In 2000, we’re first doorbell manufacturer in China to integrate wireless code IC, music IC and peripheral circuits into the same module, greatly simplifying the process and improving the quality.
In 2002, we launched wireless doorbell with 100 meters operating range under the most strictest EMC law in the world-TELEC(For Japan). The transmission power level required by TELEC is 1/40 of EU CE standard.
In 2006, we developed and launched circuit for SMT components, significantly
reducing product size and improving quality.
In 2012, we independently developed the first kinetic doorbell.
In 2018, we developed and launched the first kinetic Plug-Through doorbell.
Technical Strenghs:
Focused on the research and development of wireless technology for 30 years, from super regeneration to ASK, and then to FSK, with distances ranging from 100 meters to 500 meters.
1. Patented kinetic transmitter technology
We have developed more than ten different patented kinetic transmitters, with different power generation and pressing force, which can be used in different scenarios with different products to meet diverse market needs
2. Kinetic transmitter with DC doorbell
The world's first patented invention technology, receiver battery lifetime last over 1 year. Currently, we are the only manufacturer in the industry that has the technology.
3. Compatible AC&DC doorbell receivers
Traditionally, the signal baud rates of battery transmitters and kinetic transmitters are different, and the operating modes of the receivers they are paired with are also different, making them incompatible. After 2 years of research and development, we have successfully developed a self adaptive doorbell receiver that is compatible with both battery transmitters and self generating transmitters.
4. Ultra low power battery consumption
Using several AA batteries with a lifetime of over 2 years, it is at the leading role of the industry.
5. Fix the signal “Puzzle”
Innovation is being made to address the technical bottleneck of kinetic transmitter. Traditional kinetic transmitter generate very little amount of electricity, result to very short effective signals after conversion. Once the signal is partially interfered, it cannot be effectively caught. We have created our own software splicing technology to fix the interfered signals into a complete and effective signal like Puzzle, greatly improving the stability of signal transmission.
6. Open Air simulation testing equipment
We developed unique test box and used to test receiver sensitivity, making it possible to quickly simulate and test open air distance for mass-produced products, saving production costs and reducing delivery leadtime (previously all manual testing, now all instruments are used to maintain product accuracy and consistency).
7. Mini series receiver
The signal reception is greatly affected by the space of receiver. The smaller the doorbell is, the more difficult the ensure the reception of RF signals. With decades of development experience, our company has successfully adjusting component parameters, antenna and other circuit configurations, and achieved a communication distance of 200+ meters on Opan Air. We have developed the smallest receiver in this industry.
