Detection Systems
Sentinor’s detection systems provide intrusion detection and perimeter protection for fences, barriers, tanks, ground areas and fixed structures across critical national infrastructure. Designed to identify genuine attack activity, the systems deliver reliable early warning while maintaining low false alarm rates.
Fully compatible with Enhanced+ and Uni IO alarm analysers, Sentinor detection systems integrate directly into the wider alarm architecture, supporting advanced alarm processing and optional audio or thermal image verification. Proven in harsh and high‑risk environments, they provide operators with clear, actionable information to support effective response to real‑world intrusion events.
FenceWeb
Advanced perimeter intrusion detection for fences and barriers
FenceWeb is Sentinor’s vibration‑sensitive intrusion detection sensor, engineered to provide high‑performance perimeter protection for critical national infrastructure sites. Designed for installation on fences, barriers and other perimeter structures, FenceWeb delivers reliable, early‑warning detection of cutting, climbing and tampering attempts while maintaining an exceptionally low false‑alarm rate.
At the heart of the system is Sentinor’s advanced FenceWeb sensor cable — a highly versatile, easy‑to‑install sensing cable selected and engineered for maximum detection capability across a wide range of fence types. The cable is supplied in continuous lengths of up to 1500 metres, allowing fast, flexible deployment along extensive perimeter lines.
FenceWeb integrates directly with our Enhanced+ alarm analyser, enabling precise alarm processing. When paired with an Enhanced+ analyser, it also provides attack verification via audio, giving operators clear insight during intrusion attempts. It can additionally be connected to other hardwired analysers or integrated into third‑party security systems for enhanced situational awareness and layered perimeter defence.
Robust, proven and designed for high‑risk environments, FenceWeb is a dependable solution for organisations that require strong, resilient perimeter protection with consistent, accurate performance

TankWeb
Intrusion detection for tanks and fixed infrastructure
TankWeb is Sentinor’s advanced intrusion detection system engineered to protect above‑ground tanks and other similar types of fixed infrastructure. TankWeb provides reliable, high‑assurance detection for critical assets.
The system uses a two‑part detection approach, a passive seismic sensing cable mounted directly to the structure, and an acoustic sensor module that processes and verifies attack signatures. If the sensing cable is cut, damaged or impacted, TankWeb immediately triggers a tamper alarm, ensuring dependable early warning against intrusion attempts.
Although designed for potable water tanks, TankWeb is highly versatile and can be deployed across any fixed infrastructure requiring resilient, unobtrusive protection. It is installed using non‑destructive fixing methods, allowing it to be fitted cleanly to existing assets without structural modification.
TankWeb integrates directly with Sentinors Enhanced+ and Uni IO analysers, supporting precise alarm processing and offering optional audio and image verification through the Enhanced+ platform for added situational awareness.
Robust, discreet and engineered for demanding environments, TankWeb delivers trusted, field‑proven protection for tanks, reservoirs and fixed infrastructure where failure is not an option.

VibraWeb
Vibration‑based intrusion detection for fixed infrastructure
VibraWeb is a versatile, vibration‑sensing intrusion detection system designed to protect liquid storage tanks and other large fixed structures where traditional cabling methods, such as TankWeb, cannot be installed. Using a network of magnetic sensors mounted unobtrusively around a structure, VibraWeb continuously monitors for vibration signatures associated with interference, tampering and physical attack.
Engineered for environments where access is restricted or surface modification is not possible—such as steel roofs or elevated tank structures—VibraWeb provides a practical, non‑invasive solution without compromising detection performance. Its magnetic mounting method allows sensors to be installed rapidly, safely and without any structural drilling or alteration, making it ideal for both new and existing infrastructure.
VibraWeb interfaces with alarm analysers as a standard sensor input, enabling full use of advanced alarm analysis, configurable detection thresholds, event logging and all available communication paths. When integrated into an Enhanced+ system, alarms can be delivered directly to FlightDesk, providing operators with immediate visibility and actionable intelligence during intrusion events.
Simple to install, robust in operation and designed specifically for challenging industrial environments, VibraWeb offers reliable structural attack detection wherever TankWeb installation isn’t possible, ensuring critical infrastructure remains protected at all times.

Thermal Snapshot Camera
Thermal snapshot imaging for detection and intrusion verification
Sentinor’s Thermal Snapshot Camera provides fast, reliable visual verification for critical infrastructure sites, working seamlessly alongside the Enhanced+ alarm analyser to deliver both motion detection and clear thermal imagery during intrusion events.
Using a defined detection zone, the camera automatically captures thermal snapshot images whenever movement is detected — and also when an access point is attacked or tampered with. On trigger, the Enhanced+ analyser instantly collects images and transmits them with the alarm event over IP, giving control room operators visual context so they can assess the situation and respond with confidence.
To ensure maximum cyber security, all cameras operate on a fully isolated camera network, completely separate from the Enhanced+ IP network. This separation ensures the camera system remains locked down, secure, and protected against cyber intrusion attempts.
Thermal imaging technology is used to keep image files compact and quick to transmit, while still offering clear two‑tone visuals that make identifying intruders straightforward — even in darkness, poor weather or visually complex environments.
Purpose‑built for CNI protection, the Thermal Snapshot Camera delivers dependable detection, rapid visual verification and robust cyber security, giving operators the crucial insight needed to respond appropriately to real‑world threats.
