DVR Calc: CCTV Time Calculator

Yigal Cohen

About this app

DVR Calc helps you find the exact time to search on a DVR or NVR when the recorder clock does not match the real time.

Simply enter the time shown on the recording device, the actual current time, and the real time of the event. DVR Calc automatically calculates the time difference and gives you the exact time to search for on the recorder.

DVR Calc can calculate DVR/NVR clock offsets, find the exact recording time for an event, handle recorders that are ahead of or behind real time, and save event information for later reference.

Event numbers, addresses and notes can be stored in the app, and calculated information can be copied quickly when needed. The interface is available in Hebrew and English.

DVR Calc works completely offline. No account or registration is required, and no personal data is collected or transmitted. Calculations and entered information remain on the user's device.

The app is designed for fast and reliable use in the field and is particularly suitable for law enforcement, security forces, investigators, security teams, CCTV technicians and other professionals working with video surveillance and recording systems.

DVR Calc reduces manual time calculations, helps prevent calculation errors and makes locating relevant video footage faster and easier.
