Motion sensors are important for use in lighting, security, video doorbell, and more. In all cases, the most reliable motion sensors will be hard-wired or PoE, since they provide a constant power supply as well as uninterrupted communication.
Note that some wireless motion sensors have the option of receiving power over USB. Many wireless motion sensors behave more reliably when they are powered by USB power in this way, rather than by battery.
