WizSense, which was introduced to the market by Dahua Technology, is a series of a wide range of products and solutions based on artificial intelligence (AI), using an independent AI chip and deep learning algorithms. This technology allows for accurate recognition of people and vehicles in an image, allowing users to focus on real goals.
SMD 4.0
Thanks to advanced artificial intelligence capabilities, SMD 4.0 (Smart Motion Detection) feature filters out irrelevant objects in the scene. Equipped with a new deep learning algorithm, this technology is optimized to ignore both small and large animals, eliminating false alarms.
Quick selection
Technology Quick selection allows you to quickly recognize interesting targets - people or vehicles - which significantly improves the search for events recorded by SMD. Thanks to the perfect integration of the smart camera and recorder functions, this function allows you to search for targets (people/vehicles) based on an artificial intelligence algorithm that analyzes and compares, among other things: the color of clothing or vehicles.
AI SSA (Scene Self-Adaptation)
AI SSA The technology, based on a deep learning algorithm, can intelligently recognize different scenes and automatically adjust image parameters to obtain their optimal rendering.
Artificial Intelligence Coding (for IP solutions)
As monitoring resolution increases, maintaining high image quality while reducing data storage costs has become a key challenge. WizSense AI Coding The technology, based on constant bit rate (CBR), dynamically allocates the bit rate, ensuring a clear target image while saving more than 25 % of bandwidth compared to the H.265 codec.
