Sorry for the belated reply.
I have looked at Texecom before and actually consider their keypad to be one of the ugliest out there. They also seem to have far less integration options than a DSC PowerSeries like sadly almost all panels although I believe they are or are supposed to be offering an API for their system.
I agree that DSC keypads can be dated but really no more than 99.9999% of other alarm systems in that it is ‘ye olde’ numeric keypad - like Texecom. There is an LCD touch screen keypad available for the DSC unlike 99.9999% of other alarm systems but in reality it adds very little more and still has an on screen numeric keypad.
So ugly and primitive are most alarm systems (numeric) keypads that one would almost prefer to be robbed than have one right where visitors would see your poor aesthetic taste.
It is amazing in this era of touch screen displays ala iPhone and iPad that no alarm system has a touch screen display that would display a plan of your house highlighting where a sensor is that has been triggered. This is something that I believe has been in TV/Movies for years but sadly not in the real world.
Even the so called new, modern, Internet orientated smart alarm system makers have failed to progress beyond offering a basic ‘app’. That is Abode, Verisure, Boundary, Ring, etc. etc.
