Dahua Technology unveils the wide range of its core products for 2020 that will be instrumental in enabling and accelerating the AIoT transformation. The new product line includes the main over-coax technology advancement HDCVI 6.0, AI (WizSense/WizMind) as well as Full-color technology which enables outstanding performance under extreme low light conditions.
1. HDCVI 6.0
A longtime leader in the realm of HDCVI that offers great convenience, best quality and least cost, Dahua Technology launches HDCVI 6.0, boasting industry’s first 4K real-time and advanced AI capabilities.
4K Real-time
While traditional 4K HD over-coax products only allow 15fps, Dahua Technology’s 4K real-time doubles it, making 30fps a reality in live view. 4K real-time provides a superior visual experience in which tiny details are captured in better clarity within a large monitoring coverage. Moreover, with the help of AI Coding, users won’t have to worry about the storage cost incurred from the clarity enhancement.
AI Coding
Dahua AI Coding takes video compression to a new level of content-awareness. It puts emphasis on human and vehicle 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 efficient handling of videos to save HDD storage cost.
Two-way Talk
In addition, HDCVI 6.0 supports Two-way Talk, which allows real-time communication between camera and recorder with a broadcast-quality audio. A breakthrough innovation 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 actual situation when an incident occurs.
Enhanced AI
Endowed with Enhanced AI (see section 3 below for more information), HDCVI 6.0 is bringing fresh ideas and new possibilities to the industry and will always provide more economical and convenient solutions to customers.
2. Full-color
The demand for cameras to perform in low light environment is on the rise. According to the 2019 IHS video surveillance report regarding global low illumination trend, cameras with advanced low light functionality grows at 20.6% CAGR 2018-2023.
In response to this increasing demand, Dahua Technology developed its Full-color Camera, which captures vivid colorful information even in low-light conditions. In places with high crime rate like a park at night or a dark alley, it effectively extracts the color features of the scenes, such as human, vehicle or other objects, providing great help to police officers during the evidence obtaining procedure.
Dahua Technology provides two series of full-color cameras – LED series and Non IR series – both adopt large aperture lens that collect higher amount of absorbed light and present a more vivid and colorful image under dark environment. These cameras are capable of 24/7 colorful monitoring that can accurately identify people and objects in low light conditions.
Cameras of LED series are equipped with LED that serves as a supplementary light in dark environment. The LED also serves another purpose – to deter intruders – that can significantly reduce crimes.
Cameras of Non IR series have no complementary light device, which will not emit light like infrared camera at night. This means that this type of camera does not interfere with ongoing activities and does not contribute to light pollution in the environment. Also, it prevents reflections in rainy days and attraction of small insects, making it an ideal silent security guard in dim places like stores, parking lots and casinos.
In addition, the full-color camera can work with AI functions to further enhance the probability and accuracy of target recognition and feature extraction.
3. AI (WizSense/WizMind)
To accelerate the AI adoption, Dahua Technology is proud to release WizSense, a series of AI products and complete end-to-end solutions based on deep learning that focus on human and vehicle, providing intelligence, simplicity and inclusivity to users.
WizSense, being easy to use and not pricy to own, is competent enough to meet the needs of most ordinary users. 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 defense against attacks.
Accurate prediction can be realized through SMD Plus, which analyzes human and vehicle shapes based on motion detection that adopts 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 accurate 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 recognizing 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 customized database, more business values can be generated through VIP recognition, Black List alarm, etc.
Moreover, based on intelligent video analysis, 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 with trigger type of human or vehicle will be sent to users, alerting them to verify the situation using video.
After an event, WizSense makes it easy for users to do quick and reliable search based on SMD Plus and Perimeter Protection. Features like face image search and face attribute search can effectively improve the efficiency of target searching. It is worth noting that the data storage is ensured with AI Coding as well, which intelligently saves data space while maintaining the image quality of key targets.
While offering abundant functionalities, WizSense also ensures high-level of cyber security using encryption algorithms that are certified by TÜV Rheinland, UL (Underwriters Laboratories), etc. Users can rest assured that their privacy will be properly protected using WizSense series products.
Furthermore, WizMind is a high-end AI series to be released in Q1 of 2020. While supporting all functions of WizSense, WizMind is also capable of other intelligent functions such as people counting, video structure, ANPR, human face/body privacy protection, large scene monitoring, etc. Designed to create more commercial values for system integrators and installers, WizMind series offers users with end-to-end solutions that can be tailored case by case to satisfy demands of clients.
Application Scenarios
The aforementioned three key technologies work in trinity, resulting in surveillance solutions that can be applied to many situations.
For example, these products are suitable in dark places where theft and other sorts of crimes are likely to occur, such as a dark street corner or a dimly lit bar. They are also useful in places where it is impossible for security guards to accurately remember various features of people and vehicle, such as crossroads, schools, or entrances of residential areas where people and vehicles frequently come and go. They are also applicable to any place where you want to set specific rules, such as vaults of banks or casinos, entrance of a luxury store, or fence of a zoo.
In these situations, Dahua smart solutions serve not only as a sharp eye that diligently monitors 24/7 and clearly records every little colorful details regardless of light condition, but also as a smart guard that can recognize features of each and every people or vehicle in sight. You can create your own black/white list and your guard will treat the visitor accordingly, triggering the alarm, for example, in a spontaneous manner. You can use this guard to verify a visitor’s identity and warn off intruders. If you are looking for a particular person or plate number when collecting evidence, this guard will take care of it. Overall, Dahua smart solutions offers users comprehensive protection as well as personal options to satisfy more diversified needs.
