I also don't see why it wouldn't work on AP2.5 or 3. The camera assembly itself has the same form factor and you are tapping the rear view mirror for power, which also has not changed.
I'm not sure if it's of any use to people here but I have developed a tool to download the recordings from the IRO (ddpai) dashcam for the AP1 automatically to a PC. The tool is a python script and checks every 10 minutes for new recordings to appear over wifi. It then compares thumbnails to understand the periods when the vehicle is in use, downloads the relevant files and then joins them together into one video per journey. The main requirements are a camera running 24x7, a good enough wifi signal to the device and a computer to run it on (docker being the easiest approach). The camera runs in AP wifi mode so some kind of wifi bridge / interface is required to get that connectivity.
