ADT has been around for a very long time, has a great reputation and was the first alarm company name we thought of when seeking to find our home security system. HOWEVER we feared the cost would be much higher when seeing ads from so many other companies and DIY options available. So we checked every source out there in depth before deciding what was the best for us. In the end we found ourselves right back at ADT. I am employed within a police department for over 30yrs now and knew what all I demanded with a system, so cost was the main purpose for the lengthy search. My review and testimony would be that ADT should, at least, be a company to research, because what we found is that there are many options on how and what price to equip your home with the best system and keep it at the price you choose. So, after a lot of negotiating (with only the installation company who sells the equipment and does the install that works with ADT) we found that the home visit was worth the lengthly time it took to get to finally what we wanted at a price we wanted. ADT itself is a great company however their installation company salesman reminded us of a used car salesman, with that being said, we have now purchased the perfect alarm system with everything we insisted upon and at the price we wanted. Once the price was settled and in writing on our contract, we finally enjoyed our salesman! So just understand the salesman's job is to sell and install equipment, he is a great guy however still a salesman doing his job. Just know that YOU are in control. So in the end we purchased everything we wanted and now have the best monitoring alarm company out there, in our opinion. So, if ADT, the best company out there in our opinion for our protection, is the company you want - go through the home visit and car salesman to get it. We couldn't be happier. After all is said and done now, we have the best for a price that equals the rest!
