Pick a doorbell that is heat and water resistant. Choose a doorbell with varying frequencies. Ensure the range is sufficient. Decide how many receivers you would like. Pick between battery-operated or electric power.
While it seems like all doorbells should be able to withstand varying weather conditions, that's unfortunately not the case. Be sure to choose one that will last throughout the seasons and won't be damaged by fluctuating temperatures, rain, or snow. Look for a bell with packaging that specifically states it is weather-resistant or weatherproof. Because wireless bells use radio waves to transmit the signal, you should pick one that can operate on multiple frequencies. This will ensure that neither your neighbor's wireless doorbell nor their garage door opener signal your own doorbell to chime. If you find that there is interference, simply change the privacy code on the bell to adjust the frequency. The size of your home will determine the range that you'll need. A standard wireless doorbell has a range of 150 feet (46m). If the interior of your home has a distance greater than this, you'll need to choose a bell with a wider range. Interior walls can also interfere with the range of a bell, so take your room configuration into account. If you have your heart set on a certain bell, but the range is insufficient, buy an extender to increase the range so that it can be heard throughout your home. If you have a large home, you may want to place receivers in more than one location. For instance, you may want one on every level of your home, or you may wish to place an additional receiver somewhere where it may be difficult to hear the main receiver, such as the laundry room. Wireless doorbells need a power source, and you have a choice of what kind of source you prefer. If the location you'd like to put the bell and receiver are near outlets, then you can go with an electric bell. If there's not an outlet handy, you may want to choose a battery-operated doorbelljust be sure to stock up on extra batteries and change them out when needed.
