The Momcozy BM04 is a flexible choice for monitoring 2 rooms at once, with 2 cameras, a 5-inch 1080P split screen, a parent unit and optional 2.4GHz Wi-Fi app access. Its main trade-off is choosing between local parent-unit viewing and Wi-Fi features.

The Momcozy BM04 is a good fit for parents who want 2 nursery views on one screen, plus the choice of a local parent unit or Wi-Fi app access. Its 5-inch 1080P split screen is designed for twins, siblings in separate rooms, or a nursery and play area.
The main decision is how you plan to watch. Use the parent unit for at-home viewing without Wi-Fi, or pair the system with the Momcozy App for live-feed access away from home on a compatible 2.4GHz network.
The Momcozy BM04 at a glance
The Momcozy BM04 combines 2 cameras, a 5-inch 1080P split screen and optional Wi-Fi access in one monitoring system. It can show both camera feeds side by side, so you don't have to switch between rooms.
Momcozy BM04 Smart WiFi Baby Monitor: Best for monitoring 2 rooms
- 2 cameras
- 5-inch 1080P split screen
- Parent unit and Wi-Fi app access
- Supports up to 4 cameras
- 2-way audio
A strong fit for parents who want 2 camera feeds visible together on one parent-unit screen, with optional app access when away from home.
Pros
- Shows 2 camera feeds at once
- Offers parent-unit and Wi-Fi viewing
- Includes 2-way audio
- Supports up to 20 shared users
Cons
- Wi-Fi pairing supports only 2.4GHz networks
- Camera placement affects night-vision clarity
- A split screen gives each feed less display area than a full-screen view
The system supports up to 4 camera connections, although this package includes 2 cameras. That gives you room to think about future coverage, but the included setup already targets the common need to watch 2 spaces.
The 5-inch screen is large enough to show 2 feeds together while keeping the parent unit compact. Each feed occupies part of the display in split-screen mode, so a full-screen view may still be easier when you need to study one room closely.
Who should consider this Momcozy baby monitor?
Choose the BM04 if you want one parent-unit screen for 2 camera views. It makes sense for twins sharing or using separate spaces, siblings in different rooms, or parents who want to monitor a nursery and play area.
The optional Wi-Fi connection also suits families who want app access when away from home. If you only want a local monitor, the non-Wi-Fi parent unit keeps the basic at-home viewing path separate from the app.
You may prefer a simpler single-camera monitor if you only need one room and don't expect that to change. For a wider look at camera types and setup choices, see our guide to the best baby monitor system.
How does the BM04 display 2 camera feeds?
The BM04 uses a 5-inch 1080P split screen to show 2 camera views side by side. This arrangement helps you compare rooms at a glance instead of moving back and forth between separate feeds.
That layout is useful when both rooms matter at the same time. For example, you can keep one camera on a nursery and another on a play area, then check both views without changing the selected camera.
The trade-off is screen space. A split screen gives each feed less area than a single full-screen view, so you may want to switch your attention to one feed when checking a small detail.
The 2-camera package also reduces the need to buy a second camera immediately. Since the system supports up to 4 camera connections, it can cover more rooms if your monitoring needs grow and compatible additions are available.
Parent unit or Wi-Fi app: which viewing option fits?
The parent unit is the better choice for local monitoring at home without Wi-Fi. It gives you a dedicated way to view the cameras, which can be useful when you want a separate screen near your usual evening routine.
The Wi-Fi path adds remote access through the Momcozy App. That can help when a parent is away from home or another family member needs approved access to the live feed.
Wi-Fi pairing supports 2.4GHz networks only. Check your router settings before setup, especially if your home uses separate network names or a band-selection feature.
The system also supports up to 20 shared users. That may help grandparents, relatives and other trusted family members stay connected, but review sharing permissions carefully and only invite people you want to access the video.
For families that prefer to avoid app access, compare this setup with our guide to best baby monitors without Wi-Fi. If screen size is your priority, our best baby monitors with large screens guide covers another important part of the decision.
Is the BM04 useful for twins or separate rooms?
The BM04 is especially suited to twins, siblings in separate rooms, or a nursery and play area because 2 camera feeds can appear together. You can place the cameras where the two spaces need coverage, then use the split screen to check both areas.
This setup can reduce the need to carry one monitor between rooms. It also gives you a consistent view when one child is sleeping and another is playing.
Think through camera placement before mounting anything. The screen can show both rooms, but its usefulness still depends on each camera having a clear view of the area you want to monitor.
