The Hikvision DS-2DF8442IXG1-ELWY DF8 Series 4MP 42× DarkFighter IR Network Speed Dome is a high-performance professional PTZ security camera designed for long-range surveillance, critical infrastructure, transport, industrial and large outdoor environments. Featuring a 4MP 1/1.8" Progressive Scan CMOS sensor, 42× optical zoom, 16× digital zoom, DarkFighter 2.0 technology, 150 dB WDR, up to 400m IR illumination, Auto-Tracking 3.0, face capture, face comparison, vehicle analytics and license plate recognition, the DS-2DF8442IXG1-ELWY delivers powerful long-distance monitoring in both daylight and challenging low-light conditions.
The camera's 6–250mm 42× optical zoom lens allows operators to move from a broad 56.6° horizontal view to a narrow 1.7° telephoto view for detailed observation of distant targets. Rapid PTZ performance provides configurable pan speeds up to 210°/s and preset pan speeds up to 280°/s.
For night surveillance, the DS-2DF8442IXG1-ELWY incorporates smart infrared illumination with a specified range of up to 400 metres. DarkFighter 2.0 technology and a large 1/1.8" sensor provide enhanced low-light imaging, while 150 dB WDR helps retain detail in scenes with significant differences between bright and dark areas.
Advanced deep-learning capabilities include simultaneous human body, face and vehicle detection, face capture, face comparison, perimeter protection, license plate recognition, vehicle attributes and intelligent target tracking.
Designed for exposed outdoor installations, the DS-2DF8442IXG1-ELWY is specified with IP67 environmental protection, IK10 impact protection excluding the glass window, NEMA 4X anti-corrosion protection, lightning and surge protection, together with a wide –40°C to +70°C operating range.
