A long-range baby monitor allows for secure monitoring in large or thick-walled homes. The stable, high-power signals maintain uninterrupted connections, giving long-range monitors an advantage as the top choice for big houses.

To compile an objective list of monitors with long-distance connectivity, we initially gathered a selection of monitors from Amazon claiming a range of over 900 ft in open-field settings. Subsequently, we analyzed 20 reviews that discussed ‘range’, while monitoring associated terms such as ‘signal drop’, ‘losing signal’, and ‘connection’ within the reviews. We combine these user reviews with our testing analysis based on our observations.

We were able to get a hold of a few top-rated long-range monitors for thorough testing. Our evaluation criteria extended beyond signal distance, encompassing signal strength at various distances, instances of signal drop, time between dropouts, outage notification settings, distance before complete outage, multi-channel communication, and the longest distance for signal presence. Additionally, we assessed signal-boosting features like antennas and stability enhancements such as DECT6.0 technologies.

Our test location had only one floor, yet the signal strength was excellent, reaching the furthest corner of the upper floor and even penetrating the basement. I was extremely impressed that the signal remained at over 80% when the camera was placed on the ground floor, regardless of whether it was in the basement or the upper floor.

I appreciated the green light as a reliable signal connection indicator. It was intuitive and only experienced the blinking green (the loss of signal indicator) when the display was close to a router or when the parent unit was positioned over several thick walls.

Another thing that I found to affect the transmission range for this monitor is the battery charge. When the battery has been in use for more than 5 hours and is approaching 30%, the signal starts dropping and the easiest way to fix this is to recharge the parent unit battery.

This unit utilizes secure FHSS transmission technology, which is significantly more reliable compared to DECT monitors that do not encrypt their signals and are known to be more susceptible to interference. For instance, the Panasonic Long-Range Monitor has been recognized for maintaining good range but is plagued with bugs and features the most user-friendly interface imaginable. While DECT claims to transmit signals up to 1500 ft range, the quality of video and audio signals is terrible compared to Bonoch’s video and audio signals.

This monitor also impressed me with the SD card slot which makes it possible to record videos continuously for up to 48 days using a 128 GB MicroSD card. This feature made Bonoch stand out over Infant Optics DXR 8 Pro which we also considered for its stable long-range transmission.

What I also found to contribute to Bonoch’s long-distance transmission from its camera to the display unit is the large-capacity battery of 7800 mAh which is 5000 mAh bigger than Infant Optics Pro’s 2800 battery capacity. Battery power strength is known to increase the signal strength of the transmitting unit making it possible to go further distance compared to what it would normally do.

Infant Optics DXR 8 Pro:

If you prefer a long-range baby monitor for big walls with an excellent rating when it comes to signal stability, consider Infant Optics DXR 8 Pro. It boasts of up to 1000 ft range as claimed by the manufacturer and it maintains connection up to 920ft range in open area with no obstructions.

When used indoors with thick walls, it reliably sends signals through 5 thick walls or 8 regular walls in a large home. The distance between the camera and the parent unit exceeded 70 ft, slightly shorter than Bonoch, but the signal connection stability was better in DXR 8 Pro. Its signal strength ranged from 3 and 5 bars when it was around 40 ft distance to when it was approaching its 70 ft range max indoors.

This DXR 8 Pro model doesn’t record as Bonoch but features HD video display of 720p which was slightly less clear compared to Bonoch’s 1080p HD display. Pro model also lacked in that it didn’t feature an SD card slot to allow for recording.

In situations where DXR 8 Pro model lost connection and was within the 70ft indoor range, we found it easy to boost its signal by simply adjusting the antennae to a vertical position. Eliminating devices that interfered with DXR 8’s signals such as WiFi routers and other wireless networks also significantly improved the transmission range.

When we counted the number of signal drops over 8 hours(single night), we had only 4 instances which is considerably less than Bonoch’s 6 instances and the original DXR 8’s 10+ instances. Infant Optics did make an effort to improve signal connection stability in their upgraded DXR 8 Pro model.

