Product Description

Ⅰ. Product Presentation

 The portable drone detection device utilizes advanced spectrum sensing and ultra-wideband technology to accurately detect and identify various drones—including quadcopters, fixed-wing, DIY, and FPV models—even in complex electromagnetic environments. With a low false alarm rate, it provides clear audio, visual, and vibration alerts upon detection.


Ⅱ.  Product Service

1. Visit the factory and conduct on-site testing before purchasing

2. The product can be returned or replaced within 30 days if damaged under non‑human causes.

3. Multi channel after-sales service support: We offer a variety of service options, including telephone support, video conferencing, and on-site technical support (when eligible).

4. Our products have obtained CE, FCC and REACH certifications and comply with international standards.

5. We offer various modes of cargo transportation, including sea freight, land transport, multimodal transport, as well as express/parcel services via carriers such as DHL, FedEx, or postal networks. You may also appoint your preferred freight forwarder for shipment arrangements.
