  • I'd add one measure: alarm on port status change. This would alert you to that something happened. Commented 2 days ago
  • The biggest problem with wireless cameras is radio jamming attacks. Your suggested mitigation decreases security and increases risk. Commented 2 days ago

    @MichaelAltfield jamming is only an availability issue. One shared by ... obscuring the lens. So, I'm not sure the wireless media is appreciably riskier in terms of availability. In no way does my suggestion "decrease security" nor does it increase risk. Your stated threat model is a dropbox and unauthorised access to the transmission. Now you are concerned about availability. You're going to have to clarify what threats you are actually concerned about, else no one will be able to answer you to your satisfaction.

    @schroeder I'm actually with OP on this one, WiFi is a bad choice for security cameras. And I'd argue that a security camera availability issue is a security issue, since the camera failing to record is a breach. "Jamming" WiFi is not even particularly difficult; it can be done with any Linux device by transmitting deauth frames. There are many reports of thieves doing just that to evade cameras. So yes, switching from wired to WiFi does appreciably increase risk. Commented 2 days ago

    @josh3736 as I mentioned, it increases certain kinds of risk. The OP is wanting to combat network access threats. Wireless is a valid suggestion. Are you aware of the mitigations against deauth attacks? So, that can be dealt with. Leaving signal jamming. But again availability attacks are no different from physical interference, so the risks are equal even if you use a wired connection. Two words: "painball gun". I'll repeat: wifi cameras are not a security risk, insecure wifi cameras are a security risk. Commented yesterday
