Does anyone have any experience with any make of transmitter and
receiver system which is secure?

Any suggestions?
You could try this lot http://www.garage-door-remotes.co.uk/

I did come across the site, but with minimal knowledge and the shear
breadth of names covered for spares I didn't find it didn't much help to
make a decision. Having revisited their site their upgrade page is of
interest.

All depends on how secure you really need it. Any system can be broken
so should be thought of in terms of how long the bad guys will need to
get in compared with going round the back and going through the window
or similar.
If the contents are insured, then the insurance co may take a view on
the security needed.

Security is important, but with a sensor hidden it wouldn't be obvious
there was a wireless means of entry, or the brand.

As you say, security is relative.

Many thanks for your reply.
