Security Devices

E-Noses can be used in many security and safety contexts, where airborne chemicals are a signal of something requiring urgent attention. Likely scenarios are safety in planes, trains and buses where timely detection of oil fumes or overheating wiring will save lives. In other situations, on production lines or in fume ducts and pipelines, E-Nose sentinels will continuously monitor for leaks or unwanted events, and alert the management.

Graffiti vandalism is costing State and Local Governments many millions of dollars a year. Market studies have shown that people feel unsafe in areas with graffiti, and fewer passengers will use public transport which has graffiti on and inside its vehicles and on stations and infrastructure.

The Mk4 E-Nose has been proved to be an effective graffiti paint detector. In a recent field study with a large rail corporation, the E-Nose distinguished between spray paint and solvent and could detect paint being used at a distance of 45 metres. E-Noses deployed in rail carriages will be a new and important deterrent and cost saving measure.

 Our devices consist of arrays of robust and fast acting chemical sensors, supplemented by novel patented electronics and software. Chemicals in the air are detected by the sensor arrays, registering complex odour “images” in real time.
A permanent record is sent to your computer via line or wireless connection, where it is identified, quantified and alarms for abnormal events. 

 "Thank you e-nose for eradicating graffiti from our Scout Hall. It has been three years since you first installed the device and after some arrests it appears that the word is out that the hall is a "No Go" zone. We have remained graffiti free for the last year even without the e-nose installed. This is a major turnaround to the weekly attacks we were getting a few years ago. Thank you e-nose team we couldn't have done it without you!"
