Tuya video doorbell cam (Oadby)

This was gifted by the police about 18 months/2 years ago, worked perfectly well until a few days ago when it went "offline " and all attempts to get it working again have failed. Have mislaid the instruction leaflet. Maybe someone a bit more tech savvy than myself could make use of it? Please don't ask for this if you have no intention of collecting.
