ADSL can be used but has the same problem as a phone line....can be cut.

The QTK system beats everything on the market by a mile as it is impossible to be beaten by intervention.

There are only 3 current methods of alarm monitoring

1...land lines

2...securitel

3...GSM

and all three have issues re delivery and all require telephony to work.

and the latter two are cost prohibitive to residences.

good to see you are still worried Alex.

i hope your staff know what you do all day long.

LOL
