Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

With the new presidential administration coming into the White House, will this be the year of advancing infrastructure? Will there be a diversified trillion dollar infrastructure project to jumpstart the economy as well as fill your schedules and your wallets?

A Protective Barrier

Optical fiber, like copper wire for communications, needs to be kept dry to maintain its performance. On wire, moisture causes high impedance and crosstalk. In fiber, it adds to the attenuation and may make fibers brittle and more susceptible to damage.

Video over IP Gains Ground

Live video has come a long way since the early 1990s. Remember the images of reporters filing news reports through the analog-transmitted video feed during the first Gulf War? It was shaky at best. But times and technology have changed and video streams are not even close to what they were then.
