The JetCam Fox HD Dual GigE camera is intended for use in applications where high resolution ALPR images are needed for instance for two lanes or wide traffic lanes. In these circumstances two analog cameras can have a 'blind spot' between the lanes so three cameras would be necessary for 6m wide fields of view. Such groups of cameras are not aesthetically pleasing and installation becomes costly.
Two lanes of traffic can be observed with one Fox HD camera.
Standard analog ALPR cameras are not usuable where more vertical resolution is required such as in DSRC Tagging systems. (Dedicated Short Range Communications).
In these situations cameras are normally positioned up high (6-7m) and are required to read a vehicles plates within the normal DSRC range (7-12m). This greater vertical angle distorts plates which can only be read at high accuracy by using high resolution vertical imaging. The JetCam Fox HD camera provides this.
The JetCam Fox HD has a horizontal resolution of almost 1400 pixels able to cover 6-7m of road. The increased vertical resolution of over 1000 pixels is used by the Jet ALPR Engine which is able to capture a number of images as vehicles pass producing higher recognition accuracy. The vertical resolution maybe linearly traded off against frame rate if needed.
A new wide lane power-managed LED technology has been used to ensure that the Infra Red illumination precisely matches the wider field of view. This higher level operation allows the camera to capture plates at night against full headlights at a distance of roughly 40m.
The main feature of the JetCam Fox HD Camera is its intelligence. Communication with the camera is through a GigE digital interface that allows the camera to be managed in real time from the Jet ALPR Engine which continually checks the brightness and condition of all recognized number plates.
Jet also employs dynamic control to different settings, for instance high-quality digital gain and shutter speed, fine tuning the final image which is then transferred to the ALPR computer.
This significantly improves ALPR recognition in extremely demanding and variable lighting conditions.
