The video signal output by the automatic gain control camera must reach the standard level specified by the TV transmission, that is, in order to be able to output a standard video signal under different scene illumination conditions, the gain of the amplifier must be able to be carried out in a larger range Adjust. This gain adjustment is usually done automatically by detecting the average level of the video signal. The circuit that implements this function is called an automatic gain control circuit, or AGC circuit for short. The sensitivity of the camera with AGC function will be improved at low illumination, but the noise at this time will also be more obvious. This is because the signal and noise are amplified simultaneously.
Insecticides are pesticides that are formulated to kill, harm, repel or mitigate one or more species of insect. Insecticides work in different ways. Some insecticides disrupt the nervous system, whereas others may damage their exoskeletons, repel them or control them by some other means. They can also be packaged in various formsincluding sprays, dusts, gels, and baits. Because of these factors, each Insecticide can pose a different level of risk to non-target insects,people, pets and the environment.
