Forensic video enhancement software is specialist software that improves the clarity of video and image evidence so investigators can see detail that would otherwise be unusable, while keeping every change forensically sound and fully auditable.
S21 CCTV is an AI-powered, all-in-one platform for reviewing, analysing and enhancing CCTV, DVR and digital video evidence. No additional hardware or third-party plugins are required, and no prior forensic training is needed to get started.
Its enhancement tools reveal detail through colour correction, deblurring, upscaling and light balancing, recover frames from partially corrupted video files, and let investigators annotate, blur, watermark or crop clips for disclosure. Because S21 CCTV operates fully offline, it can be deployed in secure investigative environments without exposing sensitive cloud services or external systems.
Modern investigations increasingly rely on video evidence, yet reviewing CCTV remains one of the most time-consuming parts of an investigation. Investigators are often faced with hours of footage, poor image quality, fragmented formats and limited tools for finding the moment that matters.
A number plate that cannot be read, a face that is too compressed to identify, a clip that will not play because the file is partially corrupt: each of these can stall a case that otherwise has everything it needs. S21 CCTV is built for time-critical investigations where teams need to understand what footage shows, not just play it back.
Enhance distorted, blurred or compressed video and image files so that detail becomes visible and usable for review.
Reveal detail through colour correction, deblurring, upscaling and light balancing, without leaving the investigative workflow.
Recover frames from partially corrupted video files to reveal unseen content that would otherwise be written off as unplayable.
AI-powered video enhancement tools including facial upscale, so faces captured at low resolution can be brought up for closer examination.
Automatically redact faces, or reveal only the target individual, with selective control over who stays visible.
Maintain full control over processing and keep professional judgement in charge throughout.
Use specialist AI tools to enhance video evidence, including distorted, low-resolution or corrupt media, in a forensically sound and fully auditable environment.
Choose the right mode for the task. Frontline Mode offers fast, AI-free review with limited controls. Pro Mode unlocks full AI functionality and advanced features for deep forensic analysis.
That means a frontline officer can open a clip and get moving without training, while a specialist can take the same material into full forensic enhancement when the case calls for it.
Protect sensitive evidence and avoid the risks of cloud-based AI. S21 CCTV runs completely offline, ensuring no data leaves your environment and eliminating exposure to third-party access or breaches.
Deploy instantly without complex infrastructure. S21 CCTV runs efficiently on standard workstations or existing networked machines, with no dedicated servers or high-end hardware required.
S21 CCTV supports the analysis of footage from a wide range of devices, and it handles common video codecs alongside several proprietary and fragmented formats used in investigative work.
Enhancement rarely happens on its own. Investigators need to find the relevant clip before they can improve it, and they need to package it afterwards. S21 CCTV covers the whole path: import footage from multiple sources, scan and filter it for relevant activity using grid review, motion detection, audio events and AI-assisted detection, inspect key moments in detail, then prepare tagged, enhanced or redacted outputs for reporting and disclosure.
If your priority is finding the moment rather than sharpening it, the same platform is covered from that angle on our forensic video analysis software page.
No data leaves your environment, which removes exposure to third-party access or breaches.
Fast AI-free review for frontline officers, full AI functionality for deep forensic analysis.
Designed so any investigator can review video evidence, not just specialists.
