Direct answer
Yes, segmentation is a sound security practice when it is designed without breaking required communication. A separate IoT, camera, or guest segment can limit a compromised device's access to work computers, files, or other sensitive systems. Simply creating another Wi-Fi name is not always sufficient, however; phones, controllers, speakers, televisions, printers, and casting protocols may need carefully allowed traffic between segments.
Define device groups and firewall rules, then test discovery, app control, streaming, remote service, and updates. Maintain an equipment inventory, remove unused devices, change default credentials, enable multifactor authentication where available, and keep firmware current. NIST's smart-home guidance and the FTC's connected-device guidance support these practices.
