Hikvision DS-2DE4A425IWG-E 4 MP 25× Network IR PTZ Camera

Need to cover a wide area but still zoom in and actually see what’s happening? The DS-2DE4A425IWG-E gives you crisp 4 MP detail plus a serious 25× optical zoom, so you can monitor large spaces and still pull in faces, vehicles, and activity when it matters. With low-light performance, 120 dB WDR, and up to 50 m IR, it’s built for reliable coverage day or night—without babysitting the camera.

Key Features

  • 4 MP (2560 × 1440) imaging — clearer detail for identifying people/vehicles instead of guessing.
  • 25× optical zoom (4.8 to 120 mm) — zoom in on distant subjects without losing clarity.
  • Powered-by-DarkFighter — stronger low-light performance for night scenes and dim areas.
  • 120 dB WDR — better visibility when headlights, glare, or harsh backlight would normally wash out the image.
  • Up to 50 m IR range — dependable nighttime visibility to help keep coverage consistent after dark.
  • IP66 rated — built to handle outdoor dust and water exposure.
  • Deep learning target classification — focuses on human and vehicle targets to reduce “noise” and improve actionability.
  • PoE (802.3at) — power + data over one cable for cleaner installs and fewer points of failure.

Ideal Applications / Common Uses

  • Perimeter and wide-area monitoring: roads, railways, airports, ports
  • Public spaces: squares, parks, scenic spots, stations
  • Large venues and campuses needing PTZ coverage with zoom-in detail
  • Outdoor sites where weather resistance and night visibility matter
