Hikvision DS-2DF8225IX-AEL(W) 2MP 25× Network IR Speed Dome Outdoor Darkfighter PTZ
The Hikvision DS-2DF8225IX-AEL(W) is an 8-inch 2 MP DarkFighter network speed dome built to watch large, open sites from a single moving camera. A 25x optical zoom reaches distant subjects, DarkFighter low-light technology keeps the image clean in near-darkness, and long-range smart infrared lights the scene at night. Deep-learning analytics detect and auto-track people and vehicles, and a built-in wiper, IP67 housing and IK10 rating handle harsh outdoor conditions.

§ 01Overview
What the 2DF8225IX is
The Hikvision DS-2DF8225IX-AEL(W) is a long-range DarkFighter speed dome made to cover wide perimeters, yards, car parks and public spaces from one moving camera.
A motorised 5.7-142.5 mm lens gives 25x optical zoom, so you can pull a distant subject in close, while continuous 360° endless pan and -20° to 90° tilt let you, or the analytics, steer the view anywhere across the scene.
A 2 MP sensor keeps streaming and storage light for a busy PTZ.
Its strength is seeing at distance in poor light.
DarkFighter low-light technology captures clean, low-noise images in near-darkness, and long-range smart infrared illuminates the scene at night and automatically adjusts its beam angle to match the zoom, so distant subjects stay lit as you zoom in.
Deep-learning analytics detect and auto-track human and vehicle targets - the camera pans, tilts and zooms to follow a target on its own - and it captures faces and supports road-traffic vehicle detection.
A 120 dB WDR handles glare and deep shadow on exposed sites.
Two practical notes so you specify it correctly.
This is a DarkFighter low-light camera that uses infrared at night, so the night picture is black-and-white rather than full colour.
And it is a large 8-inch PTZ that draws real power: plan a Hi-PoE source or a 24 VAC supply rated for the camera, its infrared and its heater, plus a sturdy pole or wall bracket.
A built-in wiper clears rain from the dome, and the IP67, IK10 housing suits demanding outdoor positions.
Record it to a Hikvision NVR that supports PTZ control.

§ 04Why choose this
Built for the way you actually use the 2DF8225IX
See in poor light
DarkFighter imaging and long-range smart infrared keep distant scenes usable after dark.
Hands-free tracking
Deep-learning auto-tracking follows people and vehicles on its own across the scene.
Built for the weather
A built-in wiper plus IP67 and IK10 keep it working on exposed poles and in heavy rain.
§ 05Where it fits
Right at home in these scenarios
Industrial yards and depots
Sweep a large site and zoom in on activity at the far fence line.
Car parks and forecourts
Track vehicles and people across a wide open area from one camera.
Perimeters and boundaries
Watch a long boundary from a single pole-mounted PTZ with auto-tracking.
Public spaces and roads
Cover open civic areas and roadways and zoom in on incidents as they happen.
§ 06Setup
Installation & setup
What's in the box
One DS-2DF8225IX-AEL(W) 8-inch DarkFighter speed dome with mounting hardware and documentation. The Hi-PoE source or 24 VAC power supply, bracket, network cable and any NVR are supplied separately.
Installation requirements
Mount it on a sturdy wall bracket, pole or pendant over the area to cover, allowing for its size and weight. Provide a Hi-PoE source or a 24 VAC supply rated for the camera, its infrared and its heater, connect the network, set the presets, patrols and deep-learning auto-tracking in the software, and add it to a Hikvision NVR that supports PTZ control.
