In below articles, we would like to provide our audience basic understanding on the parameters that one manufacturer have to balance during the design process of a photo-radar system so you can understand it better and make certain comparison of one photo-radar traffic system over others.
Let get started!

All the features of any device can be split for two different categories. They are formal features (FF) and consumer features (CF). FF and CF are not always unified. Sometime FF is very important for the customers but not every time. Any producer try to highlight their best FF, however CF are the most important for customers.
A non-user oriented solution will talk about the camera resolution, computing power, operating system or the interface. While a user-oriented will focus on speed measurement accuracy, ANPR recognition probability, recognition error probability, power consumption and data transmission.
Since now time it is not benchmarking of digital photo cameras, speed enforcement cameras are not about megapixel. They are designed for performing distinctive tasks.
The fewer megapixels the cameras are, the more contrast and high sensitivity it has in low lighting condition. The more megapixels the cameras are, the more detail pictures it can give but less contrast in low lighting condition.
This parameter have to be balanced - the size of pictures have to be sufficient for recognizing the symbols of license plate, and at the same time pictures have to utilize as less operating memory as possible - to be processed quickly and to utilize less space when stored.
In common design approach, ultra-high resolution cameras of 10-20MP are used for good license plate recognition probability (95%). The result is large size image files, powerful industrial computer, high capacity storage, high band-width internal bus, powerful cooling system and high power consumption.
In advanced approach, thank to advanced license plate recognition technique based on neural network, SIMICON only use the sufficient resolution of 4MP camera to get 98% probability of license plate capturing. The image size reduced to 100kb compared to 0.6-4Mb of common approach. It also lower the power consumption from 500-1000Wat to 10 times, making it suitable to various source of power supply (solar panel).
All-in-one solutions: speed measurement, red-light infringement, license plate recognition and detecting the violations, statistic collection and analysis are performed on the products itself without additional cameras, external or remote computing devices.
The weight of SIMICON photo-radar system can be light and size can be compact to easily handle, install and mobile.
Small size images allow multiple ways and cut down the cost of transmission infrastructure, cable and network. Besides conventional Fiber optic - 10Gbit/sec, Ethernet - 1Gbit/sec, we have WiFi- 54Mbit/sec, 4G(LTE)-30Mbit/sec, 3G (UMTS, HSPA) - 0.3.02Mbit/sec.
To be an end-user, think about the productivity of your system, the bandwidth, storage, power consumption cost and probably cost of maintenance, transportation .etc, probably it will help you to determine which products will serve you the best.
If you have any question or interest on speed or traffic enforcement system, please kindly feel free to contact us at sales@marc-corp.com. We are actively seeking for our partners in South East Asia for a safer and better traffic environment.
