Essex Police bought two number recognition plate cameras for £1 each after a controversial scheme was abandoned in Birmingham.
The force will use the cameras for operations during the Olympics to police events such as the mountain biking at Hadleigh.
The Metropolitan Police also bought 22 cameras while Strathclyde bought nine after Project Champion which saw 218 hundreds cameras set up in largely Muslim areas in Birmingham was scrapped last year.
The £3m counter terrorism project aimed to track movements of suspects and would have logged vehicle details but provoked an outcry from local communities over the lack of consultation.
