Phased Array Bird Deterrent: Dual Acoustic & Pulse Defense
Traditional bird control methods—such as spikes, basic ultrasonic devices, and reflective mirrors—often fail quickly. Birds develop a tolerance to them, and the constant, omnidirectional noise from standard speakers frequently leads to complaints in nearby residential areas. To solve these persistent issues, the DH-E510 introduces advanced phased array bird deterrent technology. By combining high-energy directional acoustics with a safe high-voltage micro-pulse, it creates a dual-sensory defense system that delivers long-lasting, humane protection without noise pollution.
Dual-Sensory Deterrence: Sound and Touch The core innovation of this phased array bird deterrent is its "acoustic-tactile" approach, which creates a deep "fear memory" in birds that prevents them from returning. First, the system utilizes a high-energy directional acoustic wave. Unlike traditional speakers that broadcast sound in all directions, the phased array focuses acoustic energy tightly forward. At a distance of one meter, the sound pressure level reaches an impressive ≥130dB, with an effective deterrence range of 10 to 80 meters. Crucially, the sound decays rapidly behind and to the sides of the device, ensuring zero noise disturbance to surrounding neighborhoods. If birds venture closer, the system activates its second layer of defense: a high-voltage micro-pulse. The voltage is adaptively regulated between 5kV and 10kV, but the energy is strictly limited to <0.1J. This safely adheres to international animal protection standards, delivering a strong tactile warning without causing any physical harm to the birds.
AI Dual-Sensor Detection To prevent false alarms and conserve energy, the DH-E510 features AI dual-sensor perception. It integrates millimeter-wave radar with a PIR (Passive Infrared) thermal release sensor. The deterrence system only activates when both a moving object and a heat source are detected simultaneously. This intelligent filtering effectively ignores wind-blown leaves, rain, and debris, significantly reducing power consumption and extending battery life—especially during cloudy or rainy days.
Rugged and Autonomous Operation Built for harsh outdoor environments, the device features an IP66 weatherproof rating and operates reliably in temperatures ranging from -20°C to +85°C. It is powered by a solar panel and a lithium battery, ensuring continuous, autonomous operation even in remote locations. Data and status updates are transmitted via a 4G communication interface, allowing operators to monitor the system remotely.
Versatile Applications This phased array bird deterrent is highly adaptable across multiple industries:
Power Grids: Protects transmission towers, substations, and distribution transformers from bird nests and corrosive droppings that cause flashovers.
Aviation & Airports: Secures runways, aprons, and radar stations to prevent bird strikes.
Transportation Hubs: Safeguards high-speed rail catenary pillars and highway noise barriers.
Large Industrial & Commercial Facilities: Protects warehouse roofs, solar farms, and port terminal cranes.
By merging directional acoustics with safe tactile pulses, the DH-E510 ensures that birds are effectively repelled without harm, offering a sustainable, eco-friendly, and highly efficient solution for critical infrastructure.
