Any laser aimed into the camera's lens or even hitting its dome causes drastic shifts in exposure, at least, and completely washed out or colored video at most. However, while substantially damaging a camera is hard, temporarily "blinding" it/obscuring subject was easy. Striking or shooting a camera is far more likely to damage a camera than using a laser. Attaching the laser to a stationary object for aiming makes sensor damage much more likely. Aiming by hand difficult: Targeting a laser towards a camera is difficult from more than ~10' away.Close range required: Permanent damage did not occur from distance of ~50 feet or further from the camera, regardless of the strength of the laser we tested.Our testing showed it is difficult to permanently damage surveillance cameras because: This video overviews how we tested and what we found: Warning: This report has fast flashing lights that may cause discomfort or trigger seizures for those with photosensitive epilepsy. IPVM bought and tested lasers on surveillance cameras to determine what impact they have: Hong Kong protests have brought global attention to video surveillance and the ongoing attempts of protesters to disable or undermine those cameras using lasers.
