Even more clearcut, all the cameras in all the neighbouring flats get disabled (this is actually the reason why jamming is illegal -- EM radiation doesn't know to respect property boundaries).

It looks like the script uses arp-scan to detect cameras. That is an ethernet-level tool so it will detect only devices on the wifi network your computer is connected to, not all networks within range.

Yep, you're right. An 802.11 client broadcasts the MAC address in every frame in plaintext, so a more straightforward approach would be to use `airodump-ng` to list the cams. The innocent bystander practical & legal concerns were probably the reason author did it this way.

This particular script is not really a jammer in the traditional sense. It's simply a de-auth command to a specific device on a specific network. So with a little care you could ensure you were only dropping the indoor cameras.

The FCC considers sending deauth packets "jamming" according to https://apps.fcc.gov/edocs_public/attachmatch/DA-15-113A1.pd...

Its more subtle than that.

The FCC considers sending deauth packets to networks you are not supposed to be in control of jamming.

So, still a bad thing here, but not quite the same reason.

De-authing the camera from the wireless network isn't necessarily going to stop it from recording. Manything for instance will pile up footage offline and sync it when it gets an internet connection again... should probably be clarified in the article that it's not stopping the recording but merely disrupting the internet connection of the camera
