What is LIMA’s DMVS?

DMVS is a unique and patented solution which allows two-way video communications into police cells.

It provides a way for Inspectors, Detention Officers and the wider support team around Criminal Justice to communicate effectively with arrested individuals, driving down operational costs and improving the speed of the judicial process.

The Technology

DMVS operates on an open source Extensible Messaging and Mobile Presence Protocol (XMPP) platform which can be viewed on all of your existing video-enabled devices. This open source technology feeds into the Government's Digital Strategy which, in turn, allows the DMVS to be sold via the G Cloud Framework.

The Unified Communications services are integrated into a web-based platform that delivers voice and video communication, instant messaging, conferencing and desktop sharing.

The unique fixed panels within each cell comply with MOJ Estates Directorate Technical Standards and are built by fabricators with over 25 years of experience within custody environments.

LIMA delivers, installs and fully supports the system from end-to-end.

Advantages of the system include:

  • Safeguarding detainees and providing a better experience through reduced waiting time

  • Enabling Inspectors to conduct PACE reviews within cells from anywhere in the estate resulting in reduced footfall at custody sites

  • Reduction in time escorting booked-in detainees allowing time to be utilised elsewhere, increasing the productivity of custody staff

  • Offline screen can be used to display vetted video messaging and Police Force marketing campaigns and streams through Crimestoppers, the Behavioural Insights Team etc.


LIMA leading with innovation

With police forces responsible for shaping their own digital transformation, there remains an emphasis on the implementation of technology to streamline processes and improve efficiencies. Following the changes to Code C of section 40A of the Police and Criminal Evidence Act 1984 (PACE) there is now scope for the use of telephone and video reviews of detention and video links for other custody decisions.

Who has DMVS been designed for?

Who has DMVS been designed for?

Prior to the design and licensing work carried out by LIMA to enable the screens and video cameras to be installed in the cells behind our wall mounted panels, the use of this technology had never been available. PACE reviews, duty solicitor calls and interpreter services previously needed to be carried out in person increasing costs and introducing delays into the allowed custody period.

Savings in time and money are returned immediately to the force. 

DMVS is the result of extensive consultation with the UK wide Criminal Justice leading authorities, including Chief Constables and Judges. We have invaluable knowledge and are a leading innovator in this field, having delivered the first and only in cell point to point video in the world to three police forces simultaneously and carrying the only Ministry of Justice Estates approval to design and fit the screens in cells.

Looking to the future, we are pushing the innovation further by integrating with HM Courts.
