A quick search for "IR cut security camera" on Amazon returns hundreds of results. Some cost as little as $20 [1], so not uncommon at all from what I can tell.
> Even for those that do, IR filters are rarely perfect, so a bright enough IR light would still do the trick.
Do you have a source for this? I've never tested it, so I can't say, but I would want to want to see some proof first.

That's the very opposite. That's a camera that uses IR illumination to record at night. That's what all those LEDs around the lens are for. And due to this it lacks any IR filtering. This particular camera is more IR sensitive than most cameras like DSLRs or cell phones.

You can test it by pointing a remote at a camera. Normal cameras like cell phones and DSLRs have IR filters. They still can see the blinking LED on an IR remote, because the filter isn't perfect.
