Are there even IP cameras manufactured domestically to even choose? I have some inside my home (pointed at exterior doors; not inside bedrooms which seems borderline creepy and/or sadistic), but they're not connected to public networks and thus I don't consider them a risk.
There are companies that make security hardware here in the US, but the market is mostly very high-end government and military customers. And TBH mostly they are still using Chinese components, just assembling stuff here in the US and marking the price up enough that they can justify calling it 'made in USA' by virtue of the value-add. Sometimes the software is coded or at least audited, though.
You can avoid the worst Chinese-made hardware if you look for "NDAA compliant" rather than US domestic manufacture. NDAA compliance means that a product isn't made by a number of prohibited Chinese suppliers who are known to be very thoroughly compromised (as opposed to the average level of compromise that you should assume most companies in China have... but China is a big place, so that difference isn't nothing).
Axis and Bosch both have NDAA-compliant product lines.
I was giving an analogy. You won't risk installing any camera near to your kids, so is similar is the risk of handing mobile phone with a camera, which is capable of spying them/software that modulate them all the time!
Blue Whale was an example which forced people to commit suicide.
In TikTok's case the probability of immoral use is the most. As its has a connection with CCP, or is obliged to co-operate if required with CCP. Not juts USA, many countries had its suspecision with this APP. Ignoring all that why would any one wanted to risk there kids with this one specific APP ?
