know N numbers for UAV's flying near SO Cal?

Anyone know N numbers for UAV’s flying near SO Cal?

I think I read McCready or someone was going to be operating some of the larger Survellience UAV’s around southern California for something.

Can’t remember if it was post 9/11 security or environmental or fire watch or something.

Anyway just wondered if anyone knew what kind of N numbers those things have if any?

And how small to they have to be before they don’t need any N Number?

The local LA County sheriff was going to get a handheld UAV but was stopped by FAA I think.

Be interesting to track one and go outside to see it in flight.

This one isn’t a UAV Mark…
