I need the V3 CAM RTSP Firmware asap for school

Hello everyone, I am a student in my third year of college. My School project is a robot being built by myself. I already purchased the V3 cams and I am past being able to return them. They are being used for recording and documenting the project and the video stream is used for robotic vision , aka object detection. I really need the firmware file to make the cams I already have work. I really appreciate any ones help. I realize that the firmware was removed from the website, but I already bought the cameras, so i would like to use them.
