This is the first *vendor-sourced* spec data for the model; everything before it was field-derived. ## Key takeaways - **4 MP, max resolution 2560×1440** (ColorVu 3.0 — color night imaging, not IR-only). - **Main stream: H.265+/H.265/H.264+/H.264 only — no MJPEG option.** **Sub-stream: H.265/H.264/ MJPEG** (MJPEG is sub-only). This is a concrete, spec-level asymmetry that plausibly explains *why* the ISAPI on-demand JPEG snapshot is reliable on sub but structurally broken on main: sub can serve a snapshot natively, main has to transcode out of H.264/H.265 on demand. Consistent with — and a likely root cause for — the persistent `deviceBusy` behavior already logged in [[lpr-camera]]. - **Bit rate range 32 Kbps–16 Mbps.** The site's main-stream config (6144–12288 Kbps, confirmed live 2026-08-23) is well inside spec — rules out "misconfigured over the camera's own ceiling" as a cause, confirming what live testing already showed. - **ROI: 1 fixed region for main stream** — another main-only constraint/asymmetry vs. sub. - **API: ONVIF (Profile S, Profile G), ISAPI, SDK.** ISAPI is fully in-spec for this model — the 503 is a real firmware/hardware limitation, not a case of using an unsupported API. - **Protocols include RTSP** (alongside HTTP/ONVIF/etc.) — confirms RTSP is a documented, supported surface on this model, not a workaround outside its design. - Simultaneous live view: up to 6 channels. Available in `-LIU`/`-LIUF`/`-LIUF/SL`/`-LIUF/SRB` variants at 2.8mm/4mm focal lengths; the deployed unit is the base `-LIU`. ## How this changes the picture Confirms rather than overturns [[lpr-camera]]'s existing conclusion (sub-stream-only for ISAPI snapshots on this model) — but gives it a concrete mechanical explanation (main has no MJPEG path) instead of just an empirically-observed limitation. See [[lpr-camera]] § "Main-stream ISAPI snapshot 503 vs. RTSP" for the 2026-08-23 live comparison against a `DS-2CD1043G2-LIU` sibling (main-stream ISAPI snapshot works fine there) and the confirmed RTSP frame-grab workaround.
