Product Overview
Wide-area monitoring across large outdoor sites demands a camera that can both survey a broad scene and zoom in sharply on specific targets without losing detail. The DS-2DF8C442IXG-ELW is a 4MP 42x DarkFighter IR Network Speed Dome PTZ built for exactly this role, suited to critical infrastructure, city intersections, large commercial perimeters, and any site where a single fixed camera cannot cover the required ground. Featuring a 42x optical zoom lens with a focal range of 6.5 to 273mm, it can shift from a 65.8-degree wide view down to a 1.6-degree telephoto angle to identify detail at distance. Equipped with Hikvision DarkFighter technology, it delivers colour imaging at illumination levels as low as 0.002 lux, with integrated IR illuminators extending visibility up to 500 metres in total darkness. It also incorporates AcuSense-powered functions including face capture, line crossing detection, intrusion detection, and auto-tracking for intelligent scene management. IP67 weatherproofing and an IK10 vandal-resistant housing make it well suited to exposed outdoor installations operating across a temperature range of -40 to 65 degrees Celsius.
Key Capabilities
42x Optical Zoom with Long Focal Range
The 6.5 to 273mm motorised lens allows operators to shift between wide situational awareness and tight telephoto identification from a single camera position. This eliminates the need for additional fixed cameras at perimeter entry points or monitoring zones.
DarkFighter Low-Light Colour Imaging
DarkFighter technology enables full-colour video at 0.002 lux, allowing the camera to capture usable colour footage in near-dark outdoor conditions before switching to monochrome at 0.0002 lux. This is particularly relevant for poorly lit perimeters, car parks, and industrial yards where colour detail matters for identification.
500 Metre IR Illumination Range
Integrated IR LEDs provide effective illumination up to 500 metres in zero-light conditions. This range supports long-distance coverage of fence lines, open yards, and approach roads without dependence on external lighting infrastructure.
AcuSense Auto-Tracking and Intelligent Detection
AcuSense-powered functions include auto-tracking of moving subjects, intrusion detection, line crossing detection, and face capture. Auto-tracking reduces the need for manual PTZ control and ensures the camera follows a subject of interest automatically across a wide scene.
4MP Resolution at 2560 x 1440
The 1/1.8-inch progressive scan CMOS sensor captures footage at 2560 x 1440 resolution. Combined with the 42x optical zoom, this resolution supports detail identification at extended distances, which is critical for applications such as perimeter monitoring and public space surveillance.
IP67 and IK10 Rated Housing
The speed dome housing carries both IP67 ingress protection against water and dust and an IK10 vandal resistance rating. Paired with an operating temperature range of -40 to 65 degrees Celsius, this makes the unit suitable for exposed rooftop and pole-mounted installations in harsh Australian outdoor conditions.
Best For
- Critical Infrastructure Sites: Airports, power stations, and transport hubs benefit from the 42x optical zoom and auto-tracking, which allow operators to zoom into specific areas while the camera handles subject following automatically.
- Large Perimeter Monitoring: The 500 metre IR range and wide-to-telephoto field of view make this unit effective for covering warehouse perimeters, industrial yards, and fence lines from a single elevated mounting point.
- Urban and Public Space Surveillance: City intersections, public plazas, and transport corridors requiring broad scene overview combined with zoom-in identification capability are a strong match for this camera’s PTZ and DarkFighter combination.
- 24-Hour Outdoor Monitoring: The combination of DarkFighter colour low-light imaging and integrated 500 metre IR illumination means this camera maintains effective coverage whether operated during daylight or total darkness.
- Harsh-Environment Installations: With IP67 weatherproofing, IK10 impact resistance, and a temperature rating down to -40 degrees Celsius, this speed dome is well suited to exposed installations in challenging climates or high-risk vandalism environments.
Why Choose the DS-2DF8C442IXG-ELW
The DS-2DF8C442IXG-ELW stands apart from entry-level PTZ cameras through its combination of a 42x optical zoom lens, a large 1/1.8-inch sensor, and DarkFighter low-light imaging that delivers usable colour footage at 0.002 lux. A basic PTZ camera with a smaller sensor and shorter zoom range cannot replicate the identification capability this unit provides at 200 to 500 metres. The 500 metre IR illumination range is also substantially longer than that offered by mid-range speed domes, which typically cap at 100 to 200 metres. AcuSense auto-tracking reduces the operator workload on large sites by following moving subjects without manual joystick input. H.265+ compression minimises storage and bandwidth impact despite the 4MP resolution output. Available through Security Wholesalers, the DS-2DF8C442IXG-ELW is suited to integrators and end users specifying PTZ coverage for large-scale commercial, government, or infrastructure projects where a single high-performance unit must carry significant monitoring responsibility.
