It's been echod several times in this thread already but:

Wireless and security are oil and water. They do not mix. This goes byond wifi. If your security system has wireless sensors (door, window, motion) - you aren't secure. Please do not buy smart locks.

Wireless cameras are not security - they are a convenience. A convenience for checking on the kids in the back or seeing if that package got delivered.

If it's not wired and powered it is at best a scarecrow and at worse an indicator that you have money and you feel secure.

That is a true statement. You can't have both securtiy and wireless (convenience).

Every wirelessly transmitted signal, whether it is your network signal or bluetooth, can be intercepted from afar. It is even possible to encrypt the accoustic signal emitted from a needle printer and determine what has been printed because every letter/word emits a specific sound pattern. Sound travels wirelessly. This link from 2009 refers to that. Unfortenately it is written in German and I didn't find anything in English, but you could translate it.

Edit: typos 2 nd Edit: Addition: Needle printers are still in use - at least in Germany - for printing prescriptions at doctor's offices, among other things. The paper used for that provides a (physical) carbon copy.
