Question 1

How is DNA different from regular video conversion tools?

Accepted Answer

Regular tools focus on fast conversion. DNA focuses on legal review, chain of custody, and reproducibility. We preserve metadata, validate cryptographic integrity, and log every action for court review.

Question 2

Is metadata preserved when material is converted?

Accepted Answer

Yes. Timestamps, camera names, frame rates, and other critical metadata are preserved and documented in the MP4 container and the audit log. Nothing is lost.

Question 3

Can you support new or proprietary formats?

Accepted Answer

Yes. DNA is extensible. We can develop support for new formats as needed. Contact us to discuss specific formats.

Question 4

Does DNA use artificial intelligence or generative technology?

Accepted Answer

No. DNA uses strictly deterministic algorithms. No AI, no "guessing" pixels, no machine learning. This guarantees legal validity and reproducibility.

Question 5

How are corrupted or incomplete video files handled?

Accepted Answer

DNA uses advanced stream recovery (carving) to extract H.264 streams from corrupted containers. We reconnect them with the correct start time from metadata to recreate usable files.

Question 6

Is DNA compatible with other forensic tools?

Accepted Answer

Yes. DNA exports to standard formats (MP4 H.264/HEVC) and is fully compatible with FFmpeg, MediaInfo, mpv, and other industry-standard tools.

Question 7

Does forensix.se save or store my data?

Accepted Answer

No. The DVR calculator and TimeChex run entirely in your browser on your device. Times, INFO fields, camera images, and calculations are processed locally – nothing is sent to our servers and we have no access to what you enter. After confirmation, a watermark reading "TimeChex captured with Verified by Forensix.se" is burned into the evidence image, and a SHA-256 hash is computed for the exported JPEG and carried into the forensic report text. The evidence image is only saved when you choose to save it to your phone's photo album. Session measurements are stored temporarily in the browser's local storage on the same device and can be cleared with one tap.

Question 8

How does Forensix TimeChex handle privacy?

Accepted Answer

TimeChex only starts the camera when you tap Start camera. The camera view is shown as a split screen where the camera for the DVR time and the reference panel default to a 50/50 split (which you can adjust by dragging the divider up or down). OCR and time calculations run locally on your device via local AI models (PaddleOCR, ONNX and Tesseract.js LSTM) with multi-frame consensus for more stable results under motion blur, without the image ever leaving your browser. No external servers or cloud APIs are called for image analysis. Reference time may sync via NTP (an external time server) but no investigation data or images are transmitted. When you confirm the image, the watermark "TimeChex captured with Verified by Forensix.se" is added before export, and the SHA-256 hash of the finished evidence image is carried into the forensic report text. After confirmation, a single JPEG is offered via the share sheet – choose Save Image to add it to Photos. Forensix.se does not store, analyse, or have access to your images, locations, or time entries.

Question 9

How can I get help with an unknown CCTV format?

Accepted Answer

Contact us via the form and provide the file extension and technical context. We will help with format review and recommend the best next step.

Question 10

How does Converter Online work and what happens if conversion fails?

Accepted Answer

Converter Online attempts local browser-side conversion of imported video files. No files are uploaded to any server. If conversion is not possible, you get a clear technical explanation.

Question 11

Do you track my visits on forensix.se?

Accepted Answer

We count aggregated page views via a dedicated Cloudflare Worker (no raw IP stored) and aggregated traffic in Cloudflare Analytics. This is only used to understand traffic patterns, countries, and most visited tools at an aggregated level. Every page view counts — not just the first visit. No investigation data or evidence is collected – all tools run locally on your device.

Question 12

Do the DVR Calculator and Forensix TimeChex work offline at a field?

Accepted Answer

Yes. Both the DVR Calculator and Forensix TimeChex are Progressive Web Apps (PWA) that run completely locally in the browser. All image analysis, OCR readings, and time calculations are processed offline on your device – no internet connection or cellular coverage is required at the field. You can also install the tools overview (Forensix) as an app from the home screen for quick access to the tools.

Question 13

How does Forensix Cam work and what does Forensix store?

Accepted Answer

Forensix Cam is a web-based documentation camera for photos and videos. The on-image layer shows optional INFO 1 and INFO 2 (e.g. case number and address), date, time, GPS, and compass – without labels for your own text. Time source (NTP or device) is documented in the report (PDF/JSON), not on the image. All processing runs locally in your browser – no image, video, GPS, or metadata is sent to Forensix. After capture, a report with SHA-256 and SHA-512 is generated automatically. Compass requires a phone with a magnetometer and permission; on most desktops it shows as unavailable. GPS is optional. You save files yourself via the share sheet; we store nothing. Verify later with the hash verifier.

Question 14

Can I install forensix.se as an app on my phone?

Accepted Answer

Yes. On Android, tap Add when the browser prompts you. On iPhone, open the page in Safari and choose Share → Add to Home Screen – we show a visual guide when you tap Add. The tools overview, TimeChex, and Forensix Cam can each be installed as separate apps. Install is always available under the More menu.
