Are there legitimate recording devices that are small, like a USB drive, that only record and are encrypted? If such devices don’t exist, then the government could potentially recover the information from non-encrypted devices, and that’s bad for my threat model. If they do exist, do they cost a lot? I haven’t been able to find them. I searched on Amazon, for example, and I only found low-level spy recording devices with no encryption. If you know of any stores that have these interesting encrypted spy gadgets, please let me know. Thanks!
You can run around with meshtatic and have encrypted text. It aint a bandwidth powerhouse though, only text files.
For voice recording is one of those what you’re looking for ?
