Hikvision DS-2DF8442IXS-AELY(T5) 4MP AcuSense 42X DarkFighter IR Network Speed Dome, Face Capture & Deep Learning, 42x Optical Zoom, IR 400m

Product SKU: DS-2DF8442IXS-AELY(T5)

Product Overview

The DS-2DF8442IXS-AELY(T5) is a high-end 4 MP Ultra-Series PTZ speed dome from Hikvision designed for large-scale, mission-critical surveillance. Featuring a 1/1.8″ progressive-scan CMOS sensor delivering up to 2560 × 1440 resolution, combined with a 42× optical zoom (6.0–252 mm) and 16× digital zoom, it provides exceptional reach and clarity across expansive sites. Incorporating DarkFighter ultra-low-light technology and Smart IR up to ~400 m, along with IP67 / IK10 rated housing (excluding dome), this model is engineered for demanding environments such as airports, seaports, transport hubs and outdoor industrial perimeters.

Why Choose the DS-2DF8442IXS-AELY(T5)

If you need a PTZ camera that combines long-range zoom, outstanding clarity in very low light, advanced analytics and a rugged build for continuous outdoor operation, the DS-2DF8442IXS-AELY(T5) stands out. Its 42× optical zoom allows monitoring of vast perimeters or open areas and then zooming in to inspect fine detail. DarkFighter technology ensures usable colour imagery in near darkness and the inclusion of Smart IR expands coverage at night. With full 360° pan, –20° to +90° tilt (auto-flip), and support for face capture and traffic/vehicle detection, this model is ideal for high-risk, harsh-environment deployments where reliability and performance matter most.

Key Capabilities

 

Key Features

• 4 MP (2560 × 1440) resolution: Provides high-definition imagery suitable for identification and detailed monitoring across large-site coverage areas where clarity matters.

• 42× optical zoom + 16× digital zoom: Enables dramatic flexibility—capture broad scene then zoom in for detailed inspection of distant subjects—ideal for expansive outdoor or industrial environments.

• 6.0–252 mm motorised lens: Covers approximately 56.6° wide-angle down to ≈ 1.7° telephoto field of view, enabling both broad situational awareness and focused detail.

• DarkFighter technology + low-light limits: Capable of capturing usable colour in very low ambient light (Colour: ~0.001 Lux @ F1.2, B/W: ~0.0005 Lux @ F1.2) and remains effective with IR support to extend night-time visibility.

• 360° pan / –20° to +90° tilt with auto-flip: Ensures full scene coverage including overhead and downward view capability—essential for open-site surveillance and dynamic zones.

• Smart IR up to ~400 m + face/vehicle analytics: Supports smart illumination and edge analytics (face capture, vehicle/traffic detection), enabling proactive security in transport hubs, perimeters, and high-risk sites.

Ideal Use Cases

• Airports & Seaports – Efficiently covers large outdoor terminals, aprons and sea-side perimeters with long-range zoom and low-light clarity.
• Industrial and Critical Infrastructure Sites – Rugged build and advanced analytics support harsh environments like plant yards, power stations or exposed perimeters.
• Transport Hubs & Highways – Super-zoom, tracking and vehicle/traffic detection make it ideal for monitoring transit corridors, roads and open public spaces.
• City Surveillance / Public Spaces – Large open venues, plazas or intersections where both wide-angle situational coverage and detailed zoom are required.
• Coastal / Harsh-Environment Installations – With optional corrosion-resistant features and robust enclosure, it suits outdoor deployment in challenging weather or salt-air zones.

 

Choosing Between Wide and Tele Zoom Settings

The DS-2DF8442IXS-AELY(T5) supports a motorised zoom from 6.0 mm (wide) to 252 mm (tele). At the wide-end you gain approximately 56.6° horizontal field of view — ideal for broad area monitoring. At the tele-end (~252 mm) the horizontal field tightens to ~1.7°, ideal for detailed inspection of distant access points or subjects.

Lens Setting	Approx. Horizontal FOV	Best For
6.0 mm	≈ 56.6°	Broad-area monitoring, building perimeters, open yards
252 mm	≈ 1.7°	Distant subjects, vehicle lanes, detailed inspection

Tip:
Choose the wide setting when you want full scene coverage; switch to telephoto when you need to focus on detail or identify specific targets.

 

FAQs

1. How far can it see at night?
   This model supports Smart IR illumination of up to approximately 400 metres in low-light or no-light conditions, allowing visibility deep across open-site areas. The exact distance achievable depends on site conditions, reflectivity of objects, and weather/pollution levels.
2. What is DarkFighter technology?
   DarkFighter is Hikvision’s advanced low-light imaging technology built into this model, enabling still usable colour imagery under extremely low ambient illumination (Colour: ~0.001 Lux, B/W: ~0.0005 Lux). It allows detection and identification when many standard cameras would turn to monochrome or fail to capture meaningful detail.
3. Is this camera suitable for harsh outdoor or corrosive conditions?
   Yes — the DS-2DF8442IXS-AELY(T5) has IP67 and IK10 ratings (dome excluded), plus is designed for operation from –40 °C to +70 °C. This makes it very suitable for exposed outdoor environments such as coastal sites, industrial plants or transport infrastructure that demand high durability and reliability.
