The footage covers the whole visit, not just the spray. Removing filters and washing them in a sink, applying coil cleaner and waiting for it to foam, scrubbing the blower wheel with a long brush, flushing the condensate line, checking refrigerant pressure at the outdoor unit, and reassembling everything so the cover sits flush. The technician wears a head-mounted camera, so the view shows exactly where their hands go inside the chassis, including the moments where they stop, look, and decide.
Fixed cameras in the room and at the outdoor condenser capture the same visit from the outside, synchronized with the head camera. That gives a researcher both the operator view and a third-person view of ladder work, body position, and tool handling at the same timestamp.
Each visit is delivered as an episode broken into steps with plain-language labels like "remove front cover", "foam evaporator coil", or "test drain flow". Steps carry success or failure tags, and we can add hand, object, and tool tracking on request. Data arrives in your schema, written to your storage, from consented and paid technicians working real service routes in five countries.