I was also impressed by the clarity of the audio signals from the Infant Optics DXR 8 Pro. Even when I increased the distance between the camera and the display unit, the static noise was minimal, thanks to the active noise-reduction feature built into the speaker. For example, when we placed the camera on the first floor and walked to the opposite end of our large house, which is approximately 60 ft away, I could still hear my baby’s breathing without any distortion.

In a few instances, I was able to utilize its remote pan/tilt/zoom (PTZ) feature to reposition the camera so it could capture a wider view of the nursery. This feature came in handy when my baby was moving around while sleeping and I wanted to keep an eye on him without having to physically enter the room.

For camping adventures, this Pro unit is excellent as it comes with a backup battery and very audible notifications when the signal gets lost. For example, during our camping trip, I could hear the continuous beeps when we were outside the monitored range and the notifications would stop once we were back in range. No need to restart the device or to repair it to restore the connection. It automatically picks up the signal once it is back in range.

It didn’t bother me much but some people may find the beeping alert notification when the monitor is out of range to be annoying. It is a small price to pay for the convenience and peace of mind this baby monitor offers.

VTech VM1211:

For the audio baby monitor with the longest range ideal for thick walls, consider the VTech VM1211. Our tests showed it can penetrate 6 walls and reach 110 ft, while BabyGearLab’s testing revealed it exceeded 7 walls and reached a range of 170 ft. This is super impressive and is partly contributed by its use of latest telecommunication technology called DECT 6.0 which has been fine-tuned for distance and is employed in most walkie-talkies.

While we didn’t compare Vm1211 with the Hatch Rest monitor in our testing, BGL’s testing found that VM1211 is almost comparable to the Hatch Rest+ sound machine which also acts as a Wi-Fi-based audio baby monitor.

When we tabulated its instances of signal drop, it was the lowest. But that could be because we used it in an interference-free environment, as is our standard testing process. While its signal experienced some static when interference was introduced, it was not frequent enough to be a cause of concern.

Compared to DM111, this unit is a significant upgrade in that it features a baby-activated open mic, a high-sensitivity microphone with adjustable volume that can pick up even the faintest cries. It also has a night light and lullabies. The only downside is its permanent glow when turned on.

Panasonic Long Range Video Baby Monitor KX-HN4101W

If you prefer a DECT monitor with a super-extended range with smart features such as motion and cry detection, the new upgraded Panasonic KX-HN4101W is your best pick. DECT 6.0 technology utilizes the 1.9 GHz frequency band which provides better range and less interference compared to the 2.4 GHz band used by other monitors in this category.

The limited number of devices that utilize the 1.9GHz, a frequency dedicated for telecommunication devices, gives this monitor the advantage of low and less crowded channels making its transmission interference free and much more improve signal stability.

The KX-HN4101W has an excellent reach of up to 1500 ft in open spaces, making it perfect for thick homes or large homes. Its microphone is very sensitive and can detect even the slightest sounds from your baby’s room. You can adjust the volume of the microphone to suit your preferences by simply pressing a button on the parent unit.

Another great feature of this monitor is its ability to detect motion and sound, and send alerts to your parent unit or smartphone. This way, you can be alerted if your baby wakes up or moves around in their crib without having to constantly check the video feed.

The KX-HN4101W can connect up to four cameras, allowing you to monitor multiple rooms simultaneously. It also has a split-screen feature that displays feeds from different cameras on one screen, making it easier to keep an eye on your little ones.

The parent unit has a large 3.5-inch color screen that provides clear and crisp images of your baby. You can also remotely pan, tilt, and zoom the camera to get a better view of your baby’s room. Plus, the monitor has infrared night vision, so you can check on your baby even in low light conditions without disturbing their sleep.

