Alarm & Security


Wednesday night, 10:32 p.m. A signal from the Agnew residence at 1107 E. Rochester Street drops to your monitoring center, indicating a break-in. The address is in a new subdivision, and it’s unclear which authority having jurisdiction (AHJ) should take the call.

It’s a common occurrence. Jurisdictional boundaries are constantly in flux, and maintaining a pristine database is a labor-intensive, painstaking and costly process for most organizations.

Having access to the most accurate contact information for police, fire, medical and PERS—all in real time—is key to delivering best-in-class customer support. The right data can speed response times, increasing your subscribers’ confidence in your service. Verified AHJ contact information optimizes the prioritization of call routing and creates efficiency within your organization.
