Overview:

Hikvision DS-2DE5425IWG1-E 4MP 25X DarkFighter AcuSense Network Speed Dome
The Hikvision DS-2DE5425IWG1-E is a professional 4MP network speed dome camera designed for detailed monitoring across large areas. With 25x optical zoom, long-range infrared illumination and intelligent AcuSense technology, it provides clear video coverage during both daytime and low-light conditions. The 4MP resolution delivers detailed images, while the powered PTZ design allows users to monitor wide areas and zoom in on important activity when required.

Description:

This Hikvision 4MP PTZ security camera combines DarkFighter imaging, AcuSense target classification and powerful zoom capabilities in a single surveillance solution. Its 25x optical zoom allows distant objects to be viewed in greater detail, while up to 150 m IR illumination extends monitoring capability into dark environments. HIK AI-ISP technology helps reduce image noise, and self-learning focus technology maintains sharp images as the camera moves between viewing areas.

The camera is well suited to applications requiring reliable monitoring over expansive areas, including commercial properties, industrial sites, perimeter security and other demanding surveillance environments. Smart tracking, face capture and human and vehicle classification help make it easier to identify relevant activity and reduce unnecessary alerts.

Features:

Clear 4MP Imaging and Long-Range Zoom
The 1/2.8-inch progressive scan CMOS sensor produces 2560 x 1440 resolution for detailed surveillance footage. The 4.9 mm to 120 mm lens provides a flexible viewing range, while 25x optical zoom can bring distant subjects closer without relying solely on digital enlargement.

For additional viewing flexibility, the camera also provides up to 16x digital zoom. Fast focusing and self-learning focus technology help maintain image clarity while the speed dome changes position or zoom level.

Night Surveillance with DarkFighter and IR
The camera is designed for demanding low-light surveillance. DarkFighter imaging technology, HIK AI-ISP noise reduction and up to 150 m infrared illumination help produce usable images when ambient lighting is limited.

Image processing also includes:

• 120 dB wide dynamic range for scenes with strong differences between bright and dark areas
• 3D DNR for reducing image noise
• Digital defog for improved visibility in hazy conditions
• BLC and HLC for challenging lighting situations
• Electronic image stabilization for reducing the effect of camera movement
• Regional exposure and regional focus for more controlled image adjustment

AcuSense Intelligent Monitoring
AcuSense technology uses deep learning to classify human and vehicle targets, helping security teams concentrate on activity that is more likely to be relevant. The camera also supports smart events, motion detection, face capture and smart tracking for more advanced surveillance applications.

The camera supports 8 fixed regions of interest, allowing selected areas to receive greater attention during monitoring or recording. It can also provide up to 20 simultaneous live views.

Network, Audio and Alarm Connectivity
The Hikvision speed dome connects through a 10/100 Mbps self-adaptive RJ45 Ethernet port and supports both 36 VDC and PoE using the 802.3at standard. A built-in memory card slot provides local storage capability, while audio and alarm connections allow the camera to integrate with wider security systems.

Key connectivity and control points include:

• 1 x RJ45 10M/100M self-adaptive Ethernet port
• Built-in memory card slot
• 1 x line-in audio input
• 1 x line-out audio output
• 2 x alarm inputs
• 1 x alarm output
• 36 VDC power support
• PoE 802.3at support
• Support for Hikvision network speakers and network microphones

Video and Surveillance Performance
The camera supports H.265+, H.265, H.264+ and H.264 video compression, helping balance image quality with network bandwidth and storage requirements. It is also designed to work with compatible Hikvision NVR systems and supports AcuSeek and AcuSearch technologies for improved searching and playback efficiency.
