7 Factors to Consider When Buying a Baby Monitor

For many families, allowing a baby to sleep in a room alone is a blessing in that it allows the baby to sleep without interference, and allows parents to sleep or relax without waking the baby. Of course, it is extremely important to make certain that a baby is continually monitored in order to determine if the baby is safe or in need of anything. The best way to make sure that a baby is monitored is by using the aptly named baby monitor. Baby monitors come in all shapes and sizes, many of which are available in electronics stores or on eBay. When buying a baby monitor, it is important to find not only the one which that benefits an individual family's unique circumstances, but one which is most affordable and effective as well. Along with those factors there are several others that should be taken into consideration when buying a baby monitor for your nursery. These factors include monitor range, monitor display, signal type, monitor security, portability, multi-room monitors, and advanced monitor features.

1. Monitor Range

While nearly all contemporary monitors are wireless, the range of their wireless capabilities may in fact vary. This is an important factor to consider for families who live in larger homes or who routinely engage in activities in a room far away from where their child is sleeping. For the most part, a standard monitor is able to function anywhere within a standard home, although for taking it outside into a yard or into a garage, a monitor with extended range may be necessary.


For the most part, a baby monitor's range is determined by the signal frequency. Basic models make use of a signal measured at 49 Megahertz. Higher frequencies have a higher range, but interference is possible when baby monitors hit the 900 Megahertz range. This is because many mobile phones also use signals with this frequency. Many newer baby monitors use a much higher frequency, in the Gigahertz range in order to avoid interference. This has the added benefit of greatly increasing range.

2. Baby Monitor Display

Like all technology, baby monitor technology is constantly evolving, meaning that monitors with advanced technologies are becoming less expensive. For the most part, however, there are two main types of baby monitors: audio and video. Audio monitors only allow parents to hear their child. For the most part, this provides an accurate sense of whether or not a baby is sleeping, or if it is in any type of distress. Video monitors are more expensive, but allow parents to view their baby as well as hear them. Video monitors make use of infrared technology so lights do not need to be on for the video to be clear.

3. Signal Type

For a long time, baby monitors were notorious for either causing, or being subject to, interference from other devices, including telephones, radios, and even televisions. This is because older models of baby monitors used an analogue signal , which was transmitted via radio waves. One side effect of an analogue monitor is that anyone who is in range can receive and listen to the signal. The combat these negative effects, most newer baby monitors utilise a digital signal. A digital signal is one in which the sound or video signal is transformed into a data stream. Not only does this data stream not cause interference but it is less likely to be subject to interference.

4. Monitor Security

While digital monitor signals are generally safe from prying eyes, there are other methods that can be put into place in an effort to increase security. This is of particular importance to those who have video monitors, and as parents are understandably uncomfortable with strangers being able to view their sleeping children. Monitor security can come in several forms. One is known as DECT (Digitally Enhanced Cordless Communications). DECT technology basically encrypts the signal sent from the transmitter so that it can only be understood by the receiver. This makes it virtually impossible for the signal to be viewed by a third party. A second form of monitor security is known as a digital lock that keeps videos from being seen by other people.

5. Portability

For many parents, they are busy enough that staying in one room with a baby monitor is difficult. For this reason, there are portable receivers that can be carried around either in a pocket or on a belt. Many portable receivers even have a belt clip for this purpose. For obvious reasons, these receivers are designed to run on batteries so that power cords do not become a safety hazard or limit portability. For the most part, it is audio monitors that are designed for portability, as a video monitor worn on a belt can not easily be viewed.

6. Multi-Room Monitoring

Parents who want to monitor multiple children, or children in multiple rooms, can take advantage of multi-room monitors. Multi-room monitors are a variety of video monitor that either has multiple screens corresponding to different rooms, or a single screen that is divided into multiple portions in order to allow for multiple viewing. Obviously, either system requires that multiple transmitters be set up in multiple rooms.

7. Advanced Monitor Features

Monitors can come with a number of advanced features that set high-end baby monitors apart from simple devices. Most of these features are designed to allow parents to either better access footage or audio of their child, or to better determine whether or not their child is in distress.

Talk Back Feature

For most parents, it is important to be able to respond to their children when they are in distress, and for this reason, there are some baby monitors that have a talk back feature that allows parents to do so. For the most part, this involves pressing a button or flipping a switch so that children can only hear their parents when the parent wishes it.

Sound Activated Light

In some cases, parents are unable to hear if their child is in distress, due to medical issues or an abundance of other noise. In such situations it may be helpful to purchase a monitor with a sound activated light that actually lights up when the baby makes noise. This can be extremely helpful where the sound of a crying baby might be a distraction such as during a party or when vacuuming.

Motion Sensors

Rather than tell a parent when their child is moving, certain baby monitors are equipped with technology that notifies a parent when their child has not moved within a certain time frame. This can help parents who are worried about any illness or breathing problems with their infant.


In many places, blankets are considered to be a safety hazard for infants. For this reason, many parents utilise alternative heating methods to make certain that their baby is warm enough. To complement this, some baby monitors are equipped with thermometers that make it possible for parents to read the temperature of their child's room without ever having to go inside.

Buying a Baby Monitor on eBay

For parents who want to explore the many kinds of baby monitors available, eBay is a good choice as sellers from around the world list a wide selection of items. The key to finding the ideal baby monitor is to use specific keywords to guide your search. Since a general search for baby monitors can be conducted by simply entering the term, ' baby monitor'' into the search bar on the eBay home page, a more detailed search term provides a list of very specific items and features. This can allow you to compare prices and features in order to find the very best option for your family.

Evaluate Each Item Carefully

All items sold on eBay have a product description that gives buyers a better understanding of each item's condition. It is important when making a purchase to read this description, especially for used items, in order to ascertain if the item functions properly. In a similar vein, it is also important to read seller feedback in order to make an informed decision about each item.


A baby monitor is a perfect of example of how technology can make life safer for the most vulnerable people of all, infants. With a baby monitor, parents can let their baby sleep peacefully in an enclosed room and keep track of their health and safety without disturbing them. The first baby monitors were designed only to provide a means to listen to a baby, but newer monitors incorporate video and even wireless connectivity for a better understanding of what is going on in an infant's room. Along with the ability to provide video coverage of an infant, many monitors also have other features, such as enhanced security or lights that appear when an infant is making noise. All of these features should be evaluated when purchasing a baby monitor, along with factors such as range, signal frequency, and whether or not it is helpful to have a monitor that extends across multiple rooms. A careful study of these factors make it possible for parents or others to buy the baby monitor that best fits their needs.
