Amsterdam has started the fight against noisy motorcycles and cars. On Friday, the city placed electric road signs in two places to warn road users if their vehicles are too loud. The warnings will eventually be replaced by “noise cameras,” which, like speed cameras, automatically send a fine to the offending driver, Parool reports.
This can be done without constantly recording or transmitting what the microphone perceives. It can simply start recording sound and picture when a noise is detected that is loud enough / matches the pattern we’re looking for. This can be done just on the device. No big brother tech needed.
