The patented Witness IOT camera is solar-powered and includes a specially designed CMOS image sensor consuming less than 700uW.
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, a world first.
“Enabling a range of applications from unattended surveillance and camera traps to wildlife observation, Witness perfectly embodies CSEM’s technological strategy,” said Alain-Serge Porret, VP Integrated and Wireless Systems at the Swiss Research and Technology Organization. “We aim to deliver autonomous, low-energy-consuming devices combining both intelligence and efficiency.” Forthcoming versions will thus include VGA resolution as well as embedded face recognition.
The Witness 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. An innovative high-dynamic range (120dB) CMOS image sensor consuming less than 700uW @ 10 fps for 320x320 pixels was designed; 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.
