Meet Eileen 3, member of the SeeCube small thermal camera core family
The EILEEN 3 is a highly versatile and cost-effective LWIR camera core built by Senssight, expertly engineered for integration into space-constrained embedded systems. Based on the proven SeeCube family and FullScale hardware, this camera delivers market-leading performance in terms of size, power, and image quality. It provides sharp, precise thermal imagery using QVGA resolution (320×240 pixels) and is notably the first thermal camera core in Senssight’s portfolio. With an ultra-small form factor and an ultra-lightweight build of just 15g, its design is optimized for applications where physical constraints are extreme. A key capability of the EILEEN 3 is its support for native shutterless operation (with an optional factory-calibrated enhancement), ensuring continuous, uninterrupted imaging, alongside an optional thermographic mode for temperature measurement. This combination of low cost, small size, and high-quality imaging makes EILEEN 3 an ideal choice for streamlining various thermal vision solutions.
