Defense drone

Defense drones are small, unassuming black domes attached to the walls of strategically important rooms. Several moments are required for the drones to energize; once they are charged they launch a concert of needle-pricking energy bolts against aggressors, leaving small burns on the body of individuals.

Disabling or killing a target does not take a considerable amount of time for this technology. However, the defense drones are easily susceptible to Goa'uld weaponry including zat'nik'tels and staff weapons.
