Nowadays, our lives are getting more and more comfortable, and security has become one of the more important concerns of the day. Behind the heavy security doors, sometimes you knock desperately outside, but the person inside the door may not even hear the sound, so it is necessary to install a doorbell to the homes.
Doorbells can generally be divided into the following categories, wired doorbell, active wireless doorbell and wireless doorbell without batteries. These kinds of doorbells can achieve different functions and come with different advantages and disadvantages because of the power supply.
Through these kinds of doorbells comparison, in general, wireless doorbell without batteries is more cost-effective, wired doorbell is too much trouble, ordinary wireless doorbell has high battery power consumption and short life. And self-generated wireless doorbell is simple and practical.
Self-generated wireless doorbell uses energy capture technology, through the transmitter to collect energy, each time when the user presses the doorbell, the energy will be converted into electricity in time. The signal generated by the doorbell button is sent through the wireless signal transmitter, the wireless signal receiver in the room will ring the bell after receiving signal.
How To Pick The Wireless Doorbell

1. Price
Since the self-generated doorbell add self-generating module, the cost of construction is higher than the ordinary wireless doorbell, while the control module and RF module used is also low-power type, so the overall cost will be high, that is, the price of wireless doorbell without batteries is higher than the active wireless doorbell, we should avoid greed for small bargains when choosing.
2. Transmission distance
Good wireless doorbells choose RF technology for signal transmission, theoretically they can reach 80m long-distance signal transmission, but consider that the purpose for choosing wireless doorbell is mainly used for family, meeting the following three floors of the building is basically enough.
3. Signal frequency band
Because the wireless channel resources are very limited, many doorbells on the market use the 315MHz frequency band, which is prone to interference. Maybe the neighbor next door rings the doorbell, but your bell rings, and the doorbell string code appears. In the case of false ringing or a sudden drop in the working distance, when choosing a wireless doorbell, you should choose one with multiple channels, so that it is convenient to switch and replace the signal frequency band in time.
4. Volume adjustment
Considering the hearing loss of the elderly, the volume level of the doorbell is preferably settable. The AVANTEK doorbell I bought at home can reach up to 75 decibels, so there is no need to worry about the elderly missing listening.
5. Waterproof level
The call host of the wireless doorbell is installed outdoors, and it is inevitable to wind and rain. This has a minimum requirement for the waterproof level of the product, which is at least IP47 dustproof and waterproof standards.
Considerations When Buying A Wireless Doorbell
The selection of wireless doorbells is generally relatively simple. As long as you identify the brand and don’t covet the cheap ones, you can buy a wireless doorbell that suits you. For example, the sound of the bell is very small, which requires you to pay attention to the following points when using the wireless doorbell.
- Never install it next to electrical appliances with electromagnetic waves such as TVs, induction cookers, microwave ovens, etc., because these electromagnetic waves will interfere with the doorbell signal.
- Do not install the doorbell on the iron door, because the iron door will have a magnetic field effect, which will interfere with the reception of wireless signals.
- There is a small spacer on the battery under the transmitter on some wireless doorbells. Don’t throw this away, or your doorbell may not work.
