Product Overview
The Hikvision DS-2DE7A425IWG1-E is a 4MP 25x network speed dome built for wide-area outdoor surveillance where operators need both broad situational awareness and the ability to inspect distant detail. Its 4.8-120 mm motorised lens provides 25x optical zoom, while up to 200 m IR illumination supports extended night coverage. Powered-by-DarkFighter low-light imaging is combined with HIK AI-ISP technology for improved noise reduction, and self-learning focus technology is designed to keep the image clear as the camera changes position or zoom level. AcuSense deep learning focuses supported alarms on human and vehicle targets, while smart tracking, face capture, regional people counting, and compatibility with Hikvision AcuSeek and AcuSearch technologies provide additional tools for live monitoring and post-event review. The camera also includes arrayed dual microphones, a built-in speaker, white flashing light, Hi-PoE support, microSD storage up to 512 GB, and an IP67/IK10-rated housing for demanding outdoor installations.
Key Capabilities
25x Optical Zoom for Wide-Area Monitoring
The 4.8-120 mm motorised lens moves from a 55° horizontal field of view at the wide end to approximately 2.65° at full telephoto. This gives operators the flexibility to survey a broad scene and then optically zoom into a specific gate, vehicle, boundary, or area of concern without relying on digital cropping alone.
Powered-by-DarkFighter with HIK AI-ISP
The 1/2.8″ progressive-scan CMOS sensor is supported by Powered-by-DarkFighter low-light technology and HIK AI-ISP processing. Together with 120 dB WDR, 3D DNR, HLC, BLC, digital defog, and electronic image stabilisation, the camera is designed to maintain useful image quality across difficult lighting conditions.
Up to 200m IR Night Coverage
Integrated infrared illumination supports an IR distance of up to 200 metres. This gives the PTZ extended night-view capability for large outdoor areas such as yards, roads, transport facilities, perimeters, and open public spaces.
AcuSense Human and Vehicle Classification
Hikvision AcuSense technology uses deep learning to focus supported alarm events on human and vehicle targets. This helps improve alarm efficiency by reducing attention given to irrelevant movement and allows operators to prioritise the event types that matter most.
Fast Focus and Smart Tracking
Self-learning focus technology is designed to maintain fast, clear focus during PTZ operation. The camera supports manual tracking and auto-tracking, plus 300 presets, 8 patrols, 4 pattern scans, scheduled tasks, park actions, and 3D positioning for flexible operator control and automated patrol routines.
Built-In Audio and Audio-Visual Alarm
Two built-in array microphones support real-time audio capture, while the built-in speaker has an effective distance of up to 30 metres. Supported events can trigger audible warnings and white light flashing, providing an on-site audio-visual response without requiring a separate speaker at the camera position.
Best For
- Industrial Yards and Logistics Sites: Use the 25x optical zoom and PTZ presets to inspect gates, loading zones, vehicle routes, and distant parts of a large open site from a flexible elevated viewpoint.
- Roads, Railways and Transport Facilities: High-speed pan and tilt, smart tracking, long-range IR, and human/vehicle classification support active monitoring across large transport environments.
- Perimeter and Critical Infrastructure Monitoring: IP67 weather protection, IK10 impact resistance, 6000 V TVS lightning protection, surge protection, and voltage transient protection suit exposed outdoor installations.
- Public Spaces, Parks and Venues: 360° continuous pan, patrol functions, face capture, and regional people counting provide multiple monitoring options for large dynamic spaces.
- Sites Using Compatible Hikvision NVR Search Tools: Compatibility with AcuSeek and AcuSearch technologies can improve playback and event-search efficiency when the camera is used with supported Hikvision recording equipment.
Why Choose the DS-2DE7A425IWG1-E
The DS-2DE7A425IWG1-E is designed for applications that need more than basic PTZ movement. It combines a 4MP sensor, 25x optical zoom, up to 200 m IR, Powered-by-DarkFighter imaging, HIK AI-ISP processing, fast self-learning focus, and AcuSense human and vehicle classification in a single Pro Series speed dome. Compared with a basic long-range PTZ, it adds a broader set of intelligent and operational tools, including manual and auto-tracking, face capture, regional people counting, built-in dual microphones, a built-in speaker, white light flashing, AcuSeek and AcuSearch compatibility, and local microSD storage up to 512 GB. The IP67 and IK10 housing, Hi-PoE power option, and surge protection make it particularly suitable for exposed outdoor sites where reliability and flexible long-range monitoring are priorities.
Buyer Decision Tips
Power Supply Planning: The DS-2DE7A425IWG1-E supports Hi-PoE or 36 VDC ± 25% and has a maximum power consumption of 42 W. Do not assume that a standard 802.3af PoE port or ordinary 802.3at PoE+ port will be suitable. Confirm that the selected Hikvision NVR, PoE switch, injector, or local power supply is specifically compatible with the camera’s Hi-PoE and power requirements before installation.
PTZ Coverage Planning: A PTZ camera can only view one direction in detail at a time. For critical areas that must be recorded continuously, use fixed cameras for permanent coverage and use the DS-2DE7A425IWG1-E for patrols, tracking, verification, and long-range inspection. Presets and patrol routes can automate movement between important viewpoints, but they do not replace simultaneous fixed coverage of every direction.
Zoom and Identification Planning: The 25x optical zoom provides substantially more detail at distance than the wide setting, but actual identification performance depends on lighting, target size, movement, atmospheric conditions, mounting stability, and the selected zoom level. Plan camera placement around the actual detection, observation, recognition, or identification requirement rather than using the 200 m IR figure as an identification-distance guarantee.
