•

Device should only be used in a personal home network.
Device should not have a publicly accessible IP address.
Do NOT use port forwarding to access a device from the public internet.
A device should be on its own network segment. If your router supports a guest network
or VLAN, it is preferable to locate the device there.
Use the strongest Wi-Fi encryption available in the home Wi-Fi network, such as WPA3or WPA2/3 with protected management frames.
Schedule regular reboots of your routing device, smartphones, and computers.
Ensure that unauthorized individuals cannot gain physical access to your devices orregularly inspect the device for visual clues that may reveal a tampering attempt.
