The report from Electronic Enthusiasts indicates that security IPC chips are evolving towards higher definition, greater intelligence, and more integration. On one hand, with the popularity of ultra-high-definition video and artificial intelligence technologies, IPC chips need to support video encoding and decoding at 4K or even 8K resolution, as well as perform complex AI analysis (such as facial recognition and behavior detection) at the front end, which raises higher demands for chip computing power and energy efficiency. To meet these requirements, manufacturers are integrating dedicated NPUs or AI accelerators into their chips and adopting advanced processes to reduce power consumption.On the other hand, to lower system costs and complexity, IPC chips are integrating more functional modules, such as highly integrating ISP, video encoding, network interfaces, and security encryption into a single SoC. Some leading chips also support multi-camera input, 3D ToF depth sensing, Wi-Fi/Bluetooth wireless connectivity, etc., to meet the diverse visual application needs of the IoT era.Recently, Guoke Microelectronics officially launched the new generation of lightweight multi-lens IPC (network camera) chip – GK7203V1 series, which is positioned for consumer-grade and IoT edge visual applications, providing a highly integrated and low-cost solution.The GK7203V1 series adopts an ARM Cortex-A7 + RISC-V dual-core architecture, integrates a 0.2TOPS general-purpose NPU, supports STR (low-power standby) mode, and has built-in 64MB/128MB DDR with DDR self-refresh, effectively reducing power consumption. In terms of video processing, the GK7203V1 series supports H.264 encoding and 1296P@30fps high-definition video processing, while integrating a rich set of peripheral interfaces, including RTC, POR, USB2.0, SDIO, SPI, UART, I2C, etc., as well as various display interfaces such as RGB/I80 parallel, SPI serial, BT.656/BT.1120, with a maximum output resolution of up to 1280×720@60fps.To meet the low power consumption requirements of battery-powered devices, the GK7203V1 series has three major advantages in its design: first, ultra-low standby power consumption, supporting STR deep standby mode, in AOV (Always-On Video) mode, the power consumption for a 2-megapixel @1fps ultra-low frame rate scene can be as low as about 40mW, combined with the NPU to achieve rapid and accurate target detection, reducing frequent activations and power loss caused by false triggers; second, high-precision fill light control, synchronizing AOV image capture with fill light to further reduce battery device energy consumption and extend battery life; third, fast start acceleration design, with a built-in MCU module combined with a fast-start Linux system, significantly shortening the time to output the first stable image, enhancing the user experience for immediate use.The GK7203V1 series also supports multi-lens camera access, allowing dual cameras to be connected via MIPI interface and expanded to a maximum of 4-lens input, supporting mixed input modes of MIPI and DVP, compatible with image sensors of different resolutions, meeting application needs such as multi-camera monitoring, gun-ball linkage, long and short focus combination, and multi-angle monitoring. Based on the 0.2TOPS NPU computing power platform, this series provides an open toolchain to support customers in deploying customized AI algorithms and has freely opened over 30 commonly used intelligent algorithm licenses, covering core scenarios such as facial recognition, target detection, and behavior analysis, significantly lowering the threshold for small and medium enterprises to develop intelligent cameras. With features such as low power consumption, multi-lens imaging, open NPU, and a wealth of free algorithms, the GK7203V1 series is regarded as the core engine for cost reduction and efficiency improvement in the consumer-grade IPC market, suitable for diverse edge visual applications such as battery cameras, dash cams, video doorbells, drone transmission, scanners, and facial recognition terminals.The IPC market is becoming increasingly competitive with the listing of Starry Technology and the return of HiSilicon. In addition to Guoke Microelectronics, Broadcom Integrated has recently launched new IPC chip products, including BK7259, BK7239N, and BK7236N.Among them, BK7259 is a highly integrated 1×1 single-band 2.4GHz Wi-Fi6 and BLE5.4 chip, with an ARM Ethos-U65 microNPU and Cortex-M52 MCU built-in, a maximum frequency of 1GHz, equipped with audio ADC/DAC, ISP, H264 encoding and decoding, etc., supporting a resolution of 2560×1440, applicable to visual screens, IP video intercoms, AoV IP cameras, HMI applications, and other IoT products.
