I assure you

When you step into a full body scanner SOMEBODY gets a look at your shrinky-dink!

When we fly we are forced to let some stranger see our junk with the full body scanner

Gotta make sure no one is smuggling a full sized tube of tooth paste up their ass

Seems reasonable given that

I have an Aqara doorbell camera thats been really nice

I am not 100% sure about their privacy but the camera can record local as well as to iCloud when used with HomeKit

My IoT approach for the last 7 years has been HomeKit or DIY and I have not been disappointed too much
