Aiming at the risks that may be encountered in the process of equipment transportation, the photoelectric detectability of four types of consumer-grade surveillance equipment that commonly available in the market (MB, DC, DSLR and DV) was analyzed and achieved effective jamming to each device in combination with transportation safety requirements. By building a cat-eye laser detection system, laser jamming system and echo signal receiving system, it focused on the breakthrough of the theories and key technologies such as detection and identification of typical small-caliber surveillance equipment, and bidirectional imaging between cat-eye detection device and target. On this basis, the detection and imaging jamming effect of the visible-light band laser on cat-eye target under different distances, jamming wavelengths and apertures were analyzed, and an evaluation standard of image jamming effect as well as the effective jamming threshold of different optical surveillance devices were proposed. The experimental results show that the typical optical surveillance device has good photoelectric detectability in the experimental distance and can be jammed effectively. When the laser beam completely covered the aperture of the lens, the closer the distance between the target and the device, the smaller the divergence angle of the laser beam, the closer the waveband to the maximum waveband of the human eye sensitivity (555 nm), and the better the non-harmful imaging jamming effect generated by the laser beam.
