What our clients say about us

Neil Dawson
Forensic Technician, Police Scotland

During an on going major investigation our team were tasked with gathering CCTV evidence from an unbranded DVR that had an unknown password. After several failed attempts to locate the required information to allow access to the DVR contact was made with Demux Video Services Ltd, regarding DME Forensics, DVR Examiner.

Within 48hrs from point of order we received the product; this allowed us immediate access to the required CCTV Footage by extracting the data direct from the DVR’s HDD.

Without Demux Video Services Ltd and DME’s DVR Examiner we would have faced lengthily delays and may even have been unable to retrieve the evidence that we required.

Phil Booth
Major Incident Media Officer, Lancashire Constabulary

I can confidently say that CaseGuard stands out as one of the best redaction tools on the market. Its easy-to-use interface coupled with powerful AI features makes the redaction process seamless and efficient.

CaseGuard has greatly assisted us with blurring faces, removing sensitive information and following individuals in crowds, CaseGuard handles it all with precision and speed.  We have used it for a wide range of jobs, these include CCTV of football disorder offences in which there are large groups of offenders that need highlighting and tracking, to body cam footage of domestic violence offences where individuals within a property need their faces redacting. CaseGuard has never failed to deliver exceptional results.

Thanks to CaseGuard, we can confidently redact videos, knowing that sensitive information is protected without compromising on quality. It’s a must-have tool for any organisation serious about video redaction.

Demux facilitated the purchase of CaseGuard very professionally.  They were extremely helpful with setting up a product demonstration with CaseGuard, and they also were very accommodating, providing us with a trial of the software.

Purchasing CaseGuard through Demux was great as they supported us every step of the way.

Mark Brown
Digital Media Supervisor, Lancashire Constabulary

Thanks again for the very efficient service you offer. You are by far one of the easiest forensic companies to deal with, which is very refreshing and much appreciated. DVR Examiner has been a great tool for us over the past year.

I have recently been asked by our Divisional Commander to produce a report on the efficiency savings it is givingus as a force. We look forward to using it for another year.
