Consider a video based system, with self protecting cameras. Less wiring, better security. No need for a service company, and you can get a dialer to call (you, or whoever) when there is an alarm.
I have to disagree strongly on the *No need for a service company*. A person can not be counted to be awake, aware, and be at the ready at all times when a incident happens.
A CS (Central Station) is staffed and ready to respond 24/7/365.
Their only goal is to monitor and react to ensure your safety and that of your property. Those who choose to go self monitoring to reduce overall costs are simply focused on costs alone.
Not, about the value and the level of true protection a CS does provide. Keep in mind many insurance companies reduce your insurance rates if you elect to have your home monitored by a CS that is approved.
When there is a fire and the fumes over take you or your loved one's. Who is supposed to call the FDP??
If you're out of cellular range, or the battery is dead. How will you hear the phone call?
When you're in a underground parkade, shopping mall, elevator, or any number of dead spots?
At the end of the day a CS is exactly like insurance. No one wants to pay for it but sure as **** you're happy you had the coverage during a disaster event.
Since you live in the USA you can find CS for as low as $9.99 per month so no reason not to have a CS watching over you, and your loved one's
