Path — Device / System

Device — name, date/time display, reboot schedule

Round-trip tested clean (Ret:100) on 2026-07-25. Only the fields below are exposed as a form. ExUserMap (account password hashes), PwdSafety (security Q&A), GSensorConfig, ManageRemote, ManualCloseEth, DSTState / DST rule specifics, ResumePtzState, TimingSleep, and OneKeyMaskVideo aren't — either genuinely unclear from what we have so far, or risky enough (accounts) to deserve their own dedicated page later rather than a generic field. They're preserved exactly as fetched either way — see the raw JSON below if you need to hand-edit one of them.

Whole-section write — saving sends everything above back, not just one field. Round-trip tested clean (Ret:100 on GET and SET) — see dvrip_roundtrip_test.php's notes on why that's not a full guarantee a write survives a power cycle, just a decent signal.
