=='''Product overview'''==
V831 is a high-performance, low-power IP camera SoC for the video encoding industry. It can be widely used in security monitoring, SDV, driving recorders, police wearable cameras and other fields. V831 integrates a single-core ARM Cortex-A7 and supports a frequency of 800MHz. Comprehensive H/H. 265 video encoding supports multi-stream encoding, and the performance of H.265 video encoding can reach 1080p@30fps. V831 integrates the latest technology to generate image correction algorithms such as ISP image processor, NPU, EISE, wide-angle distortion correction fisheye and PTZ correction to achieve professional image effects. In order to reduce BOM cost, V831 embeds a 64MB DDR2 chip. V831 adopts advanced low-power technology and low-power architecture design, which greatly reduces BOM cost. Allwinner SDK has high stability and ease of use, supporting rapid mass production.
