DOT1For the last 15 years transportation agencies have used analog video solutions to watch interstate roadways. Cameras were mounted atop poles as high as 100 feet high and installed every mile to two miles apart. All of the wiring for the camera and the network aggregated at the bottom of the pole in an enclosure that is rarely cooled by anything other than a vented opening. The equipment in the enclosure accommodates getting the analog video and NTCIP control serial data onto the network so that the RTMC (remote traffic monitoring center) can view and control the camera. Today we are faced with migrating this type of installation over to a digital device. The good part is by doing so we can reduce overall cost and efficiency.

To help with this migration path Nitek has manufactured a product called Etherstretch. This product allows for the coaxial cable to be maintained by turning it into a 100MB ethernet path. The Nitek EL1500C is approved by the state of Florida for use in any system for these purposes. Here we show how it might be installed in a lowering system:DOT2
