Relatively low resolution with a wide FOV. I think these devices are being aimed at presence detection and other applications that do not require great resolution, but benefit from having more pixels than a common PIR sensor. It is good to see such devices being developed as we will see more advanced thermal monitoring systems. The FLIR AX-8 thermal monitoring camera is only 80 x 60 pixels, uses a Lepton core and is really expensive ! Such cameras are widely used in industrial applications as an early warning system for mechanical overheating, such as motors and bearings.
