FAQ

Q: The top-right badge stays red on LOADING and never turns READY.
Give the Tensor Engine 1–2 minutes to start. If it's still stuck, restart the app or send sentinel-main.log to support.

Q: Camera config upload fails.
Make sure it's valid JSON (commas, quotes, brackets), it's a string array or has a cameras field, no more than 8 URLs, and each URL is a real RTSP URL.

Q: There's no Tensor Engine toggle on my Mac.
Expected — the on-device Tensor Engine (requires a compatible GPU) is Windows / Linux only. Use Tensor Cloud or a remote GPU box.

Q: I'm on a new machine — does my key still work?
Licenses are bound to one machine. If it says "Device not authorised", contact support to re-bind.

Q: Where are the detailed error logs?
The app writes to sentinel-main.log in your OS application-logs folder. Attach it when reporting issues.
