Turn a wrong CCTV clock into court-ready evidence.
CrimeTime calculates the exact offset between a CCTV system’s clock and real-world time, anchors it to a timestamped photo, and exports a tamper-evident certificate built to stand up in court.

The problem
A CCTV clock is almost never the right time.
DVRs drift. Daylight saving gets missed. Nobody reset the clock when the system was installed. Write “the offender entered at 11:42pm” off a screen that is seventeen minutes fast and you have handed the defence a gap to drive through. CrimeTime closes it, and documents exactly how.
Clocks drift
Cheap DVR clocks lose or gain minutes over months. Nobody notices until the footage matters.
Daylight saving slips
An hour out at the wrong time of year quietly breaks a timeline and any naive conversion.
No defensible record
A note that says it was about twenty minutes out is not evidence. It is an opening for doubt.
How it works
Three steps, from screen to certificate.
No spreadsheets, no manual timezone maths, no expert required.
Photograph the clock
Open the in-app camera and capture the CCTV display showing its current time. CrimeTime stamps the exact real-world moment of the shutter.
Enter the times
Read the CCTV time from your own photo and type it in. Set the moment you need to convert. CrimeTime computes the offset, daylight-saving safe.
Export the certificate
Generate a court-ready PDF with your details, the embedded photos, the full calculation, your signature, and a verifiable SHA-256 hash.
Features
Everything an offset needs to survive cross-examination.
Photo-anchored baseline
Photograph the CCTV screen in-app. At the instant of the shutter, CrimeTime records the device's real time. The photo is the evidence anchor, captured live, never picked from a camera roll.
Tamper-evident hash
Every certificate carries a SHA-256 hash of its canonical data, including the photo. Change one character and verification fails. The maths is deterministic and repeatable.
Public QR verification
Each certificate links to a public verify page and QR code. Anyone, including the court and the defence, can confirm it is unaltered without an account.
Verified Official badge
Sign up with a police or government email and your certificates carry a Verified Official badge, shown on the PDF for added credibility.
Works offline
Install it on your phone like an app. Capture and calculate in the field with no connection, then sync and export when you are back online.
Two-factor secured
Mandatory two-factor authentication before you save your first record. Every officer's data is strictly isolated to their own account.
Built for the witness box
A document that explains itself to the court.
The certificate spells out, in plain English, what the hash proves and how the offset was reached, so you can read it straight to a magistrate. No jargon, no expert witness needed.
- Officer details and Verified Official badge
- The baseline photo of the CCTV screen, embedded
- Full calculation: real-now, CCTV-now, offset, target times
- SHA-256 hash with a public QR verification link
- Your signature and a plain-English court explainer
Change one character and verification fails.
The hash is computed from a canonical record of the exact data, including the photo. Anyone can recompute it on the public verify page and confirm the certificate has not been touched since it was issued. The maths does the vouching, not your word.

FAQ
Questions, answered.
Do I have to be a police officer to use CrimeTime?
No. Sign-up is open to investigators and security professionals as well. Accounts created with a police or government email automatically receive a Verified Official badge that appears on certificates.
How is the time actually anchored?
When you take the in-app photo of the CCTV screen, CrimeTime records your device's clock at the exact instant of the shutter. That timestamp, paired with the CCTV time you read from the same photo, fixes the offset. The photo is embedded in the certificate as the anchor.
What if my device clock is wrong?
You can apply a manual override for the real-world time if you know your device is off, and the override is recorded on the certificate so nothing is hidden.
What does the SHA-256 hash prove?
It is a fingerprint of the certificate's exact data. Anyone can recompute it from the public verify page. If even one value or the photo changed, the hash would not match, so the court can confirm the document has not been altered since it was issued. The certificate explains this in plain English.
Where is my data stored?
In a secured database hosted in Sydney, Australia. CrimeTime is built to comply with the Privacy Act 1988 and the Australian Privacy Principles. Certificates remain verifiable even if an account is later deleted.
