The invention discloses an integrated vehicle-mounted night photographing module for a law enforcement vehicle and a video recording system thereof. The system comprises the law enforcement vehicle, photographing modules, an audio module, an information processing module, a display module and a wireless communication module. The law enforcement vehicle photographing modules are arranged in a plurality of grooves on four sides of the vehicle body, and each photographing module is provided with an optical element, a short wave infrared camera, a filter wheel, a detector assembly, a photoelectric signal conversion chip and a digital-to-analog conversion chip in sequence from the outer surface of the groove to the inside. Each photographing module further comprises a drive motor for controlling the filter wheel and a high-power tunable laser, wherein the filter wheel carries a filter of which the pass band is 0.9-2.5 microns. The filter wheels are driven by the drive motor connected with a central processing unit to switch imaging bands. The integrated vehicle-mounted night photographing module and the video recording system thereof has important value for development and application of integrated vehicle-mounted video recording systems of law enforcement vehicles.
