PotoP VMS for Android puts the full VMS in your pocket: camera walls, playback, floor plans, the softphone and alarms. It pins your server's certificate on first contact and signs you in with your fingerprint or face.
PotoP Enterprise Suite for Android gives field staff and planners their day on one screen: jobs, faults, dispatch, the live map, timesheets and end-to-end encrypted chat.
Both apps receive notifications straight from your own server — no Google push service in between. Both run on Android 8.0 or newer.
