Can confirm. Been using Wyze cameras for several years.

I’m not using this particular firmware but I bought them specifically because I could flash them.

Despite the firmware giving control of outbound traffic, I suggest blocking them at the network level.

Mine run on an sd card and if someone removes the sd card and reboots it or the card gets corrupted, it would fall back to factory settings.

I have quite a few of these and they are using very, very cheap sd cards and while none have failed, they most certainly will eventually.

Though it looks like that could change eventually with a Linux phone.

Nope. There is firmware on cellular modems that is controlled by the chip vendor.

Carriers work with chip companies to make sure devices work on their network but they don’t even get the source, just early release blobs for the network engineers head of the device’s release.

This code is literally the most widely used closed source code. It is more locked down than the firmware on any other device you own. It often illegal to reverse engineer.

I’m sure one day there will be open source code for this but it’s going to come long after a Linux phone and until we can be anonymize with the tower, there is no privacy.

emulate it perfectly

This is a far stronger claim than any of the developers for these emulators claim.
