So I had researched it a while ago and don’t recall having found anything effective and non-suspicious to protect from public camera mass survaillence in cities and the like. Is there anything that is a good option for that yet, and if so, could you point me toward it?
Handheld scanning infrared laser, 5 to 50 watts Basically laser-clean the sensor out of existence

electronics and industrial supply places, you can rip it off a diode based laser cutter but they’re very chonk, if you’re handy, you’d get just the diodes, lens and then make your own PCB with powersupply. You need adjustable because the light has to be in focus at the distance between you and the camera or else it will be to diffuse to disable the sensor, both too short and too far. You don’t really need a galvo head in this case just mount the pcb on something that can randomnly vibrate the laser in a small radius at the effective distance. You won’t be able to hit the camera sensor steady, you need to paint over it randomnly, with the right focus it will work even on rare occasionnal hits since those sensor are very sensitive to laser light
In the past, individuals have cut down red light and speed cameras using power saws. Are you suggesting a laser would be easier to just burn the pixels of the camera? Wouldn’t that be dangerous for people around you?
Yes, it is dangerous even the reflections off the camera could be dangerous. This requires the same awareness of others as handling a laser cleaner.
Here is an article about using a pulse laser to blind a camera sensor
