Home smart camera solution

The home smart camera solution uses Hi3518EV200+LiteOS, and with the MTK7601 low-power WIFI module, it can realize lithium-battery-powered home smart IPC.

In this solution, a human body sensor is used. When a person passes, the sensor is quickly turned on and recorded, and continuous recording is not required, thereby achieving low power consumption.

It can be used for four months on a single charge and can be placed anywhere, without restrictions. With the LiteOS system, 500ms can be booted and recorded after optimization.
