I’ve spent countless hours testing baby monitors here at NerdTechy, and the Momcozy BM04 has caught my attention with its dual connectivity approach. If you’re tired of choosing between WiFi and traditional wireless monitors, this might be your solution.
Momcozy was nice enough to provide me with a sample to borrow and test out over the past 3 weeks. In that time, I’ve had a lot of experience with it.
I’ll share my hands-on experience with its standout features, including the smart app integration and safety zones, plus a small quirk you’ll want to know about before making your decision.
Key Takeaways
- The Momcozy BM04 offers dual connectivity through WiFi and 2.4GHz wireless, allowing flexible monitoring options via smartphone app or dedicated parent unit.
- Camera delivers 1080P HD video quality with automatic night vision and clear two-way audio communication.
- Safety Fence feature creates virtual boundaries and sends instant alerts when baby crosses designated danger zones.
- Compatible with iOS and Android through the Momcozy app, enabling easy access sharing and remote monitoring capabilities.
- Supports both cloud and local storage options with microSD card compatibility for recording important moments in HD quality.
Dual Connection
Unlike traditional baby monitors that rely on a single connection type, this Momcozy baby monitor’s dual connectivity through both WiFi and 2.4GHz wireless gives parents unprecedented monitoring flexibility.
I’ve found this dual-mode capability to be a game-changer, as it guarantees I can keep an eye on my baby whether I’m in the next room or across town.
The WiFi connection pairs with the easy-to-use Momcozy app, letting me check on my little one from anywhere with internet access.

Meanwhile, the 2.4GHz wireless connection provides reliable, interference-free local monitoring when I’m at home. It provides up to 1,000 feet of range, but a little less with walls and obstacles in the way. Regardless, I don’t have any connection issues within my 2,000 sq. ft. two-story house.

This smart baby monitor maintains a secure, stable connection in both modes, which gives me peace of mind knowing I’ll never lose sight of what’s happening in the nursery. Even with many other wireless devices in the home, there’s no issues with interference.
Smart App
While many baby monitor apps can feel clunky or unreliable, the Momcozy app stands out for its exceptional user-friendliness and stability.
I’ve found it works flawlessly on both iOS and Android, letting me check on my baby from anywhere with an internet connection.

What I love most is how easy it’s to share access with family members. Once they download the app, I can grant them permission to view the nursery – perfect for letting grandparents watch their grandchild grow.
The app packs all essential features: live streaming, two-way communication, recorded footage playback, lullaby controls, and cloud storage setup.
You’ll also find access to all of the same settings that you can configure through the monitor itself including offline notifications, display preferences, sound controls, firmware updates, and more.
I’m thoroughly impressed that it maintains consistent performance without crashes or connectivity issues, regardless of if I’m using it on an Android or iOS device.
Video and Audio Quality
After testing the Momcozy smart baby monitor extensively over the past 3 weeks, I’m thoroughly impressed with its outstanding video and audio capabilities.
The camera delivers crystal-clear 1080P footage in all lighting conditions, with the night vision feature automatically activating in low light to guarantee complete visibility across the room.

During the day, you’ll enjoy rich, vibrant colors without any pixelation or blurriness.
The audio quality matches the exceptional video performance. The camera’s built-in microphone captures and transmits sound perfectly, allowing for clear two-way communication with your baby.
I’ve found that when using the talk-back feature, my voice comes through the camera speaker with remarkable clarity – there’s no distortion or muffling that could confuse or startle your little one. My baby can instantly recognize my voice and feel a sense of comfort that I’m nearby.
Safety Fence
The Safety Fence feature of the Momcozy baby monitor sets it apart from typical baby monitors by letting parents establish virtual boundaries within the camera’s view.
I love how this feature helps me keep my baby safe by creating custom “danger zones” that trigger immediate alerts if crossed.
- Set up virtual boundaries to give you instant app notifications when your baby leaves a designated safe area.
- Receive instant push notifications through the smartphone app when boundaries are crossed
- Get real-time alerts directly on the parent monitor unit
- Monitor multiple zones simultaneously with customizable alert settings

What makes this safety feature particularly valuable is its dual-notification system – you’ll know immediately if your little one ventures into restricted areas, whether you’re using the app or dedicated monitor.
It’s a game-changer for parents who want an extra layer of security in their nursery monitoring.
Auto Recording
Recording capabilities set the Momcozy dual mode baby monitor apart from standard baby monitors, offering both cloud and local storage options for capturing your baby’s precious moments.
I’m impressed that you can save video clips with sound in clear 1080p quality, which comes in handy for documenting milestones or reviewing any nursery incidents.
What I find especially convenient is the flexibility in storage options. You can choose to store recordings either in the cloud or locally by inserting a microSD card directly into the camera unit.

Essentially, this means I don’t have to worry about running out of space or losing important footage. Just note that a microSD card is not included and must be acquired separately.
Whether you want to capture your baby’s first steps or monitor overnight activities, the Momcozy smart baby monitor’s recording features guarantee you’ll never miss those special moments.
Potential Downsides
While my overall experience with the BM04 has been overwhelmingly positive, I’d be remiss not to mention its limited WiFi compatibility as a very minor drawback.
The monitor only supports 2.4GHz WiFi networks, not the faster 5GHz band that’s becoming increasingly common in modern homes. However, I’ve found that the 2.4GHz connection handles video streaming remarkably well, making this limitation barely noticeable in daily use.

- No support for 5GHz WiFi networks, which typically offer higher bandwidth
- Limited to 2.4GHz band connectivity
- May experience slightly lower bandwidth for video streaming
- Could affect performance in homes with complex network setups
Despite this single limitation, I can confidently say that the BM04’s actual performance hasn’t been compromised, as the video quality and streaming reliability remain excellent on the 2.4GHz frequency.
Final Thoughts
All in all, I’ve found the Momcozy 5-Inch Dual-Mode Smart Baby Monitor to be a reliable companion for keeping tabs on my little one.
Despite its 2.4GHz WiFi limitation, the dual connectivity options, crystal-clear video quality, and smart features through the app make it worth considering.
Overall, I’m confident recommending this monitor to parents seeking a balance of functionality and peace of mind.
