Product SKU: DS-2DF8442IXG1-ELWY
Product Overview
The DS-2DF8442IXG1-ELWY is a flagship Ultra Series PTZ speed dome from Hikvision’s DF8 range, tailored for expansive outdoor surveillance where performance cannot be compromised. Featuring a 1/1.8″ progressive-scan CMOS sensor delivering up to 2688 × 1520 (4 MP) resolution, it combines a powerful 42× optical zoom (6.0–250 mm) with 16× digital zoom to capture distant detail with clarity. Utilising DarkFighter 2.0 technology and boasting a minimum illumination as low as ~0.0003 Lux, the camera performs in extremely low-light conditions. With a 150 dB adaptive WDR, built-in gyroscopic stabilisation, full 360° pan and –20° to +90° tilt, plus rugged IP67 / IK10 construction with optional wiper (W) and enhanced “Y” specification, it is engineered for airports, ports, highways, industrial perimeters and other mission-critical outdoor sites.
Why Choose the DS-2DF8442IXG1-ELWY
If your installation demands top-tier PTZ capability, long-range zoom, ultra-clear imagery and day-night readiness—this model ticks every box. The 42× optical zoom gives you broad situational coverage and then the ability to zoom into fine detail at range. DarkFighter 2.0 ensures usable colour imagery in very low light, while the 150 dB WDR handles high contrast scenes such as building entrances, reflective surfaces or dusk/dawn environments. The rugged build—including IP67/IK10 rating and optional corrosion-resistant features—and extended zoom range mean that the DS-2DF8442IXG1-ELWY is ideal for large-scale outdoor surveillance across challenging environments.

Choosing Between Wide and Tele Zoom Settings
The DS-2DF8442IXG1-ELWY features a motorised zoom lens from 6.0 mm (wide) to 250 mm (tele). At the wide end you’ll have approximately 56.6° horizontal field of view—perfect for broad situational awareness around building perimeters or open yards. At the tele end (250 mm) the horizontal field of view narrows significantly (down to around 1.7°), giving you the capability to inspect distant subjects, vehicle lanes or access points. Use wide for coverage; switch to telephoto for detailed inspection or tracking.
