VOX on a baby monitor stands for Voice Operated Exchange. It's a smart feature that activates the monitor only when significant sound is detected, conserving battery life and reducing continuous EMF radiation.

Baby monitors allow us to keep an eye (and ear) on our little ones without having to be in the baby's room 24/7. But did you know there's a feature on video baby monitors that can make your life even easier? It's called VOX mode, and it's here to change your parenting game.

What is VOX Mode?

VOX stands for Voice Activated Exchange or Voice Activated Transmission. All fancy terms aside, it's a feature that makes your baby monitor smarter.

Instead of transmitting sounds continuously, the baby monitor with VOX mode only activates when significant sound is detected from the baby unit. This means your monitor won't drain its battery by transmitting the sound of every little rustle in the room.

Thanks to VOX mode, the parent unit stays silent and conserves battery life until your newborn baby decides it's time for attention. The moment your baby starts crying or making noises, the VOX mode kicks in, and the parent unit springs to life, notifying you immediately.

VOX mode is different from regular sound-activated mode, which only turns on the speaker when there is noise. VOX mode also turns on the screen, so you can see your baby as well as hear them.

Real-Time Monitoring with VOX Mode

One of the main benefits of VOX mode is real-time monitoring. With a video baby monitor that has VOX mode, you can keep tabs on your little one without having to constantly check the parent unit. The VOX mode ensures that you get instant updates whenever your baby makes significant noise.

This feature is especially helpful during the night. When your baby is sleeping, and the house is quiet, the last thing you want is the continuous white noise coming from the monitor. With VOX mode, the monitor goes into sleep mode, but don't worry, the microphone is still active, ready to pick up any significant sounds from your baby.

Additionally, VOX mode can contribute to a more peaceful environment for the baby and parents. The monitor will be silent until the baby makes a significant noise, eliminating the constant white noise that can come from the parent unit when the monitor is on full time.

VOX Mode and EMF Radiation

Besides saving battery life and providing real-time updates, VOX mode also reduces EMF radiation. How so? By minimizing the continuous transmission of audio and video signals from the baby monitor camera.

Traditional baby monitors continuously transmit audio and/or video signals from the baby's room to the parent unit. This continuous transmission means the device is constantly emitting some level of EMF radiation. VOX mode changes this dynamic.

This means that when the baby camera is not in use, the VOX mode cuts off the transmission, thus reducing your baby's exposure to EMF radiation.

Adjusting the Sensitivity of VOX Mode

Now, you might be wondering, "What if my baby makes very soft noises, or what if the baby unit is a bit far from my baby's crib?" Well, most VOX baby monitors have an adjustable sensitivity setting. You can set it to high if your baby is a soft cooer or set it to low if you've got a future rock star on your hands.

Some baby monitors even offer multiple sensitivity levels. You can experiment with different levels to see which one works best for you and your baby.

To test the sensitivity level, you could try playing a crying baby sound in the room and adjust the VOX sensitivity level to trigger at that volume level.

Advantages of a VOX Baby Monitor

VOX mode on a baby monitor certainly has its advantages. Here are some of the additional benefits that come with using VOX mode:

Energy Efficiency

As VOX mode only activates the baby monitor when significant noise is detected, it can save a substantial amount of energy. This is because the device isn't continuously running, thus reducing its overall power consumption.

Less Disturbance

With VOX mode, parents are not disturbed by constant white noise or minor sounds. The monitor only activates for notable noises, allowing parents to have undisturbed sleep or concentrate on other tasks without being distracted by insignificant sounds.

Increased Longevity

Since the baby monitor isn't in constant use when in VOX mode, this can potentially extend the life of the device. Less continuous operation means less wear and tear on the monitor's components, which could result in a longer lifespan for the device.


Some parents may feel more comfortable knowing the monitor isn't always on, transmitting everything that happens in the baby's room. VOX mode ensures the monitor only turns on when it needs to, offering an added layer of privacy.


VOX mode can make parents more alert to their baby's needs. Because the monitor is quiet until the baby makes a significant sound, parents might respond more quickly when they do hear something from the monitor.


Over time, the energy savings from using VOX mode can add up, making it a cost-effective option. The potential for increased longevity could also save money in the long run, as the monitor may not need to be replaced as quickly.


Many VOX mode monitors allow you to adjust the sensitivity settings, letting you customize when the monitor will be activated. For example, if your baby is a heavy sleeper and rarely makes noise, you can set the sensitivity higher so that the monitor will only activate for louder noises.

Wrapping Up

So, why have VOX on a baby monitor? Because it's a game-changer. It saves battery life, provides real-time updates, reduces radiation, and can be fine-tuned to match your baby's noise level.

It's a feature that combines practicality, efficiency, and convenience, making it a valuable addition to any baby monitor.
