Description

4MP ANPR camera designed for automatic license plate recognition and direct access control. Thanks to its built-in relay output and Wiegand support, it can independently control the opening of gates and barriers for vehicles on the White List. Not just plates: it integrates a suite of SMART video analytics (intrusion, line crossing, face capture) and DarkFighter technology for perfect night vision up to 60 meters.

This camera represents the state of the art in specialized video surveillance. It is not just a simple security camera, but an advanced license plate reading (ANPR) system designed to identify and log passing vehicles with surgical precision. Thanks to its 4MP (2688×1520) resolution, every detail is captured with crystal clarity, making it perfect for company entrances, private car parks or road monitoring.

In addition to its outstanding vehicle recognition capabilities, it is equipped with an advanced Smart Video Analytics engine. This turns the camera into an active prevention system, able to detect and flag intrusions or anomalous behaviour in real time, well beyond simple gate monitoring. Paired with a DVR/NVR (the product code ANK8MDG81BN is recommended) featuring smart search functions (IntelSense), it allows quick searches without accessing the camera’s panel.

DarkFighter Technology and Advanced Night Vision

Reading a license plate is a technological challenge, especially at night or in the presence of glaring headlights. The I81HX overcomes these obstacles thanks to powered-by-DarkFighter technology, which delivers sharp colour images even in extremely low light conditions. The 120 dB WDR system compensates for strong lighting contrasts, ensuring the plate is always readable, both in direct sunlight and in total darkness.

Motorized Lens and Smart Analytics

Installation is simplified by the motorized varifocal lens, which lets you adjust zoom and focus remotely to perfectly frame the transit lane. In addition to license plate recognition, the camera can classify vehicles, detecting direction, colour and type, providing valuable data for traffic management and security.

Durability and Professional Integration

Built to last, the camera features a metal housing rated IP67 (weatherproof) and IK10 (vandal-resistant). It also supports the Wiegand protocol for smooth integration with existing access control systems, allowing, for example, the automatic opening of a gate when an authorized license plate (White List) is recognized.


Beyond the Plate: Smart Video Analytics and Proactive Security

It integrates Deep Learning algorithms that let it critically analyze the scene. Thanks to its advanced detection functions, you can protect sensitive areas and receive targeted alerts only when something genuinely relevant happens:

  • Perimeter Protection (Line Crossing & Intrusion): Define virtual lines or intrusion areas. The camera will send an immediate alert if a person or vehicle crosses an unauthorized boundary or stays too long in a restricted area.
  • Flow Monitoring (Region Entrance & Exiting): Receive precise notifications whenever an object enters or leaves a specific area (for example a warehouse or a restricted gate), making it easier to control logistics flows.
  • Video Anomaly Detection (Scene Change & Defocus): The camera protects itself. If someone tries to cover it, move it or tamper with the focus to make the images unreadable, the system immediately detects “Scene Change” or “Defocus” and sends an alert.
  • Audio Analysis (Audio Exception Detection): Thanks to the audio input, it can detect abnormal or sudden sounds, adding an acoustic layer of security to the visual one.

Autonomous Gate Management and Integrated Access Control

The camera doesn’t just watch, it acts. Thanks to its onboard intelligence, the camera can fully manage access to a restricted area on its own, without the need for a PC to be always on

  • Direct Automation (Relay Output): The camera has a built-in relay output that can be connected directly to the control unit of an automatic gate, a barrier or a bollard. By creating a “White List” (list of authorized vehicles) directly in the camera’s interface, the gate will open instantly when an approved license plate is recognized.
  • Wiegand Integration: For facilities that already have a centralized access control system, the I81HX offers a Wiegand interface (26-bit and 34-bit). This lets the camera “talk” to existing control units as if it were an ordinary badge reader, but with the convenience of vehicle recognition.
  • Statistics and Counting: In addition to access control, the system can generate precise statistics on the number of passing vehicles, simplifying flow management in public or company car parks.

Advanced Search and AI Power When Paired with an NVR


Although the camera can work on its own, pairing it with an ANNKE NVR with AI functions takes the system to the next level:

  • Historical Database: You can archive thousands of transits with associated photos and metadata.
  • Plate Search: Through the NVR interface, you can perform quick searches by entering the license plate number (even partial), instantly displaying every time that vehicle passed in front of the camera.
  • Forensic Analysis: By cross-referencing ANPR data with advanced search functions, you can reconstruct the movements of a suspect vehicle in seconds, making your gate’s security impenetrable and easy to review.

Total Control With a Click: Intuitive Interface

Configuring the camera is made easy by a clean, straightforward web interface. You don’t need to be a systems expert to set up the security of your gate, because the control panel lets you turn the smart functions on or off based on your actual needs at any given time. As shown in the device’s interface, you’ll be able to independently manage

  • License Plate Recognition (Road Traffic): For monitoring and automatic vehicle access.
  • S.M.A.R.T. Events: To enable advanced video analytics logic (intrusion, line crossing, etc.).
  • Face Capture & People Counting: To turn the camera into a tool for statistical analysis and human perimeter security.

Instant Alerts Always at Hand


Notifications reach you instantly by e-mail or through the intuitive app, ensuring you’re always informed and ready to act, wherever you are.
You can monitor sensitive areas in real time, check events through recordings, or step in promptly, all directly from your mobile device.
This advanced system gives you total control and constant protection, for uncompromising peace of mind.
