As the #1 home alarm company, ADT has an impeccable reputation for their 24/7 customer monitoring. Also, they were named "Best Buy" by Consumer Digest and have packages for less than $1 a day.
Their wireless security system offers the same service and response time as the older hard-wired systems. As they are wireless, it's easy to add or relocate the monitoring sensors. A added feature is that the wireless system can be used to control lights, garage doors and some appliances within the home. Their 2 way voice option requires a land line telephone so that you can speak to the monitoring center from any room.
There is no question; ADT is the security system for me.
