The JetCam Fox-i Intelligent ALPR camera is intended for use in applications where it is required to process the ALPR images at the time of capture. With other cameras it requires streaming all the video back to a central control room or using a sturdy roadside processor such as the Blackbird or Silverbird sited in a waterproof roadside cabinet. Whilst the latter solution is extremely powerful, it can be expensive to install which can work out to be prohibitive for various applications.
Until now, ALPR providers have fully depended on powerful Intel™ based PCs with bus-based video frame grabbers to endeavor to accomplish impressive recognition rates from fast flowing traffic. Leading engines such as the Jet™ ALPR Engine achieve outstanding results by accumulating numerous plate reads as a vehicle passes.
When confronted with the trials of producing compact intelligent cameras the majority of manufacturers have decided to use small, low power digital signal processors (or comparable) to process the images on board.
These specialized processors suffer in two ways:
They just cannot supply the processing power needed for the most accurate multi-read ALPR engines.
Proprietary hardware is not easy to modify or add customized on-board features.
The JetCam Fox-i has been developed over a number of years to tackle these issues and is based upon a new generation 1GHz processor running Embedded Windows™ with 512MB of DDR2 SDRAM and up to 64GB of flash memory.
The fundamental ALPR camera has a High Definition resolution of 1280 x 960 for use on wide or dual lanes, Toll Plazas or site entrances of over 5m in width. An optional day / night color overview camera is offered to obtain not only the plate details but also a color contextual image of the event.
The resulting system uses nominal power and is quick enough to process at full frame rate as each vehicle passes the camera at a fast pace, resulting in what we consider to have the greatest precision across all intelligent ANPR camera on the market.
The Fox-i is completely NAAS and BOF-2 compliant.
Once the plate has been read, the Fox-i transfers the plate text, with optional color overview images using TCP/IP via a network connection – or through the on-board 3G modem.
The Fox-i camera can buffer up to 64 GBytes of event data within the camera to transmit at a later date. This allows over 128 million plates (data only) – or over 1 million plates with full color overviews can be accumulated in an encrypted format at the camera head if necessary. This buffering prevails any collapse in communication or network bandwidth issues.
Simple plate information is transmitted along with the camera ID and GPS location from the on-board receiver to an ALPR Server. When a hit takes place at the server, a signal can automatically be sent to the Fox-i which instantly returns the correct overview imagery.
