Our Full Review
Not every parent needs a video monitor with night vision, temperature sensors, and an app that sends notifications. Some of us just want to hear if the baby is crying. The VTech DM221 does exactly that and does it reliably. DECT 6.0 technology means it won't interfere with your Wi-Fi and can't be accessed over the internet (so no creepy monitor hacking stories). The range is solid at up to 1,000 feet, which covers most houses and backyards. It has a sound-activated LED display on the parent unit so you can see audio levels when the volume is off. The rechargeable parent unit lasts about 18 hours on a charge. We've used ours for two kids and it still works perfectly. There's a two-way talk-back feature that we honestly never used, but it's there. Sometimes simple is better, and at under $30, this is the best value in baby monitors.
What We Like
- DECT 6.0 signal can't be hacked and won't interfere with Wi-Fi
- Dead simple to set up, just plug in and it works
- Rechargeable parent unit lasts 18 hours so you won't wake up to a dead monitor
- Sound-activated LED bars let you see noise levels with volume muted
- Under $30 makes it the best value baby monitor by a mile
What Could Be Better
- Audio only, no video if you want to see what baby is doing
- The two-way talk feature has noticeable static
- 1,000-foot range is fine for most homes but might not reach a detached workshop
Safety Notes
Keep all monitor cords at least 3 feet away from the crib. Never place the baby unit inside the crib. DECT technology provides a secure, encrypted signal. Test the monitor from various locations in your home before relying on it.
Buying Guide Notes
If you just want reliable audio monitoring, save your money and get this instead of a $200 video monitor. If you do want video, the Infant Optics DXR-8 Pro is our pick but costs 5x more. For a Wi-Fi connected option, the Nanit is great but comes with a subscription fee. This VTech is perfect as a backup monitor or for travel too.
