Seongnam is installing Korea's first motorcycle noise-monitoring cameras to address late-night speeding and noise from illegally modified motorcycles.
The city said Thursday it will operate motorcycle noise cameras at two locations, one in each direction, along the Godeung Intersection–Tokkimadang Intersection section of Daewangpangyo-ro in Sujeong-gu. Installation work runs from Friday through the 21st.
The area sees frequent complaints from late-night speeding and motorcycles with illegally modified mufflers. According to the city, the area received an average of 86 noise complaints per year over the past three years, from 2023 to 2025.
The newly installed equipment features precision noise meters, 8.9-megapixel high-resolution video devices, and acoustic equipment for tracking noise sources. When a moving motorcycle generates noise above a set threshold, the system automatically recognizes and photographs the license plate while measuring and recording the noise level.
The enforcement standard is 105 decibels. That is higher than the 100 decibels of railway-side noise generated when a train passes.
Based on the collected data, Seongnam plans to analyze the operating times, frequency, and driving characteristics of high-noise motorcycles. The city will also identify illegally modified mufflers and use the findings for joint crackdowns and guidance activities with police and other relevant agencies.
However, under current law, administrative measures such as fines cannot be imposed based solely on noise camera measurements. The city plans to send notices to detected vehicles to encourage voluntary corrections.
"Through a constant monitoring system, we will respond effectively to speeding and excessive noise," a city official said. "We will minimize inconvenience to residents' daily lives."
