Baby monitor making crackling noise was the first problem I faced as a new parent. The static sound kept me on edge, and I couldn’t relax. At first, I thought it was just a small glitch. But after trying HelloBaby, VTech, and even Motorola, I learned there were real reasons for the noise. Over time, I found out what caused it and which quick fixes worked best. In this guide, I’ll share my own story, the steps that helped me, and the monitors I now trust. Let’s get you clear sound and peace of mind again.

Why Is My Baby Monitor Making a Crackling Noise?
Short answer: the link is weak.
One unit sends the sound.
The other unit gets the sound.
Short answer: nearby gear can clash.
WiFi and phones can harm the link.
I had a HelloBaby next to my router and it buzzed.
Short answer: low power makes hiss.

If the cam is far, sound drops.
Keep the parent unit close to the cam.
Short answer: bad cords make noise.
Check the plug and the cord.
Swap the cord to test the sound.
Short answer: room hum can sound like hiss.
Fans, white noise, or a pump can hum.
Turn these off to see if it helps.
In short: check link, charge, range, cords, and room.

Most of the time the hiss will stop.
Brand-Specific Issues I’ve Experienced
HelloBaby:
Short answer: most crackling comes from interference.
When I used my Hello Baby monitor near thick walls, the sound broke up.
It got worse when my Wi-Fi router was close by.
Moving the unit and keeping it away from both walls and the router cleared the sound.
VTech:
Short answer: weak batteries cause static.
My VTech baby monitor made a lot of noise once the battery got old.
At times, the sound also clashed with my cordless phone.
Replacing the battery and keeping it away from the phone fixed the problem.
Motorola:
Short answer: old software creates noise.
My Motorola monitor often hummed for no reason.
Later I found out the firmware was outdated and clashed with nearby devices.
Once I updated it and used a stable outlet, the hum was gone. Check price on Amazon
Babysense:
Short answer: the mic picks up room hum.
My Babysense was quiet most of the day.
But at night, it caught the low hum of the air purifier and even the ceiling fan.
It wasn’t broken—it was just very sensitive. Check current price
In short: HelloBaby often struggles with walls and Wi-Fi, VTech with battery and overlap, Motorola with software and power, and Babysense with background hum. Knowing these quirks makes it much easier to fix the crackling.
Some parents even switch to Philips Avent or Nanit for better sound clarity. If you’re curious, here’s a comparison: Philips Avent Baby Monitor vs Nanit: Trusted Parent Insights
Why Baby Monitors Crackle at Night or While Sleeping
Short answer: baby monitors often crackle more at night because of extra devices, blocked signals, or silence.
I noticed my monitor always sounded worse once the house was quiet. At first, I thought it was broken. Later, I learned that silence made each crackle stand out more. What felt like new noise was just static I hadn’t noticed in the day.
Extra devices at night can cause interference.
When I turned on the humidifier and sound machine in my baby’s room, the monitor started buzzing. These devices send out small signals that clash with the monitor. If your baby monitor is making a crackling noise at night, try switching them off one by one. You’ll see which one is the problem.
Closed doors and thick walls can block the signal.
I used to shut the nursery door every night. That extra layer made the crackle worse. Radio signals don’t travel well through thick walls or doors. Leaving the door cracked or moving the parent unit closer cut the static for me.
Silence makes tiny sounds feel bigger.
During the day, the TV and kitchen sounds covered the monitor’s hiss. But at night, when the house was still, every small crackle felt louder. It was like hearing a tap drip in the dark—it felt huge even though it was small. Sometimes the issue isn’t the monitor, it’s the silence around it.
In short: if your baby monitor makes crackling noise while sleeping, it’s often because of night devices, blocked signals, or the silence making static more clear.
Baby Monitor Making High-Pitched or Clicking Noise
Short answer: a high-pitched sound is usually feedback, and clicking often comes from night vision turning on.
