The growing need for security and surveillance offers opportunities for low-cost autonomous IOT cameras. CSEM has leveraged its unique experience in the design and development of ultra-low-power microsystems to develop a fully autonomous portable camera that can be deployed quickly and easily via an adhesive patch or magnet.
The IoT camera consumes less than 1mW of power in active mode, fully covered by a flexible, high-efficiency photovoltaic cell with an adhesive surface. Suitable for indoor or outdoor use, it is the fruit of years of research and development into the key enabling technologies. The researchers designed an innovative high-dynamic range (120dB) CMOS image sensor consuming less than 700uW at 10 fps for 320x320 pixels; intelligent embedded software allows triggering by scene–activity detection. The camera records fixed images at 1fps and stores them in flash memory for later USB readout. Witness prototype measures 80x80mm. The camera button is 30mm in diameter and only 4mm thick. Forthcoming versions will thus include VGA resolution as well as embedded face recognition.
