Building a Jet ANPR System
A Jet ANPR system is built around a standard Windows PC running Jet Software.
Jet will run on Windows 2000,NT or XP - but it is the peripheral cards that usually force the choice of operating system.
Images are captured using standard low-cost frame grabbers - although our own range of high performance grabbers (JG Grabbers) will give a faster throughput for multiple lane systems.
Connected to these grabbers are video cameras. Specialised ANPR cameras are used to capture number plates - and more than one camera can be connected to each "Lane".
This is useful in situations where traffic lanes are wide (more than 3m) - or when vehicles can approach a barrier from more than one angle - making one camera useless in 50% of the cases.
In addition, colour overview cameras can be added to capture an image of the driver - or a general picture of the car showing the make and colour etc. This can be very useful in identifying drivers.
The system can control internal or external LED signs - these are controlled using the PC's serial port.
If the system is to control traffic lights and/or car park barriers then a digital I/O card is required.
CitySync supply these. (See Products - Digital I/O Cards).
... and that is all you need!

Now, putting it together is slightly more difficult - and CitySync will always help you.
Points to consider when specifying the system:
