Product SKU: DS-2DE4A425IWG1-E
Product Overview
The Hikvision DS-2DE4A425IWG1-E is a 4 MP outdoor AcuSense network speed dome designed for wide-area surveillance where operators need fast PTZ movement, long-range optical zoom and intelligent target filtering. Its 1/2.8-inch progressive scan CMOS sensor captures up to 2560 × 1440 resolution, while the 4.8–120 mm motorised lens provides 25× optical zoom and 16× digital zoom for moving between broad scene coverage and tightly framed distant subjects. Powered-by-DarkFighter low-light performance, 120 dB WDR and up to 50 m IR illumination help maintain usable detail across challenging day and night conditions. Deep-learning human and vehicle classification, smart tracking, face capture and regional people-counting functions add intelligent monitoring capabilities beyond conventional PTZ operation.
Key Capabilities
25× Optical Zoom
The 4.8–120 mm motorised lens provides 25× optical zoom, allowing operators to move from wider scene coverage to detailed views of distant subjects across expansive surveillance areas.
AcuSense Human & Vehicle Classification
Deep-learning target classification helps the camera focus supported alarms on human and vehicle activity, reducing the impact of less relevant movement within monitored areas.
DarkFighter Low-Light Performance
Powered-by-DarkFighter technology supports colour imaging down to 0.005 lux and black-and-white imaging down to 0.001 lux before infrared illumination is required.
High-Speed PTZ Movement
Pan speed is configurable up to 300°/s with 350°/s preset movement, while tilt reaches up to 160°/s with 200°/s preset movement for rapid repositioning between areas of interest.
50 m Smart Infrared
Smart 850 nm infrared illumination reaches up to 50 metres and supports 0 lux operation with IR active for dependable night surveillance.
Smart Tracking & Face Capture
Manual and automatic tracking are supported, while face capture can detect up to five faces simultaneously and output the best captured face image for supported applications.
Best For
- Large Commercial Properties: Fast PTZ movement and 25× optical zoom allow operators to investigate activity across expansive sites.
- Roads and Transport Areas: Long-range zoom, tracking and intelligent target classification suit roads, terminals and transport infrastructure.
- Industrial Yards: AcuSense filtering and 50 m IR help monitor people and vehicles across loading and operational areas.
- Public Spaces: Smart tracking, face capture and regional people-counting functions support more advanced monitoring in plazas, parks and large venues.
- Outdoor Perimeters: IP67 protection and electrical surge protection suit exposed installations when the complete mounting and cabling system is correctly designed.
Why Choose the DS-2DE4A425IWG1-E
The DS-2DE4A425IWG1-E combines responsive PTZ control, 25× optical zoom and intelligent AcuSense analytics in a compact 4 MP speed-dome platform. Its DarkFighter low-light performance, 120 dB WDR and 50 m IR help maintain visibility across difficult lighting conditions, while 300 presets, patrols, patterns and scheduled PTZ actions support both active operator use and automated surveillance routines. Smart tracking, face capture and regional people-counting add another layer of intelligence beyond basic PTZ movement. Available through Security Wholesalers, it is particularly well suited to large sites where operators need to move quickly between distant areas while filtering alerts around people and vehicles.
Buyer Decision Tips
Buyer Tip: The 25× optical zoom delivers much tighter long-range framing than a fixed camera, but image detail at distance still depends on installation height, scene lighting, atmospheric conditions and how much of the frame the target occupies.
Buyer Tip: The camera supports both 12 VDC and PoE+ power with a maximum draw of 24 W. Check the PoE budget, cable length and switch capability before installation, particularly where the camera will operate continuously with IR, tracking and frequent PTZ movement.

Choosing the Right Model
- Choose this model if: You need a compact 4 MP network PTZ with 25× optical zoom, AcuSense classification, smart tracking and up to 50 m IR.
- Choose a fixed camera if: The site only needs a permanently framed view and operator-controlled pan, tilt and optical zoom are unnecessary.
- Choose a longer-range PTZ if: The camera must illuminate or resolve activity significantly beyond the DS-2DE4A425IWG1-E’s 50 m IR range and 120 mm telephoto focal length.
- Check mounting accessories if: The camera will be wall, pendant, junction-box or in-ceiling mounted, as Hikvision specifies different compatible accessories for each mounting method.
FAQs
- What resolution does the Hikvision DS-2DE4A425IWG1-E provide?
The Hikvision DS-2DE4A425IWG1-E captures up to 2560 × 1440 resolution from a 1/2.8-inch progressive scan CMOS sensor. The current datasheet lists up to 50 fps at 4 MP in 50 Hz systems and up to 60 fps in 60 Hz systems, providing smoother motion capture than many conventional 25 fps PTZ cameras while retaining 4 MP image detail.
- How much zoom does the DS-2DE4A425IWG1-E provide?
The camera uses a 4.8 mm to 120 mm motorised lens with 25× optical zoom and 16× digital zoom. Its horizontal field of view changes from approximately 53.3 degrees at the wide end to 2.6 degrees at telephoto, allowing operators to switch between broad area monitoring and tightly framed long-distance views.
- How far can the infrared illumination reach?
The DS-2DE4A425IWG1-E provides smart infrared illumination up to 50 metres using 850 nm IR. The camera can operate at 0 lux with IR enabled, while DarkFighter low-light performance reaches 0.005 lux in colour and 0.001 lux in black and white before infrared illumination is required.
- What AcuSense and tracking features does the DS-2DE4A425IWG1-E support?
The camera supports deep-learning human and vehicle classification together with manual and automatic smart tracking. Smart events include line crossing, intrusion, region entrance and exiting, unattended baggage and object removal detection. It also supports face capture of up to five faces simultaneously and regional people-counting functions across up to eight detection regions.
- Can the DS-2DE4A425IWG1-E be used outdoors?
Yes. The DS-2DE4A425IWG1-E is rated IP67 and operates from -30°C to 65°C. Hikvision also specifies TVS 6000 V lightning protection together with surge and voltage-transient protection. For Security Wholesalers installations, the mounting accessory, cable entry, PoE budget and supporting structure should still be selected to suit the actual outdoor location.
- What power and storage options does the DS-2DE4A425IWG1-E support?
The camera can operate from 12 VDC or PoE using IEEE 802.3at, with a maximum stated power consumption of 24 W. It also includes a built-in microSD, microSDHC and microSDXC card slot supporting up to 512 GB, together with NAS storage and Automatic Network Replenishment for supported recording systems.
