no I am in North London

by high security communicator you are talking redcare kinda services to connect to? are there other alternatives - a service which accepts a signal from such high sec comm device and transforms this to a phone call/text? anyone you can recommend? also do you sell communicators like that?

understood. thank you

thank you. are Infinite or Honeywell Galaxy 2-way? I can find only Visonic to say explicitely it is 2-way.

I saw a website similar to ebay recently. One local guy is selling GSM jammers for a tenner or so. He had 10K feedbacks by the time I found it. I guess 9999 of them was bought by thieves. Hence I understand GSM alarms are placebo for the owners... My question however - the wireless alarm sensors work on frequencies close to GSM 300-900MHz right? So it should be fairly simple to mask sensors with a jammer. As long as the jammed sensors cannot send alarm signal to the control panel - the whole system is pecked... is this the right picture? (I mean the more expensive alarms must have somewhat a poll interval alarm but I guess that should be around 2+ minutes - in that kind of time experienced guys can get most of what they wanted anyway).....

I think before - the best way to protect a window was to have a foil running around the glass.. Now I see a lot of electronic gadgets. However I am not sure how reliable they are. Say vibration sensor. I guess it is easy to cut glass above/below such a sensor with diamond cutter and simply disconnect it with a knife or undo latches and open window slowly or get through not disturbing the sensor using the hole... I mean - if the intruder is an idiot and will smash the window with a brick it works but otherwise - unlikely... am I right? is there other means to protect glass area? If the window is obscure and design and beauty considerations arent important - is there more reliable perhaps mechanical sensors?

I understand that conventional unmonitored alarm system has 3 major components - keypad (to arm/disarm etc),control panel (which monitors sensors and sets an alarm when armed), dialer (if you want to call outside). I understand 'proper' system will have keypad separated from control panel and the control panel should be in a metal box in less accessible and visible place. so it should take sometime for an intruder to find it and smash it. however the question - what do you do with dialers? there are not a lot of places where the land line socket can be placed in the property hence intruder simply need to go quickly around (dialing a number and playing message should take at least 20-25 sec) and smashing the dialer. Also I understand it is fairly easy to cut US land line.. How protected land lines in the UK ?
