Dahua SDT4E425-4F-GB-A-PV1 X-Spans 4MP Dual‑lens PTZ 25x optical zoom (incl. wall mount)
The Dahua SDT4E425-4F-GB-A-PV1 X‑Spans offers it all. This smart dual‑lens camera combines a wide overview lens with a 25x optical zoom PTZ. This gives you both the big picture and the smallest details in one system. With Full‑Color Starlight for 24/7 colour images, active deterrence with a siren and flashing light, and smart WizSense AI, this is the ideal choice for businesses and demanding home users who want reliability and value. Install, operate and receive notifications directly via the DMSS app.
What this camera does
The Dahua X‑Spans dual‑lens technology delivers both an overview and a close-up at the same time, so no moment is lost. The PTZ automatically follows people or vehicles (auto‑tracking) and zooms in smoothly without jerky images. Thanks to WizSense AI, notifications are filtered more intelligently, so you only receive a notification for relevant events. Active deterrence with a white LED light and an audio alarm up to 110 dB works preventively and can even be extended with your own sound recordings. This camera is weather-resistant, robust and easy to operate via the DMSS app. The result: fewer false alarms, more usable evidence and maximum peace of mind at an affordable price.
