That doesn't look radarey. Looks camera-ey. May have a laser to sense distance for triggering.
Tell you the truth, I'm getting a little paranoid/wary about being bombarded everywhere from radar. I started to get picked up by one of those roadside radar displays from about 1/4 mile away and had to wonder about that.
Then there's those microwave door openers in stores and stuff.
"They" say it's "safe," but what's the upper limit for "safe?" I know that microwaves will cause polymerization of things like egg whites and the vitreous humor of the eyeball, and any polymerization thereof is irreversible and cumulative.
And what's the lower limit for a frequncy being "safe?" Is there a sharp cutoff point for "safe" versus "unsafe?"
And did I read about birds flying through high-powered radar beams getting zapped?
Poo-poo my concerns if you will.