I remember the first time I heard a sharp squeal from my baby monitor. It was worse than the crackling. For a second, I thought the unit was broken. Later, I found out it was just feedback—like when a mic gets too close to a speaker.
High-pitched noise often means feedback.
When the parent unit and baby unit are too close, sound keeps bouncing between them. This creates that piercing squeal. The fix is simple—move the units apart or lower the volume a bit. If your baby monitor is making a high-pitched noise, space is usually the cure.
Clicking sounds are often harmless.
On my video monitor, I noticed a soft click every night near bedtime. At first, it scared me. Then I learned it was the infrared night vision turning on. Many monitors with cameras make this tiny sound when they switch modes. If your baby monitor is making a clicking noise, it’s usually not a fault but the camera adjusting.
Not every sound means trouble.
Crackling, squealing, and clicking come from different causes. Crackling is a weak signal. High-pitched squeals come from feedback. Clicking is often just night vision. Knowing the difference makes it less stressful—and much easier to fix.
In short: a baby monitor making high-pitched noise often needs more distance between units, while a baby monitor making a clicking noise is usually just the night vision switching on.
Do Baby Monitors Cause Interference? What I’ve Seen at Home
Short answer: yes, baby monitors can cause interference with Wi-Fi, phones, and even small devices.
I noticed this the first week I used my HelloBaby monitor. My Wi-Fi slowed down, and the sound from the monitor got fuzzy. Baby monitors and Wi-Fi clash because they often use the same radio bands.
Cordless phones made things worse. One night, while talking on the phone, my VTech monitor filled with static. Cordless phones and baby monitors interfere when they share the same frequency. Keeping them a few feet apart fixed it right away.
Even small machines, like humidifiers or sound machines, caused issues. My Babysense monitor once gave off a faint buzz each time the humidifier turned on. Extra signals from these devices can confuse the monitor.
I tested a few fixes that worked well. I changed the Wi-Fi channel, moved the monitor away from other gear, and kept it charged. You can cut interference by shifting Wi-Fi, adding space between devices, and using full power.
In short: baby monitors can cause interference, but small changes—like moving them, switching Wi-Fi channels, or charging fully—often clear the sound.
How I Fixed the Crackling on My Baby Monitor
Short answer: most crackling comes from weak power or poor setup.
The first thing I checked was the battery. My VTech monitor always got noisy when the charge was low. Once I plugged it in overnight, the static dropped. A full charge or stable outlet often makes the sound clear again.
Short answer: distance and walls can block the link.
I once had my HelloBaby monitor in the nursery at the far end of the house. The parent unit crackled like a radio out of tune. Moving it closer—or just cracking the nursery door—helped the sound flow without breaks.
Short answer: other devices can clash with baby monitors.
My router sat right next to the monitor, and every time the Wi-Fi got busy, the monitor buzzed. The same thing happened with the microwave. Shifting the monitor a few feet away cleared most of the fuzz.
Short answer: old software can add static.
When my Motorola monitor kept humming for no reason, I learned the firmware was outdated. A quick update fixed it. For Wi-Fi monitors, resetting or updating the software can stop interference.
Short answer: bad cables can create hiss.
One time, my Babysense monitor had a faint crackle even when fully charged. I swapped the power cord, and the noise was gone. Trying another outlet or cable is a simple way to rule out hardware issues.
If your monitor keeps making noise, upgrading to the Nanit Pro Baby Monitor gave me the peace of mind I needed
Short answer: sometimes it’s time to get help.
If none of these fixes work, it may not be your fault. I once sent in a faulty unit, and the company replaced it right away. If your baby monitor keeps making a crackling noise, contact support or think about upgrading to a new model.
In short: I fixed my crackling baby monitors by checking power, moving them closer, avoiding other devices, updating software, and testing cables. If all else fails, ask for support or consider a replacement.

