5 star service from Alarm EngineeringAlarm Engineering is a top notch company. Dave Mueller put my mind at ease by being very thorough and spending his time going over the security system. I purchased the system for my mobile home and not once did I feel substandard. Usually when you think of security systems, you correlate that with very expensive homes. Thank you Alarm Engineering for making me feel safe!”

“I was a police officer in New Jersey. I went up thru the ranks and made it to chief of detectives of a county prosecutor’s office. Being involved in law enforcement for 25 years I have seen many burglaries and strong arm robberies. We lived in rural Hunterdon County in New Jersey, a very affluent area. Even while living there I had an alarm installed in my home. Once I retired in 2008, we began looking to move to Delaware. In 2011 we built a new home in Delaware. Even though this area is very nice, I felt based on my law enforcement experience I still needed an alarm in my home. From speaking to one of my neighbors he recommended Alarm Engineering for the alarm. I contacted David Mueller and he quickly made time to come to my home and explain all of my options for the alarm installation. The price was good and the components he recommended were just what we needed, so we went ahead and had it installed. Since we have had the alarm, we only had one issue with a faulty window switch that caused an activation. I contacted David and that afternoon a technician came to my residence and correct the problem.

Within the past few weeks I contacted David again and asked if there was any options to remotely control the alarm system from my phone. He recommended a cellular device to be added to my existing system. We went ahead and had it installed. I don’t know why I did not get it installed with my initial installation. This device is great. I am very pleased with my system and the company that did the installation.

Alarm Engineering is a great company to deal with and David Mueller is a really down to earth kind of guy, no high pressure sales and always gets back to you right away.I am a very pleased customer and would recommend Alarm Engineering to anyone looking to have an alarm installed.”
