I am glad to see you are still deeply interested in QTK however you are 100% wrong on this post.

Most if NOT all alarms now come standard with a dialler (which requires a land line)....and DO NOT come GSM ready.

GSM is an expensive way to have a monitored alarm and is the least favored way of doing so as it has many technical issues re coverage and ability to work if the network is down.


The QTK system does NOT rely on telephony to work and does NOT require a phone line of any sort.
