Well as a radio comms and broadcast engineer I wonder why I have most
everything here wired rather than "Wireless"?..

Same here. Years of experience with radio mics. ;-) Only reason to use a
radio link is where it's impossible or inconvenient to use a cable - like
say with moving objects. None of this applies to an alarm. Or a doorbell.

Hear, hear. As an aged IT bod and radio ham, I'd run wires.

I'd run wires as well. Wires are trustworthy; radio isn't.

Unfortunately, this is not always the case. The wiring can act as an
efficient aerial system on the lower frequency amateur bands. If they
are not designed to operate in moderately high RF fields, wired systems
can be very susceptible to RF interference, and go off. If your nearby
radio amateur is not likely to use the 70cm band, you're probably better
off with a wireless system (even a crappy one on 433MHz).
