using paradox also. installation done by MMC. service was pretty good - they did a lot of finetuning and the system is really complex. so many things you can set i think i still dont know how to harness its full potential. its very very reliable, no defects so far. just one small problem in the past years where i called the importer and they fixed my setup on the spot (no charge, mind you). i especially like their petsafe perimeter sensors. once setup properly, you pretty much never have a false alarm. only once or twice a family of musangs triggered it. can link to security company, make the unit call you or your balai polis around the corner....

i think personally i'd buy it again but it's indeed one of the pricier options.

i got mine from MMC - quite OK. bought paradox pet safe sensors all around the house, can ditch any further sensors in that case. they are pretty damn good. only thing not really from paradox was the siren but what gives.
