Remote shielding and short-range shielding, in short, the monitoring shielding is as small as a pen, which can shield all monitoring within 30 meters. The middle distance monitoring is as small as the size of a schoolbag, shielding all monitoring within 500 meters. As long as it appears within 500 meters of the monitoring, the monitoring is invalid, the memory is automatically destroyed, and the ultimate shield appears within 5 kilometers of any monitoring and shooting equipment. All the shooting monitoring equipment failed or exploded, and the computer explosion scared the monitoring camera personnel.