Buyer Decision Tips
Power Supply Requirement: The DS-2DF8C442IXG-ELW requires either 36 VDC or PoE+ (IEEE 802.3at) power. Standard PoE (802.3af) is not sufficient. Confirm that your network switch or PoE injector supports PoE+ output before ordering, as standard PoE switches will not power this unit correctly. If running PoE+ over Cat cable, keep cable runs within the 100 metre IEEE limit to maintain power delivery at full specification.
Lead Time Planning: This model carries a 6 to 8 week lead time. For time-sensitive project installations at critical infrastructure or government facilities, factor this into procurement scheduling and avoid ordering against tight commissioning deadlines without confirming current stock availability in advance.

Choosing the Right Model
- Choose this model if: Your site requires a single PTZ camera to cover large outdoor areas, with the ability to zoom to 500 metres in darkness using integrated IR, and you need AcuSense auto-tracking and face capture to reduce operator workload in wide-scene monitoring scenarios.
- Choose a different model if: Your application is a smaller domestic or small commercial site where the 42x optical zoom and 500 metre IR range exceed what is needed. A fixed-lens turret or dome camera will deliver better value for coverage areas under 30 metres, and the PoE+ power requirement of this unit may also exceed what smaller site switch infrastructure can supply.
- Choose a different model if: Your project timeline cannot accommodate the 6 to 8 week lead time on this unit and requires immediate dispatch. Consider whether a shorter-range PTZ with confirmed in-stock availability would be sufficient for the site’s monitoring requirements.
FAQs
- What optical zoom range does the DS-2DF8C442IXG-ELW provide, and what does this mean in practice?
The camera provides 42x optical zoom across a focal range of 6.5 to 273mm. At the wide end, the field of view is 65.8 degrees, suitable for scanning a large scene. At full telephoto, the field of view narrows to 1.6 degrees, enabling operators to identify detail on subjects or vehicles at ranges of several hundred metres. Digital zoom extends this further to 16x, though optical zoom maintains better image quality. - How does DarkFighter technology affect night-time performance on this camera?
DarkFighter technology, combined with the large 1/1.8-inch sensor, allows the DS-2DF8C442IXG-ELW to produce full-colour video at illumination levels as low as 0.002 lux. This means the camera can capture colour detail in conditions where most cameras would switch to monochrome. At 0.0002 lux, it transitions to black-and-white, and with IR active, it operates in complete darkness with up to 500 metres of IR illumination. - What power supply does this speed dome require, and will a standard PoE switch work?
The DS-2DF8C442IXG-ELW requires either 36 VDC or PoE+ compliant with IEEE 802.3at. Standard PoE (IEEE 802.3af) delivers insufficient power for this unit. You must use a PoE+ capable switch or a dedicated PoE+ injector. Verify your network infrastructure supports 802.3at before installation to avoid powering issues on site. - What intelligent detection and tracking features are built into this camera?
The camera includes AcuSense-powered functions: auto-tracking of moving subjects, intrusion detection, line crossing detection, and face capture. Auto-tracking is particularly relevant for large outdoor sites as it enables the camera to follow a moving subject automatically without operator input, maintaining zoom focus on the target as it moves across the scene. - Is this camera suitable for installation in harsh outdoor environments in Australia?
Yes. The housing is rated IP67 for dust and water ingress protection and IK10 for impact and vandal resistance. The operating temperature range of -40 to 65 degrees Celsius covers the temperature extremes encountered across Australian climates, including exposed rooftop or pole-mounted installations in both alpine and hot arid regions. - What video compression does this camera support, and does it affect storage requirements?
The DS-2DF8C442IXG-ELW supports H.265+, H.265, H.264+, and H.264 compression. H.265+ delivers the most efficient compression, significantly reducing storage and network bandwidth compared to H.264 at equivalent visual quality. For large-scale installations recording continuously from multiple PTZ cameras, selecting H.265+ on compatible NVRs will have a meaningful impact on storage costs. - Where can I purchase the DS-2DF8C442IXG-ELW and what is the lead time?
The DS-2DF8C442IXG-ELW is available through Security Wholesalers.
