Ezcam Speed Camera Detector
- (Speed cameras) A traffic enforcement camera (also road safety camera, road rule camera, photo radar, speed camera, Gatso) is a system, including a camera which may be mounted beside on over a highway or installed in an enforcement vehicle to detect traffic regulation violations, including
- Speed limit enforcement is the action taken by appropriately empowered authorities to check that road vehicles are complying with the speed limit in force on roads and highways.
- (Speed Cameras) This layer includes Traffic Calming Speed Camera locations within the Royal Borough of Windsor and Maidenhead and Surrounding Area.
- A device or instrument designed to detect the presence of a particular object or substance and to emit a signal in response
- any device that receives a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it in a distinctive manner
- rectifier that extracts modulation from a radio carrier wave
- electronic equipment that detects the presence of radio signals or radioactivity
Overview of the timings from the detector. To simulate the ambient light one IR laser is set in continue mode. The signal level on the detector for this simulated light was about 65 ( right side diagram) the ADC has a range of 2.56V, so 65 means .65V or 650 mV. The left side of the diagram show where the second but now pulsed IR laser come in action. This pulsed light goes now to level 105 or 400 mV above the simulated ambient.
On the diagram you see also how long its take to transfert a data string via the SPI bus. This time is 1.83 usec to transfert one 8 bit ADC value. The total cycle time for 2 measurements is 65.35 usec. On the diagram you see also where the laser drive is on and off. The AVR controller runs on the internal clock of 8 MHz.
