v1.24.0

Full data-quality audit of the Dahua brand (master audit #28) — the largest single-brand audit yet: all 155 stored entries verified against official dahuasecurity.com product pages and datasheets. Dahua is a legitimate ONVIF/RTSP enterprise brand, so unlike the consumer brands the problem was fabricated/typo'd model numbers and spec drift, not fake RTSP. Net: 155 → 134 cameras (20 removed, 23 re-keyed/renamed to their real SKUs, ~50 corrected). (Stacks on the v1.23.0 5-brand audit.)

Removed — 20

• 10 ghosts (model strings that return no official product): IPC-HDW2831T-AS-PV / IPC-HDW2849T1-AS-PV / IPC-HFW2849T1-AS-PV (no 2-series 8MP TiOC "AS-PV" eyeball/bullet — that's the 3-series), IPC-HDW5842T-ZE-LED / IPC-HDW5849T1-ZE-LED (no varifocal full-color "-LED"), IPC-HDW7842H-Z4-X (HDW eyeball doesn't exist — it's the HFW bullet), IPC-HFW3849E-AS-LED(-S2) / IPC-HFW3849E-ZAS-LED-S2 (no 8MP "E-AS-LED"), IPC-PT8849-A180 (Dahua A180 panoramics are PFW/PDBW, not "PT").
• 10 duplicates: the fabricated IPC-HDW3849H-AS-PV EU/MENA/UK market-split clones, the IPC-HFW2849S-S-IL MENA/VN clones, IPC-PFW5849-A180 (a fabricated 4-sensor build of the real 2-sensor -E2-ASTE), plus four wrong-SKU strings that collapse onto entries we already have (IPC-HDBW2849H-S-IL-S2→-E-S-IL, IPC-HDBW3849H-ZAS→R1-ZAS-PV, IPC-HFW5842H-Z4E→-Z4HE, SD49225XB-HNR→XA).

Re-keyed / renamed — 23 (real cameras under a fabricated SKU string)

The dataset was riddled with invented model-number infixes, each corrected to the real Dahua SKU with accurate datasheet specs:

• -H-S→-T-S/-TM-S eyeball group (2241/2441/2449/2849, incl. the India-market variant) — Dahua eyeballs are -T-S, not -H-S.
• -PROX→-PRO, S1→T1, -ZE-LED/E-ZAS→ real, PTZ XB→GB (SD6C3432GB-HNR-A-PV1), and the HDCVI re-keys HAC-HFW2802E-LED→**HAC-HFW2802E-A** (it's IR Starlight, not full-color) and the fake 8MP HAC-HFW2849E-A-NI-LED→ real 2MP HAC-HFW2249E-A-LED.

Fixed — ~50 cameras

HDW/HAC-HDW eyeballs mistyped dome→turret; inflated/wrong IR ranges (e.g. SD6AL245XA is 2MP/550m-laser not 4MP/300m-IR; several 3-series bullets 80m→50m); wrong sensor sizes (many 1/2.7"→1/1.8" on WizMind/full-color); a mistyped dual-lens eyeball (HDW5449H-ASE-D2 dome→dual-lens); full-color LED warm-light range 30→15m; and ~70 placeholder/reseller sources replaced with official dahuasecurity.com product pages / datasheet PDFs. ["global"] markets + last_verified: 2026-07-04 applied to all retained entries (regional SKUs keep their market tags).
