Krishna Intelligence — Forensic CCTV Video Analysis

By design, at every layer. Reports are never saved on the analysis PC — only evidence photos are, and those are encrypted on disk. Reports publish exclusively to the web panel and open only via secret token links, with the view link delivered to the operator on WhatsApp. Every PDF carries a SHA-256 verification code, a SHA-256 hash of each source video, the operator's name and designation stamp and the station header — so any later tampering with the report or the footage is provable, not just suspected.

Analysis runs fully offline — YOLOv8 detection, tracking, filtering, face recognition against the local suspects folder, OCR and evidence capture all happen on the local machine, which matters for sensitive material. Internet is needed only to publish the case report to the web panel. If connectivity is unavailable when analysis finishes, reports queue locally and upload automatically the moment the connection returns, with the WhatsApp view link sent at that point. Field work in poorly connected areas is a normal, supported scenario.

It is built for real Indian CCTV, not laboratory conditions. Common DVR and NVR export formats are supported for batch analysis, and live RTSP/HTTP streams can be scanned directly. Enhancement and night-vision processing improve dark or grainy frames before evidence capture, and overlay-timestamp OCR recovers the camera's burned-in clock even when DVR metadata is missing or wrong. Detection quality naturally rises with resolution, but the pipeline is tuned to extract usable evidence from typical low-cost camera footage.

Face recognition compares faces detected in footage against a known-suspects folder stored locally on the analysis machine — images the investigating unit itself maintains. Nothing is matched against any cloud database, and the reference folder never leaves the PC, keeping the unit in complete control of this sensitive data. Matches are presented as investigative leads for human confirmation, not automated verdicts. For bystanders, automatic face blurring on saved evidence protects the privacy of people unconnected to the case.

Through the web panel, admins create each operator with their office, designation and WhatsApp number, and set an account validity in days — access expires automatically when a posting ends. Operators can also self-register with WhatsApp OTP, pending admin approval. Every action lands in a full audit log, and login history records PC name, OS, PC username and IP address. Station-wise and monthly statistics, report search, CSV export and bulk ZIP download give supervisors complete oversight, with a Gujarati help guide for local teams.
