Surveillance camera filtering system and method

The invention belongs to the technical field of electronic surveillance, and relates to a surveillance camera filtering system and method. According to the system and the method disclosed by the invention, a light filter is switched into an infrared light filter in the daytime, and infrared light can be filtered so as to solve the color cast problem caused by the infrared light in the day time; at night, since visible light brings severe interference to a driver at night, a visible light white-light lamp is forbidden to use for snapshotting, the light filter is switched into an all-pass light filter to allow as much light as possible to enter the surveillance camera; meanwhile, the white-light lamp which emits infrared light and ultraviolet light is used, clearer images can be snapshotted since the infrared light and the ultraviolet light have an obvious light filling effect under a condition of dark light at night, and a license number or specific surveillance characteristics can be better extracted.

Process for dispersing hot-melt adhesive fillers

The invention relates to a method for dispersing hot-melt adhesive filler. The method comprises the following steps that: filler and other components of hot-melt adhesive are evenly mixed by granulation equipment; or part of the filler and other components of the hot-melt adhesive are evenly mixed and granulated by granulation equipment, and then the left over filler is evenly mixed with the granulated mixture. Other components of the hot-melt adhesive comprise main body resin, tackifying resin and a diluent agent; the filler comprises toner, flash powder, calcium carbonate, micro silicon powder, talc powder, white carbon black, light white carbon black, metal nitride, metal oxide and metal nitride or metal oxide; moreover, extruding granulation adopts a single screw extruder or a double screw extruder. The method has the advantages that: the addition of a poisonous and harmful dispersing agent is reduced to protect the environment; the filler is evenly mixed through a physical method, and manufacturing technique is simplified to reduce cost; and because a granular material contains less air volatile matter, the product is not easy to generate air bubbles, thereby ensuring product quality.
