IoT applications are being hailed as the future trend of technology application development, where the goal is to grasp the real time status of people and things, and upload large amounts of data to the cloud via a ubiquitous network to obtain important information through strong computing power to effectively monitor and manage.

For the perception layer, aside from the sensor technology everyone is familiar with, such as auto ID technology like RFID and barcode, intelligent video analysis can also be used as on-site sensor technology. With the rapid development of semiconductor technology, image analysis in the past that required a large amount of computing power could only rely on PCs. Now, with the DSP developed into an independent intelligent video sensor or embedded directly into a camera, it can collect various on-site information which can not be collected by other sensors.
