SoC is the acronym of System on Chip, it’s the core processor of each IP cameras, DVRs and NVRs. Hence the SoC is the main factor determines the performance of your network CCTV equipment. For IP cameras, the SoC integrates image signal processor (ISP), video codec engine (encoding), digital signal processor (DSP), network peripheral interfaces, intelligent video analysis engine etc all the components.
Unlike personal computers (equipped with Intel or AMD CPUs), users are not able to replace the SoC if planning to upgrade or even repair the system. All IP cameras and standalone DVRs/NVRs use embedded Linux system that stored in NAND flash, updating or upgrading the operating system needs to flash the firmware.
Besides the CMOS image sensor, SoCs become the most expensive component in your CCTV equipment. Today’s top-notch SoC has 4K UHD video encoding and decoding in H.265/H.264 standard capability. No matter we choose the IP cameras or DVRs and NVRs, we need to pay attention to which SoC has been utilized in the hardware design of the device. Generally, a high-end SoC is equivallent to high-end IP security equipment. Many factors determine the performance of the SoC, they are:
As long as we know which the SoC has been used, we are able to do comparison for IP cameras which share the similar features from different brands. However, many IP camera manufacturers don’t disclose the SoC that they use in their products. Amabrella, Hisilicon, Texas Instruments are three prominent and common manufacturers in the IP security SoC field. Well known IP security equipment brands such as Hikvision and Dahua mainly adopt the Ambarella SoC, Uniview and Tiandy uses Hisilicon SoC.
