(WKYC) -- By now a portable speed camera is something somewhat familiar in our area.
It's this type of camera a Maryland man says is inaccurate -- and he can prove it.
Will Foreman knew something was wrong -- either his employees all had lead feet, or the speed cameras that racked up 60 tickets for his company were flawed.
Foreman did an investigation of his own.
He took the pictures snapped by the portable speed cameras -- two of them taken 3.3 seconds apart.
With simple high school math and a few measurements, Foreman proved in court this truck wasn't going 76 mph.
Foreman claims the way the cameras are mounted makes them susceptible to factors like strong winds.
He won his speeding ticket cases in court with his math.
When he saw our story, that these cameras were being placed around Northeast Ohio, he contacted us.
We talked to the mayor of Newburgh Heights, Trevor Elkins, who just put these cameras in place.
He says he never doubted the accuracy of Optotraffic's cameras, and his officers road test the cameras on a regular basis.
Optotraffic has issued the following statement:
The "theory" regarding inaccurate speed camera readings in this report is simply false and has been thoroughly rejected by Maryland courts. The fact is laser sensors operating at 10,000 measurements per second calculate the speed of the vehicle. If the sensors detect a violation, 2 photos are taken as the vehicle continues moving down the road for the sole purpose of identifying the vehicle so that police can issue a notice of liability. Newburgh Heights Mayor Trevor Elkins sums it up best, "Optotraffic has been extremely professional in every facet of this process. I have no fear regarding the accuracy of the portable cameras utilized by the Village."
