Belsavis's automated security systems consist of a complex web of logic programs, identity databases, mechanical interfaces and emergency overrides. Computers control everything from coma gas ventilation to laser turrets to holocameras to energy field lockdowns, along with far more obscure technologies.
What makes Belsavis's security unusual is its distributed nature. Different sections of the prison and different types of responses are controlled by entirely separate computer systems. This ensures that damage or corruption to one system cannot compromise the entire prison, but it also makes untangling errors difficult at best.
Some of Belsavis's security systems are even tied into rumored alien technology in the deep levels of the prison; this allows them to access systems of unusual power, but also causes occasional eccentricities when outside protocols override modern programming. Usually, these eccentricities are harmless‒a computer displays its interface in an unknown language, or indoor humidity rises uncomfortably‒but the prison technicians fear that far worse is possible.
