The first-person camera records the search as well as the repair. You see the plumber look under the sink, run the faucet, press on a joint, decide, and move on. You see the dripping shutoff valve that turned out to be the real cause. Then the repair itself: pulling a cartridge with pliers, replacing a P-trap, soldering a short copper section, or working a drain auger by feel until it breaks through.
Fixed cameras in the room capture body position and the broader scene. Together with the head camera, a researcher can follow the sequence from the operator and from the room at the same timestamp.
We segment each call into episodes and steps with labels like "locate leak", "replace cartridge", "clear drain", and "verify repair", tagged for success or failure. Optional hand, tool, and object tracking are available. Each batch is delivered to your bucket in your schema, with nothing to reformat. All plumbers are consented and paid, and we collect in real homes and businesses across five countries.
