Comparison
4K Chat vs Zoom
Zoom is built for reliable, low-bandwidth meetings across enterprise networks. 4K Chat is built for the opposite — small, high-fidelity, private calls between people on modern devices and good pipes. Here's how the two stack up feature-by-feature.
| Feature | 4K Chat | Zoom |
|---|---|---|
| Max video resolution | Up to 8K — resolution follows your hardware | 1080p (Pro+) |
| Where media is decoded | Directly between peers | Zoom's SFU cluster |
| Room style | A small full mesh — everyone connects directly | Routed through Zoom's servers |
| Capture cards / extra cameras | Join as their own approved participants — IP cameras coming | Screen share only |
| Per-camera adaptive bitrate | Yes — cameras yield uplink to people | Not applicable |
| When the network breaks | Self-healing: unbounded ICE restarts, media watchdog | Reconnect prompt / rejoin |
| End-to-end encryption | On by default, per-frame optional | Opt-in, disables cloud features |
| Cloud recording | None — recordings stay on your device | Stored on Zoom cloud |
| Signup required to join | No | Sometimes |
| Smart TV support | Cast or mirror from phone/PC. No Smart TV store app today. | Limited casting only |
| AI agent access | OAuth MCP for agents — in development / not a public install path yet | No |
| Free-tier time limit | None — unlimited | 40 minutes |
| Free-tier participants | Up to 4 | 100 (but 720p mixed) |
Which one wins, by scenario
| Scenario | Better fit | Why |
|---|---|---|
| Remote production monitoring | 4K Chat | Real 4K/8K per camera, with capture cards as their own participants instead of a capped screen share. |
| Live site & security monitoring | 4K Chat | Cameras join as host-approved participants on a session designed to run 24/7 — IP camera bridging (WHEP, RTSP, MJPEG) is coming. |
| Sensitive incident review | 4K Chat | Media is peer-to-peer and end-to-end encrypted, with no cloud recording copy to govern. |
| Remote interviews & podcasts | 4K Chat | Each side records locally at capture quality rather than accepting a cloud mixdown. |
| 500-person all-hands webinar | Zoom | Broadcast-scale one-to-many is exactly what a big SFU is for. |
| Dial-in phone bridges and PSTN | Zoom | 4K Chat is browser and app only — there is no telephony gateway. |
| Procurement that requires a signed BAA today | Zoom | We publish our architecture, not compliance certifications. |
