Go for it if you...
You want a non-WiFi video camera without spending much
You want the feed kept off the internet with no cloud account
You want a sound-activated eco mode to quiet the signal when the room is calm
You do not want any monthly subscription
You want the lowest emission and no hacking risk above every other feature
You are comfortable listening to your baby rather than watching a video screen
You want a monitor that keeps working even when your home internet goes down
You never want to pay a monthly subscription to use what you bought
The main thing to know
The picture is usable but softer than full HD, which is the honest trade for the low price.
This is an audio monitor with no camera, so if seeing your baby on a screen matters to you, this is not the one.
Skip this if you...
You want the sharpest possible HD picture
You want breathing or vitals tracking
You cannot mount the camera at least three feet from the crib
You want to see your baby on a video screen
You specifically want a published, independent emission measurement
You want breathing or vitals tracking
Neither of these quite what you're looking for?
