A prison perimeter is two different problems in one site: where on the fence, and what is in the sally port. RBtec answers both with zoned fence detection and volumetric LiDAR, reporting into the control room officers already staff.

Prison security systems have to stop three different events. Escapes over or through the dual fence lines, where seconds and an exact location decide the outcome. Contraband coming the other way: throw overs at the fence and, increasingly, drone drops into the yard. And the quiet structural problem behind both: tower posts that no longer have officers in them, as agencies replace static staffing with technology. Every one of these depends on detection the control room can trust, which is why nuisance alarm rate is the specification correctional buyers weigh hardest.
ACA accreditation carries performance based standards for adult institutions that include perimeter security expectations, and state departments of correction publish design standards that typically mandate perimeter intrusion detection on medium and maximum custody facilities. Federal facilities follow BOP specifications. Procurement is public bid, so systems that document their detection zones, alarm handling and maintenance cleanly have an advantage on paper as well as on the fence.
The dual fence lines take zoned sensing, so an attempt is reported with the zone and fence line, and response teams go to a place, not a sound. The sally port and vehicle gate take PulseVi 3D LiDAR, which watches volume rather than fabric: a person hiding where only a vehicle should be is exactly the event it exists for, and darkness does not change how it works. Walls and rooflines take WallAlert structural sensing, and the ground between fences can carry covert buried detection for digging and crawling attempts.
With tuning, not promises. Razor wire sings in wind and birds land on everything, so each zone carries its own sensitivity profile and the algorithms separate environmental noise from cutting and climbing. Detection is layered so the failure of officer trust that killed older systems, alarms nobody believes, does not repeat.
