AV doorbell cameras can connect through Wi-Fi, existing doorbell wiring, or Power over Ethernet (PoE), depending on the installation and camera design. Through mobile apps, smart home platforms, network video recorders, and IP-based AV systems, they can provide live video, two-way audio, visitor notifications, and event-based control of devices such as door locks or lighting.

Wi-Fi AV doorbell cameras connect to the network wirelessly and typically use existing doorbell wiring or another supported power source, which can simplify placement where network cabling is limited. Wired models use dedicated doorbell wiring for power, while Power over Ethernet (PoE) models use one Ethernet cable for both power and network communication, supporting a streamlined installation on a PoE-enabled network.

When selecting AV doorbell cameras, compare video resolution, low-light or night vision performance, HDR or WDR, two-way audio quality, and field of view, including vertical, horizontal, or ultra-wide coverage. For alerts, review whether the camera supports motion sensing, person detection, vehicle detection, package detection, or event descriptions, and consider how those options fit the entryway and notification needs.

Plan for a suitable power and network connection, such as existing doorbell wiring for devices that accept 12–30 VAC, Wi-Fi coverage, or Power over Ethernet (PoE) cabling for networked models. For outdoor deployment, select an appropriate wall or flush-mount location, account for the camera’s viewing angle and entryway lighting, and use weather protection such as an IP55-rated device where specified.