If you only need to watch one crib, a second camera may be unnecessary. In that case, a single-camera monitor may offer a simpler setup, while the BM04 makes more sense when 2-room coverage is part of your normal routine.
How should you position the BM04 cameras?
Position each camera at least 24 inches above the baby when using a crib mount. Momcozy also advises keeping a wall or floor stand within 16 feet of the crib horizontally so infrared night vision has enough light to show the baby's face clearly in darkness.
Measure the distance before fixing a camera in place. A camera that is too low may have a misaligned focal length, which can make the image blurry.
Keep cords and mounting hardware out of the baby's reach. Follow the camera's installation instructions, make sure the mount is secure and check the view from the parent unit before settling on the final position.
Avoid mounting based only on daytime framing. Turn on night viewing and check whether the baby's face remains visible from the chosen angle and distance.
The camera setup should also match the room's purpose. A nursery camera may need a crib-centered view, while a play-area camera may need a wider position that shows the space where the child usually moves.
How does the BM04 perform for nighttime viewing?
The BM04 provides night vision through both cameras, so you can check the feeds in complete darkness. The clearest result depends on camera height, horizontal distance and the angle toward the crib.
Use the parent unit to check the night view after installation. If the image is blurry or the baby's face is difficult to see, adjust the position before relying on that camera overnight.
A split screen helps you keep both rooms visible, but each feed is smaller than a single full-screen image. Switch to one camera when you need a closer look at one child.
Night vision helps you see movement and room activity, but it doesn't replace safe sleep practices or direct supervision when a child needs attention. Use the monitor as an aid for checking the room, not as a substitute for being nearby when necessary.
If breathing movement is a specific concern, read our guide on how to choose a baby monitor with a breathing sensor. A standard video monitor and a breathing-sensor monitor serve different purposes.
Can you talk to your baby through the BM04?
The BM04 includes 2-way audio, with a microphone that picks up sounds and a speaker that lets you speak through the parent unit or your phone. That can help you offer brief reassurance without walking into the room immediately.
Use the feature in short, calm exchanges. A monitor speaker can support communication, but it doesn't tell you why a baby is crying or whether the child needs direct care.
The parent unit gives you the local audio path, while the phone option connects to the Wi-Fi viewing experience. Decide which device you'll keep close during naps and nighttime routines.
Audio sensitivity can also affect how often you check the screen. Listen for meaningful changes rather than treating every small sound as a reason to interrupt sleep.
What are the BM04's privacy and sharing choices?
The BM04 offers a non-Wi-Fi parent unit and an encrypted Wi-Fi connection, giving you two ways to think about privacy. Local parent-unit viewing avoids the need to use the app for ordinary at-home monitoring.
The Wi-Fi option is useful for remote access, but it adds account and sharing decisions. Momcozy states that advanced encryption technology protects the baby's video, and the system supports up to 20 shared users.
Use only trusted accounts and review who has access. Remove people who no longer need to see the feed, and keep login details private.
The BM04 is FCC certified. The publicly accessible FCC reports identify the monitor as 2A6UA-BM04-A and the camera as 2A6UA-BM04-B.
You can review the FCC equipment authorization records if you want to look up the certification identifiers.
What are the main trade-offs?
The BM04's biggest strength is flexible viewing across 2 rooms. The split screen, parent unit and optional app access cover more situations than a monitor built only for one local feed.
Its main limitation is that the Wi-Fi path supports 2.4GHz networks only. Families with a different router setup may need to adjust their network or rely on the parent unit for at-home viewing.
The 5-inch display is also a compromise between portability and detail. It can show 2 feeds together, but each feed is smaller in split-screen mode than it would be on a single full-screen display.
Camera placement matters as well. The night-vision guidance is specific, so a room that can't accommodate the recommended height and distance may take more planning.

Is the Momcozy BM04 worth choosing?
The Momcozy BM04 makes the most sense when you need 2-room coverage and flexible viewing. Choose it for twins, siblings in separate rooms, or a nursery and play area where a single 5-inch split screen can show both cameras.
Pick the parent unit when you want local at-home monitoring without Wi-Fi. Use the app when remote access matters and your network supports 2.4GHz pairing.
Before setup, measure each camera position, confirm the night-view distance and decide who should receive shared access. If you only need one room, a simpler single-camera monitor may be easier, but the BM04 gives you more coverage options when 2 feeds are part of everyday nursery monitoring.