Short answer: the Nanit Pro is the best premium pick for clear sound and smart tracking.
When I tested the Nanit Pro, it felt like having a second set of ears in the room. The sound came through clean, even when the Wi-Fi was busy. On top of that, its night vision was sharp, and motion alerts were spot on. If you want the best baby monitor with excellent night vision and health tracking, this one delivers peace of mind at a price.
Short answer: the VTech Audio Monitor (DECT 6.0) is the best budget choice.
I’ve used this one when I needed a simple, no-frills option. The DECT 6.0 tech blocks out Wi-Fi interference, so the sound stays crisp. It doesn’t have video or apps, but that’s why it works so well—no fuss, no static, just clear audio. If you ask me, it’s one of the best baby monitors for parents who just want reliable sound without extra gadgets.
Short answer: the Hello Baby Video Monitor is the best affordable video option.
This one surprised me. It’s budget-friendly but still gave me good night vision and a steady connection. The sound wasn’t as smooth as the Nanit, but it worked well once I kept it away from my Wi-Fi router. For parents looking for a video baby monitor with decent motion detection at a fair price, Hello Baby is worth it.
Short answer: the Sense-U Smart Monitor is the best for extra features.
I tried the Sense-U when I wanted more than just sound and video. It tracks breathing, room temp, and even alerts you if the baby rolls over. The sound quality was clear as long as the Wi-Fi was stable. If you like smart baby monitors with health tracking plus clear audio, this one gives you both.
In short: if you want premium features, go with Nanit Pro. For simple but clear audio, VTech DECT 6.0 is a gem. If you need an affordable video pick, Hello Baby works well. And if you want health tracking plus sound, Sense-U covers all bases.
FAQs About Baby Monitor Noise
Why does my baby monitor make static noise?
Short answer: static comes from weak signals or interference.
I remember sitting in my living room, hearing the hiss get louder as I walked farther from the nursery. The sound was not the monitor “breaking.” It was just the signal losing strength. Moving the parent unit closer or keeping it away from Wi-Fi gear often clears the static right away.
Why does my baby monitor sound distorted?
Short answer: distortion often means poor power or clashing signals.
When my VTech monitor sounded “robotic,” the battery was almost dead. Another time, it was sitting too close to my cordless phone, and the audio broke apart. Plugging it into stable power and shifting it a few feet made the voices clear again.
Can baby monitors pick up other signals?
Short answer: yes, older models sometimes catch stray signals.
One night, I thought I heard a neighbor’s TV through my monitor—it turned out the analog model was picking up a nearby signal. Most modern monitors use secure channels, so this is rare now. If yours does this, upgrading to a DECT or digital Wi-Fi monitor fixes the problem.
Why does my VTech monitor make a crackling sound?
Short answer: the battery is often the culprit.
My VTech got noisy once the battery aged—it hissed nonstop even in quiet rooms. Replacing the battery pack made a huge difference. Another quick fix was keeping it away from cordless phones, since both run on similar frequencies.
What should I do if my monitor makes noise only at night?
Short answer: silence makes the crackle stand out more.
At night, my monitor always seemed “worse.” Later, I learned the quiet house made the tiny hiss feel louder, and extra night gear—like humidifiers—added interference. Try turning off nearby devices, cracking the nursery door, or placing the parent unit a little closer.
In short: most baby monitor noise comes from weak power, blocked signals, or nearby devices. Fixes are usually simple—charge fully, move things apart, and keep the setup clean.Still struggling with low volume?

Final Thoughts
Short answer: crackling is common but fixable.
I know how stressful it feels when your baby monitor keeps making noise. It can make bedtime harder than it already is. The good news is, most crackling comes from small issues like weak power, blocked signals, or nearby devices. A few simple tweaks often bring the clear sound back.
Short answer: if fixes fail, it may be time to upgrade.
I’ve been there—trying every trick and still hearing that hiss in the background. At that point, I learned it wasn’t me. The monitor itself had limits. Modern models with DECT or Wi-Fi often cut out interference better. If you’ve tried it all and the sound won’t clear, switching to a newer unit may be the answer.
Short answer: peace of mind comes from trust in your monitor.
As a parent, I know sleep is precious. When my monitor finally worked without static, I felt like a weight had lifted. Clear audio doesn’t just mean less noise—it means more calm nights and steady confidence that your baby is safe. And that, in the end, is what matters most.
