during the day my cameras are extremely clear, when vehicles pass by the video is perfect. the problem i have is during the night, in IR mode or color mode, vehicles, people walking, basically moving items look extremely unclear. example is a kid was riding one of those hoverboards and he basically looked like a ghost rolling down the street. when a car goes by it is just streaks of light, and you can barely make out the type of vehicle it is. i don't understand how during the daytime they work perfect but not at night.
i have a kantech 3TB dvr
and Illustra 610 HD outdoor dome cameras
any help would be appreciated, thanks.
