DNET Co., Ltd. develops and manufactures microwave radar sensors for security and intrusion detection. The company is built on its own microwave motion sensor module — the core component of radar sensing — and is the only manufacturer of this module in Korea. On that foundation DNET builds complete detection systems, from residential detectors through to installations protecting military bases, ports, LNG terminals and other critical infrastructure.
The product line covers perimeter line detectors (DND-30/60/90), dual microwave-and-infrared barriers (DND-100B), and the AI-based wide-area security radar DND-T Series, which detects and tracks up to 32 targets at ranges of up to 500 metres. All products apply DNET's proprietary object pattern recognition signal processing, which suppresses the false alarms caused by birds, small animals and moving vegetation that limit conventional sensors.
DNET also combines technologies across its lines to develop bespoke sensors for specific customer requirements. A substantial share of its output is exported, with Europe and North America among its principal markets.

DND-T Series — AI-Based Wide-Area Security Radar
An FMCW security radar operating at 24–24.25 GHz, available in four detection ranges: 100 m, 150 m, 300 m and 500 m for a person, and up to 600 m for a vehicle. A single unit covers a 90° horizontal field and tracks up to 32 targets simultaneously, with synchronised data output for 10, reporting range, bearing, direction and speed with ±0.75 m range accuracy and ±1° angular accuracy.
AI-driven object pattern recognition distinguishes people and vehicles from birds, small animals and moving branches, addressing the false-alarm problem that limits conventional perimeter sensors. 2D FFT signal processing with target cluster tracking maintains identification in cluttered scenes, and radar-video fusion adds 3D positional tracking with automatic camera hand-off.
The bundled software handles zone configuration, live monitoring and camera linkage. Rated IP66 and specified from −40 °C to +65 °C with an MTBF above 50,000 hours, it connects over a single PoE++ RJ45 cable, simplifying installation across airports, industrial sites and large-scale facilities.
