the solar tat is upto 1km in range, (radio, not the the beam pair)

 

the visonic tat is a pir for back garden, the sort of size with neighbours with cats, balls ect....

 

I suspect either rigged up make a alarm will just piss you off until you disconnect it....

Are there any reliable alternatives to protecting the perimeter?

 

optex beams & sensors...

 

I don't like outside detection, 

Are they similar technology to my original post ?

Who were you expecting to call? I get the logic, but in order to be able to give advice,it would be sensible to understand the risk. 

Are you expecting to be targeted specifically? Could it just be that your concerned about opportunists? Have you already had someone enter your garden?  I have done several projects of this nature, and my advice would be its expensive to do it properly, and if you dont do it properly its just a waste of money.    

I am looking at a layered approach, starting with physically securing the perimeter the best I can and then working inwards. House alarm is the last line of defence, if that goes off they are in which is what I am hoping to avoid.

BTW - I am not planning on doing this install myself, I am just acquiring knowledge so I know what to look for with a supplier.  

 

I have completed two online inquiry forms for two reputable local suppliers recently and neither of them has contacted me, the alarm business must be booming.

Adjust watch by 20 yrs & welcome to the alarm trade, they've probably not printed you email out yet...

What security to you have already?

I assume that you want this to be an early warning system while someone is in the property?
