bitsensing 4D Imaging Radar & TIMOS Traffic Sensor

bitsensing Inc. is a radar company headquartered in Seongnam, Gyeonggi-do, South Korea, led by founder and CEO Dr. Jae-Eun Lee. It covers the full path from radar design to mass production and applies automotive-grade radar to vehicles, city traffic and healthcare, where cameras struggle with darkness, weather or privacy.

The automotive line includes 4D imaging radar with range above 300 m, corner radar and in-cabin radar, plus an ADAS Kit that retrofits driver warnings to existing commercial vehicles. TIMOS is an all-in-one traffic sensor with built-in AI that covers 12 lanes, classifies vehicles and flags wrong-way driving or speeding, and can be fused with video. A health radar monitors sleep quality, apnea events and limb movement without contact. Customers include carmakers, road operators, city governments and care providers.

• 4D imaging radar: high-resolution front radar with range above 300 m for automated driving.
• Corner and in-cabin radar: surround detection and occupant sensing for vehicles.
• ADAS Kit: retrofit driver warning system for existing commercial vehicles, launched in 2026.
• TIMOS traffic sensor: AI radar covering 12 lanes with vehicle classification and incident detection.
• Radar-vision fusion: combines TIMOS radar with cameras for expressway and intersection monitoring.
• Health radar: contactless monitoring of sleep quality, apnea events and limb movements.

Expressway operators and traffic authorities in Vietnam can deploy TIMOS for lane-level counting, speed and wrong-way detection in rain and at night. Logistics and bus companies can retrofit the ADAS Kit to existing fleets. Nursing homes and hospitals can pilot sleep radar for contactless monitoring of elderly patients.

Radar works in rain, fog, glare and darkness and does not capture identifiable images, which suits public roads and bedrooms. One TIMOS unit covers up to 12 lanes with on-board AI, reducing the number of roadside devices and the need for central processing. The ADAS Kit brings driver warnings to existing truck and bus fleets without replacing vehicles. Contactless sleep radar lets care providers monitor residents without wearables.

Stricter vehicle safety rules in Europe and Asia are pushing ADAS into more vehicles, including commercial fleets. Cities are investing in intelligent transport systems that need sensors working in all weather, and ageing populations raise demand for non-intrusive remote care. Southeast Asian countries, including Vietnam, are expanding expressways and smart traffic centres where radar-based monitoring can complement cameras.
