As the growing usage of microcomputers and electronic devices, the electromagnetic environments become comparatively complex over many applications; the external interference produced by unwanted electromagnetic energy produced by electromagnetic field, statics, lightning strike, or voltage variations may cause the electronic devices to fail, and this issue is eventually inevitable as it accompanies system integrations, and holds accountable to electronic manufacturers and project planners.

The concept of IP security surveillance has been gradually adapted in substations, factories, traffic control and other critical infrastructures. A complete surveillance solution consists a large number electronic devices along with higher frequency range and power rate, resulting the field site expose in high electromagnetic interference. The connections made by various medias could degrade or disconnect in the process of transmission, due to electromagnetic emissions and radiations.

To make sure the accuracy and efficiency of data flow, it is crucial to evaluate the operational risks and choose the most reliable equipment accordingly, reducing the cost of ownership at the same time.
