Abstract: How to ensure middle-aged people's security has become an urgent social issue in China. Existing security systems are difficult to initialise with fast electrodes consumption. Therefore, we designed a smart security device suitable for middle-aged and elderly users. We select STM32 and CC2530 as master controller for the device, which is equipped with a camera module, GSM/GPRS module, smoke sensors, flame sensors, and infrared sensors. The camera module is used to capture the live pictures of the monitored areas, then these pictures will be transmitted to the users by the GSM module. Multiple CPU can increase the speed of operation, and ZigBee technology for wireless transmission can lower the loss of the supply. Compared with other security systems, the proposed program optimises the interface to make interaction operation easier for middle-aged and older users. The experimental results show that the proposed system has low power dissipation, convenient operation and high stability.
