With the rapid development of semiconductor technology, image analysis in the past that has required a large amount of computing power could only rely on PCs. Now, with DSP developed into an independent intelligent video sensor or embedded directly into a camera it can actively collect various on-site information which can not be achieved by other sensors.

The basic difference between the application of intelligent video sensing and general image monitoring is that image monitoring needs clear (high resolution) images in order to see the details of the situation.While the focus of intelligent video sensing is able to perceive whether a particular event occurred, the mechanism does not necessarily need clear images (except for license plate recognition and facial recognition).

"The type of camera needed for intelligent video sensing should be small with low power consumption, highly stable, long usage life, easy installation and maintainance, cost-effective, and it should be able to be set up in volume to capture information from every corner." Emphasized Tony Tam, General Manager of TDV (Triple Domain Vision Co. Ltd), "Thus, the various traditional, mature, and low cost analogue CCTV cameras are ideal for this application. The intelligent video sensors (iSensor/eSensor) and intelligent video server (iBox) developed by TDV are an ideal solution to help current camera products ready to migrate for IoT applications in the near future."
