do you have examples of cameras or smartphone which do not have IR filters?
- Ballas 2y agoI don't but it's easy to test, just pick up a TV remote and press a button while pointing it towards the camera. It should look like a flashing white LED. I should also mention that both IR illuminators and TV remotes are usually either 850nm or 940nm, I have not looked into that aspect of it. I imagine that it's possible that your camera can detect one but not the other...
- ddingus 2y agoMy phone goes up to 980nm and it is a Note 9. Both front and rear cameras work. The light shows up as a pinkish purple.
- botanical76 2y agoThanks, I had no idea about this. My Google Pixel 8a doesn't show anything on either camera, but my friend's front camera did! It shows up light purple.
- karlkloss 2y agoRaspberry Pi sells a camera especially without IR filter.
- amatecha 2y agoFor anyone curious, that would be the "NoIR" camera: https://www.raspberrypi.com/products/pi-noir-camera-v2/ https://www.raspberrypi.com/products/pi-noir-camera-v2/
- lightedman 2y agoEasy test - check your black levels against someone wearing a black fabric or a reflective black surface. If you get a fair bit of grey in the image, odds are very great that you don't have an IR filter installed.
