Not just "a camera", but one that's in night-vision mode. The camera may not be using IR, or it may switch to normal mode at any time. You spent too much time telling people off for pointing out this hoody makes your head glow and may draw attention as a consequence.

- double2helix 4y agoAll digital cameras are in "ir mode" point your TV remote at your cell phone camera and press a button on your remote it will light up on your screen.
- sk0g 4y agoNot necessarily for either point, much as I want to avoid being pedantic. My LG CX's remote uses IR for turning on, but beyond that it uses Bluetooth or some similar protocol. Even if a remote is IR, rear cameras are often shielded against it. Front cameras, usually not. This is much easier to notice on IR-powered PC mice of course. Not sure if modern ones use IR as well - haven't checked.
