MAVAS™ is Handy AV’s intelligent safety and compliance platform, designed to help organisations meet Martyn’s Law requirements with speed, clarity and control.
It unifies audio, visual, and emergency technology to streamline emergency response and safeguard every person on site through centralised AV control.

MAVAS™ stands for Mass Audio Visual Alerting System, a cloud based system providing a dashboard to manage your enterprise.
Our system coordinates all alerting to trigger messaging to desktop displays, mobile phone, SMS, voice announcements and digital signage. It also controls feeds from CCTV to give reactive reponse to incident locations and controlled access to areas for evacuation, invacuation and controlled escape.
This is achieved by integrating Access Control, SMS, PA/VA systems, Digital SIgnage, CCTV monitoring and triggering, all managed locally on-site via our EDGE Server. Our systems can be configured to be as simple, or as complex as required.

Handy AV was established in 2002, as a specialist in Digital Signage and Digital Experientials, developing interactive experiences and systems integration knowledge, providing solutions for brands around the world.
We have been developing now for nearly 25 years. As a leading systems integrator we have lead the way with new technology, developing touch screens for use by brands such as Adidas & Motorola, Cinemas, Estate Agents, Museums and Retail. Always looking for new technology and how to integrate.
MAVAS™ represents the best of our knowledge and is our legacy to prevent harm and help save lives.

MAVAS™ operates as a cloud-based command platform that connects directly to on-site media players and amplifiers located in defined zones across your premises.
When an emergency alert is triggered, the MAVAS™ API pushes messages to the local EDGE server. From there, zonal content is activated, instantly displaying emergency messaging on digital signage screens and broadcasting alerts through the integrated audio system. This is also extended to mobile phones and connect PC screens, tablets, etc.
This real-time, synchronised communication ensures that every area receives the right information at the right time — maximising safety and compliance. Typically alerts can be displayed within 1 second.


The cloud-based content management backbone of MAVAS™, Blue River™ delivers centralised control and instant distribution of visual alerts across all connected digital signage displays, ensuring consistency, speed, and reliability during critical events.

Connected digital signage displays automatically switch to emergency overlays during incidents, providing clear, location-specific instructions. From evacuation routes to safety notices, messaging is consistent and impossible to miss.

Real-time visibility from on-site personnel equipped with body cameras provides live situational awareness. Integrated directly into the MAVAS™ platform, body cam feeds help security teams assess, respond, and coordinate actions with precision.

Our intelligent access control system, HandyCHECKPOINT™, integrates seamlessly with MAVAS™ to secure entry points, trigger lockdowns, and monitor movement across your site, ensuring controlled, compliant safety management.

With MAVAS™ mobile integration, key personnel can trigger or receive alerts directly from their smartphones. The app provides instant communication and remote control, empowering teams to act fast, wherever they are.

MAVAS™ can instantly override desktop displays with emergency alerts, ensuring critical information reaches staff across office or back-of-house environments, even if they’re not near a screen or speaker system.

MAVAS™ gives operators granular control over every zone. From isolating incidents to managing site-wide announcements, the platform ensures that communication is precise, targeted, and effective across every area.

Integrated audio systems broadcast synchronised voice alerts and tones across defined zones. Whether indoors or outdoors, messages remain clear and consistent, ensuring everyone hears what they need to stay safe.
