Print this before the service visit. Test on the network and devices the technician and expert will actually use; a desk rehearsal on different Wi-Fi does not prove the site path.
Camera and light
- □ Charged phone or tablet with a clean lens, charger or power bank, and a stable grip or mount.
- □ Small soft work light or flashlight positioned to reveal the fault without glare.
- □ Optional USB camera, borescope, or capture-card feed exposed by the operating system and approved by the host.
- □ IP camera bridging is coming, not live; do not depend on WHEP, HLS, MJPEG, or RTSP for today's job.
Room and people
- □ Name who starts the room and who watches the waiting room before hands-on work begins.
- □ Send one browser link; native apps are in development and the browser is the path today.
- □ Verify contractor names and admit only expected people and camera sources.
- □ Count everyone and every extra camera: Free 4 / Pro 12 / Cinema 32.
Network and display
- □ Test the actual site network. Free has no TURN, so hard NAT or a locked plant network may fail.
- □ Pack or approve a spare uplink such as a hotspot; use wired networking when practical.
- □ Confirm the expert sees the decisive detail. Resolution follows hardware and network at both ends; 4K/8K is not guaranteed.
- □ If the expert receives on a TV, cast or mirror a phone or PC browser. There is no Smart TV store app.
Plan and safety
- □ If evidence must be recorded, use Pro or Cinema local recording and verify the WebM on the recording device; Free does not include recording.
- □ Keep the phone and technician clear of moving machinery and follow the site's approved lockout and safety process.
- □ Do not use 4K Chat for emergency, life-safety, or public-safety communications.
