In the development trend of digital, networked, high-definition and intelligent video surveillance system, the market demand for network video surveillance system is increasing day by day. With the large-scale involvement of the security industry, especially the comprehensive development of safe city, intelligent transportation and other projects, the monitoring scene tends to be complicated, the monitoring points are dispersed, the application of back-end equipment NVR/XVR is gradually expanded, and the performance requirements are constantly improved.
Recently, Ruixin Micro launched a new security back-end NVR/XVR chip solution RK3568, its four features enable a comprehensive hardware upgrade of NVR/XVR.
1.

Supports a variety of Flash types, including SPI NOR/SPI Nand Flash/Nand Flash/eMMC, and SPI Flash+eMMC dual ROM co-existence design, meeting the requirements of differentiated dual system design
DDR core template and core device selection table that have been tested and verified can be provided to facilitate the rapid production of customers
3.
RK3568 has excellent energy consumption control technology, less heat, strong environmental adaptability
The self-developed S-Boost power consumption control technology of Ruixin Micro improves the performance by 10% at the same voltage and reduces the power consumption by 20% at the same frequency compared with the traditional technology. Combined with the energy consumption advantage of 22nm advanced technology, the heating of security back-end products is more balanced, and the work in high temperature environment is more reliable
In the LPDDR4X application scheme, the power consumption of the whole machine can be reduced to 1.6mA (3.8V power supply) through the cooperation of hardware and software, which is suitable for the products with special requirements for ultra-low power consumption
4.
The RK3568 supports diversified interface expansion and three-screen display, meeting the requirements of diversified security scenarios
With more flexible IOMUX, pin multi-function combination application, can be selected according to product requirements, to meet the needs of more diverse function combination
Supports a variety of video input/output interfaces, the output interface supports its own dot screen, can support up to three different screens; The input interface can be connected to an external camera or used to expand the input capability of multiple cameras. Compared with the traditional NVR/XVR solution, RK3568 adds the local display output interface and camera input interface to realize display integration, which is conducive to the application of different types of security back-end products
Supports two RGMII ports, including PCIE2.1, PCIE3.0, and a maximum of three SATA3.0, two USB2.0, and two USB3.0 ports. PCIE ports enable high-speed throughput applications of 5G and WiFi6 and support services such as carriers and cloud services
RK3568 security back-end NVR/XVR solution, in addition to the traditional access, storage, forwarding, decoding application, based on its high performance AI computing power, but also in face comparison alarm, intelligent vehicle retrieval, cross-border warning, fire visual warning and other aspects of intelligent application, reconstruction of edge value.
Face contrast alarm
RK3568 scheme can support video stream or image stream detection and recognition, by recognizing face attributes such as gender, age, expression and other features, output face real-time comparison.
Intelligent human-vehicle retrieval
Support image search, face search, contrast linkage, second level search, layout control alarm and other functions.
Crossing alarm
RK3568 scheme is based on self-developed efficient RKNN AI processing unit to realize regional intrusion, cross-border detection and other applications, target identification of human body/vehicle, filter all kinds of environmental interference, such as plants, light and shadow, small animals and other false positives caused by non-human body or vehicle.
Visual fire alarm
Based on the powerful core processing capability of RK3568, it supports the security NVR system with temperature rise detection and smoke detection as the core. It can mark the orientation of smoke and fire point and quickly check with video linkage to meet the needs of early fire detection.
At present, the security back-end solution RK3568 has entered mass production. At the same time, two evaluation and development boards based on RK3568 are launched, which are respectively evaluation board for NVR/XVR scenarios and DDR4 evaluation board for industrial control security scenarios, aiming to enable downstream partners to more quickly adapt and verify related product functions, and help the comprehensive hardware upgrade and product landing of the new generation of intelligent security back-end equipment.
