The invention relates to the technical field of image data processing, and discloses an image timestamp marking method, camera equipment and a video monitoring system.The method comprises the steps that exposure time data is determined and stored when an exposure action of an image sensor is detected through a microcontroller; the image signal processor processes the original image data to obtain image data in a specified format; the USB device controller packages the image data into a UVC data packet and sends the UVC data packet to the host device; and the microcontroller responds to a time query instruction sent by the host through the USB control endpoint and returns a response message carrying time data, so that the host associates the time data with the corresponding image data. According to the method, hardware-level time marking is carried out at an image acquisition source, time sequence errors caused by transmission delay in a traditional host end marking scheme are reduced fundamentally, and a reliable technical basis is provided for application scenes with strict time sequence requirements.
