Dahua introduces three more NVRs to its professional NVR 54-series

Dahua further completes its NVR portfolio by introducing three more series, covering two entry-level models and one high-end model. Professional NVR54-series The 54-series is designed for medium-sized applications that require relatively high demand on storage capacity, such as telecom, electricity, public security, franchised stores and etc. The series has multiple sub-models, including 8-/16-/32-channels, and PoE versions. Here to take NVR5416/5432-16P as an example. The NVR5416/5432-16P supports 16/32 channel with 1080p live view, up to 5Mp & 5Mp cameras, featuring 160Mps for inputs and 128Mps for outputs, which could satisfy smooth recording at HD-megapixel level for multiple cameras at the same time. It max accommodates 4 SATAs, up to 4TB for each. Meanwhile, this series supports maximum 128 online users to operate and manage simultaneously. In addition, the “frame by frame playback” is quite convenient for users to pin the moment as key evidences. This NVR also supports Dahua motorised-lens network cameras to realise auto focus/zoom and other basic functions directly on the NVR, facilitating user’s operation. What worth a special mention is that the NVR is equipped with 16 PoE ports and support IPC UPnP function, which could simplify the installation and configuration. Entry-level NVR31/21H-series Following the big success of previous 31/21 series, Dahua adds enhanced versions of the previous 31/21 edition, targeting on small- and medium-sized applications, such as SOHO, convenience stores and retails. NVR31H-series supports 4-channel@1080p real-time preview and recording while NVR21H-series supports 4-channel@72op. This series adds two-way audio and alarm functions as well as remote control. What’s more, it enjoys two “L” — low consumption and low noise, keeping “environment-friendly” guideline in design and production. All Dahua NVRs conform to ONVIF protocol and support a wide range of third party cameras.

Dahua elaborates on application of H.265 compression standard
Dahua elaborates on application of H.265 compression standard

Driven by ever growing demand for high definition and the development of image processing, 4K is definitely a buzz word on the market, playing an increasingly vital role in video surveillance, especially in applications such as safe city, parking lot, harbour, plaza and elsewhere large scaled and has strong demand on detail capturing, which, at the same time, pressuring on decoding and storage. Luckily, we see a future there with the introduction and development of H.265, which brings extensive possibilities and optimism to the industry by addressing problems such as shortage of bandwidth, improving transmission efficiency and delivering other benefits. Benefits of H.265 High Efficiency Video Coding (HEVC), also known as H.265, is a proposed video compression standard, a successor to H.264/MPEG-4 AVC (Advanced Video Coding), currently under joint development by the ISO/IEC Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG). Compared to the current mainstream AVC standard H.264, H.265 is said to be capable of further reducing by 50% the data rate requested for high quality video coding. Bitrate is acclaimed to have around 40% to 50% down at 1080p while rendering superb image quality. Put it in summary, first, H.265 can downsize video footage to a great extent while playing fairly smooth video with low bandwidth, and all these benefits further drives market demand on 4K/Ultra HD; second, with the fast development of 4G and mobile technology, the integration between the two industries will have much more amazing possibilities. Dahua’s H.265 product line-up Despite all the benefits, the current phase seems a little bit embarrassed for H.265 as this compression standard is still new to video surveillance industry, which means it will take some time to be adopted and adapted. Dahua Technology, as a leading and innovative corporate, can’t resist its charm and prospect, have the blue picture not only just in mind, but also bring it to reality already. The company has adopted H.265 in its latest product portfolio, including network camera, NVRs, transmission devices as well as video-wall systems. To start with cameras, Dahua has a latest-released 5.0-Megapixel ultra-smart network camera that uses H.265/H.264 dual codec, allowing over 40% lesser bandwidth use while acquiring outstanding image quality. Moreover, with its functions such as ultra-defog, RoI, and intelligent detections, the camera can make surveillance clearer, smarter and smoother; based on this trend, we can foresee more H.265 cameras in different resolution are on its way. When it comes to back-end devices, Dahua was the first in industry to introduce a comprehensive H.265 4K NVR product lineup, which covers various demands, including small-to-medium as well as large-scaled applications. These NVRs are up to 12.0-Megapixel decoding capability, supporting 1080P@60fps and H.265 preview & playback; 4 channel 4K real-time live view & playback; meanwhile, its intelligence functions including behavioural analysis, facial detection and etc. are also supported. What worth mentioning is that the R&D team put energy consumption into consideration at planning phase to make the product eco-friendly. In addition, Dahua also introduced a control platform M70 with H.265 standard, the platform can decode multiple channels of H.265 videos at the same time; and thanks to modular design, M70 can maximise to handle up to 40-channel UHD video outputs with each supporting H.265 decoding; what’s more, these HD output videos can be presented as an integrated image by combining HD outputs. H.265 brings more possibilities “Obviously, H.265 is one of the major compression standard that allow us to implement UHD solutions, such as 4K or even 8K, which is definitely the trend of video surveillance.” said James Wang, Product Director of Dahua Technology. “The benefits H.265 brings are not limited to the above,” Wang continued, “just like a magician hat, you can expect much more from it, for example, our R&D has carried out some great performances on bitrate control, image quality balance as well as intelligent analytics and tracking.” “For me, I always feel thrilled towards new things and technologies as they have the potential to nourish many new possibilities, to bring products, industry, even the society to a better shape,” Wang added. “H.265 is just the case, we have confidence to tap out of the potential of this standard and make full use of it, so my advice is stay with us, stay with the latest trend and see how we use it as a magic.”
