Whoever walks down the alley is the one holding the phone
A rowhouse condenser is reached through an alley a truck cannot enter, so the camera gets decided at the shop rather than at the gate.
The lot behind a Capitol Hill rowhouse is narrow, the gate is narrow, and the alley is the only way to it. Two people carry the lineset, the recovery machine and the gauges down that alley, which means the phone stays in a pocket unless somebody was told to keep a hand free.
Decide it before the truck rolls. One technician works, the other films, and the one filming shoots one handed from about arm's length, because there is nowhere to stand back to.
Get the constraint while it is still visible. The old unit wedged against a fence, the gate the new one has to come through, the clearance somebody has to live with afterward. Once the pad is set and the panel is back on, none of that reads on video.
Duct work inside is a flashlight and a forearm. Vertical framing and a headlamp beat any tripod you own, and the technician should say out loud what he is looking at while the light is already on it, because there is no second take once the wall closes.
You will not film every job on a rowhouse block, and you do not need to. Weight the queue toward the hard ones anyway. An alley job costs more to shoot than a Fairfax County driveway and it answers a question the driveway never raises.
