Product SKU: DS-2DF8C842IXG1-ELWY
Product Overview
The DS-2DF8C842IXG1-ELWY is a premium 8 MP Ultra-Series PTZ speed dome designed for large-scale, high-security outdoor surveillance. With a 1/1.2″ progressive-scan CMOS sensor delivering ultra-HD 3840 × 2160 resolution, a powerful 42× optical zoom (7.5–315 mm) combined with 16× digital zoom, and advanced DarkFighter 2.0 low-light technology, it captures exceptional detail even in challenging lighting. Built for harsh conditions, the unit offers up to 500 m IR night vision, 140 dB AWDR, and a rugged IP67/IK10 rated enclosure (excluding dome). Its wide-angle to extreme telephoto capabilities make it ideal for transportation hubs, critical infrastructure, perimeter security and expansive outdoor sites.
Why Choose the DS-2DF8C842IXG1-ELWY
If your installation demands ultra-high resolution, extreme zoom capability and robust durability in outdoor or mission-critical environments, the DS-2DF8C842IXG1-ELWY delivers. The combination of 8 MP image quality and 42× zoom enables identification of distant targets without sacrificing clarity, while DarkFighter 2.0 ensures colour performance in very low light. The long-range IR and high dynamic range (140 dB) offer reliable results in dawn, dusk, shadows and back-lit scenes. Its PTZ mechanics, advanced analytics and rugged construction equip it for perimeters, seaports, large campuses or transport hubs where performance and reliability count.
Key Capabilities
8 MP Ultra-HD Imaging
The large-format 1/1.2″ sensor delivers 3840 × 2160 resolution, enabling highly detailed capture of people, vehicles and scene elements even when zoomed far out—ideal for forensic-level clarity across wide-area surveillance.
42× Optical Zoom (7.5–315 mm)
This motorised lens dramatically extends your view—from approximately 60.4° horizontally at the wide end down to around 1.7° at full telephoto—making it suited to long-range monitoring and secure sites where distant detail is critical.
Exceptional Low-Light & Night-Vision Performance
DarkFighter 2.0 technology allows colour imagery at very low ambient light (~0.0005 Lux) and, combined with IR illumination reaching up to 500 m, provides dependable surveillance through night, dawn and poor-light conditions.
Full PTZ Motion & Smart Tracking
With 360° continuous pan and −20° to +90° tilt (auto-flip), plus presets, patrol scans and smart correction, the camera dynamically covers large zones, tracks moving objects and ensures continuous monitoring of complex outdoor environments.
Durable Outdoor Construction
Housed in weather- and vandal-resistant casing rated to IP67 and IK10 (excluding dome), with operation from −40 °C to +70 °C, this camera is built to withstand harsh environments such as coastal corridors, industrial perimeters or transport infrastructure sites.
Key Features

-
7.5–315 mm motorised lens: Ranges from wide-angle to narrow telephoto, enabling both situational awareness and precise detail inspection from long distance.
-
DarkFighter 2.0 + ultra low-light capture: Maintains usable colour imagery down to ~0.0005 Lux ambient and supports IR to 500 m for clear monitoring when light is minimal.
-
140 dB AWDR + Smart Pan-Tilt Correction: Ensures effective imaging in high-contrast lighting (bright and dark together) and supports stable tracking and panning across large site areas.
-
IP67 & IK10 housing + wide temperature range: Weatherproof, vandal-resistant and capable of operation in extreme climates—suitable for exposed outdoor installations or harsh industrial environments.

Ideal Use Cases
- City Surveillance – Monitor wide-area public zones, urban streets and transport hubs with ultra-zoom and high resolution.
- Critical Infrastructure – Secure power plants, airports, seaports and government facilities where long-range clarity and analytics are essential.
- Traffic & Highway Monitoring – Oversee roadways, entry/exits and perimeters with high definition and zoomed-in identification capability.
- Large Open Areas – Suitable for stadiums, industrial sites or campuses where one camera must cover broad spaces and still maintain detail zoom capability.
- Harsh Outdoor Environments – With weather and impact-resistance plus extended temperature range, it excels in exposed or industrial locations such as coastal zones or factory perimeters.
Choosing Between Wide and Tele Zoom Settings
The DS-2DF8C842IXG1-ELWY supports a motorised zoom range from 7.5 mm (wide) to 315 mm (tele). At the wide-end you achieve approx. 60.4° horizontal field of view — ideal for situational and broad coverage. At the tele-end (~315 mm) the field narrows to ~1.7°, perfect for distant inspection of objects, vehicles or people.

Tip:
Use the wide setting for broad scene monitoring; switch to the telephoto setting when detailed inspection or target zooming is required.
FAQs
- What does “42× Optical Zoom” mean?
This means the lens can magnify the subject up to forty-two times without degrading image quality (unlike digital zoom which enlarges pixels). It enables clear observation of distant objects while maintaining clarity.
- What is DarkFighter technology?
DarkFighter 2.0 is the advanced low-light imaging technology built into this camera, allowing it to maintain colour in very low ambient illumination and shift into IR when needed—ensuring usable footage even in near-dark conditions.
- Is this camera suitable for harsh outdoor or coastal conditions?
Yes — the housing is built to IP67 (dust/water proof) and IK10 (impact resistant, excluding dome), and rated from −40 °C to +70 °C. With built-in IR to 500 m, it’s ideal for exposed sites, industrial yards or large-scale perimeter applications.
