Extremely pleased with the professionalism in installing the system. My home already had motion detectors and window/door alarms so they just replaced ones that weren't working and upgraded to newer unit since the one in house was approx 20yrs old. I can arm and disarm the system from my iPhone as well..super easy to use! Had 2 false alarms as my daughter forgot her PIN to disarm the system and I received a call within seconds from the monitoring company. The person who installed the system showed us how to use the system both on the keypad, laptops and smart phones. I would totally recommend Proper Guard!
