Visual motion detection is one of the most active areas in systems neuroscience today 1,2, and the cellular mechanisms of directional selectivity may soon be understood in unprecedented ...

When intruders enter the field of view of the two PIR sensors, the detector analyzes the body's thermal radiation with correlation and spectral analysis to filter false alarms, making sure that it is ...

Just as motion detection needs to be reliable ... so you might not get crisp images like this in every motion sensor camera.
