Looking to replace a very basic alarm.  The one that is there is from previous occupants and is proprietary to ADT, who I will not be using.

I need two doors, one motion sensor, one glass break sensor, and maybe another contact on the door to the safe.  A minimal inside siren is fine, and an outside siren with a strobe.

The place where the basic prepackaged systems seem to fail is the connectivity.  I am trying to avoid activating a land line.  I will need to add an IP card and possibly a radio backup, or buy it already included.  The alarm will be monitored.

Any system recommendations from the pro's or otherwise experienced.

Shoot me a PM. ADT has proprietary and theren there is  the PROPRITIARY. A lot of it is just privatelabeled. some of it realyl is rpopritiary.

Shoot em a pic of teh keypad adn I will help you out.
]I been doing this for 16 years.

Install an Ademco Vista, replacing only the panel, and you can re-use all the ADT sensors (99%; most ADT proprietary systems are based on Ademco Vista).
