I live in a country all properties are walled by default, I have a camera pointed at my front door and one at my garage door and then other cameras inside around the house. None captures any neighbor, just a bit of my sidewalk in front of my door/garage door. Those cameras use coaxial cables connected to a DVR inside my house recording the footage on an HDD. No internet connection, no image being transported through Wi-Fi or Bluetooth... but also no encryption anywhere... how hackable are these?

    The video is focused on cloud/internet enabled security cameras. A security system that isn't internet accessible and only stores footage locally is not of any concern unless you think someone would break into your house to take the HDD's themselves.

    Talking about the Tempest Attack he mentions, which he tested in other video as well, accessing the camera feed with an antenna capturing electromagnetic emissions, but he was doing it on those wireless cameras so perhaps cabled cameras are safer. I did a quick research here, and if it was analog signal it would be easier, but for HD-over-Coaxial it's more complex because they use multiple bandwidths and each model has different modulation schemes, also they have less leakage so they'd need to be really close to get it, making trying to get access to the feed from inside my property very troublesome.
    Unintentionally, having second-rate equipment turned out to be a very secure option lol

    I'd be more worried about the corporate and state actors in your case. A criminal would have to already have intimate access to your home to snatch your video feed, so I wouldn't worry about that. If you do find a way to encrypt the video before saving to the HDD, that would protect you against police or insurance companies viewing the footage without your key.

    ETA: Though, NOT providing the key may give them reason to believe you have something to hide and pit them against you. 🤷
