Dahua Technology unveiled its 2020 core products in Intersec Dubai, enabling and accelerating its AIoT transformation. The launch included its coax cabling technology advancement, HDCVI 6.0, AI (WizSense/WizMind), as well as full-colour technology which enables better performance under extreme low-light conditions.
HDCVI 6.0 offers 4K real-time and advanced AI capabilities. While traditional 4K HD-over-coax products only allow 15 fps (frames per second), Dahua’s 4K real-time doubles it, making 30 fps a reality in live view. Moreover, with the help of AI Coding, users won’t have to worry about the storage cost incurred from the clarity enhancement.
Dahua’s AI Coding takes video compression to a new level of content-awareness. It puts the emphasis on humans and vehicles while encoding, significantly improving the streaming quality compared with H.265. At the same time, AI Coding also reduces the bit rate when there is no real target in sight, allowing for efficient storage costs.
In addition, HDCVI 6.0 supports Two-way Talk, which allows real-time communication between camera and recorder with broadcast-quality audio. A breakthrough in audio-over-coax technology, the Two-way Talk feature does not just satisfy users’ demand for auxiliary audio information, it also enables bi-directional audio intercom that can be used to warn off intruders and to verify the situation when an incident occurs.
Dahua has also developed its full-colour camera, which captures vivid colour information even in low-light conditions. The company offers two series of full-colour cameras – LED series and Non-IR series – both adopt large aperture lenses that collect higher amounts of absorbed light and present more vivid, colour images in dark environments.
AI (WizSense/WizMind)
To accelerate AI adoption, Dahua has released WizSense, a series of AI products and end-to-end solutions based on deep learning that focus on humans and vehicles. Its benefits include: accurate prediction before an event, instant deterrence during an event, quick target search after an event, storage saving while ensuring target details and privacy protection and defence against attacks.
Accurate prediction can be realised through SMD Plus, which analyses human and vehicle shapes based on motion detection through a deep-learning algorithm. It effectively filters out false alarms triggered by raindrops, leaves, pets, insects and light, allowing users to focus on real threats.
WizSense also supports perimeter protection, which functions in a similar way as SMD Plus in terms of its prediction capability. It allows users to set more flexible rules for different scenarios. While SMD Plus applies to the whole scene by default, perimeter protection could be applied to a specific area, especially where the direction of the movement needs to be detected.
Aside from recognising whether the target is a person or a vehicle, WizSense is also equipped with face detection and face recognition features to aid further identification of targets. By comparing face images with those recorded in the customised database, more business values can be generated through VIP recognition, black list alarms etc.
WizSense also provides instant deterrence functions. When intrusion has been detected, these features will enable the camera to flash and make alarm sound to warn off intruders and avoid possible crime. At the same time, real-time push notifications will trigger a response, alerting officers and verifying the situation using video.
WizSense also ensures a high-level of cybersecurity using encryption algorithms that are certified by TÜV Rheinland, UL (Underwriters Laboratories) and more.
To be released in Q1 of 2020, WizMind is also capable of other intelligent functions such as people counting, video structure, ANPR, human face/body privacy protection, large scene monitoring, etc.