How to pick the best baby monitor for extended range for thick walls:

Choosing the best baby monitor for extended range involves considering several factors to ensure you select a model that meets your specific needs. Here’s a comprehensive guide:

  1. Type of Monitor:
    • Audio vs. Video: Decide whether you need just audio or both audio and video monitoring. Audio monitors tend to have longer ranges than video monitors.
    • Analog vs. Digital: Digital monitors offer more privacy and less interference from other devices than analog. However, they may have a shorter range due to the complexity of the signal.
  2. Range:
    • Check Manufacturer’s Range Specifications: Look for monitors that advertise an extended range. Keep in mind that these specifications are often based on clear line-of-sight conditions, and walls or floors will reduce the effective range.
    • Consider Your Space: Think about the distance between where you’ll place the monitor and where you’ll be. If you have a large home or want to take the receiver outside, look for monitors designed for long distances or outdoor use.
  3. Frequency Band:
    • 2.4 GHz vs. 900 MHz: Monitors operate on different frequency bands. A 900 MHz monitor might have a longer range and less interference from Wi-Fi devices than a 2.4 GHz monitor, but it might also offer lower quality audio and video.
  4. Battery Life:
    • Long Battery Life: For portability and extended use, look for a monitor with a long battery life or one that offers both battery and plug-in options.
  5. Technology Features:
    • DECT Technology: For audio monitors, DECT (Digital Enhanced Cordless Telecommunications) technology offers a secure connection with minimal interference and can sometimes provide a longer range.
    • Wi-Fi Enabled Monitors: These monitors use your home Wi-Fi network to transmit the signal and can often offer unlimited range as long as you have internet access. However, they depend on your Wi-Fi’s stability and speed.
  6. Test Return Policy:
    • Check Return Policies: Since performance can vary greatly depending on your home’s layout and construction materials, it’s wise to purchase from a retailer with a good return policy, allowing you to test the monitor in your own space.
  7. Read Reviews and Recommendations:
    • Look for User Feedback: Online reviews and recommendations from other parents can be invaluable. Pay attention to comments about the monitor’s range in real-world conditions, not just the manufacturer’s claims.
  8. Safety and Privacy:
    • Secure Transmission: Ensure the monitor uses encrypted signals to prevent unauthorized access, especially important for Wi-Fi or internet-connected devices.
  9. Additional Features:
    • Consider Extra Features: Some monitors offer features like temperature sensors, lullabies, night vision, or two-way talk functions. Decide which features are must-haves for your family.

Go for baby monitors with antennae as they have super long extended distance:

Antennas play a crucial role in increasing the range of baby monitors by enhancing the signal strength between the transmitter (the baby unit) and the receiver (the parent unit). Here’s how antennas help in extending the range of baby monitors:

  1. Signal Transmission and Reception: Antennas are responsible for transmitting and receiving radio signals. A well-designed antenna can more efficiently capture and broadcast signals, even over longer distances. This means that the monitor can send and receive audio and video data more effectively, reducing the likelihood of signal loss or degradation over distance.
  2. Antenna Type and Design: The type and design of the antenna can significantly impact the range and performance of a baby monitor. Some common types include:
    • Omni-directional antennas: These antennas send and receive signals in all directions, making them ideal for general use in homes where the direction of the signal cannot be controlled.
    • Directional antennas: These focus the signal in a specific direction, which can significantly extend the range in that direction. They are less common in baby monitors but can be found in some models designed for extended range.
  3. Improved Signal Strength: By increasing the signal’s strength, antennas can help maintain a clear connection over greater distances. This is especially important in environments with obstacles like walls, floors, and furniture, which can weaken or disrupt the signal.
  4. Reduced Interference: Some antennas are designed to reduce interference from other wireless devices in the home, such as Wi-Fi routers, cordless phones, and microwave ovens. By improving the monitor’s ability to maintain a clear signal, these antennas can indirectly extend the usable range of the device.
  5. External vs. Internal Antennas: Many baby monitors come with internal antennas, but some models have external antennas that can be adjusted or extended to improve signal reception. External antennas, especially when fully extended, can often provide a better range than internal ones.
  6. Antenna Placement: The placement of the baby monitor and its antenna can also affect range. Elevating the monitor or positioning its antenna away from obstructions can help optimize signal transmission and reception.
  7. Aftermarket Antenna Upgrades: For some models, it’s possible to purchase aftermarket antennas designed to increase range. These antennas can replace or augment the existing antenna, improving the monitor’s overall performance.

By enhancing signal strength, reducing interference, and ensuring efficient transmission and reception, antennas are key to extending the operational range of baby monitors. This allows parents to monitor their children over larger distances, providing peace of mind while reducing the risk of signal dropouts or poor audio/video quality.

Below are some monitors with antennae that can play a role in enhancing range:
