Perimeter and site security monitoring for critical infrastructure, telecoms compounds, utilities, depots and remote estates, using fence breach detection, PIR, piezoelectric sensing, low-power telemetry and immediate alert routing.
IoT Technologies builds perimeter monitoring around real incidents: fence breaches, motion events, gate changes, tamper, vibration, forced access and suspicious activity that needs a fast, evidence-backed response.
Real-time perimeter intelligence
Use vibration, piezoelectric sensing, contact, tilt and zone logic to detect fence-line events and boundary changes.
Monitor restricted zones, approaches, gates and compound interiors for activity that requires attention or escalation.
Use low-power RF for long-life sensors where Wi-Fi and cabled infrastructure are impractical or unavailable.
Create timelines, alert trails and acknowledgement records that support investigations, insurers and operational assurance.
Perimeter security is not just cameras and patrols. It is the ability to detect a meaningful event quickly, classify it with enough confidence and trigger a response before damage, theft or disruption escalates.
Critical sites fail at the edges. Fences are cut, gates are forced, cabinets are opened, cable routes are disturbed, compounds are entered out of hours, and remote assets are targeted because attendance is slow and evidence is weak. Traditional security often leaves teams with either too much footage or too little context. Perimeter monitoring should create priority: a small number of high-quality signals that show where the event happened, what changed and how urgent it is.
IoT Technologies designs site security around layered sensing. Fence breach detection, PIR motion, piezoelectric fence sensing, vibration, tilt, magnetic contacts, cabinet tamper, gate status, acoustic indicators and asset-level sensors can all contribute to a clearer event picture. The point is not to install every sensor everywhere. The point is to place the right sensors at the attack paths, access points and vulnerable zones where response time and evidence matter.
433 MHz telemetry can be highly practical for perimeter and compound security when the site is surveyed correctly. Many UK infrastructure locations have weak Wi-Fi, no convenient power, awkward structures, metalwork, cabinets, remote fence lines and exposed outdoor positions. Low-power 433 MHz devices can report breach, tamper, contact, vibration and motion events from battery-operated sensors without requiring local IP networking at every point. It still needs RF planning, antenna positioning, range checks and interference review, but it gives a strong route for long-life field sensing.
False-alarm control matters. A fence vibration event caused by wind is not the same as a repeated cut pattern. PIR motion at the wrong time is different from expected authorised access. Piezoelectric sensing, vibration thresholds, timing windows, zone correlation, gateway evidence and acknowledgement workflows help distinguish background noise from response-worthy events. The system should reduce noise and increase confidence, not create another dashboard nobody trusts.
For critical infrastructure, the response chain is as important as the sensor. A high-severity perimeter breach may need immediate notification, escalation to on-call teams, security contractor dispatch, camera review, internal incident logging or evidence preservation. A lower-severity event may need watch status or maintenance follow-up. The platform should route events based on site, zone, severity and operational responsibility.
Dashboards must show action, not theatre. Operations teams need to see site state, active events, affected zones, acknowledgement status, last contact, device battery, gateway health and event timelines. Management teams need portfolio visibility across sites, regions and suppliers. Investigators need a defensible record that shows what happened, when it happened, who was alerted and how the response unfolded.
This page describes monitoring and operational security support. It does not guarantee prevention of intrusion, theft, sabotage or damage, and it does not replace physical security assessment, certified alarm systems, guarding, policing or statutory obligations. Its value is in strengthening early detection, response discipline and evidence across hard-to-monitor sites.
Fence breach
Fence vibration, piezoelectric sensing, cut-pattern detection, tilt and contact events can help identify perimeter interference before an incident reaches cabinets, compounds or high-value assets.
PIR and motion
PIR and motion sensors can watch gates, approaches, internal compound zones, cabinets and blind spots where cameras alone do not create enough priority or context for response.
433 MHz telemetry
433 MHz low-power telemetry can support battery-operated security sensors across fence lines, compounds and remote infrastructure. We survey range, interference, antenna position and gateway placement before scaling.
Tamper and access
Magnetic contacts, enclosure tamper, vibration, accelerometer and access-state signals can create early warning when assets or secure spaces are opened, moved or disturbed.
Dashboards and escalation
Intelligent dashboards show live site status, event severity, affected zones, acknowledgement, device health and response history so security teams can act quickly without chasing raw telemetry.
Critical infrastructure
Telecoms compounds, utilities, energy sites, water infrastructure, remote cabinets, depots and critical estates need consistent event visibility across locations that are costly to patrol and hard to monitor manually.
Deployment approach
A strong perimeter deployment starts with the boundary, the attack paths, the response owners and the evidence requirement.
We map the site, identify vulnerable zones, survey RF behaviour, select the right sensor mix, tune event thresholds, prove alert confidence and then scale the model across compounds, corridors, regions or national estates.
Define assets, boundaries, breach scenarios, vulnerable zones, response owners, escalation paths and evidence requirements.
Define risk
Assess fence lines, gates, cabinets, power, mounting, 433 MHz coverage, gateway placement, interference and site access.
Confirm site
Set sensor thresholds, correlation rules, alert severity, notification routing, acknowledgement and dashboard views.
Tune events
Run controlled breach, motion, tamper and access tests to validate event quality, false-alarm handling and response workflow.
Evidence test
Roll the proven pattern into more zones, sites and regions with consistent reporting, device health and support routines.
Estate rollout
Bring the site type, perimeter layout, security risks, response workflow and evidence needs. We will shape a pilot around the incidents you actually need to detect.

Provide early warning and event evidence for compounds, substations, water assets, plant areas and hard-to-patrol locations.
Use piezoelectric, vibration, tilt and contact sensing to detect boundary interference and route alerts by zone and severity.
Track forced access, door state, tamper, impact and abnormal access patterns across exposed assets and secure spaces.
Create real-time security visibility where local attendance is limited, connectivity is weak and response depends on accurate event context.
Standardise perimeter alerting, dashboards and evidence across sites that protect nationally important services and operational continuity.
FAQ
It is low-power sensing across fences, gates, buildings and compounds that turns breaches, motion events, tamper and forced access into immediate alerts, with a timestamped evidence record behind every incident.
Piezoelectric and vibration sensing on the fence line registers cutting, climbing and impact signatures, separating genuine breach activity from wind and environmental noise before an alert is raised.
Yes. Sensors are battery-powered and use sub-GHz radio at 433 MHz and 868 MHz, which suits compounds, depots and remote estates where conventional connectivity is poor or absent.
Alerts are routed to the people and processes you already run — control rooms, key holders, mobile response — with escalation rules and a clear event timeline for review after the incident.
No. It complements existing security measures by covering the gaps between them, giving earlier warning of physical interference and producing evidence that supports response and post-incident review.
