Miku Pro, Cubo Ai, Lollipop, Nanit, Wyze, Babysense, and Owlet

It might seem like your baby monitor is magic. But that’s probably just because you don’t work with electronics very often, or you’re tired from a sleepless night. Yes, monitors do have some advanced technology, but they still sometimes experience technical difficulties. The good news is that most of them can be fixed by simply following these easy steps:

Why does my baby monitor say no signal?

First things first: Wi-Fi is a big issue for baby monitors, and it’s almost always the culprit when you can’t get them to work. If a baby monitor continually says no signal, there are a few reasons why. Sometimes this could be because of the baby monitor itself—it might not have enough power to communicate with your router or wireless network, but will still broadcast on the same channel as other devices in your house. In that case, you might need to try another channel or lower your wireless device’s power level from its default settings so that it isn’t broadcasting at full strength 24 hours a day.

If you’re using an Internet service like DirecTV Now, T-Mobile US WiFi, Netgear ReadyNAS Router Home Networking (if you’re using their app) then for sure you should use an older channel like 2 or 11 and probably reduce the power output on your router to around 50% since these networks use less juice than more modern ones.

If all else fails: Try another brand of baby monitor

How can I boost my baby’s monitor signal?

There are several ways to boost your infant optics monitor’s signal to ensure that it won’t lose connection. These can be broken down into four categories: using a high gain antenna, installing a signal booster, using a router that supports MIMO, and using a router with high gain antennas.

  • High Gain Antenna: A high gain antenna is specially designed to increase the range of the signal of your child monitor by focusing the waves in a particular direction.
  • Signal Booster: A signal booster is an electronic device that amplifies radio frequency signals for use with wireless devices, like infant optics monitors or routers. They come in two forms: Phone boosters and Pico Repeaters. Phone boosters are generally more effective at extending WiFi coverage than Pico Repeaters because they have stronger transmitters and receivers than most routers do alone; however, both types work well when installed correctly.
  • Use a Router That Supports MIMO: The primary benefit of using MIMO technology is that it increases throughput by reducing interference between multiple users connected on one network (i.e., cell phone towers). If you have trouble getting good baby monitor reception at home or in other areas where there are lots of competing signals coming through walls/windows/etc., then you may want to consider buying an 802-11ac wireless router with MU-MIMO capability — this allows for maximum performance with multiple data streams over one channel without interference from other devices nearby (like cell phones).

Do baby monitors affect Wi-Fi?

Baby monitors operate on the same 2.4 GHz frequency as your wireless router, so it’s no surprise that they can interfere with its signal. If you’re looking to understand why this happens and how to prevent it, you’re in the right place.


A Wi-Fi router sends and receives data via a wireless signal that operates on a particular frequency. Baby monitors also send and receive data using a wireless signal, but on a different channel than your Wi-Fi router uses. The more devices are active in your home that use a 2.4 GHz signal (like baby monitors), the more likely it is that they’ll interfere with each other—and if your baby monitor is interfering with your Wi-Fi router, you’re in for some major frustration.

What channel do baby monitors use?

The majority of baby monitors use a fixed frequency of 49.300, 49.830, 49.845, 49.860, 49.875, or 49.890 MHz (some have an A/B option that allows you to choose between two of these).

Digital baby monitors operate at frequencies ranging from 1.8 to 2.4 GHz. Because higher frequencies allow for more extensive functions, higher frequency digital baby monitors are more popular.

Analog baby monitors with a frequency of less than 500 MHz are generally considered to be safe. (You should still keep a safe distance between your kid and the device.) Some are as low as 49 MHz and are regarded extremely safe. The analog baby monitor becomes less safe as it approaches 1 GHz since those frequencies approach microwave frequencies (which start at around 1 GHz) and are thus more harmful.

Your microwave, cordless phone, internet, or other electronics may all be using the same frequency or channel as your baby monitor. Interference with the audio and video of the baby monitor can occur if there are too many devices operating on the same frequency. Signal loss and interference can be avoided by moving your monitor, removing sources of interference, or switching to a different brand of monitor.

Will 2 baby monitors interfere with each other?

One of the reasons you may be experiencing interference with your baby monitor is because it operates on a frequency that is shared with other wireless devices such as wireless routers and cordless phones. These devices can interfere with each other and cause your baby monitor to have weak or no signal at all.

The closer you are to the source of the signal, the stronger the signal will be. This means that if your router or phone is close by, then it may interfere with your baby monitor more than if they were further away from each other. A good rule of thumb is to keep these devices at least three feet apart from one another so they do not overlap their signals too much and cause interference.

List of Things to Try If Your Infant(baby) Optics Monitor Is Not Wroking:

Changing the channel or frequency may help

  • If you’re using a 2.4GHz router, try changing the channel and frequency on both your monitor and router.
  • Channel: Your 2.4 GHz network will have one of 11 channels to choose from—they’re in the same way FM radio stations are on different frequencies, just invisible to non-techies like you or me. There are only so many channels available before they start overlapping, so if your neighbor has a 2.4GHz network setup with the same channel as yours, it could cause interference and affect the performance of your device(s).
  • Frequency: There are actually three different 2.4 GHz frequencies (802.11b, 802.11g, 802.11n) that can be used; it’s best to use g or n because they’re faster than b (however slower than 5GHz). If one doesn’t work well for you, experiment by switching to another.*

Move the router to a better location

Move Your Router To A Better Location

Routers have a tendency to get stuck in dead zones where they can’t receive the signal they need to function. This is often the case in larger homes. If your router isn’t sending out enough data, this will cause problems with connection speed on all of your devices. Try placing your router somewhere else (like the middle of the house) so that it has an easier time sending data.

