DVR Calculator

Built for investigators handling DVR and surveillance footage. Quickly calculate time offsets, timestamp differences, and store calculations locally.

DVR Calculator is a practical investigative utility designed for detectives, investigators, and security professionals working with surveillance video and DVR systems.

• DVR and CCTV time offset calculations • Corrected timestamp conversion • Save calculations locally on device • Organize and sort entries by address • Quick access to previous calculations • Fast, investigator-focused workflow • Useful for CCTV, DVR, NVR, and exported surveillance footage • Streamlined interface designed for field and investigative use

Built specifically for real-world investigative and surveillance review workflows.
