Chances are you have encountered a wiring mass—or mess—somewhere along the road when installing voice/data/video or information transport systems. Year after year of adding, changing and rewiring may have left the plenum with little room for additional wiring and cabling. READ MORE

For traditional burglar alarm installers dealing with intrusion detection and monitored systems, it came as no shock that voice over Internet protocol (VoIP) was not the end-all and cure-all it was originally purported to be. But that’s the reality of emergency communications in some instances. READ MORE

Access control is a logical product to integrate. Technology continues to advance, especially in networked solutions, smart cards and biometrics, offering new capabilities and more application possibilities than ever before. It is a logical product to expand and add at existing premises, such as a college that requires single-door control or a campuswide networked solution. READ MORE
