Sonitrol provides businesses with a single source of integrated, state-of-the-art security solutions for intrusion, video, access and fire, all backed with professional monitoring by experienced, trained personnel. Our technology sets us apart. The ability to verify an alarm event in real time gives Sonitrol unrivaled credibility with local law enforcement. That is a key advantage as a growing number of municipalities pass Verified Response regulations requiring verification that an intrusion is actually taking place before police will dispatch personnel to the site. Sonitrol has the best apprehension rate in the industry - and the fewest dispatches for false alarms. In fact, in January 2006, Lehman Brothers named Sonitrol "the leading alarm verification company." And our integrated components allow us to customize a solution that can expand easily as your needs grow.

At our January CIRC meeting, we had the opportunity to hear from County Executive Marcus Henry, who provided an in‑depth update on the ongoing New Castle County reassessments. His discussion shed light on several critical areas for our industry, including the impact on commercial (non‑residential) split school taxes, the structure and expectations of the appeals process, and the resources the County is putting in place to support property owners and businesses throughout the transition.
He also highlighted the County’s broader efforts to strengthen economic growth—reinforcing the importance of collaboration between public leadership and the commercial real estate community as these changes take shape.

A valuable and timely conversation for all of us navigating the evolving landscape in New Castle County.
