SMD 4.0

Thanks to enhanced AI capabilities, the SMD function filters irrelevant objects from the scene. Equipped with a new deep learning algorithm, SMD 4.0 is optimized to eliminate small and large animals from the scene, thus preventing false alarm triggers.

Quick Pick

Quick Pick technology enables rapid target identification, optimizing the search for relevant SMD events. Thanks to an excellent integration of the intelligent functions of cameras and recorders, this function can search for human and vehicle targets based on an AI algorithm capable of extracting and comparing the colors of clothing and vehicles.

AI SSA

Dahua’s AI Smart Scene Adaptive (SSA) technology is an advanced innovation in the field of surveillance cameras, designed to optimize image quality in various lighting conditions. This technology uses artificial intelligence algorithms to automatically detect and adapt to changes in the monitored scene, ensuring clear and detailed images, regardless of the lighting environment.

AI Encoding (IP Solution)

With the improvement of monitoring resolution, how to maintain image quality while saving storage costs has become one of the most worrying problems for users. Based on CBR (Constant Bit Rate), WizSense AI Coding dynamically allocates the bit rate, providing clear target images while saving a bit rate of over 25% compared to H.265.
