Overview

Built for the reality of CCTV investigations

Modern investigations increasingly rely on video evidence, yet reviewing CCTV remains one of the most time-consuming parts of an investigation.

Investigators regularly face hours of footage, fragmented formats, poor image quality, and limited tools for finding the moment that matters. S21 CCTV is a specialist investigative platform designed to accelerate the review of CCTV, body-worn, and digital video evidence. AI-assisted detection helps surface people, vehicles, objects, and movement across large volumes of footage, allowing investigators to focus on relevant activity rather than manually scanning timelines.

Investigators can enhance footage, tag evidence, redact sensitive material, and produce court-ready exports within a single investigative workflow. Because S21 CCTV operates fully offline, it can be deployed in secure investigative environments without exposing sensitive cloud services or external systems. S21 CCTV exists to make video evidence usable, not just viewable.
The problem

CCTV review is still too slow, too manual and too easy to miss

Investigators are often faced with hours of footage, poor image quality, fragmented formats and limited tools for finding the moment that matters. S21 CCTV is built for time-critical investigations where teams need to understand what footage shows, not just play it back.
Faster, clearer, sharper

What S21 CCTV helps investigators do

Review footage faster

Visual grid and timeline navigation help investigators scan large volumes of video and isolate moments for deeper review.

Find movement, people, vehicles and objects

AI-assisted detection helps surface activity across footage so investigators can focus attention on relevant events.

Analyse motion, audio, text and plates where applicable

Supports motion review, audio review, OCR and ANPR-style workflows where applicable.

Enhance poor-quality footage

Tools support clearer review through improvements to lighting, contrast, sharpness and visibility.

Redact, tag and report

Investigators can tag evidence, redact sensitive material and prepare outputs for disclosure, review and reporting.

S21 CCTV Features

All-in-One AI CCTV review software

The software supports a wide range of formats including CCTV, bodycam, dash cam, mobile video, and other sources using common video codecs, as well as several proprietary and fragmented formats used in investigative work. With built-in audit trails and exportable reports, S21 CCTV makes video analysis fast, powerful, and court-ready.

Quickly Review CCTV Footage with Grid-Based Video Navigation

Slide through video thumbnails in a visual grid layout to rapidly scan hours of CCTV or DVR footage. Quickly isolate clips of interest before committing to deeper analysis, streamlining your review workflow.

Automatically Detect and Highlight People in CCTV Evidence

Use AI to automatically detect individuals in footage — even when faces are obscured. Easily highlight and track people across frames using advanced person detection trained on real-world forensic datasets.

AI Vehicle Detection by Type and Colour

Instantly detect and isolate vehicles in your video evidence — including cars, lorries, buses, bikes, and more. Filter by type or colour to quickly locate relevant vehicle movements in traffic-heavy scenes.

Targeted Motion and Audio Detection for Forensic Video Review

Draw a region on screen to detect motion in specific areas, or use audio analysis to detect sound events within CCTV or mobile footage. Ideal for identifying activity during silent or low-visibility scenes.

Automatically Redact Faces or Reveal Only the Target Individual

Use AI to detect and blur all visible faces in your footage instantly — or isolate and keep one or more specific subjects visible. Ideal for redacting bystanders, safeguarding victims, or preparing footage for public release and legal disclosure. Fully auditable and frame-accurate.

AI-Powered Video Enhancement Tools including Facial Upscale.

Enhance video and image evidence with AI: improve colour, contrast, and lighting; remove glare or shadows; sharpen blurry footage; deblur vehicle plates; upscale low-resolution faces; recolour greyscale footage; and restore detail in compressed or degraded files.
How it works

From hours of footage to focused review

S21 CCTV helps investigators move quickly from raw video evidence to focused review.

Teams can import footage from multiple sources, scan and filter it for relevant activity, inspect key moments in detail, and prepare tagged, enhanced or redacted outputs for reporting and disclosure.

Import video evidence

 CCTV, DVR, body-worn, dashcam, mobile footage and other common video sources.

Scan and filter footage

Use grid review, motion detection, audio events and AI-assisted detection to narrow the material.

Inspect the relevant moments

Use grid review, motion detection, audio events and AI-assisted detection to narrow the material.

Prepare outputs

Tag frames, redact sensitive content and generate review-ready or disclosure-ready exports.

How investigators use S21 CCTV to turn video evidence into usable intelligence

S21 CCTV helps investigators review, enhance, and analyse video evidence faster, supporting motion, audio, object, OCR, and ANPR-style workflows where applicable. It is built for time-critical investigations where teams need to understand what the footage shows, not just play it back.
