A PoE (Power over Ethernet) adapter that provides 24W (watts) is a device that enables both data transmission and power supply over an Ethernet cable. PoE adapters are typically used to power devices such as IP cameras, Wi-Fi access points, VoIP phones, and other network devices without the need for an additional power source.

The 24W power rating indicates the maximum power output provided by the adapter. This level of power is generally suitable for low-power devices like smaller network cameras or low-power access points.

Key aspects of a 24W PoE adapter:

1. Power Delivery: It provides up to 24 watts of power over an Ethernet connection.
2. Standard: It may support IEEE 802.3af (the most common PoE standard), which supplies up to 15.4W of power, or IEEE 802.3at (PoE+), which supports up to 25.5W, but 24W is on the lower end of that spectrum.
3. Ethernet Connection: The adapter will provide both network connectivity and power through the same Ethernet cable.
4. Devices Powered: Ideal for small devices like IP cameras, entry-level Wi-Fi access points, and phones.
5. Installation: Usually used in small-scale installations, such as home networks, offices, or small businesses.
