Monitored versus self-monitored
A self-monitored alarm sends the alert to your phone and it is on you to decide what to do, which is fine and free of a monthly fee, as long as you are reachable and willing to act. Professional monitoring means a service watches for the alarm around the clock and can call you, call a keyholder, and dispatch police or fire, which is what you are paying the monthly for. Whether that is worth it depends on whether you would rather handle an alert yourself or have someone whose job it is to respond.
What monitoring really buys you
The honest value of professional monitoring is the times you cannot respond: you are asleep, on a plane, in a meeting, or it is your business at three in the morning. That is when a monitored system does the thing a self-monitored one cannot, which is get a response moving without you. If you are always reachable and comfortable handling it, self-monitoring saves the fee. If you have a business or you travel, monitoring starts to make real sense.
Licensing is required here
In Texas, alarm companies and the people who install alarm and monitoring systems have to be licensed and registered through the state, and that is not a formality; it protects you. Before anyone starts wiring your home or business, ask to see the company license and the installer registration. A legitimate outfit shows it without hesitation, and anyone who cannot or will not is a reason to stop.