Make sure you are in range

One of the most common reasons for failure is that the baby monitor isn’t in range of your wifi signal. For this reason, it’s usually best to place your monitor where it can pick up a strong wifi signal from your router, while still keeping it closer to where you spend most of your time (such as the living room or kitchen).

If you’re unsure whether a monitor is within range, try picking it up slowly and walking around with it in hand. If at any point you notice an interruption in the video feed, then that area may be too far away to use as a permanent location for your monitor.

When placing your transmitter (the part that goes near the baby), remember that due to walls and furniture there will likely be some spots where the signal gets interrupted or fades out entirely—especially if you live in a big house. To make sure those dead zones aren’t along the path between baby and parent, consider using several transmitters around the house rather than just one; each transmitter will be able to pick up on activity within 150-200 feet, regardless of whether its route is blocked by objects or not.You should also make sure that any third-party cameras and motion sensors are connected within their own transmitters’ ranges, and set up so that they don’t get blocked by walls or large pieces of furniture.

Check the batteries

First, make sure the monitor is getting power. Check the batteries and make sure they’re not low or dead. If your monitor uses a rechargeable battery that plugs in, check that it’s plugged in and charging correctly. If you’re using AA batteries, we recommend Alkaline batteries (not Lithium), as they’ll last longer.

If your monitor isn’t turning on, double-check your connections and make sure you’ve inserted the batteries correctly—a good rule of thumb is to always insert with the positive end (+) facing up. Next, try removing the batteries for 30 seconds and then reinserting them to see if this resets the device.

Ditch the second monitor

If you’re using more than one baby monitor at once, pick the one that uses a different frequency (usually 2.4GHz or 5GHz) and turn that off. If your Infant Optics device and second monitor use the same frequency, chances are they will interfere with each other. If you have a wireless network in your home that’s connected to your Infant Optics device, it might also be interfering with the signal on this frequency.

Use a process of elimination

First, determine if the problem lies in the monitor or in the camera by trying different devices with your baby monitor’s receiver and transmitter:

  • If you can find another device that uses this same charger, use it to see if you can get your monitor working. If you can charge your baby monitor but cannot get it to work with any other device, then there is likely a problem with the transmitter (the camera).
  • If neither your phone nor tablet will connect to your baby monitor, then there may be a problem with the receiver (the charger). If this is the case, try using another charger to see if you can get it working.

Run the microwave

As mentioned above, the microwave can indeed interfere with your baby monitor. It is important to note that the baby monitor is not the only device that can be affected. The microwave and the monitor are simply not compatible, meaning that if you run your microwave while using your baby monitor, there’s a good chance you will experience interference. However, this doesn’t mean that you have to stop using your baby monitor altogether; rather than trying to find a new solution to replace both these devices simultaneously (which would likely turn out to be more expensive and less convenient), it might be better for you just to avoid using them at the same time. The next question is then: How do I know when my microwave is interfering with my baby monitor?

The baby monitor may not pick up the interference from the microwave because of one or several reasons, such as:

  • You aren’t in range of the signal
  • Your baby’s unit has been turned off

Check wireless kid toys

You’ve probably seen a toy that connects to the internet. They’re all the rage these days, from singing dolls to talking toys and beyond. While they can be a lot of fun for your little ones, their wireless signals pose an interference risk to your Infant Optics monitor. If you have one of these toys plugged in and turned on, it may be disrupting communication between your camera and display unit and causing signal loss.

To troubleshoot this problem, first unplug any offending toys. You’ll know if you have one because they usually have a red light indicating that they’re on or connected. Once you’ve disconnected them, return to your monitor and see if you can get a picture again. While this issue is best resolved by simply moving the toy elsewhere so it’s not interfering with the video transmission, in some cases it may be worth investing in a toy that doesn’t use wifi or Bluetooth connection at all.

Upgrade to a monitor with DECT

This feature essentially makes the monitor a standalone unit that operates on its own digital frequency, instead of connecting with your other wireless devices. DECT monitors use a frequency of 1.9GHz, which is not shared with any other wireless device that uses radio waves. This means that you won’t have to worry about interference from things like cellphones or microwaves—two common culprits of wireless video monitor disruptions. DECT also transmits sound and video digitally instead of analogically, meaning the signal will be stronger and clearer (with less interference) than it would be with an analog product.

Though more expensive than some analog options, DECT monitors are widely considered the most reliable way to wirelessly monitor your baby’s sleep routines without worrying about interference or static/low-quality images and sound.

Switch to a digital monitor

Before you start spending money on buying a new monitor, consider switching to a digital monitor. Digital monitors are far superior to analog, and they can be purchased at most local electronic stores (and online).

