The criteria you can use to compare the different wireless bells include

  • Reach
  • Applicability
  • Robustness
  • Power consumption
  • Installation

In the following paragraphs we will explain what is important for each of the criteria.


Before you buy a wireless bell, you should know what range you will need. In the basic version the bell has a range of 100 to 500 meters. However, it is recommended that you buy a wireless bell with a greater range than you actually need.

This refers to the distance from the bell to the receiver in your home. This is because the range can already be reduced if there are obstacles in the transmission path. This can be a concrete wall, but even a small bush can disturb the range of the bell.

A radio extension can help to achieve a greater range of the radio bell.

So when buying, keep in mind to buy a bell with a higher range.


Make the choice of your radio bell depending on what you need it for. You can use it as a doorbell for your home. For seniors, or people who are hearing impaired, these bells can also be used well.

On the other hand, it is possible that you attach them for an office building, factory, hotel or for use in a nursing home.

Did you know that you can use the radio bell to activate lights?
It is also possible to set a wireless bell to answer phone calls. It can also be used to activate sirens and open gates.


When buying the radio bell, make sure that the manufacturer has attached great importance to robustness during production. Since the bell is installed outdoors, it must be weatherproof. This means it should be able to withstand various weather conditions and be able to withstand degrees between minus 20 degrees Celsius and 60 degrees plus.

Note the casing of the radio bell. The housing should be on robust stainless steel or plastic material. Thus the radio bell can remain functional for a long time.

Power consumption

The power consumption of the radio bell is moderate, with some exceptions. There are battery operated wireless bells where you have to connect the receiver to the mains. Read the product description before you buy, or get advice in the shop and pay attention to the power consumption of the radio bell, as it varies from manufacturer to manufacturer.

By connecting to a power supply system, a continuous power supply is provided and the receiver can be attached flexibly. The transmitter only requires power when actuated. Before buying, let yourself think about which type you prefer. A battery-operated bell, or a radio bell, with the receiver connected to the power supply.

The most important thing is how much power the devices consume in standby mode. It is worth doing a little research before buying. Most devices consume less than 1 watt in standby mode, which is almost nothing for one year. (Source: simply


A big advantage of a radio bell is that it is easy to attach. When buying it, you have to pay more attention to what materials you buy for installation. The radio bell can be fixed with double-sided adhesive tape, glue or screws. Through our research, we can recommend that you buy screws rather than tape, because they will last better in the long run. Adhesive or tape will become loose over time.

The good thing about this simple installation is that you can easily remove the bell at any time. Depending on the model, you only have to put a battery in the receiver or in the radio bell, or connect it to a power supply.
