Jamming devices can be used to interfere with surveillance cameras by emitting signals on the same frequencies that the cameras operate on. These signals disrupt the communication between the camera and the monitoring system, causing the camera to either malfunction or display distorted footage. By continuously emitting strong signals, jamming devices can effectively block the transmission of video data and prevent the surveillance cameras from capturing clear images. Additionally, advanced jamming devices are capable of targeting specific frequencies used by different types of surveillance cameras, making it even more difficult for the cameras to function properly. Overall, using jamming devices can be a relatively simple yet effective method to interfere with surveillance cameras and compromise security monitoring systems.
