Marpol Sentry is an autonomous intrusion detection system designed to provide immediate security for vulnerable and temporary sites.

Contact our 24/7 Control Room to discuss your security requirements. We’ll arrange a free site visit and recommend the most appropriate deployment for your premises.

A Marpol Security specialist carries out a comprehensive assessment of your site, identifying vulnerable areas and determining the most effective location for the Marpol Sentry unit.

Marpol Sentry is designed for fast installation, allowing protection to be established quickly with minimal disruption to your site or project.

If suspicious activity is detected, alerts are verified through AI and our 24/7 Control Room before the appropriate response is coordinated. Where required, Mobile Response Officers or the emergency services can be deployed.
Powered by battery and solar technology, it can be deployed quickly without relying on permanent infrastructure, making it ideal for construction sites, vacant properties, open land and other locations requiring fast, effective protection.
Combining intelligent detection, high-definition cameras, and 24/7 monitoring, Marpol Sentry helps identify genuine threats quickly and supports a rapid response when intervention is required.
When Marpol Sentry detects suspicious activity, intelligent sensors and high-definition cameras work together to verify the threat before an alert is generated. This helps reduce unnecessary activations while ensuring genuine security incidents receive an immediate response.
A built-in audible alarm also acts as a strong visual and audible deterrent, encouraging intruders to leave the site while additional support is coordinated.
