SMD 4.0

What is SMD?

In 2018, Dahua Technology innovated the Smart Motion Detection (SMD) Technology to differentiate human and vehicular shapes within a scene and send alarms to secure your business and family.
The use of SMD is closely integrated with the scene, and the scene itself often requires diversification. Therefore, as the application of SMD in the industry continues to deepen, the demands of users for SMD applications will become more and more diverse according to different scenarios.Dahua has been continuously addressing the requirements of various application scenarios by dedicating its efforts to the optimization and innovation of SMD.
