What is a Voice-Activated (VOX) Baby Monitor? 

There has always been a misinterpretation of what a voice-activated baby monitor is. Most of the time, we have been forced to think that voice-activated baby monitors are activated with a distinct voice. We might think they are things related to the Alexa device or Google Home, which is not the case. We have voice-activated smart-home tools that we might mistakenly connect to voice-activated baby monitors.

With the smart-home type of devices at home, you have a chance of controlling almost everything. Voice-activated baby monitors cannot be controlled by the parent. It goes on and off according to the voice and sounds the baby makes in the nursery. This implies that when the baby is sleeping, the device minimizes its monitoring level. It ideally listens to any sound that is when it becomes active. When the device detects the audio and sometimes video, it is relayed to the equipment that is monitoring.

Why voice-activated monitor is Important ?

The term VOX simply means that it is a voice-activated baby monitor. It, therefore, implies that when the baby is asleep, the screen display goes in the sleeping mode and stops the transmission. The microphone, however, remains active, and when the sound from the baby is detected, the transmission automatically resumes. There is no need to use a button to activate it as it is an automatic device.

There are two benefits a parent will benefit from a gadget that has VOX on it. First is that it is an automatic feature that doesn’t need your presence. It will automatically pick the sound from the baby when it cries, fusses, or babbles and alerts you on the parent unit.

Second is that after 10 seconds, the baby monitor’s screen will go off when there is no sound detected. This is good because it saves the battery life and that the light doesn’t destroy the baby while sleeping. It only comes on when the sound is detected so that the parent can attend to the baby when necessary.

The parent, therefore, has ample time and a quiet night knowing that he/she will be signaled when the baby is awake. The parent, therefore, has a modest time and a calm night knowing that he/she will be signaled when the baby is awake. You can appreciate the benefit of the VOX feature on the baby monitor when you adjust the microphone sensitivity. The device can be adapted regarding the age of the baby or ambient sound.

Are Voice-Activated Baby Monitors Safe ?

Most parents globally have appreciated and embraced the use of voice-activated baby monitors. The mentioned baby monitors are becoming more and more popular. New parents who come across such devices might wonder how they work and, if at all, are safe to be used in monitoring their babies.

To begin with, voice-activated baby monitors are considered to be safe to monitor young ones in our homes. They are regarded as reliable and useful because they don’t track the activities of the baby throughout, but only when there is a need. By this means, the little one is not exposed to EMF radiation that is alleged to cause health problems to the baby. It has been discovered that the skull of the baby is thinner compared to the adult, and when exposed to radiation, the baby is at high risk. Also, the parent has a peace of mind at night, knowing that he/she can respond to the needs of the baby when there is sound detection.

Before you can start using the device, a parent who is not familiar with the function has to familiarize yourself with how it operates. It is, however, not different from other baby monitors only that it has VOX mode as an extra feature.

Are Voice-Activated Baby Monitors the Best Choice ?

Most experts have recommended the use of voice-activated baby monitors. However, whether this device is the best choice or not partly depends on the needs of the parent, the circumstances, and the safety considerations you value most.

Dr. Magda Havas, a leading researcher dealing with EMF radiation dangers, especially when it comes to the impact they have on babies, and little ones have an opinion on baby monitors. Dr. Havas suggests that the base station transmitter of the baby monitor should be voice-activated. The transmission should be transmitted only when there is sound from the baby. This reduces exposure to microwaves and the rate at which the EMF can be transferred.

Dr. Havas says that there is confusion when it comes to voice-activation mode. It is said that the activation mode is not the same on all monitors. Dr. Havas says that some of the radiation broadcasted cuts ‘squelch’ in the receiver. With this information at hand, there is a conclusion that has to be made. According to Dr. Havas, avoiding monitoring devices is a better option, but it depends on whether the monitoring needs outweigh the radiation or the vise vasa. The decision, therefore, lies in the hands of the parent.

