Most baby monitor buying guides compare night vision, range, and app quality. Those matter, but the question worth asking first is different: can someone other than you actually watch the feed? Here's what separates a genuinely secure monitor from one running a factory-default password anyone can look up.
Wi-Fi vs. non-Wi-Fi — the real tradeoff
Non-Wi-Fi monitors, the kind that use frequency-hopping spread spectrum technology to switch channels constantly, are effectively immune to the online hacking and data-breach risks that Wi-Fi models carry 1. The tradeoff is real too: no remote viewing from your phone when you're not home, no cloud recording. For a lot of parents that's an easy trade, since the main use case is a monitor in the next room, not remote access from work.
What "encryption" actually needs to mean
If you do go with a Wi-Fi monitor, the marketing word to look past is just "secure" — look for the actual spec: end-to-end encryption, ideally 256-bit, the same category of protection used for banking apps 1. A monitor that doesn't list an encryption standard at all is one where you genuinely don't know what's protecting the feed.
This isn't a hypothetical risk. In 2013, a hacker used a compromised monitor to shout at a sleeping toddler in Houston. In 2019, an attacker used stolen, reused passwords to access 300 different Nest cameras in under ten minutes — not by breaking encryption, but because the owners had never changed a default password1.
FCC certification and radiofrequency — a more honest answer than a reassuring one
Every wireless baby monitor sold in the US has to meet FCC radiofrequency exposure limits that have applied to consumer electronics since 1996 3. What's worth knowing honestly, rather than glossing over: those limits haven't been updated in decades and don't set a separate, stricter standard for infants specifically, which is a real point some researchers have raised 4. Nothing here means a standard monitor is dangerous — it means that if you'd rather not think about it at all, a non-Wi-Fi or audio-only monitor placed a few feet from the crib, which most manufacturers already recommend as a minimum distance, sidesteps the question entirely rather than resolving a debate that's still open.
Five things to actually check before buying
You can change the default username and password immediately during setup — not buried in a menu, not optional.
The manufacturer pushes automatic firmware updates, since that's how known security bugs actually get fixed.
Two-factor authentication is offered for the companion app, if it's a Wi-Fi model.
For non-Wi-Fi models, the listing specifically mentions frequency-hopping — a plain "digital" label isn't the same thing.
The brand has an actual security track record, not just a marketing page that says "secure."
