Invision Security Group is a leading provider of commercial, industrial and government security systems in Philadelphia, PA and beyond. We design, integrate and support over 3,000 clients in the tri-state area. A burglar alarm system consists of a series of electrical components that are connected to a property. Via sensors and contacts, they detect movement or the opening of doors and windows, after which a loud alarm is produced to alert those nearby of the unauthorised entry. Invision Security provides a seamless and scalable turnkey solution for an entire project. This integration of services includes all aspects of the design engineering, CAD drawings for submitting and permits, all of the hardware, and followup service. The benefit to our customers is that they have a one stop full service provider for the entire project. Call us today or complete our contact form to schedule a free consultation with no obligation.
