End-to-end video encryption means that only you can see who is at your door. It is used to prevent law enforcement from seeing who is delivering packages. While not offered by Nest, you can install it on Ring provided the device isn’t on battery power. Installing end-to-end encryption is simple. Disconnect the video doorbell by removing its inner rechargeable battery from the casing. Connect it to your home’s doorbell wiring, and then enable end-to-end encryption.
