Hikvision DS-2DF8442IXG1-ELWY 4MP PTZ DarkFighter speed dome 42× zoom IR 400 m

PTZ surveillance camera for large areas

DS-2DF8442IXG1-ELWY is an advanced PTZ camera that can pan, tilt and zoom to monitor very large areas from a single installation point. The camera can be controlled manually by an operator or automatically follow incidents using intelligent features.

The powerful zoom allows the camera to be placed far from the monitored area while still identifying details.

4 MP image sensor

The camera features a 4 MP sensor that delivers sharp, detailed images. The resolution makes it possible to digitally zoom into recordings without losing too much detail, which is important when monitoring larger areas.

The image sensor works together with the camera's optics and image processing to ensure stable images both day and night.

42× optical zoom

The powerful optical zoom lets you get very close to objects at long distances. That means the camera can cover large areas while still identifying details like people or vehicles.

Optical zoom preserves image quality because the magnification happens in the optics rather than digitally.

DarkFighter technology for low light

DarkFighter technology is designed to deliver clear images in very low light. The camera can continue to provide usable color images in situations where ordinary cameras have already switched to night mode.

It’s especially useful in areas with limited lighting where you still want to see details.

Infrared night illumination up to 400 meters

The camera has powerful infrared lighting, allowing monitoring in complete darkness. The long range makes it suitable for large areas like ports, industrial sites and long access roads.

Intelligent light control automatically adjusts the strength so nearby objects are not overexposed.

Wide Dynamic Range

The camera supports advanced dynamic range processing to handle strong differences in scene brightness. This means both bright and dark areas can be shown clearly in the same image.

The feature is particularly useful at entrances, gates and locations with strong backlight.

PTZ movement and automatic patrols

The camera can rotate 360 degrees and move vertically to cover a wide surveillance area. It can store many positions and automatically move between them in preset patrols
This allows monitoring of multiple areas with one camera without constant manual control.

Intelligent perimeter protection

The camera supports intelligent analytics that can detect when people or vehicles enter defined areas. The system can, for example, detect line crossing or intrusion into a fenced zone.

By filtering events based on object type, false alarms from animals or moving objects can be reduced.

Face detection

The camera can detect and store images of faces when people move through the monitored area. The system automatically selects the best image during movement.
These images can be used later for searching or analysis in the surveillance system.

Vehicle analysis and license plate recognition

The camera can analyze vehicles in the monitored area and record details such as vehicle type, color and direction of travel. At checkpoints, the camera can also capture license plates.
This can be used for access control, traffic monitoring or recording vehicles across large areas.

Automatic tracking

The camera can automatically follow people or vehicles as they move through the monitored area. The camera zooms in and tracks the object so the operator gets a clear view of the incident.

This provides better situational awareness when objects move across a large area.

Network and integration

The camera can be integrated with Hikvision surveillance systems and also supports standard protocols for integration with other systems. It can be accessed via software, mobile app and web browser.
This makes it suitable for both small and very large surveillance solutions.

Power over Ethernet

Do like the professionals. POE means that only one cable is needed for the camera. The camera gets power through the network cable, typically from a recorder with built-in PoE, or from a POE switch.

Audio Trigger

Univiews cameras with microphone can also respond to what they don't see. For example, it can be cries or screaming on a women's toilet if you place the camera outside the door.

PTZ

Stands for Pan, Tilt and Zoom and means the camera can turn right and left, up and down and zoom in to get the best pictures.
You can control it from your mobile, computer or even a joystick. The camera can also be set to constantly patrol between fixed points.

Autotracking

PTZ cameras may have built-in intelligence and keep an eye for you. If something happens that the camera assesses is interesting, it will immediately zoom in and follow the object.

Alarm in/out

Start shooting when the alarm goes or a door is opened - and use the image analyzes to control your Philips Hue or open a port.
Alarm in and out allows you to connect cameras and recorders to other equipment.

ANR

Avoid losing recordings with AutomaticNetwork R eplenishment.
If there are network problems, the camera stores the recordings on an SD- card - and then sends them to the recorder when the connection is stable again.
