Dahua Technology To Release Upgraded IVSS To Explore More AI Functions

March 2021 by Marc Jacob

As the saying goes, “There is always room for improvement.” This year, Dahua Technology is once again utilizing this“room”by releasing the new upgrade of its intelligent server– the Dahua IVSS. The Dahua Intelligent Video Surveillance Server, or simply IVSS, is positioned as a multiple intelligent algorithm server. With its strong computing power and flexibility, it offers multiple algorithm integration as well as innovative, efficient and accurate AI functions.

The Dahua IVSS is equipped with general AI functions that benefit users with optimized monitoring capabilities. Aside from its Face Recognition’s Blocklist Alarm, VIP Recognition and Stranger Alarm, this series now features High Frequency Alarm –a newly added function that can recognize the frequency of targets in the monitored scene. Dahua IVSS devices also support IVS based on target type (human and vehicle), which filters out irrelevant targets such as leaves, animals, lights, etc. With its upgraded algorithm, it provides higher detection accuracy rate, and supports new functions such as Loitering Detection, Parking Detection and Crowd Gathering Estimation.

What’s more, the Video Metadata function of this equipment supports a number of attributes for human face, human body, motor vehicle, and non-motor vehicle. Besides its typical Metadata Search function, the Dahua IVSS can also extract metadata from normal video recordings stored in XVR or NVR devices, and subsequently run AI Search to quickly locate targets. Moreover, this upgraded series now offers Video Metadata Linkage that can trigger the alarm when the target’s metadata does not meet the preset conditions/rules. For example, if wearing face mask is set as a rule, the alarm will be triggered when someone who is not wearing a face mask has been detected. Based on metadata, the Dahua IVSS can also perform backend ANPR, which is a significant upgrade from the frontend ANPR usually done by cameras. In addition to basic AI, industrial AI functions are also featured in Dahua IVSS devices. It includes Smart Video Compression that provides higher computing accuracy and can distinguish specific targets in the scene compared to traditional intelligent algorithms. With compression ratio of 78%-99%*, this AI function significantly reduces bandwidth by up to 99%* and relatively lessens upgrading costs. This series can also detect helmet wearing in a site through its Helmet Detection function, boasting an accuracy rate of over 95%*. Its Outdoor Parking Space Detection function provides over 94%* accuracy rate in detecting available parking spaces in an outdoor scenario. Other industrial AI functions include Fire Detection, Smoking Detection, Uniform Detection, Garbage Overflow Detection, and Animal Detection. Aside from Dahua’s own algorithm, it can also run third-party algorithm through the Dahua Open Platform (DHOP), solving more pain points of customers.

Moreover, the strong and scalable Computing capability of the upgraded Dahua IVSS can utilize up to 16 AI chips. For Storage and Data Security, this series allows access to up to 256 channels, provides up to 768Mbps storage bandwidth, and supports RAID 0, 1, 5, 6, and 10. Its Decoding capacity is up to 24ch@1080P. It offers max. 36 splits in one window, allows up to 4 HDMI output per device with different sources, and supports mouse roaming between different scenes.

Furthermore, the Dahua IVSS allows seamless AI upgrading of old systems, and is compliant with ONVIF/RTSP, making it compatible with third-party cameras. By providing AI computing to VMS through SDK, it also supports integration with third-party VMS.

The biggest room in the world is indeed the room for improvement. Thus, for many years, Dahua Technology has been continuously developing, improving and innovating intelligent products like the Dahua IVSS. In addition to its AI functions, the upgraded Dahua IVSS series also combines video management features with traditional video storage functions in one device, providing robust computing, superior storage, rich applications and strong decoding capabilities. With its mission of “Enabling a safer society and smarter living”, Dahua Technology will continue to focus on “Innovation, Quality and Service” to serve its partners and customers around the world.
