Product Overview
Built for high-security perimeter and traffic monitoring applications, the DS-2DF8C425MHS-DELW is a 4MP DarkFighterX IR network speed dome that combines long-range night imaging with deep learning analytics in a single weatherproof unit. Featuring dual 1/1.8″ progressive scan CMOS sensors, it achieves colour imaging down to 0.0004 lux and operates at 0 lux with 300m IR illumination, making it suited to environments where darkness is a routine challenge rather than an occasional condition. Equipped with 25x optical zoom and a 5.9 to 147.5mm focal length, it can deliver close-up detail across large outdoor areas without repositioning the camera. It also incorporates face capture, face comparison, and road traffic vehicle detection including licence plate number, vehicle model and vehicle colour recognition. With IP67, IK10, TVS 6K lightning protection, a built-in wiper, heater and demist function, the DS-2DF8C425MHS-DELW is engineered for unattended outdoor operation in demanding Australian conditions.
Key Capabilities
DarkFighterX Dual-Sensor Low-Light Imaging
Two 1/1.8″ progressive scan CMOS sensors deliver colour imaging at 0.0004 lux and monochrome at 0.0001 lux. This dual-sensor architecture captures usable detail in near-total darkness, well beyond what a single-sensor design can achieve at equivalent aperture.
300m IR with 25x Optical Zoom
Smart supplemental IR illumination reaches up to 300m, coordinating with the 25x optical zoom as focal length changes. The 5.9 to 147.5mm lens range allows operators to go from a wide scene overview down to a tight close-up without IR washout at shorter distances.
Full PTZ Automation with 300 Presets
360-degree continuous pan, -20 to 90-degree tilt, up to 300 saved presets, 8 patrol scans, 4 pattern scans and a full suite of park actions allow the dome to cover an entire site automatically. Auto-tracking and manual tracking modes respond to movement without operator input.
Face Capture and Face Comparison
Deep learning algorithms detect, track and capture the best face image from moving subjects. Face comparison then matches captured faces against a stored library, enabling identity-based event review at controlled access points, entry foyers and monitored checkpoints.
Road Traffic Vehicle Detection
Vehicle detection captures licence plate number, vehicle model and vehicle colour from traffic lanes and entry points. This supports evidence-grade footage review and integrates with alarm linkage workflows to trigger recording or PTZ actions on vehicle events.
All-Weather Construction for Exposed Sites
IP67 sealing, IK10 vandal resistance, TVS 6K lightning protection, optical defog, 140dB WDR, EIS image stabilisation, plus a built-in wiper, heater and demist function keep the dome operational across the full -40 to 70-degree Celsius operating range.
Best For
- High-Security Perimeter Monitoring: The 360-degree pan, 300m IR reach and auto-tracking allow a single dome to patrol an extended fence line or boundary and lock onto intruders without manual operator control.
- Traffic and Entry Point Monitoring: Road traffic vehicle detection captures licence plate number, vehicle model and colour, making this dome suited to boom gates, site entries and traffic enforcement applications.
- Controlled Access Face Verification: Face capture and face comparison against a stored library enable identity-based alerts at entry foyers, checkpoints and monitored access corridors where accountability is required.
- Exposed Outdoor Installations: The built-in wiper, heater, demist function and TVS 6K lightning protection allow unattended operation through rain, fog, frost and electrical storms without manual intervention.
- Large-Area Sites with Minimal Camera Count: Patrol scans, pattern scans and 300 configurable presets allow a single DS-2DF8C425MHS-DELW to cover multiple zones across a port, industrial yard or campus that would otherwise require several fixed cameras.
Why Choose the DS-2DF8C425MHS-DELW
Where a standard PTZ with a conventional single sensor struggles in low ambient light, the DS-2DF8C425MHS-DELW uses its DarkFighterX dual 1/1.8″ sensor design to retain colour detail at 0.0004 lux and extend IR coverage to 300m, a combination that most 4MP speed domes at this zoom ratio do not offer. The addition of deep learning face capture, face comparison and road traffic vehicle detection with licence plate, model and colour recognition brings analytical capability that fixed cameras require multiple units to replicate. The full-weather package, including a built-in wiper, heater, demist function and TVS 6K lightning protection, means the dome is genuinely designed for unattended outdoor deployment rather than just rated for it. H.265+ compression with tri-stream output and up to 256GB onboard microSD storage reduce bandwidth and NVR storage demands on large installations. The DS-2DF8C425MHS-DELW is available at Security Wholesalers for integrators and installers working on infrastructure, industrial and high-security commercial projects.
Buyer Decision Tips
Hi-PoE Power Requirement: The DS-2DF8C425MHS-DELW draws up to 62W and requires Hi-PoE (not standard 802.3af/at PoE). Confirm that your switch or injector supplies Hi-PoE before installation. Standard PoE switches will not power this unit, and running a separate 36VDC power supply to the mounting location needs to be factored into your cabling plan.
Face Comparison vs. Vehicle Detection Placement: Face comparison performs best when the dome is positioned to capture subjects at a controlled choke point such as an entry door or boom gate where subjects approach at a predictable distance. Vehicle detection for licence plate capture requires adequate lighting or IR coverage at the lane approach angle. These two analytics serve different zones, so consider whether your site needs one or both functions and plan preset positions accordingly.

Ideal Use Cases
Port and Wharf Perimeter Surveillance
The 300m IR range and 360-degree continuous pan allow a single dome to patrol extended waterfront fence lines and loading zones. The built-in heater, demist and wiper maintain image clarity through salt air, rain and early morning condensation.
