Ask HN: What is the most secure way of baby monitoring?

We are expecting a baby and we want to buy a camera to monitor the baby. I want to buy an offline one for domestic use but my wife wants to buy an IP camera so that we can watch even when we are out of home. I don't trust the companies like Xiaomi and services.

What is the most secure way of monitoring babies? Is there a way to ensure e2e encryption?
