A vote for FrontPoint Security. After looking at the top 5 I decided on FrontPoint for several reasons.
They use a national monitoring firm called Rapid Response;
Central Monitoring Station :: Rapid Response Monitoring Systems and You!
For those with more than one system this becomes an issue of significance.
Most of the others use regional providers.
Their control system is by GE.
Their consultants are 5 star witout a doubt. No pressure to sell. ONLY help you determine what type(s) of coverage create the most comfort for the customer.
The do it yourself is extremely well packaged and the clear and precise step by step set up and operate are flawless.
It was also important to me to have remote capability via my iphone.
I would not by a hard wired system, hence mine had to be cellular based.
The after the sale customer support 24/7 is some of the best I have EVER dealt with. Every single person is well trained and knows the product in detail.
Here is their website:
Wireless Home Security Systems | Frontpoint Security
They have three different monitoring plans to choose from.
Technology, quality and customer service one would expect in such a business.
My consultant asked me what was going on in TV as they have been getting a significant number of requests in the past few weeks.
Good luck
