The IRONCLAD Fence Alarm System is a fence-mounted sensor cable system that detects intrusion attempts (cutting, climbing, or lifting) directly at the fence line.
Experience perimeter security that simply works with the IRONCLAD Fence Alarm System, a plug-and-play solution for reliable intrusion detection. Designed as a true plug-and-play system, the IRONCLAD eliminates the need for expensive training, certification, or special tools. Just install the sensor cable and the system self-calibrates to your fence immediately.
Unlike complicated alternatives, this armored fence alarm uses a proprietary algorithm with three layers of filtering to detect cutting, climbing, or lifting attempts while filtering out false alarms caused by wind, rain, and other weather conditions. It integrates seamlessly with your existing infrastructure, connecting via dry contact relays to any standard burglar alarm, DVR, or SCADA system you already own.
- Plug and play installation
- Detects cutting and climbing
- Maintenance free operation
- No Certification Needed
How Does the IRONCLAD Fence Alarm System Detect Intruders
The system uses three layers of false-alarm filtering.
1. The detection algorithm is designed to detect only sharp frequency vibrations associated with intrusion attempts, while filtering out the low frequencies caused by weather conditions.
2. Automatic real-time alarm threshold adjustment with wind rejection.
3. 500 sensitivity levels are easily adjusted to adapt the sensor sensitivity to the fence condition.
Fence Alarm System Sensor Layout:
The sensor cable comes pre-cut in 250 ft (75 m), 500 ft (152 m), or 1,000 ft (305 m) lengths.
Each LPU processor (analyzer) monitors up to two zones (two spools).
Each processor supports up to 2,000 ft (600 m) total, split across two zones of up to 1,000 ft (305 m) each.
Each kit includes an LPU processor in a weatherproof enclosure, plus the selected sensor cable length.
For larger perimeters, you can combine as many kits as needed.

Here are five reasons why security cameras are not enough (Even with Video Analytics!)
Cameras identify a human shape, but a sensor cable detects the physical act of climbing or cutting. One is a picture; the other is a confirmed breach
Heavy rain, dense fog, and snow can spoof even the best AI analytics. Detection does not depend on line of sight, so darkness, fog, glare and smoke do not affect it.
Intruders now use anti-AI clothing or simple masks to bypass facial and skeletal recognition. A sensor cable doesn't care what an intruder looks like, it only detects the physical force of the climb.
Video analytics are limited by "line of sight" and lighting. A sensor cable provides unbroken, 360° linear protection along your entire fence, eliminating the "dead zones" where AI loses track.
Modern analytics require expensive per-camera licenses and massive 4K cloud storage fees. The IRONCLAD system is a one-time hardware investment with zero recurring storage or licensing costs.
Unique features of the IRONCLAD system
Armored Sensor Design: The sensor cable includes a built-in steel mesh layer that provides heavy-duty physical protection without needing extra conduits.
Smart Weather Filtering: The system automatically ignores vibrations caused by wind, rain, or hail, ensuring that only real security threats trigger an alarm.
Easy Maintenance Boards: The processor uses a modular design with swappable internal boards, making it much faster and cheaper to repair or upgrade in the field.
Flexible Setup Options: You can adjust the system’s sensitivity directly on the device using buttons or use specialized software for more precise tuning.
Proven Durability: The system is built to last with a certified 80,000-hour reliability rating and a 10-year warranty on the sensing cable.
More Information About the IRONCLAD Fence Alarm System
A fence alarm system is a perimeter security system that detects intrusion attempts directly on the fence line.
Instead of waiting until an intruder reaches a building, storage area, substation, solar farm, airport, data center, or other protected asset, a fence alarm system provides early warning at the perimeter.
A fence-mounted intrusion detection system is designed to detect physical attacks on the fence, such as climbing, cutting, lifting, or jumping over. This makes the fence an active security layer instead of only a physical barrier.
IRONCLAD is a fence-mounted perimeter intrusion detection system that uses a sensor cable installed on the existing fence. The system detects fence vibrations caused by intrusion attempts and sends an alarm to the connected security system.
A fence alarm system is useful for sites that need outdoor asset protection, perimeter monitoring, and faster response before an intruder enters the protected area.

The IRONCLAD Fence Alarm System uses a vibration sensor cable mounted directly on the fence.
When someone cuts, climbs, lifts, or jumps over the fence, the sensor cable detects the vibration pattern created by the intrusion attempt. The processor analyzes the signal and activates an alarm when the activity matches intrusion behavior.
The IRONCLAD sensor cable is fully wrapped with stainless-steel braid for mechanical protection in outdoor fence installations. It is suitable for chain link fences, welded mesh fences, razor wire, and concertina coils.
Each IRONCLAD processor supports up to two detection zones. This allows a perimeter to be divided into smaller alarm areas, making it easier for security teams to identify the intrusion location and respond quickly.
IRONCLAD can be used as a standalone fence alarm system or integrated into a larger perimeter security system.
Outdoor perimeter security systems must detect real intrusion attempts while reducing nuisance alarms from wind, weather, animals, and normal fence movement.
IRONCLAD uses signal processing and adjustable sensitivity settings to help identify intrusion-related fence vibrations. The system is designed to reduce false alarms while maintaining reliable detection of cutting, climbing, lifting, and jumping attempts.
No sophisticated calibration is required. Installers can adjust the sensitivity of each zone on-site based on the fence type, fence condition, environment, and security level required.
This makes IRONCLAD a practical fence intrusion detection system for locations that need reliable outdoor detection without complex setup or constant maintenance.
IRONCLAD is used to protect fenced sites where early warning and perimeter intrusion detection are critical.
Common applications include utility substations, solar farms, data centers, airports, correctional facilities, industrial sites, commercial properties, equipment yards, construction machinery storage, RV and boat storage facilities, communication towers, cellular sites, border areas, and other high-security perimeters.
The system is installed on the existing fence line and is available in different sensor cable lengths. Larger sites can be protected by using multiple processors and dividing the perimeter into detection zones.
Gate kits are available for swing gates and sliding gates, allowing the fence alarm system to continue protecting access points.
Optional accessories include stainless steel twist ties, gate kits, and solar/wireless kit options for remote locations where power or communication infrastructure may be limited.
IRONCLAD integrates with alarm panels, CCTV systems, video management systems, NVRs, access control systems, sirens, lights, and other security equipment using dry-contact relay outputs. This allows the system to trigger cameras, alerts, notifications, or response actions when an intrusion is detected.
