Re: 15. Wired / Wireless alarm systems?



What?. I saw them at IFSEC. I was there. I was shown them. They exist.
Period. I'm not about to sit here trying to 'convince' you that they exist.
They do. live with it.

The transceiver based systems I saw were on 868 although I seem to remember
at least one that came in 424 or 868Mhz flavors.

Paul, I have no desire to get into an argument with you. If you do not
believe me then that's that. I know this year will see quite a few
transceiver based alarm panels coming onto the market as I saw then
showcased at IFSEC. Whether they are available today I don't know. I just
know that they exist. I will be proven correct. As to what brands...I can't
remember. I'll enquire and post back.
