There is only one file type that uses the .JVSG extension:
Video Surveillance Project
Project file created by JVSG's CCTV (Closed-Circuit Television) system design programs; stores camera locations, camera view angles, bandwidth and hard disk calculations, and other CCTV design information; can be rendered into 3D views for advanced analysis and documentation.
JVSG project files are used for designing security camera networks for banks, retail stores, car sales lots, and other businesses that require security cameras.
