Systems

 

 

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. 

Last month, I discussed the growing pains I have seen in fiber optics. Some of the problems have been issues with incompetent subcontractors, but poor network design seems to cause just as many issues. Why is that?


Integrated systems solutions aren’t reserved solely for surveillance, intrusion detection and fire-signaling technology. Audio is the bright star on the horizon, especially as it begins to be leveraged more fully on the network.

As building intelligence becomes a mainstream demand in small to mid-sized buildings and companies, contractors must find ways to offer solutions without crippling startup investments.

The fiber optic industry is going through growing pains. As nationwide connectivity projects such as Google Fiber have accelerated the deployment of connected cities, the realities of running cable throughout America’s communities is proving a challenge.