Industrial Site Entry and Exit Control
Road traffic vehicle detection captures licence plate number, vehicle model and colour at boom gates and weighbridges. Alarm linkage can trigger PTZ preset moves or recording when an unregistered plate is detected at the entry point.
Airport and Airside Perimeter Monitoring
Intrusion detection, line crossing and auto-tracking ensure that movement across restricted airside boundaries triggers an automated response. The 25x optical zoom allows operators to identify subjects at range before committing to a response.
Correctional and Detention Facility Yards
Face capture at 0.0004 lux colour sensitivity and face comparison against a stored library supports identification in poorly lit exercise yards and corridors without additional lighting infrastructure. IK10 vandal resistance adds physical durability in these environments.
Construction Site Night Patrol
Patrol scans across up to 8 pre-programmed paths with 32 preset positions each allow the dome to automatically sweep a large site footprint during unmanned overnight hours. DarkFighterX imaging maintains usable footage without permanent site lighting.
Traffic Intersection and Road Monitoring
140dB WDR handles the extreme contrast between direct headlights and dark surrounds at night intersections. Vehicle detection with colour, model and plate recognition provides evidence-grade data for traffic incident review and enforcement workflows.
Choosing the Right Model
- Choose this model if: Your site requires long-range IR coverage beyond 150m, face capture with face comparison analytics, road traffic vehicle detection including licence plate recognition, and full all-weather autonomy including wiper, heater and demist in a single outdoor speed dome.
- Choose a different model if: Your installation only requires standard PoE power, as the DS-2DF8C425MHS-DELW demands Hi-PoE at up to 62W and will not operate from a conventional 802.3af/at PoE switch without a dedicated Hi-PoE injector or switch port.
- Choose a different model if: Your application is primarily indoor or in a compact covered area where a fixed wide-angle camera would provide continuous coverage without the added complexity of PTZ patrol programming and a 10kg pole-mount installation.
- Choose a different model if: Your budget is set for a mid-range PTZ and the deep learning face comparison and vehicle detection analytics are not required, as a simpler speed dome with standard motion-based smart events may meet the brief at lower cost.
FAQs
- What makes DarkFighterX different from a standard low-light PTZ camera?
DarkFighterX uses two 1/1.8″ CMOS sensors rather than one. This dual-sensor design enables colour imaging at 0.0004 lux and monochrome at 0.0001 lux, which is significantly lower than what a single-sensor PTZ of comparable focal length achieves. In practical terms, this means the DS-2DF8C425MHS-DELW can retain colour identification detail in near-dark conditions where a standard camera would produce grey monochrome imagery.
- Does the 300m IR range apply at full 25x zoom?
Smart supplement light on the DS-2DF8C425MHS-DELW adjusts IR intensity and angle in coordination with the zoom level, so the illumination pattern narrows as the lens zooms in. The 300m rated IR distance is the maximum reach. At wider zoom positions the effective illuminated area is broader but the IR per unit area is lower. For best results at maximum range, the camera should be positioned with a clear line of sight and minimal atmospheric interference.
- What power supply does the DS-2DF8C425MHS-DELW require, and can I use a standard PoE switch?
This dome requires Hi-PoE capable of delivering up to 62W. Standard IEEE 802.3af (15.4W) and 802.3at (30W) PoE switches are insufficient. You will need a Hi-PoE switch port or a dedicated Hi-PoE injector. Alternatively, 36VDC direct power can be supplied within the +/-25% tolerance. Plan this into your cabling infrastructure before purchase.
- How does face comparison work and does it require a separate server?
The DS-2DF8C425MHS-DELW performs face capture onboard, detecting and grading face images from moving subjects and selecting the best frame. Face comparison then matches captured faces against a pre-loaded face library. This processing is handled within the camera itself for capture and basic comparison. Integration with Hikvision platforms such as HikCentral Pro or iVMS-4200 allows more extensive library management and event reporting.
- Can the dome detect licence plates, and what information does it capture?
Road traffic vehicle detection on the DS-2DF8C425MHS-DELW captures licence plate number, vehicle model and vehicle colour. This is distinct from a dedicated ANPR system and is designed for traffic monitoring and entry-point review rather than high-speed enforcement. Positioning the camera at an appropriate approach angle and ensuring adequate IR illumination at the detection zone will influence recognition accuracy.
- What does the built-in wiper, heater and demist function do for outdoor installations?
The wiper clears rain droplets and surface debris from the dome window, the heater prevents internal condensation and maintains operation in sub-zero conditions, and the demist function clears interior fogging. Together these allow the DS-2DF8C425MHS-DELW to operate continuously in rain, frost and high-humidity coastal environments without manual maintenance between service visits. The operating range is confirmed at -40 to 70 degrees Celsius.
- How many preset positions can the dome store and how are patrol routes configured?
The dome supports up to 300 saved preset positions. Patrol scans allow up to 8 separate patrol paths, each containing up to 32 preset stops. Pattern scans store up to 4 recorded movement paths with over 10 minutes of record time per scan. Park actions can be set to automatically return the dome to a preset, patrol or panorama scan after a defined idle period, keeping the camera actively covering priority zones without operator input.
- Where can I source the DS-2DF8C425MHS-DELW in Australia with technical support available?
The DS-2DF8C425MHS-DELW is supplied through Security Wholesalers, which stocks Hikvision PTZ cameras for professional installers and integrators across Australia. Given the Hi-PoE power requirements, 10kg installation weight and deep learning configuration involved with face library setup and vehicle detection zone mapping, purchasing through a supplier with product knowledge and access to technical documentation is recommended before committing to deployment.
