Re: Enhance the effect by adding IR LEDs!
Same AC, that is how I would test remotes also, but for years now, on every device I have used doesn't show IR, the only thing that I have bought recently that does are 2 cctv cameras, they were cheap from china, they see IR, but need to because of they using that for its 'night vision'.
The last compact camera I bought years ago (over 10) Canon ixus 250 has an IR filter. Nor does IR show up on my mobile. Webcam on the computer logitech c525 has an IR filter.