VOX for Video Baby Monitors

VOX feature on video baby monitors is fundamentally important because it helps the monitor stop continuous transmission. With VOX Mode, the transfer will be effected once the baby is awake. The screen display will otherwise remain in the sleep mode and will only transmit video when it is activated.

The parent, therefore, will have a peaceful and quiet night and will attend to the call of the baby when the baby wakes up and needs attention. The baby also will not be interrupted from sleep with light that comes from the monitor. It also helps in saving the video monitor battery for an extended period.

VOX for Walkie-Talkies with Baby Monitor Mode

Some models of walkie-talkie have been designed to have a baby monitor mode. When this feature is activated, the walkie-talkie will work in the same way as the baby monitor. In this mode, the batteries can be drained 5x faster compared to the average. When it has a VOX feature, the battery life can be extended for a reasonable period. The VOX feature keeps the walkie-talkie device in sleep mode with the microphone on. When sound from the baby is picked, the device then becomes active and transmits the information. It is a suitable device because it covers the most extensive range compared to the average baby monitoring device.

What to Look for When Buying a VOX Baby Monitor

VOX Mode vs. Eco Mode in Baby Monitors

Baby monitors that have VOX features allow the device to function when it picks the sound from the baby. This means that when the baby is sleeping, and there is no sound in the crib or baby’s room, there will be no transmission of audio or video feed to the parent unit.

Eco mode is a similar feature to the VOX mode. This is because the two elements are activated by sound from the baby’s room or crib. A baby monitor with Eco mode will not transmit sound and movement signals made by the baby. Other elements can be activated when the Eco mode is on such as temperature, movement, sound, and so on.

Importance of VOX Mode

The importance of VOX mode in baby monitors is to reduce the chances of emitting radiation to the little ones. Wireless digital devices are known to emit some emissions when they are transmitting both audio and video feed. The radiation has been discovered to be harmful to both the parent and the baby.

VOX and Non-VOX Baby Monitor Radiations

There is a difference in radiation transmission between baby monitors with VOX and those without the VOX mode feature. Non-VOX baby monitors have higher radiation emission than the VOX ones. Non-VOX emits five times more than VOX baby monitors. Parents who have not used the VOX baby monitors might be confused with this, while those who are familiar appreciate the VOX mode feature.

Do voice activated Baby Monitors Emit Less EMF Radiations?

As to whether the voice activated monitors emit less EMF radiations is a matter of making comparisons of those with VOX and those without when we compare the two baby monitors, the variations between them in terms of EMF radiation emission is not significant enough to say that there is less EMF radiations emission.

VOX Mode in Baby Monitors

It is easy to turn on and off the VOX mode in baby monitor devices. When you turn on the VOX Mode in the baby monitor, there will be a transmission of sound and video to the parent unit from the baby’s room. This is only when the sound is activated, and when it is turned off, the baby monitor will behave like that without the VOX feature.

Adjusting Sensitivity of a Voice Activated Baby Monitor

In some instances, you will come across baby monitors that let you adjust the microphone sensitivity. You can change its sensitivity so that it becomes so sensitive to all sounds that activate recordings and transmissions. Before you can make any adjustments to the VOX, it is necessary to review default settings. Playing music in the room of the baby can help you set volume levels and see the sensitivity. The microphone is very sensitive if the first volume level makes the baby monitor active.

There are different noises made by different babies depending on age. It is worthwhile noting the sound your baby makes to determine a sound level that is suitable to activate the device.

Final Notes

If you purpose to buy a baby monitor to keep an eye on your baby, a baby monitor with the VOX feature should always be on the list of factors to consider before buying it. As earlier mentioned in this review, a baby monitor with the VOX feature has a lot of benefits. A baby monitor essentially helps the parent have peace of mind during the day and a peaceful and quiet night.

With the VOX mode on, you can reduce EMF radiation exposure to the baby. This is because the device becomes active only when it detects a sound from the baby and transmits sound or video feed to the parent unit.
