    The facts, in one place

    SMB field technicians, plant maintenance, and remote OEM specialists who need the expert to see the fault on a real camera feed — not a blurry phone share into Teams.

    A modern browser, a camera, and a solid uplink. For a big screen, cast or mirror from your phone or PC.

    Resolution
