When a property becomes vacant or vulnerable, the risks increase immediately. Unauthorised access, vandalism, theft and fire can all result in costly damage, project delays and insurance complications if a site is left unprotected.
Marpol Security provides fully managed temporary alarm systems that can be deployed within hours, even where there is no existing power or cabling. By combining external threat detection, internal intruder protection, 24/7 monitoring, and rapid response, we provide complete protection from a single trusted security provider.

Every site presents different security challenges. Some require external perimeter protection to detect intruders before they reach the building. Others need internal protection to secure vulnerable areas inside the property. Many benefit from both.
Our temporary alarm systems can be deployed individually or as a fully integrated solution, allowing us to tailor protection to your site, risk level, and operational requirements.
Installing an alarm is only one part of protecting a vacant property. Effective security depends on fast deployment, professional monitoring and the ability to respond immediately when an incident occurs. Marpol Security provides a complete managed service from initial site assessment through to installation, monitoring and response. You deal with one experienced security company throughout, giving you a fully accountable solution backed by our in-house 24/7 control room and response teams.
