A precise COUNTER for a parking space is necessary for these days. The conventional loop coil cannot detect the edge of a vehicle accurately. V-COUNTER uses the specially designed CARDET-301H that has a capability to detect the edge of an any vehicle precisely, and the parallel processing algorithm in a V-COUNTER executes the accurate counting function even under various situations such as a backward driving, bump-to-bump, in-and-out. etc. It has a elaborate road database.
