Rather than focusing on consumer-facing retail branding, the company operates primarily as an OEM (Original Equipment Manufacturer) and supplier. They design the internal chip architectures, firmware, and USB dongle hardware that are then rebranded and distributed by various global tech retailers. Core Technologies and Products
Modern HaisenKeji sensors have moved beyond physical "DIP switches" to Bluetooth-app control No Ladders Required:
HaisenKeji specializes in 5.8GHz and 10.525G microwave motion sensors Precision Sensing:
The keyword encapsulates the dual nature of modern electronics manufacturing. On one hand, it represents the niche consumer hardware engineering that democratizes high-fidelity wireless audio for everyday desktop users. On the other, it represents the vital, invisible B2B industrial infrastructure that keeps global transportation and technology networks operating safely behind the scenes.
Key Milestone: In 2020, Haisenkeji secured a Series B funding round led by a consortium of green energy VCs, valuing the company at approximately $450 million. This capital injection allowed them to expand into the renewable sector—specifically smart grid management for solar farms.
