NViS 5704: A Powerful 1U Rackmount NVR for Video Stream Analysis, Driven by 13th Gen Intel® Core-i Processor

Backgrournd

In the realm of 1U Rackmount Network Video Recorders (NVRs), consumers are expressing interest in advanced streaming analysis once the system can support PoE switch for network cameras. This has prompted system developers to explore the viability of augmenting the video streaming processing capability. Users anticipate a highly computing and scalable system that can seamlessly incorporate AI inference accelerators or graphics cards to enhance the system's performance in video streaming and analysis spontaneously. These enhancements could be particularly beneficial for tasks like motion detection, object detection, face recognition, and other prevalent applications within the domain of multi-person re-identification, all of which are commonly employed in video surveillance systems.

In the present landscape, deep learning has become a standard feature in NVRs. Deploying model inference in NVR trained by CNN, RBFN, MLP, DBN and more is off-the-shelf function. Consequently, the task of selecting the appropriate, accurate, and real-time accelerator solution for gradual integration into the system has evolved into a crucial requirement within the surveillance market.

Challenge

Currently, a significant portion of the existing 1U Rackmount NVR market utilizes motherboards smaller than Micro ATX for incorporating supplementary PCIe cards. This choice is driven by the constraints posed by the inability to accommodate full-height and full-length cards. Moreover, the board's dimensions prevent the simultaneous inclusion of M.2 Key B and M.2 Key M interfaces. Complicating matters further, older Intel® platform CPUs can solely support PCIe x16 interface output. Consequently, enabling support for M.2 Key M PCIe 4.0 x4 necessitates a reduction in the specification of the PCIe slot to PCIe x8. This situation imposes limitations on the addition of a graphics card.

Solution

Thanks to the significant enhancements in Intel®'s 13th Gen design, there has been a marked improvement in the CPU PCIe pipeline. This advancement includes a combination of PCIe 5.0 x16 and PCIe 4.0 x4 interfaces. This innovation allows for the inclusion of a PCIe 5.0 x16 slot for adding accelerator cards, along with an additional NVMe support slot (Intel® 13th CPU PCIe pipeline is presented in Table I). This technological leap also enhances NVMe performance by enabling PCIe 4.0 x4 support (The performance test result between PCIe 3.0 x4 and PCIe 4.0 x4 are presented in Table II). With this upgrade, NViS5704 no longer utilizes standard Micro ATX form factor design, which now enables it to be equipped with a PCIe slot supporting both PCIe 5.0 x16 and M.2 Key M PCIe 4.0 x4 configurations. Consequently, users have a broader range of options to choose from, catering to their specific requirements.

With the inclusion of an additional PCIe 4.0 x4 interface, users have the capability to integrate accelerator cards like the Hailo-8 M.2 interface module. This facilitates the seamless adoption of various Hailo-8 modules, effectively boosting video streaming inference performance. Such require compatibility with higher specifications of the PCIe 4.0 x4 speed specification. On the other hand, if the PCIe pipeline specification fails to meet the requirements of accelerator cards, it could result in a significant reduction in inference performance. (Hailo-8 performance test result between PCIe 3.0 x4 and PCIe 4.0 x4 are presented in Table III).
