    When we decided to install a system, Erker Security was very helpful in describing about the pros and cons of different options, and in matching their recommendations with our needs. They were amazingly flexible with the installation itself, accomodating the stepwise process of a home addition. Our system is easy to use, and just right for us.

    Erker Security is probably on the pricier side, but in this case you definitely get what you pay for. In my case there was an issue with my house that prevented an alarm system from being installed 'as normal'. The issue was unknown at the time they sent me a quote for the installation of an alarm system. Despite a lot of surprises in my house along the way, they still honored the original quote. They went above and beyond to get the system working as intended.

    Among other things, they came to my house three more times then they expected to (including coming once after-hours), and they added some additional equipment to the setup that they did not charge me for. All the workers I interacted with were extremely friendly and personable, and the steady communication from them at every stage of trouble-shooting the issue was amazing. I never felt like I was in the dark, and I never had to struggle to get into contact with somebody for an update. I couldn't recommend Erker security enough - if you work with them you won't regret it!
