In modern investigations, time and accuracy are everything. That’s why at Semantics 21 (S21), we’ve spent over a decade pioneering media review technology – and now, we’re proud to introduce our latest innovation: S21 CCTV.
Developed in direct response to the needs of law enforcement agencies across the globe, S21 CCTV is changing how investigators process CCTV, bodycam, dashcam and mobile footage – faster, smarter and with greater accuracy than ever before.
We’re not new to this – hundreds of agencies around the world rely on us daily. We’re proud to be multi-award-winning, including recipients of the 2019 Queen’s Award for Enterprise and the 2024 King’s Award for Enterprise – two of the UK’s highest honours, recognising the transformational impact our innovations have had on policing, safeguarding, and justice.

Built With Investigators, For Investigators
S21 CCTV is more than just video playback. It’s a complete, AI-powered review solution that helps investigators find what matters – fast. You maybe familiar with tools like Amped Five or Brief Cam; we’re the alternative.
It includes as standard:
- AI-assisted detection of people, vehicles, number plates, and on-screen text (OCR)
- Unmatched video enhancement tools: deblur, recolour, super resolution, shadow removal, and our exclusive anti-shake stabilisation for fast-moving bodycam footage
- Automatic redaction of all but target faces for safeguarding and GDPR-ready exports
- Broad codec support, fully offline operation, and built-in help – no steep learning curves or servers required
Designed to work with standard police hardware, S21 CCTV is as powerful as it is practical – simple to use, affordable to deploy, and made for operational reality.
Proven in the Field
This isn’t just theory – it’s delivering results every day.
✅ During the recent UK riots, we provided S21 CCTV free of charge to help safeguard frontline officers and the public. One standout case – the Police Service of Northern Ireland (PSNI) – had originally budgeted two years to review footage. With S21 CCTV, they completed their investigation in just a few weeks.
✅ In a major international murder investigation, officers spent six weeks manually reviewing CCTV to find a white van. It was missed repeatedly – until S21 CCTV located it in seconds. The van was visible for just three seconds, turning a corner. That discovery played a vital role in securing a successful conviction.
S21 CCTV is already supporting investigations into missing persons, gang violence, human trafficking, riot disorder, homicide and more.

Let S21 CCTV do the hard work, so you can focus on what you do best – catching perpetrators, rescuing victims, and protecting the public.
You Don’t Have to Take Our Word For It
Let’s be honest – marketing can sometimes feel like snake oil. That’s why we don’t expect you to rely on ours.
Our customers believe so strongly in our ethics, service, and software that they’re happy to speak with you directly about working with S21 and using S21 CCTV. So, if you’d rather hear it from a trusted peer than a polished pitch – just ask. We’ll connect you.
Until Now, Word of Mouth Was Enough
To date, every single customer has come to us through word of mouth – a testament to the trust we’ve earned and the results we deliver. But as we grow, we know this tool is too revolutionary to stay quiet.
S21 CCTV is already transforming investigations – and we want every force, every unit, and every officer who needs it to benefit from it.
