Malaysia's Automated Enforcement System explained

The video tutorial explains the AES, a system of cameras designed to enhance road safety by monitoring roads in all weather conditions. The cameras, equipped with radar, can cover all lanes for 80 meters and accurately identify offending vehicles. The 11-megapixel cameras take six sequential shots, which are sent to the JPJ for verification before issuing a summons. The AES is installed at accident-prone areas to reduce accidents by half.
