That's something that's making me curious about this whole thing. The house that I'm buying is already equipped with ADT, and as long as I keep it in service, I get a discount on my home insurance. Although, ADT is something like $30-50 a month depending on the level of service, and I think the discount is only about $15 per month. So, if I went with Simpli Safe, I've got an upfront negative drawback in that I have to pay for the hardware, but it's priced well enough; however, even with their top package, I could save money per month.
It's tough to figure out what the "right" choice is. In my case, I've lived in the same home since 1987 and I had an alarm system installed sometime around 1990 after a break-in. At that time, everything had to be hard wired, wireless wasn't even on the radar. The panel, the guts, have been replaced and there is a story behind that but all my sensors are original from the initial installation. Except for one of the magnetic door switches I replaced today.
I'm not going to rip out or disable what I have to purchase anything that's new on the market. It makes no sense. What I have performs just as I need it to. If needed, I would replace the guts of the system again or individual sensors. But I would stay hard wired because to move to wireless, replacing the sensors I currently have would be very expensive. Easily over $1K.
I have three swing doors on either magnetic or jamb switches.
I have one slider on a magnetic switch.
I have two motion detectors.
I have seven windows that are low to the ground with glass break detectors.
I have four basement windows protected with what are essentially trip wires.
I have one smoke detector.
I have one rate of rise heat detector next to the furnace in my unfinished basement.
I have two keypads with panic buttons for police, fire and ambulance.
I have an extremely loud siren.
Why trash all that for a new system? But that's my situation.
When the guy that sold me my system originally was out explaining it to me he made a lot of sense. He pointed out the desirability of keeping the bad guys out of the house altogether. Why take the risk of having a confrontation of some sort? That's why the perimeter is highly protected and two entry doors are on a delay to allow for entry and disarming, but everything else will trip instantly. The motion detectors are really just in place as a failsafe.
The typical burglary is performed by drug addicts and is done during daylight hours. They are looking for items to steal that they can sell for pennies on the dollar to fuel their drug habit. These are not the smartest people. Put up a sign, put on stickers but the alarm itself should be very loud, in every way possible should go off instantly and should be backed up by the dispatch of the proper authorities. Hopefully they will be deterred. But if not, they should not be given free reign. When I got broken into, the bastards opened a can of tuna, got out some bread and made themselves some sandwiches, plus stole everything they could easily resell and damaged the door jam kicking in the door.