You should consider the following benefits of digital over analog:

  • Digital has less interference. This is due to the fact that when two devices are using the same frequency and one experiences interference, it will switch channels automatically. Analog also tends to flicker or “noise” when there is interference, which may wake up or irritate your child (or yourself) during nap time or at night.

Check The Antenna

If your Infant Optics video monitor has an antenna, make sure it’s connected and not damaged. If you’re experiencing a weak signal or no signal at all, fixing a loose antenna may be all you need to do to regain your connection. Just be careful not to damage the antenna when connecting it back in place. Some models of Infant Optics monitors have antennas that can be adjusted for best reception of the signal from the camera. To learn more about how to adjust your model’s antenna, check out this PDF from [this website](

Buy a replacement antenna if necessary. If you’re unable to connect or fix an existing antenna, consider purchasing a replacement part through [this website]( Replacement costs vary depending on your model: see here for further details.”

Place The Transmitter Unit On An Even Surface And At Least Six Feet Away From Other Electronic Devices

Make sure it is at least six feet away from other electronic devices such as a television, microwave, or stereo. Examples of good locations for the transmitter unit include:

  • A table or nightstand in your baby’s room
  • A desk in your baby’s room
  • A kitchen countertop near the nursery

Make sure to avoid placing the transmitter unit on the floor or on any carpeted surfaces, as this can interfere with the transmission between units and cause static during video streaming.

Difference between analog and digital baby monitors

What is an analogue baby monitor and how does it work?

An analogue baby monitor uses a continuous audio (or video) signal to transmit an analogue signal. A sending station or sending unit transforms the signal into a sequence of electrical pulses. The signal is picked up by the receiving equipment, which converts it to an auditory and/or visual signal.

As it is transmitted by the sending unit, the analogue signal is divided into smaller ‘chunks.’ Any sound picked up by the analogue signal will be included in the output. The receiving unit reassembles it after that.

Analogue baby monitor pros

  • Analog technology is more reliable and less vulnerable to interference than digital technology. For example, when you use a cordless phone, your analog monitor will not be affected by the signal.
  • Analog monitors are cheaper than digital monitors, so if you want to save money then this may be the best option for you.
  • Analogue signal strength can be seen in real time as it’s transmitted, although this won’t have any effect on the quality of the sound you hear from your monitor.

Analogue baby monitor cons

  • Analogue baby monitors can be easily hacked as they do not use any encryption or code to protect your privacy.
  • The sound quality on an analogue baby monitor is very poor so you may not hear what you need to hear at night.
  • Analogue baby monitors operate on a single frequency so if there is anything nearby that operates on that same frequency, it may interfere with your signal. For example, cordless phones and microwaves can affect the signal of an analogue baby monitor.
  • Analogue baby monitors only work over short distances so you will be restricted to the distance you can move away from the receiver while still getting a signal.

What is a digital baby monitor and how does it work?

A digital baby monitor functions in the same way that an analogue monitor does. It uses a radio frequency to send out a signal. The key distinction is that a digital signal is transmitted at a different frequency – 2.4 MHZ. It’s also encrypted, and when it’s received, it’s decoded.

A digital signal converts sound into binary code, which is made up of ‘1s’ and ‘0s.’ The digital signal is broken down and sent to the receiving device. The signal is then reassembled into the original signal from the 1s and 0s.

A digital signal understands that it needs to be reassembled in a specific order. This aids in the correction of errors that may arise during transmission. As a result, digital transmissions are crisper than analogue signals. An explanation of analogue and digital transmissions can be found on the BBC website.

Digital baby monitor pros

  • Digital video baby monitors encrypt signals for added security, so you’ll never have to worry about someone hacking into the monitor and watching your baby.
  • Digital baby video monitors usually offer two-way communication, so you can talk to and see your baby if he wakes up in the middle of the night. Many even allow you to play music through the monitor, which can be soothing as a lullaby.
  • Digital baby monitors are more durable than analog monitors because there are no moving parts that could break down over time.

Digital baby monitor cons

  • The only disadvantage is the price which they come at. Digital monitors are considerably expensive than analog monitors.
  • They generally cost around $200 and on an average, whereas analog monitors are available for less than $50.
  • This makes it difficult to purchase digital baby monitors for everyone. However, if you have the money then go ahead and buy them as they are worth it.
  • The other disadvantage that most parents have noticed is that digital monitors are not very compatible with their wireless networks.

A baby monitor is an excellent piece of equipment. They allow you to get things done around the house or get some rest while your child is sleeping. You can have peace of mind with a baby monitor. One of the first things to think about is the type you require. Do you need a digital or analogue baby monitor? The problem is deciding which one to purchase.

Choosing the proper type of baby monitor will ensure that you receive a signal that is both reliable and trustworthy. Then there are the extra features to think about. Do you require a video or audio-only baby monitor, for example? Do you require one with a temperature sensor, two-way talkback capability, and a night light built-in? There are more features, but you get the point.

After reading the previous information on analogue versus digital baby monitors, I hope you will have a better understanding of which type of baby monitor you require.
