Abstract
Systems and methods in accordance with the present disclosure relate to an image capture device to perform computer vision-based tamper detection of the image capture device. A system can use a light source, such as an infrared LED, to illuminate an image captured by the image capture device, which can be used to validate error conditions, such as tamper events. For example, the LED-illuminated image can be compared with an image captured while the LED is off to distinguish tamper events or other error condition events from false positives. The tamper detection can be performed to filter initial error detections, such as error detections performed using edge detection or other computer vision operations, that may be susceptible to false positives.
