Automated laser trap

Laser traps were automated blasters that were attached to a sensor set for automated targeting. Laser traps were used in the Death Star detention level.
Technical Information
The most common kind of laser trap was the BlasTech Class VI automated laser projector. It had a small control computer, a sensor suite, and a small blaster. It could be controlled automatically or through a remote.
The device could rotate forty-five degrees in any direction, with a range of twenty-five meters. They could also be configured to fire stun bolts instead of blaster bolts.[source?]
