Where can I get a glass break detector.

The security guy who installed my door alarm and cell backup package
programmed the door alarm security for 5 zones but he said the cell backup
package will only give a signal to the central station only as Zone 1 no
matter which zone is broke. He said the problem is he cannot get the ademco
alarmnet cell backup system to program with ECP.

Do you  know if this guy is really a security expert or just bs'ing to me.

Is there any additional layer of security backup on top of the cell backup
package. Assuming the perps are sophisticated security experts, what other
alternative backups or measures can one take on top of the cell backup
package.
