Industrial-grade materials, industrial-grade standard design, strict manufacturing process, and wide temperature support enable the device to run stably for a long time even in harsh outdoor high and low-temperature environments; Linux operating system supports watchdog function, which can realize crash reboot and unattended operation, simplifying post-operation and maintenance; dual MIPI interface, to meet the needs of more peripheral expansion. The deep learning instruction set directly handles large-scale neurons and synapses, improving operating efficiency and achieving faster face recognition processing speed.
