Radar Vehicle Detector
GoRad® radar vehicle detector is widely used in various parking applications such as anti-barrier crash systems, vacant space counting, and intelligent lane safety monitoring. Compared to traditional vehicle detection methods using inductive loops, radar technology offers groundbreaking advantages—it enables quick installation without ground excavation and overcomes issues such as lane closure during construction, complex wiring, and high maintenance difficulties.
This non-invasive radar vehicle sensor allows flexible adjustment of detection range, sensing width, and driving direction. It can efficiently detect various vehicle types and pedestrians, making it especially suitable for high-chassis vehicles and large transport equipment that traditional loop detectors struggle to sense. The intuitive LED status display provides real-time equipment status for improved maintenance efficiency.
Additionally, its nut-fastening design enables quick installation and removal, allowing easy replacement and repair by on-site personnel—greatly reducing labor and time costs. As a key device for building high-performance, low-maintenance, and environmentally sustainable smart parking lane control systems, the radar detector not only enhances detection accuracy but also significantly improves the overall operational efficiency of the parking facility.
Overview
Traditional vehicle and pedestrian detection at gate entrances typically rely on inductive loops and infrared sensors. However, both solutions present several serious challenges in real-world operations, summarized as follows:
Issues with Inductive Loop Detectors
- High cost of cutting and repairing pavement during installation.
- High maintenance cost due to the need to replace the loop every two years.
- Faulty equipment is not immediately detectable.
- Limited detection—only passenger cars are sensed; high-chassis vehicles, motorcycles, bicycles, and pedestrians are undetectable.
- Unsuitable for areas above high-voltage cables, fiber optics, water, or gas pipelines.
Issues with Infrared Sensors
- Limited installation locations; requires paired setup on both sides of the entrance.
- Poor adaptability and high false alarm rates; prone to interference from light sources, falling leaves, etc.
GoRad-79G as the Complete Solution
The GoRad-79G radar vehicle detector effectively addresses the pain points of loop and infrared systems. Utilizing the same radar technology used in adaptive cruise control systems, it accurately detects vehicle types (cars, trucks, motorcycles, bicycles) and pedestrians, protecting them from barrier collisions. In addition to precise detection, it offers IP66-rated waterproofing, resistance to extreme climates, easy installation, and simple maintenance—delivering outstanding all-around performance.
Key Features
Compared to traditional vehicle counting systems based on inductive loop detectors, radar-based vehicle detection offers many impressive advantages:
LED indicators show radar working status for intuitive monitoring without opening the housing.
Utilizes 79GHz MMIC radar sensing—same as in adaptive cruise control—with IP66 waterproof housing. Immune to electromagnetic interference, lighting, dust, rain, and snow.
Standalone installation without environmental constraints—no cutting or burying of loops, making deployment and maintenance faster and preserving lane aesthetics.
Customizable detection range: lane width (±1.5 m), distance (1–6 m), and height (2.25 m)—suitable for various lane types and vehicle sizes.
Detection modes are configurable via software for different parking lot requirements.
Supports vehicle/pedestrian distinction—accurate detection of cars, trucks, motorcycles, bicycles, and pedestrians to prevent barrier collisions.
Capable of detecting driving direction.
Radar sensors offer a lifespan of over 5 years—far longer than traditional loop detectors.
