Cayer Security Services specializes in designing, installing, and maintaining burglary alarm systems throughout Maine.

Whether you are looking for a basic alarm system to protect your home, or a complete custom system including multiple components such as smoke detectors, video surveillance cameras, and driveway detection systems – give us a call and let us help you protect what matters most.

Most home insurance companies will give you a discount on your home insurance if you have a monitored security system. Plus, with Total Connect technology, you have the option to arm and disarm your security system from your smartphone or any computer. If you have Total Connect cameras, you can even check in on your home – anytime, anywhere.

We don’t lock you into a contract like some other security companies do. We are a local small business and customer service is our priority.

We have had good luck with this company. They came and installed our alarm system several years ago and did a nice job. The one time that we had an issue we got an appointment quickly and the issue was resolved in a professional and timely manner by the owner Bob. Would highly recommend.

We had Cayer Security recently installed in our home. We have a big house with places I cannot see. I sleep better knowing we have Cayer Security watching over us.
