What do you mean actual jammer? If it puts out RF at a power level greater than the surrounding environment it is a jammer, correct? I would think for this attack to work you could just target the camera freqs used, you don’t have to target the whole home’s WiFi network. Probably a narrower range to focus on.

I don’t think it’s that simple. The newer Wi-Fi standards are broadband, so the required power spectral density to block Wi-Fi across all channels is pretty extreme. I don’t think you’re doing that for $40. We should also keep in mind the standards were designed to operate in environments with other unlicensed devices and in the presence of interference.
If you just want to target the frequencies the cameras are using, that would require a little bit of research skill but I think would allude most criminals. Also, some routers will change frequencies if the interference is bad.

WiFi 6 camera probably exist, but most will have WiFi 5 or lower. Theres only 13 channels and of those usually only 3 or ever used due to band overlap.

Good point! I forget these devices are rather cheap.

Lol. None of my smart devices will connect to anything other than a 2.5ghz connection. Only my TV will accept 5g. The range is MUCH narrower than you think. Then figure in that the top 5 or 6 companies provide hardware for 90% of peoples home installations and that pool becomes even smaller. Also, a microwave operates on the same frequency as 2.5 and was a common disconnection problem in the past.
This is trivially easy.

I’m down to two 2.4GHz devices over the whole network now.
The day I can disable it entirely will be a happy one!
