Sales negotiation
A salesperson runs a closing over video: they look into the camera to create "eye-to-eye" contact, share their screen to walk through the offer, and watch for the client's micro-reactions when the price is announced.
Look at the camera, not the screen, at key moments, and steer the screen share to anchor each point.
Restores an almost human relationship and lets you read reactions to the offer in real time.
A poor connection or careless framing undermines credibility at the worst possible moment.
