PTZ Camera X-Spans SDT4E425-4F-GB-A-PV1-S2

The Dahua SDT4E425-4F-GB-A-PV1-S2 is a dual-channel X-Spans network PTZ camera combining a fixed 4MP 2.8 mm overview lens with a 4MP 25x optical zoom detail channel (5-125 mm) for simultaneous wide-area surveillance and close-up detail capture. The detail channel's IR reaches up to 100m, complemented by Dahua's Smart Dual Light+ warm-light illumination for full-color night vision. Powered by Xinghan's large-scale AI models, the camera delivers Auto Tracking 3.0, smart/relay tracking, face detection, SMD 4.0, and a complete IVS suite for perimeter surveillance (tripwire, intrusion, loitering, abandoned object, and more), combined with active deterrence via red-blue light warning and configurable audio alarms. Built-in dual microphones and a speaker enable two-way communication, and the IP66-rated, wide-temperature (-40 to +65 degrees C) housing with PoE+ support suits demanding outdoor installations for perimeter protection and critical infrastructure.
