Wireless alarms.

You won't find any decent wireless alarms in Screwfix.

Erm, right.

Yale = bag of s*it. Offerings from only decent wireless alarms I can think of aren't readily available in DIY type places. Txecom Premier and radio expander might be the best to go for for ease of use and installation, reliability and availability.

Oh well. Hard wired it is then.

It's too easy to jam wireless alarms anyway. You can hack one of the transmitters or even a matched keyfob to transmit at higher power continuously and it jams the whole system. Even if it has an "anti-jam" feature (sets the alarm off) the owner will soon turn the system off if it just sits there in alarm mode continuously.

Nope, but I have used TLCs Infinite range. That does seem quite good. Fairly pricey though.

Keep forgetting about those. THe Infinite is meant to be reasonably good. FM Electronics do some decent wireless kit too.

Yale are crap. I installed one of these last year:

That should be easy enough to cure.

I wouldn't worry too much about the "jamming" problem. Only a very well organised burglar is going to attempt to jam an alarm system and then only if the contents being protected are of high value. The large majority of burglaries in domestic premises are carried out by relatively low-intelligence people who are certainly not going to carry jamming equipment with them.

Yeah, if I rewired it all in screened cable!

I'd rather just put in a new system and avoid any repeat visits.

Not necessarily. You could try fitting ferrite beads to the wires coming out of the alarm box to increase their self-inductance...

I get the feeling burglary has gone out of fashion since nothing is worth much any more and people tend to take their phones and laptops out with them

Except by the police:-

Not necessarily - a simple filter should do the business.

And if that was the case the contents would be of interest to the insurance company who would insists on a grded alarm which you couldn't fit yourself anyway.

I installed the Visonic PowerMax+ system. It operates in a frequency spectrum reserved for security devices - 868MHz I think - which is supposed to all but eliminate interference and false alarms.

Fully monitored system for tamper events and low battery warnings etc etc.

It's not cheap though - bought mine from
