Direct answer
Hardwire stationary, high-bandwidth, power-critical, or infrastructure devices when practical. Common candidates include wireless access points, surveillance cameras, recorders, televisions, streaming devices, workstations, automation controllers, AV processors, touchscreens, and equipment racks. Power over Ethernet can carry data and power to supported access points, cameras, and interfaces through one planned cable.
Wi-Fi is appropriate for mobile devices and products where cable is impractical, such as phones, tablets, wearables, and some retrofit sensors. Hardwiring reduces radio congestion and creates a more predictable path, but every cable must still be correctly specified, terminated, labeled, tested, and connected to suitable switching. Prioritize reliability and traffic type rather than maximum theoretical speed.
