I purchased the Live Watch Security system approximately one month ago based on internet reviews. I worked up the system I wanted on their web site and then reviewed the details with one of their customer service representatives before finalizing the purchase. They could not have been nicer or more helpful! The system arrived promptly and (though I had slight concerns) proved to be very easy to install. I have a vintage 1936 home with plantation shutters on all windows which made installing some of the sensors difficult. However, the instructions provided alternate installation options which worked like a charm! The system works perfectly and the customer service is with the best of the best! I highly recommend this company and security system.
