Product SKU: DS-2DF8C442IXG1-ELW
Product Overview
The Hikvision DS-2DF8C442IXG1-ELW 4MP DarkFighter 2.0 PTZ Camera combines long-range 42× optical zoom, intelligent target tracking and powerful infrared illumination for large-scale perimeter and site surveillance. Its 1/1.8-inch progressive scan CMOS sensor captures up to 2688 × 1520 resolution, while DarkFighter 2.0 technology and 140dB WDR help preserve useful detail in low-light and high-contrast conditions. The 6–252mm motorised zoom lens allows operators to inspect distant activity, while infrared illumination reaches up to 400m. Human and vehicle classification, face capture, road-traffic analytics, rapid PTZ movement, built-in wiper, audio and alarm interfaces, MicroSD storage, IP67 protection and NEMA 4X anti-corrosion performance support demanding commercial, industrial and critical-infrastructure applications.
Key Capabilities
42× Long-Range Optical Zoom
The 6–252mm motorised lens moves from wide-area overview coverage to tightly framed inspection of distant people, vehicles and assets.
400m Infrared Illumination
High-performance infrared lighting supports long-distance monochrome surveillance in darkness at ranges up to 400m.
DarkFighter 2.0 Imaging
Advanced low-light processing delivers clearer colour and monochrome footage in challenging nighttime and low-contrast scenes.
Intelligent Target Classification
Deep-learning analytics classify people and vehicles for supported perimeter events to reduce alarms from irrelevant movement.
Smart Tracking and Rapid PTZ
Automated tracking, presets, patrols and high-speed pan-and-tilt movement help operators follow targets across large sites.

Buyer Decision Tips
Buyer Tip: Confirm that the target distances, mounting height and expected field of view suit the 6–252mm lens. Long-range identification requires stable mounting and a clear line of sight.
Buyer Tip: Use a compatible Hikvision recorder or management platform that supports PTZ control, intelligent events, tracking, face capture and sufficient incoming bandwidth.
Installation Note: This large PTZ requires a rigid structural mount, suitable power supply, surge protection, weatherproof cable management and professional commissioning.

FAQs
- What resolution does the DS-2DF8C442IXG1-ELW record?
The camera records at up to 4MP resolution, measuring 2688 × 1520 pixels. It also supports high-frame-rate recording at selected lower resolutions for fast-moving scenes. - How much optical zoom does the camera provide?
The motorised 6–252mm lens provides 42× optical zoom. This allows the camera to move from a wide overview to a narrow telephoto view of distant people, vehicles or site details. - How far does the infrared illumination reach?
The integrated infrared system is rated for distances up to 400m. Actual performance depends on atmospheric conditions, target size, zoom position, camera alignment and surrounding reflectivity. - What is DarkFighter 2.0?
DarkFighter 2.0 combines a high-performance sensor, large-aperture optics and advanced image processing to improve colour and monochrome image quality in very low-light environments. - Can the PTZ automatically track people and vehicles?
Yes. The camera supports intelligent target classification and automatic tracking for compatible events. Performance depends on correct scene design, calibration, target size, lighting and analytics configuration. - Does the ELW model include a wiper?
Yes. The ELW version includes a built-in wiper to help clear water and contamination from the viewing window. Maintenance and periodic inspection are still required. - Is the camera suitable for outdoor and coastal installations?
The camera carries IP67 and IK10 protection, while the -Y version provides NEMA 4X moderate anti-corrosion performance. Highly aggressive marine or chemical environments may require a specialised top-level anti-corrosion model. - What should I check before purchasing this PTZ camera?
Confirm the target distances, mounting structure, power requirements, NVR compatibility, intelligent feature support, network bandwidth, storage and environmental exposure. Security Wholesalers can supply this model for professionally designed long-range Hikvision surveillance systems.
