Everything you need to know about the Baby Crying Detector aka monitor

By  | 

A baby crying detector, also known as a baby monitor or baby alarm, is a device used to monitor a baby from a remote location. These gadgets alert parents and caregivers when their baby is disturbed or awakened from sleep while they are out of immediate hearing distance from their child.

Whether they are hungry or need a diaper change, babies cry to communicate their needs. Baby crying detectors will help you take that much-needed shut-eye in between cries. The more confident you are in your detector’s capability to alert you, the better your chances of having restful, anxiety-free sleep. This is useful for new parents who are usually more anxious and sleep-deprived.

When Were They Invented?

The world’s first baby crying detector was designed by Japanese-American sculptor Isamu Noguchi in 1937. The president of Zenith Radio Corporation, a major American radio manufacturer, commissioned him to create the device so that he could monitor his daughter while on his yacht. The gadget was called the Radio Nurse and featured a sleek industrial design molded from bakelite, an early form of plastic.

The first devices, like the Radio Nurse, were designed to be simple radio-systems that transmitted sound. Today, the baby monitor has evolved from a sound-only device into a more multi-faceted gadget with sophisticated features. This article will teach you all you need to know about baby monitoring solutions and what  you need to consider if you decide to buy one for your baby.

How to Choose The Best Monitor

There are many detectors out there so which one is the best for you and your baby? There is no ultimate answer to this question because it all depends on your personal needs, budget and other concerns. The following information will help you to narrow down your choices and make the choice yourself.

The Basic Types of Devices

There are three basic types which are based on their capabilities: sound baby monitors, video baby monitors and the movement baby monitor. The following are the descriptions and usefulness of the most basic features of baby monitors.

1.Sound baby monitor – Sound is the most basic feature of any detector and probably the one that you will rely on the most. This type lets you install a speaker in your child’s room which will transmit sound to a receiver. Sound baby monitors alert you whenever your baby awakens from sleep and needs attention or if there are any peculiar noises in the room.

Most if not all types of baby monitors will feature a sound capability. Without this feature, devices will be useless especially when you are sleeping or doing something outside your baby’s room.

2.Video baby monitor – Video baby detectors give you the added functionality of being able to visually monitor your baby while in another part of the house. They include a small camera which you install in your baby’s nursery. Videos are very practical for checking what is going on in the baby’s room especially if there are no sounds to alert you.

Some models of video monitors include features like night vision and zooming in on details. Video baby detectors are also a good option if you need to look after several children and monitor more than one place at the same time.

3.Movement baby monitor – Motion sensing capability is one of the newest features for detectors. Movement baby monitors go beyond sound and video to alert you of any changes in baby’s movements.

Motion sensing monitors work by installing movement-sensing pads under the mattress of the crib. The pad’s motion sensors are designed to be sensitive enough to notice small changes in a baby’s movements while they sleep. For instance, if your baby suddenly stops moving for a certain period of time, an alarm will sound to alert you.

This feature will be of interest to parents caring for their infants in the first six months because this is the time when the risk of Sudden Infant Death Syndrome and sleep-related deaths are particularly high.

Other Important Specifications to Consider

Range, clarity and interference will affect the performance and functionality of your baby crying detector. Here are some of the things you need to know about these specifications:

1.Range – It is worth noting that many manufacturers use open fields to test their maximum range specifications. This is potentially misleading because baby monitors are used indoors with walls and other obstructions so don’t take the indicated range at face value.

Test the product indoors first before buying and think about your home interiors when you do this. Consider the thickness of walls and other items that might interfere with the capability of the baby monitor to transmit a signal.

2.Clarity – Clarity refers to the quality of the signal transmitted by your baby monitor. Your baby’s cries should be the primary sound that your device picks up but it also helps to hear other sounds in the room very clearly. Good sound quality ensures that you don’t hear any loud static noises that could overwhelm the sounds your infant makes.

3.Interference – Baby crying detectors suffer from two main signal interference. Obstructions between the parent unit and the baby unit are the first cause of signal interference. The second are other radio frequency devices present near your baby crying detector. These devices include wireless telephones and other baby monitors.

To minimize the amount of interference, consider the type of transmission used by your device. These are discussed below.

Mode of Transmission

Baby crying detectors are differentiated by their modes of transmitting signals. These are:

1.Analog – the earliest baby monitors used analog transmissions. The biggest downside of analog transmissions is that they can pick up sounds from other monitors and even radios and your signal can be picked up as well. Newer transmission types are fast overtaking analog-type baby monitors but they are generally the cheapest available.

2.Digital – digital baby monitors offer clearer and better quality transmissions compared to analog types. If you live in a densely populated area or live close to your neighbors, a digital type will be a better option because it is less susceptible to interference.

Important Safety Reminders

  • Baby crying detectors should never be considered a substitute for parental care or supervision.
  • Baby crying detectors have not been tested and proven to prevent sudden infant death syndrome (SIDS).
  • If the baby crying detector comes with wires, make sure it is not within reach of your baby to avoid strangulation or electrocution.
  • To avoid prevent electric shocks, never place the baby crying detector in areas with water or where it could potentially get wet.
  • Many advanced baby crying detector feature internet connectivity which exposes it to the risk of hacking. Make sure to set up strong passwords for this type of device and update passwords regularly.

When choosing the best baby crying detector, make sure the device meets your primary needs and concerns. Take extra time to read and research about product reviews and make comparisons online. If buying from a physical baby care store, make sure to ask questions from the salesperson and request a demo.
