Product SKU: DS-2DT8C442MXG-LWT
Product Overview
The DS-2DT8C442MXG-LWT from Hikvision is a 4 MP anti-corrosion network speed dome built for large outdoor and industrial applications. Featuring a 1/1.8″ progressive-scan CMOS sensor delivering up to 2560 × 1440 resolution, it incorporates 42× optical zoom (6.0–252 mm) and 16× digital zoom for outstanding long-distance coverage. With DarkFighter low-light technology, hybrid IR/white-light illumination reaching up to 500 m IR and 100 m white light, IP67 water/dust protection, and an anti-corrosion polymer enclosure, this camera is engineered for harsh-environment deployments such as ports, chemical plants, railways, highways and large outdoor venues.
Why Choose the DS-2DT8C442MXG-LWT
If your site needs a rugged outdoor PTZ that can withstand corrosion, long-range monitoring and low-light conditions, the DS-2DT8C442MXG-LWT is an excellent choice. The 42× optical zoom allows you to perform detailed inspection across large open spaces, while DarkFighter technology ensures usable colour imagery even in minimal light. Its hybrid power illumination system extends performance at night. The polymer anti-corrosion housing and full PTZ mechanics (360° pan, –20° to +90° tilt) make it ideal for demanding installations where durability, clarity and reach matter most.
Key Capabilities
High-Resolution 4 MP Imaging
Captures up to 2560 × 1440 resolution using a 1/1.8″ CMOS sensor, enabling clear identification of people, vehicles and events from moderate to long distances across large areas.
42× Optical Zoom (6.0–252 mm)
The powerful zoom lens offers a wide-angle view of expansive sites and the ability to zoom in to fine detail—perfect for industrial perimeters, infrastructure monitoring or open site security.
Exceptional Low-Light & Hybrid Illumination
With DarkFighter imaging and hybrid lighting that includes IR up to ~500 m and white light up to ~100 m, this camera delivers clear visuals even in challenging lighting or at night.
Full PTZ Coverage & Smart Scan
Provides 360° continuous pan and –20° to +90° tilt (auto-flip), with extensive preset and patrol functions. Ideal for continuous scanning of large zones, infrastructure perimeters or transport hubs.
Rugged Anti-Corrosion Construction
The anti-corrosion polymer housing combined with IP67 rating ensures resistance to dust, water, corrosive atmospheres (e.g., coastal, chemical) and other tough outdoor environments.

Tip:
Use the wide zoom setting when you need to keep track of general activity across a large area; switch to the telephoto end when you wish to inspect specific objects, faces, vehicles or remote targets.
FAQs
- How far can the camera “see” in the dark?
With hybrid illumination this model supports IR visibility up to approximately 500 metres and white-light fill up to ~100 metres, making it ideal for large outdoor sites with minimal ambient lighting.
- Is the camera designed for corrosive environments?
Yes — the anti-corrosion polymer enclosure guards against harsh atmospheres such as coastal salt-spray, chemical exposure or industrial outdoor conditions, extending durability and lifespan.
- Does the “42× optical zoom” mean image quality is maintained at distance?
Yes — optical zoom uses the lens optics to move closer to the subject without degrading image resolution, unlike digital zoom which simply enlarges pixels.
