Hardened perimeter security for correctional and government facilities.
A single physical fence is not enough to restrict escape attempts. Digging, tunneling, and climbing all remain viable options against a purely physical barrier, and correctional facilities need a way to eliminate these blind spots without relying on constant human patrol.
Underground tunneling attempts are invisible to fences, cameras, and other above-ground security measures.
A physical fence alone can be climbed, cut, or otherwise bypassed without an additional detection layer.
Birds and small animals near the perimeter can trigger unnecessary alarms in less selective systems.
Fog, rain, temperature swings, and wind can all degrade the performance of traditional detection systems.
InvisiFence uses underground seismic sensors to create an invisible fence around the facility perimeter, detecting intrusion on the ground or underground, making it impossible for inmates to jump over or dig beneath without triggering an alert.
Seismic sensors placed underground around the perimeter detect any unauthorized activity, whether on the surface or from a tunnel.
Self-learning algorithms classify each event, filtering out birds and small animals so genuine attempts are never lost in the noise.
A validated event immediately triggers an alarm to security personnel, whether the system is installed inside or outside the fence line.
A deep-learning algorithm continuously revises its baseline "normal" state as conditions change — a new patrol road or growing vegetation — without manual recalibration.
Seismic detection paired with AI camera verification reduces false alarms by over 90% compared to camera-only systems.
IP68 rated to MIL-STD-810G and operational from -40°C to 85°C, so detection performance holds steady through rain, wind, fog, and temperature swings.
Verified events route to security personnel in real time, with 18 dry-contact alarm outputs available for wiring into an existing alarm panel.
A continuous wired Sensor Cable covers a fixed perimeter, while wireless AIO XR sensors add coverage at individual buffer-zone points without trenching a full run.
Fully buried with no wires to cut or surface panels to defeat, and the above-ground PTZ camera carries a hardened IK10 vandal-proof casing.
For federal and state correctional facilities, Seismic Shield Pro's camera and recording hardware is NDAA compliant, meeting U.S. federal restrictions on surveillance equipment from prohibited manufacturers.
Installed inside the buffer zone or outside the existing fence line, InvisiFence adds a virtual layer of detection that catches tunneling and climbing attempts a physical fence alone would miss.
