We often hear that one of the great advantages of IP over PSTN is the increased speed of alarm signal transmission. Whilst this is partly true, alarm installers need to understand the different stages of an alarm signal transaction in order to take full advantage of this available speed.

Typically, from the time an alarm panel is activated, it takes approximately 10-15 seconds to dial the telephone number and send a DTMF or FSK signal over a PSTN line. When an IP dialer capture device is used, it listens for the telephone digits, ignores them, plays a handshake, takes the signal, plays a kiss-off and then transmits the signal over IP. Even though the actual transmission over IP might take only a couple of hundred milliseconds, the whole process takes approximately the same time as it does over PSTN. So where is the speed advantage in using IP...?

It’s been a couple of years since I’ve done this, but a few days ago I decided to draw up a list of my favourite technology from the last 12 months.  As I asked myself what items I had been using on a daily basis, the ones I really couldn’t live without, I came to the realisation that the top ten or more technologies I was thinking of, came from just two companies!  It probably won’t be too much of a surprise to find out who they are, but here is my shortlist for “Top Tech” in 2007…
