Dahua DH-SDT4E425-4F-GB-A-PV1-0280-S2 — 4+4MP 25x X-Spans Active Deterrence PTZ Camera
The DH-SDT4E425-4F-GB-A-PV1-0280-S2 is an X-Spans camera combining a fixed 2.8mm overview lens with a separate 4MP, 25x zoom PTZ head in one housing, plus built-in siren, red/blue strobe and two-way talk for active deterrence — one mounting point covers a wide fixed view and can zoom in and challenge an intruder.
Who is it for?
Sites wanting a wide fixed overview and PTZ zoom-in detail from one unit, with the ability to actively challenge an intruder using light and sound rather than only recording — building sites, yards, warehouse perimeters.
