Encrypted SD Storage

y cameras that offer this? I’m just curious. I’ve never heard of one. I’m wondering what the method would even be. I don’t really know enough about encryption technology. If the volume itself is encrypted, does the camera’s processor need to do additional work to encrypt every time it writes data, for example? If so, it might not be possible with this generation of Wyze cameras. The processing power is pretty limited.

Beyond that, if the volume is encrypted, does that mean you’d need to enter a password every time the camera restarts? If I encrypt a hard drive or partition, I have to enter the password before I unlock it, for example. I’m just trying to think about whether it seems like it would be possible, and what the implications might be.

I don’t know if other cameras do it. If they don’t… all the more reason for Wyze to do it to stand out!

As for processing power, you can check out the E2EE suggestion (End-to-End encryption (E2EE)) - someone there mentioned…

Not necessarily. You can encrypt only some parts (beginning) of keyframes and that will be enough not to allowing to decrypt it. This is how it is done in Yi and CamHi cameras.

Hopefully, this could be done with the current processing power.

As for the password needed on reboot… I suppose the most secure way (particularly assuming they enable true E2EE/Zero Knowledge, would be that you would have to either type the password, or click a button on your phone and that would securely get the needed password to the camera. Other options that are less secure but still WAY better than nothing, would be to store the password in firmware on the camera, or to store it in the wyze user account. This would still prevent people from being able to remove the SD card and view the video.
