Recording method and device by using low-power-consumption recording system

A recording method using a low-power-consumption recording system, comprising:

• configuring an operation mode of the low-power-consumption recording system, wherein the operation mode comprises a first-stage operation mode, a second-stage operation mode, and a third-stage operation mode;
• switching to a current operation mode based on a trigger condition of each operation mode;
• and
• scheduling power-on/off processing logic of hardware units comprising at least one of:
• a real-time clock, double data rate memory, a microcontroller unit, a storage unit, a control photosensitive device, and a camera in the low-power-consumption recording system based on the current operation mode, to perform video recording,
• wherein the configuring of the operation mode of the low-power-consumption recording system further comprises:
• configuring the first-stage operation mode of the low-power-consumption recording system, to perform timed recording activation in the first-stage operation mode;
• configuring the second-stage operation mode of the low-power-consumption recording system, to start a minimized shooting unit by using an alarm in the second-stage operation mode, to implement photo shooting;
• and
• configuring the third-stage operation mode of the low-power-consumption recording system, to start all devices, units, and modules in the system in the third-stage operation mode, to perform continuous video recording.
