4+4 MP dual-channel security camera
Dahua SDT4E425-4F-GB-A-PV1-S2 combines a 4 MP panoramic camera with a 4 MP PTZ detail camera in one housing. The panoramic channel provides wide overview coverage, whilst the PTZ channel with 25× optical zoom allows detailed observation and tracking of objects of interest.
Panoramic camera with 2.8 mm lens
The panoramic channel features a 2.8 mm F1.0 lens with approximately 101° horizontal field of view. It is designed for continuous monitoring of large areas.
PTZ camera with 25× optical zoom
The detail channel uses a 5–125 mm motorised zoom lens with 25× optical magnification. The horizontal field of view ranges from 51.9° to 3°, allowing switching from wide view to highly detailed observation of distant objects.
Smart Dual Light
The panoramic camera provides up to 30 m IR and 30 m warm white light illumination. The PTZ detail camera provides up to 100 m IR and up to 50 m warm white light illumination.
Auto Tracking 3.0
The camera can automatically track objects of interest using a combination of panoramic and PTZ cameras. The panoramic channel detects the object, whilst the detail camera can automatically zoom in and follow its movement.
Xinghan AI and intelligent analytics
The camera uses Dahua Xinghan large-scale AI models, as well as SMD 4.0 and intelligent perimeter protection functions. Support is provided for human and vehicle classification, intrusion, line crossing, loitering, human gathering, rapid movement and other event detection.
Active Deterrence
The integrated active deterrence system uses red and blue light warning and audio alerts. 11 types of audio alarm are available, as well as the option to use custom audio alerts.
WDR 120 dB
True WDR up to 120 dB helps preserve detail in complex lighting conditions. The camera additionally supports 2D/3D noise reduction, BLC, HLC, ROI, EIS and Defog functions.
Two-way audio
The camera has two built-in microphones and a speaker, providing real-time two-way audio communication.
PoE+ power supply
The camera supports 12 V DC and IEEE 802.3at PoE+ power supply. Maximum consumption can reach 25 W when using illumination, heated window, Active Deterrence and PTZ functions.
IP66 and surge protection
The camera is designed for outdoor use and equipped with IP66 protection. TVS 6000 V protection provides additional durability against lightning, surge and voltage transient effects.
