Self-powered technology

When press the doorbell button, your kinetic energy will be transfer into electrical energy, which can be used to send a radio signal. Therefore,the energy is harvested and battery is not needed. We have applied patents for this revolutionary technology.

Strong signal

If no barrier exists, the transmitting distance will be up to 100 meters. The factual indoor transmitting distance is 30-50 meters, which can fit the common area of home.
With the help of relay, it can be transmitted longer.

Low power consumption Wide voltage

The receiver needs AC power supply. For advanced on-off step-down power supply is applied, the power consumption is low to 2w. The suitable voltage range is 86-365 v, which can fit the power supply standard of most countries.

Relay function

The traditional receiver of the doorbell can receive the signal only. Our doorbell receiver can forward the signal to each other at the same time when it receives the signal, so that enlarge the receiving range.

Unique coding

Our doorbell applies "16-bit lead code + 32- bit ID code + 24-bit content code + 8-bit CRC". Such complex design is used to ensure every product has one unique code, which can lower false ring probability to 1/1,000,000,000,000.

Q1.If no wire and battery-free,how can the doorbell work?

A:When you press the key on the transmitter, the self-powered coils of the inner module will be moved. It can transfer the kinetic energy into electrical energy, which can be used for driving the low-power consumption circuit to send radio signal.

Q2.Will the transmitter trigger other neighbors Linbell or 433.92MHZ facility near by?

A:Each transmitter have a 32bit ID,and this ID is unique in the world,so it won't trigger other neighbors Linbell near by,let alone other brand's device.

Q1. Can I have a sample order for this wireless doorbell?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

Q2. What about the lead time?

A:Sample can be sent out within 3 working days, mass production time needs 1-2 weeks.If OEM,the delivery time is 30 days after customed sample is confirmed.

Q3. Do you have any MOQ limit for doorbell order?

A: Low MOQ, 1pc for sample checking is available.If OEM,MOQ is 1000 sets.

Q4. How do you ship the goods and how long does it take to arrive?

A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 5-7days to arrive. Airline and sea shipping also optional.

Q5. How to proceed an order for doorbell?

A: Firstly let us know your requirements or application.
Secondly We quote according to your requirements or our suggestions.
Thirdly customer confirms the samples and places deposit for formal order.
Fourthly We arrange the production.

Q6. Is it OK to print my logo on doorbell product?

A: Yes. Please inform us formally and confirm the design firstly based on our sample.
