Looking at the projector, I think it’s likely that you have TTL modulation which is no-bueno when it comes to crowd scanning beams in your home environment. Converting to analog and adding ILDA capability is certainly possible, but would likely mean dumping all of the auto mode and SD card capability. You would need new diode drivers and some knowledge on how to tune them. After that you would need a DAC and software which allows you to define BAM safety zones and lots of knowledge on how to use such tools safely. Regarding safety scan lenses, I’m not sure you can get that laser to a safe level with even a -6 lens if you are in a small room. Even if you could, you’d need to learn a lot to do so safely.
I think I’d start over by doing a lot of reading and analysis on laser projector offerings and the available software options. This will likely cost a factor of 10 or more as compared with what you have spent to date, so don’t feel bad as you haven’t lost that much money yet. 😁. Like most things, you get what you pay for when it comes to lasers. Feel encouraged to ask lots of questions as you do your research.
Best of luck to you!
