Independent. Neutral. Built for the job.
Evidence aligned. Proven by time.
CrimeTime is an independent tool, designed around the real work of CCTV canvassing, evidence handling, and court-brief preparation. It takes no side. It establishes one true time on the footage, and the calculation can be checked by anyone, for or against.
- Independent tool
- Impartial calculation
- Independently verifiable
- Built around real casework
The core tool
Find the exact moment in seconds, not hours.
Enter the time the recorder is showing, the real time now, and the moment you need. CrimeTime returns the precise time to scrub to on that device, daylight-saving safe. No spreadsheets, no timezone maths, no guesswork.
- Works on any recorder, however far its clock has drifted
- One offset per camera, applied across every moment on the job
- Copy the search time and go, then make it official when it counts
1. Time shown on the CCTV drive right now
2. The actual date and time right now
3. Date and time of the incident you are searching for
Search the drive at
24 Jun 2026, 22:32:04
The drive shows 08:50:14, a later time than the real 08:33:10.
So the drive is 17m 04s ahead of real time.

See it in action
The whole flow in under a minute.
From a wrong CCTV clock to the exact device time and a verifiable record, the way it runs on a real job.
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. Rely on a screen that is seventeen minutes fast and the timeline is wrong for everyone, prosecution and defence alike. CrimeTime fixes the time and documents exactly how, so it can be tested.
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, on either side.
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 clean PDF record with the embedded photos, the full calculation, a signature, and a verifiable SHA-256 hash anyone can recompute.
Features
Everything that makes the time checkable, by anyone.
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 by anyone.
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 context. The maths still stands on its own either way.
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 user's data is strictly isolated to their own account.
Plain English, by design
A record that explains itself.
The certificate spells out, in plain English, what the hash proves and how the offset was reached, so any party can read and understand it without an expert. No jargon, and nothing that only one side can check.
- Issuer details and optional 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
- A signature and a plain-English 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 anyone’s word.

Who it is for
One impartial record, relied on by every side.
CrimeTime does not advocate. It establishes the true time on the footage so each side can rely on the same, checkable record.
Police & detectives
Sworn officers and investigators
Capture and prove the exact offset in the field, then read off the precise device time to search to. One defensible record across every camera and site on the job.
Private investigators
PI, insurance, corporate & loss-prevention
Turn a wrong CCTV clock into the exact search time in seconds, and give your client a clean, verifiable record of how the time was established.
Lawyers & solicitors
Presenting CCTV in court
Put the right time on the footage you rely on, and independently test the other side's. No account is needed to confirm a certificate, so nothing rests on trust.
Courts & the judiciary
Clerks, registry, magistrates & judges
Receive certificates you can confirm in seconds, with a plain-English explainer and a public hash check. No expert witness required to test the time.
Verification, open to anyone
No account. No expert. Just the maths.
Every certificate can be checked by anyone. Open its verify page, or scan the QR code on the PDF, and CrimeTime recomputes the SHA-256 hash from the certificate’s own data. If it matches, the document is unaltered. If a single value or the photo changed, it will not. Either side, or the court, can confirm a certificate without taking anyone’s word for it, and without signing up.

FAQ
Questions, answered.
Is CrimeTime only for police?
No. CrimeTime is a neutral, independently verifiable tool. Investigators, insurers, corporate and loss-prevention teams, lawyers acting for either side, and court staff all use it. Accounts created with a police or government email receive a Verified Official badge on certificates, but the underlying maths can be checked by anyone, regardless of who issued the document.
Is the time impartial, or does it favour one side?
It is impartial by design. The offset is a deterministic calculation anchored to a live photo, and the result is the result whoever runs it. The defence can produce their own certificate to test the prosecution's, and the court can recompute either one. CrimeTime takes no side; it establishes the true time on the footage.
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, with no account. If even one value or the photo changed, the hash would not match, so any party 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, access-controlled database with strict per-account isolation and mandatory two-factor authentication. Certificates remain verifiable even if an account is later deleted.
How much does it cost?
One simple fee. Choose $29.95 a year (cancel anytime) or $149.95 once for lifetime access. Both unlock the full app and official, verifiable certificates. No hidden fees, no ads, no upsells, nothing else to pay. Government, corporate and agency buyers can contact us for wholesale and per-licence pricing.
