Smart Transportation

In recent years, the rapid development of networking devices has made it easy to install high-performance and high-definition IP cameras in every corner of the metropolitan areas. This has enabled the government to analyze real-time or recorded video images to efficiently fight violence or any terrorist attacks with less costs and manpower support. However, when it comes to highway surveillance implementation, the situation becomes more complicated. Highways run across several cities, making frequent patrolling by the police impractical and inefficient when an emergency occurs. Before successfully setting up highway surveillance, there are several challenging factors that need consideration.

Challenges

1. 1. Devices placed outdoors face a heightened risk of being struck by lightning, experiencing ESD, or suffering from power surges.

2. 2. If these devices fail in a single point, it may not be possible for an engineer to quickly resolve the issue at a highway field site.

   3. Unstable or fluctuating PoE power may also cause damage to connected devices.

3. 4. Outdoor temperature can vary widely in highway areas, with temperatures inside a metal junction box reaching up to 85°C in summer months, and dropping to -40°C in the winter.

OLYCOM'S Solution

1. 1. Provide industrial switch which has passed the industrial certifications.

2. 2. Support various managed rings and bypass, when one place has problem and woulnd't affect other palces.

3. 3. Provides dual power with wide voltage input power for industrial POE/non-POE devices in 24/48V (9~57V).

4. 4. Supports industrial operating temperature (-40~85°C) with rugged design.

So OLYCOM suggests to use industrial POE managed switch for outdoor.
