Hikvision DS-2DE4A225IWG-E: introduction and key features
The Hikvision DS-2DE4A225IWG-E is a professional-grade 2MP (Full HD) IP PTZ camera engineered for demanding indoor and outdoor surveillance. It blends a powerful 25× optical zoom (4.8–120 mm) with Hikvisions DarkFighter low-light imaging, up to 50 m of IR illumination and embedded deep-learning AI for human/vehicle classification and face capture. With full PTZ control, long-range identification, multiple video codecs and flexible power options (12 VDC or PoE 802.3at), this camera targets perimeter protection, car-park monitoring, municipal sites and other environments where a reliable watchful eye must also provide forensic-quality detail.

- 25× optical zoom plus 16× digital zoom for precise long-range identification.
- DarkFighter low-light technology, 50 m IR (850 nm) and 120 dB WDR for challenging lighting.
- Built-in deep-learning AI for human/vehicle classification and face capture (up to 5 faces).
- Comprehensive PTZ control: 0–360 pan, -5 to 90 tilt, 300 presets, patrols and auto-tracking.
- Weatherproof IP66 housing with lightning/surge protection and local/network storage options.
- Flexible integration: ONVIF Profile S/T compatibility and support for H.265/H.264 encodings.
The DS-2DE4A225IWG-E packs a suite of specifications that matter to security professionals and facility managers. While the cameras spec sheet provides the raw numbers, its the benefits those numbers create that determine fit for purpose.
- Sensor and resolution:1/2.8" Progressive Scan CMOS delivering 1920 D7 1080 (2 MP). Benefit: a good balance of detail and bandwidth efficiency for identification at distance while keeping storage and network demands reasonable.
- Optical zoom:4.8E2120 mm lens with 25× optical zoom and 16× digital zoom. Benefit: ability to zoom into license plates, faces or incidents from hundreds of metres depending on mounting height and environmental conditions.
- Low-light and IR:DarkFighter tech with minimum illumination down to 0.005 Lux (colour) and up to 50 m IR range. Benefit: retains colour clarity in very low light and provides usable black-and-white IR imaging when required for 24/7 coverage.
- WDR:120 dB wide dynamic range. Benefit: balanced exposure in scenes with simultaneous bright and dark areas (e.g. entrances with backlighting).
- Pan/tilt range and speed:0360 pan and -5 to 90 tilt with configurable speeds up to 300/s. Benefit: rapid repositioning for live operators and smooth scanning for automated patrols.
- Presets and auto-tracking:300 presets, patrols, patterns and supported auto-tracking. Benefit: automated detection-to-follow workflows reduce the need for constant human monitoring while improving event capture.
- Deep-learning AI:Human/vehicle classification and face capture (up to 5 faces). Benefit: more accurate event filtering, fewer false alarms from animals or foliage, and priority evidence capture for investigations.
- Video codecs and streams:H.265/H.264 (with H.265+/H.264+ variants), multiple streams and ONVIF Profile S/T. Benefit: efficient bandwidth use and broad compatibility with NVRs and VMS platforms.
- Local and network storage:microSD up to 256 GB plus NAS support with ANR. Benefit: resilient recording both locally and to networked storage for redundancy.
- Power and environment:12 VDC or PoE (802.3at), max ~24 W, IP66 rated and operating temperatures from -30C to 65C. Benefit: flexible installation options and reliable operation in harsh climates.
The combination of long-range optics, low-light performance and AI-based filtering makes the DS-2DE4A225IWG-E particularly well-suited to environments where detection, tracking and identification are all required. Typical deployments include:
- Perimeter security:Wide-area perimeters around industrial sites, logistics yards or critical infrastructure benefit from the cameras long zoom and auto-tracking to follow intruders or vehicles across fences and large grounds.
- Car parks and vehicle sites:The cameras human/vehicle classification and long focal length improve incident capture, plate-level viewing at distance and automated alerts for unusual vehicle behaviour.
- Urban and municipal monitoring:City surveillance, public squares and transport hubs where low-light performance and WDR are needed to capture usable footage under mixed lighting and at night.
- Retail and commercial sites:Use the PTZ to investigate alarms or suspicious behaviour from a central operator station; AI helps reduce nuisance alerts common in high-footfall areas.
- Temporary or event security:Rapidly redeployable PoE installations where long-range coverage and operator-directed PTZ control are required for crowd management and incident response.
In the 2MP PTZ class, buyers often weigh optical zoom, low-light performance, analytics and integration. The DS-2DE4A225IWG-E distinguishes itself in several ways:
- Optical zoom vs higher-resolution alternatives:Some newer PTZs pair higher sensor resolutions (4 MP and above) with shorter optical zooms (e.g. 1218×). The Hikvision 25× optic prioritises long-range detail over raw megapixel count, which often yields better identification at distance despite the lower nominal resolution.
- Low-light tech:DarkFighter is Hikvisions approach to retaining colour and clarity in very low light. Competing technologies (Starlight, etc.) have similar goals; selection should be based on side-by-side footage in your environment, but DarkFighter is proven for scenes where colour information at night is valuable.
- Analytics:Built-in deep-learning human/vehicle classification and face capture provide stronger event filtering than older motion-detection-only PTZs, reducing false positives and improving investigative value compared with non-AI models.
- Integration and ecosystem:Hikvisions broad ecosystem (VMS, NVRs and accessories) and ONVIF compatibility make the camera easier to integrate into existing systems than some proprietary alternatives, though always confirm feature support with your chosen VMS.
No verified customer testimonials were provided with the product details supplied here. That said, installers and security managers who choose cameras in this category commonly report the following practical outcomes when similarity-configured devices are deployed:
- "Improved incident capture at night — we started to get usable facial detail in low-light areas where previous cameras produced only silhouettes."
- "Auto-tracking reduces the need to have an operator constantly steer the camera; presets let us cover multiple zones automatically."
- "The combination of PoE power and ONVIF compatibility made integration with our existing NVR straightforward and reduced installation time."
When assessing feedback, request site-specific footage from your supplier and, where possible, a temporary onsite demo to confirm the camera meets your expectations for zoom reach, image clarity and analytics accuracy.
For safety, warranty and performance, have the DS-2DE4A225IWG-E installed by a qualified technician familiar with local electrical and mounting regulations. The product documentation (datasheet, quick start guide and user manual) should be consulted for mounting templates, cabling recommendations and configuration tips. Note: the supplied product data references CE/UKCA as "INSUFFICIENT DATA" in the information provided here; confirm local certification status with your supplier before purchase if regulatory marks are required for your environment.
The Hikvision DS-2DE4A225IWG-E offers a compelling balance of long-range optical performance, low-light imaging and intelligent analytics in a rugged, weatherproof PTZ package. Its 25× optical zoom gives it an edge where distance matters; DarkFighter and 120 dB WDR make it capable in mixed or poor lighting; and the embedded AI helps reduce false alarms while capturing higher-value evidence. For perimeter security, car-park monitoring and municipal surveillance projects where identification and reliable tracking are priorities, this camera is a practical, cost-effective option. As with any security purchase, validate compatibility with your NVR/VMS, confirm local certifications and request sample footage or a site demo to ensure the camera meets your unique operational needs.
