Appian Technology PLC

The Stinger Intelligent Automatic License Plate Recognition Camera has cameras, illuminator and processor all fully integrated in a single sealed unit offering ease and simplicity of installation. The Stinger is designed to process and recognise license plates and associated imagery and then transmits results using its integral communication interfaces. Communication options include GSM/GPRS or 3G and 802.11g WLAN and 100Mbps Ethernet.

The Stinger camera components are based on Appian’s high performance Cobra Camera. Users can select a range of camera and IR illumination options offering unmatched flexibility, including dual cameras and long range illumination options. A principal feature of Stinger is the use of high resolution optical zoom cameras - both for ALPR and high definition overview/contextual imaging. Zoom functionality means the Stinger system can be rapidly optimised to suit differing plate and environmental conditions at ALPR capture points. All camera settings can be controlled and adjusted remotely in real time.

The processor element takes imagery from the camera and runs the plate recognition processes. Neural network Talon ALPR software is used as standard, Stinger can support additional recognition engines. The processor is a powerful mini computer specifically developed for military image processing applications.

Featuring a 20GB hard drive and a Windows OS local hotlists can be securely stored and managed. This feature allows the Stinger to be directly connected to any web based services such as BOF2. The choice of processor and Windows OS offers great flexibility; additional electronic sensors, devices and applications can be readily integrated. These include (but are not limited to DSRC/RFID), speed and red light detection devices - all connected to and controlled by Stinger. The robust processor is designed to operate in harsh environmental conditions including extreme temperature fluctuations. The processor is capable of handling up to 4 separate video inputs, each Stinger has the capability to connect and process imagery from a ‘slave’ Cobra dual ALPR camera.

A telemetry interface can be provided as an option to control a pan and tilt head for both the Stinger and slave Cobra ALPR camera. This allows users to reconfigure cameras for different traffic conditions.

A Stinger ALPR system requires minimal installation and its discreet appearance has little impact on the environment, making it an ideal stand alone ALPR surveillance system.
