perfect surveillance system.
Essentially, the droid was an electronic eye on a stalk. The "tattletale" was placed near a door and could poke its "eye" through a peephole in the door. It could then ask its master if it should admit a visitor or keep the visitor at the door. Many people considered it to be one of the most annoying droid models.
It could be modified into an advance scout droid by updating its programming to include piloting and mounting it to a fast vehicle.
