Glass breakage detectors in to-days world are very reliable. However it's not beyond the realm of possibility, your neighbor might have a defective one. Tell her to call her alarm installer to check her entire system out.
Caution: Yes, glass break sensors are an excellent enhancement to your home's full perimeter security system, but only when incorporated with magnetic door and window contacts. At no time should they be substituted for perimeter door and window contacts.
