Weatherproof wired doorbells connect to an existing doorbell transformer and chime, while Wi-Fi models use a wireless network and can be well suited to retrofit installations. Power over Ethernet (PoE) doorbells use one Ethernet cable for power and network communication, which can simplify cabling for new construction or structured low-voltage installations.

Plan around the doorbell’s connection type: wired models may require a 16/24VAC, 10–40VA transformer and chime, PoE models use one Ethernet cable for power and network communication, and Wi-Fi models require a suitable power source plus reliable wireless coverage. Verify the existing transformer, chime, Ethernet run, or Wi-Fi signal before installation, and confirm that the selected doorbell’s outdoor protection rating suits the installation location.

For monitoring outdoor entryways, look for high-resolution video with a wide or dual-lens field of view, low-light or infrared night vision, and two-way audio for viewing visitors and communicating with them day or night. Motion detection with person, vehicle, package, animal, or sound alerts, adjustable zones and sensitivity controls, and weather-resistant construction can help focus notifications on relevant activity.

Weatherproof doorbells can connect to security and smart home platforms through Wi-Fi or Power over Ethernet (PoE), allowing users to view live video, receive activity alerts, and communicate with visitors through an app or touchscreen. When supported by the system, doorbell events can also trigger actions such as recording video, unlocking a door, disarming an alarm, opening a garage door, or turning on lights.
