1. System introduction
The low-power battery camera works in tandem with two chips, Camera SoC and WiFi SoC.
The Camera subsystem mainly implements camera quick startup and media collection-related functions such as video and audio collection and encoding, video and audio storage and transmission, video analysis, and alarm push, and quickly enters the power-off standby state after the relevant business functions are completed.
The WiFi subsystem not only provides the network transmission function, but also provides functions such as power management, Pir management, standby keep alive and remote wake-up of the Camera subsystem.
2. Hardware framework
The low-power battery camera is realized by Camera SoC and WiFi SoC. The overall hardware framework is shown in the figure below.
3. System running status
The system has three operating states, which are distribution network state, standby state, and wake-up state.
3.1. distribution network status
After starting up for the first time or restoring the factory settings, it is in the network configuration state. In this state, the user can complete the WiFi network configuration by pressing the prompt tone operation. After the network configuration, the system parameter setting and video browsing can be performed.
3.2. Standby state
After the network distribution is completed, the system will enter the standby state. In the standby state, only the WiFi subsystem is running, and running in the low power consumption mode, other modules are powered off and do not run, and at the same time maintain the necessary connection with the server, which is used to receive the wake-up command sent by the mobile phone APP through the server and output the wake-up signal to the power supply Module and Camera subsystem. The WiFi subsystem periodically sends heartbeat packets to the server to maintain the connection with the server when the battery camera is in standby.
3.3. Wake-up state
When the device is in standby mode, there are two ways to wake up the device, which are Pir wakeup, phone APP wakeup and power button wakeup.
The Pir module is connected to the WiFi subsystem. When the Pir function is turned on, when a heat source such as a person or an animal passes by, the Pir will trigger a wake-up signal to the WiFi subsystem, and the WiFi subsystem will output a wake-up signal to the power module and Camera subsystem, so that the entire When the system is running, it pushes alarm information, snapshots and videos, etc. After Pir wakes up the device, it works for 15 seconds and then enters the standby state again.
Mobile APP users can wake up the camera and view real-time video, playback video and set parameters at any time as needed.
4. Product extension
Low-power battery camera products can also be further extended to low-power battery doorbells, low-power 4G battery cameras and other products.
