Many of our devices are designed to utilize Power-over-Ethernet (PoE), allowing them to draw power from a compatible Ethernet switch. This feature can significantly reduce cable clutter and streamline the installation process. However, if your switch does not support PoE or if you plan to connect the device using WiFi, a separate power supply will be required. For your convenience, power supplies can be easily added to your purchase from the Add-ons section on the product page. This ensures that your device is equipped with the necessary power source for its optimal operation, aligning with your specific setup requirements.
