Precision Microwave Perimeter Intrusion Detection

Vigil raises the standards for cost effective Perimeter Intrusion Detection Systems, bringing a new level of intelligence to intruder detection.

Vigil uses advanced signal processing and on-board analytics to deliver accurate intruder detection in challenging environmental conditions.

The Alert Zone can be up to 200m in length for each link, 10m in height and as narrow as 1m in width at optimal deployment.

VIGIL continuously analyses transmitted microwave signals using a variety of adaptive Digital Signalling Processing (DSP) techniques that reduce nuisance alarms, narrow the Active alarm zone and adapt to environmental changes.

Adapts to Environmental change

On installation the system examines the environment and self-calibrates to account for factors such as standing water, foliage, vegetation or weather conditions.

By continuously monitoring the signal any subsequent changes caused by rain, snow, and other weather conditions are considered and the system adapts to provide constant vigilance.

Future Proof

All VIGIL systems can be upgraded remotely, benefitting from future advances in Sensurity’s algorithm development.

Narrow Footprint

VIGIL can be installed along roadsides, hedge rows and close to fence lines due to it’s ”Narrow Active Alarm Zone” created by the DSP techniques employed and a proprietary antenna design.

VIGIL offers the lowest cost of system installation in its class, requiring a reduced deployed footprint and minimal maintenance.

Overlapping Footprint

To provide 100% coverage, competing systems advise that sensor beams should be overlapped. This creates a large installation footprint and can double the amount of mounting and cabling materials required.  Vigil has one of the smallest overlapping installation footprints available.

One Cable – Power Over Ethernet

VIGIL nodes have been optimised to ensure the lowest possible power consumption. Nodes can be powered using POE (Power over Ethernet) meaning that each node may be operated with only one cable to provide power and data transfer.

Communications via VIGIL are based on the Open Supervised Device Protocol (OSDP) which is readily used by access control systems.

Reducing the cost of ownership

Minimal Nuisance Call Outs

VIGIL ensures that the nuisance alarm rate and associated man power is kept as low as possible. Intelligent DSP ensures that problematic triggers such as wildlife and environmental factors reduce the number of nuisance alarms.

Remote Configuration and Maintenance

VIGIL may be configured and maintained remotely by the installer using dedicated Control software.

Install using existing infrastructure

VIGIL is equipped to work using existing infrastructure. The system supports RS485, relay integration and CAT 5/6.


Vigil offers the lowest cost of system installation in its class, requiring the smallest deployed footprint and minimal maintenance.

Open Integration – OSDP – Secure

Vigil communicates using the “OPEN SUPERVISED DEVICE PROTOCOL” (OSDP- Secure). The protocol was developed by the Security Industry Association’s Access Control & Identity Group, with an aim to foster interoperability between security devices.


Each node contains an accelerometer and an optical tamper switch. Any attempt to physically interfere with a node will trigger an alarm.

Anti – Spoofing

Vigil is impervious to spoofing and “Man In The Middle” attacks. The system operates a poling protocol that demands all packets are signed with a public key. Any attempt to spoof the system will result in an alarm trigger.


VIGIL is hardened to operate in tough environments. Weather proof, temperature tolerant, and vandal resistant, VIGIL is continuously and rigorously tested to comply with the toughest Certified Standards.

Vandal Resistant

VIGIL nodes are made from impact resistant polycarbonate and shatter proof nylon, they are supplied with stainless steel fixings.

Temperature Tested

VIGIL operates between -40 and 65 degrees Celsius.

Weather Proof

VIGIL nodes are approved to an IP65 standard meaning they are impervious to dust and water ingress.


VIGIL has attained the toughest approval, it is CE approved for EMC and R&TTE and has also achieved EN50130-4 Alarm System Standard.
