Douglas Investigation & Security Co. Ltd.

24 HR Monitoring

Welcome to Douglas Investigation & Security Co. Ltd.

24/7 Monitoring & Alarm System Installations

Specializing in the installation of burglar and fire alarm systems, Douglas Investigation & Security Co. Ltd. services customers throughout Prince Edward Island, Nova Scotia, Cape Breton and the surrounding area. As a locally-owned and operated business that is not part of a large franchise, we’re able to deliver personable, one-on-one service the way our customers want it to be delivered. Service calls are usually completed the same day and we do our own local monitoring instead of contracting it out.


We Can Help You Use Your Existing Alarm System

Have you moved into a property with a pre-installed alarm system and want to activate it? Or you own a security system, but are looking for a 24-hour monitoring service? Whatever the situation may be, we can take on the current system installed by any alarm monitoring system company. We can also help you decide whether to reactivate or replace your existing security system.


For a quick takeover process, we need your current equipment details such as brand and model. If you have visited our website and are located at a distance that is reachable within three hours from the Halifax metro region, we would be happy to come and collect the information free of cost. Contact us for a free quote of our services.


Over 43 Years of Experience

Fully certified with over 43 years of experience in the security and alarm systems industry, our company was founded in 1968 by the father of our current owner Robert Douglas. Robert inherited the business from his father in 2004. We started conducting our own in-house security monitoring in 1979, and to date, we have worked with just about every type of security brand. Even after four decades of dedicated service and a commitment to excellence, we always have room to grow. We plan to continue to serve our customers with unsurpassed quality and selection for many years to come.
