Transition Networks Puts the Intelligence in Intelligent Transportation

Most major U.S. cities have a Department of Transportation (DOT) that is expected to keep people and goods moving safely and efficiently, all while being environmentally responsible. Given that there are 330 million people in the U.S., that is no small task.

Most DOTs leverage closed circuit television cameras focused on major traffic areas, allowing operations staff to observe traffic conditions at key locations throughout the city. The cameras may be re-positioned to view traffic from varying directions with the streams being particularly helpful in times of natural or man-made emergencies. However, given that these cameras may be spread throughout the city and located in hard to access places, when a failure occurs it can be a hassle for department employees to fix the issue in a timely and efficient way.

The Solution

Switch in box for DOT for ITS Application

Transition Networks has a growing portfolio of Power-over-Ethernet (PoE), PoE+, and PoE++ switches that can provide the perfect solution for DOT employees tasked with connecting cameras in order to monitor traffic conditions remotely.

Transition Networks offers hardened managed switches for ITS use in four and eight-port versions providing 30, 60 or 90W of power per port.

4-port <30W SISPM1040-362-LRT
8-port <30W SISPM1040-384-LRT-C
9-port <60W or <90W SISPM1040-582-LRT


All three switches are suitable for powering sensors and intersection cameras and the switches’ small form factor make them ideal for fitting into a traffic pole cabinet. And each of the switches are certified to operate in hardened environments such as outdoor enclosures.

Most importantly though, each switch has Auto Power Reset (APR) and embedded Device Management System (DMS) software, making it easy for DOT employees to troubleshoot issues with intersection cameras remotely.

APR automatically monitors and resets the connected powered devices in case of power glitch to ensure consistent power availability. DMS provides discovery and mapping of powered devices and allows for troubleshooting of cable and IP connections for easier management and maintenance of the network. So, by using the DMS instead of visiting each traffic control box, the intersection equipment can be rebooted, adjusted and managed all from a mobile device in a city’s traffic management center, significantly reducing the hassle in repairing a traffic monitoring failure.

Whatever your traffic camera needs are, Transition Networks has the right switch for you. For more information on how Transition Networks can help with your surveillance or intelligent transportation system needs, visit our solutions page.
