The learner mounts a fixed bullet camera at a marked point on the lounge wall, then aims it by looking through the camera's own lens until the marked floor zone is covered.

A pulsing wall marker with a live distance tag guides you across the office — markers always draw on top of geometry so you can never lose them. Click the floor to walk, click the ladder hotspot to climb.
The bracket starts tilted. Click to snap it level (the guide label flips to LEVEL OK), then hold the button while the two screws visibly sink into the wall as the radial ring fills.
Click the mounted camera and the whole screen becomes its live view. Hold and drag — the camera turns with your hand — until the COVERAGE readout beats the target. No sliders, no abstraction: you are the camera.
When coverage beats the target the green button unlocks. The camera LED goes green, the completion toast shows your score, and +120 XP lands.

Installation process → camera mounting; lens coverage and field of view. The coverage target accounts for real furniture occlusion — a sofa in the zone blocks sightlines exactly like on site.
