Safest wireless security technology

[Tom Redstone]

Door lock and camera systems connecting to an Internet router, using Wi-Fi Z wave or whatever else is out there? Something that is unacceptable unable encrypted. What’s the best or safest?

A wire is the safest  Cameras are unlikely to support say wpa3 enterprise, which you could then use something like eap-tls, and even if not it can do 192bit . WPA3 does use SAE (Simultaneous Authentication of Equals) vs PSK etc.. Do your cameras support wpa3? 

Your best option for wifi would be wpa3, not the wpa2/3 compatibility mode.  This brings SAE and also PMF (protected management frames) And set your password to something long and complex.. That is if your iot devices even support wpa3 at all.

As Budman states, WPA3 is the best Wireless option you have for Cameras, Z Wave, Zigbee etc. won't have the bandwidth for Video streaming. Ethernet is more secure still and convenient if you use PoE cameras as you then don't need a separate run to the Camera for power. As for the others, I have both Zigbee (Philips Hue) and Z-Wave (Ring Alarm system) on my network, I have segregated that part of the network (the bridges/hubs still connect by wires) via VLAN and called it an IoT network which is about the best you can do.

I vote for wired cameras and keys. I don't ever think I'll trust a wireless door lock.

Probably prioritize devices with regular firmware updates and two-factor authentication.

I attempted to update the My Wifi security key months back,  then my Family members couldn't figure out how to reset the Google Nest Camera to accept the new Wireless Key,  took a whole day of screaming and yelling to get it working again,  in the end i just put the Old Key back in service, and was like i'll figure that part out i guess again in future here. 

 

Ideally i'd like to update the Wifi security key every 6 months, but might be a pain with devices i don't have direct access to--like Google Nest camera,  Other Family Members Apple Iphone,  Sisters Apple Iphone when she visits.     

Guess i'll attempt for 1 time sometime soon, and pray it goes well that time, and they know how to reset the Google Nest Camera to accept the NEW Wifi Key, i have no idea what Wifi Security mode it even uses, as of course stubborn sister was like i'll set it up.  

Just don't want my lower gi ulcer returning when i deal with this issue again at some point

Yeah, wired setups are always the safest if you can run the cable. For Wi-Fi gear, WPA3 is definitely the way to go with a long random password and PMF turned on. Keeping IoT stuff on its own VLAN helps too, just in case something gets compromised. I’ve seen the same thing, most problems come from outdated firmware, not from the Wi-Fi standard itself.

Not to be too pedantic, wpa3 requires PMF (Protected Management Frames). If you run in say a wpa2/wpa3 mode then they become an optional choice.
