This is a light or beeping sound that lets you know that you've reached the monitor's range limit. If you have a model without this feature, static might be the only indication that you're out of range. (A monitor's range can vary due to your home's size, its construction materials, and other factors.) The greater the range, the better--especially if you plan to take your monitor outside.
We wanted to recommend an inexpensive video monitor, but their flaws were so significant that we decided we’d rather spend less on a quality audio-only monitor like the VTech DM221. This is a well-reviewed best seller in the category, and it has crisp sound and better talk-back functionality than the best video monitors we found, as well as a longer range and better battery life than our video picks. It easily beats out its audio-only competitors for various basic reasons like being cordless, rechargeable, or less expensive.
The range of a product can make or break whether or not you can use certain options in your home. Depending on the distance from your room to the baby's nursery and the construction of your home or interfering appliances, you could be limited in your options of what will work for you. If your house is large or has more than a handful of walls between the two room, you'll be stuck with a Wi-Fi option only (assuming you have Internet). If your home is smaller or has fewer walls, then you'll have more options. Many of the wearable movement choices work in the baby's room and are not dependant on communicating with a parent device. However, if your room is out of earshot, then you'll never hear the alarm go off making the unit virtually useless without a sound monitoring addition. Choose your product carefully if you think the range will be an issue and purchase from retailers like Amazon that have a generous return policy. Also, don't let it sit in the box, try it out right away and send it back immediately if it doesn't work in your space. Do not rely on the manufacturer's range claim, as we have found these claims to be wildly inaccurate for many brands during our testing.
Range, clarity and minimal interference are factors that should be considered when you're selecting a device for baby monitoring. Range especially is something you'll want to verify/test yourself once you get any of the monitors home because they are often rated in a line-of-sight situation, but rarely used that way. Depending on the monitor type, whole home Wi-Fi can be a great option to keep your monitor wirelessly connected just about anywhere in your home. With video baby monitors, you may also want to consider getting one with the ability to record, while a low battery indicator, volume control, temperature display, and a music player may also be important convenience factors for you. Privacy can also be a consideration. Digital monitors are more difficult to hack than analog monitors because their transmissions are encoded.
For roughly a third of the price of our pick, the VTech is far more affordable. Losing video is a major sacrifice, of course, and we’re certain most parents looking for a first monitor will prefer being able to do a visual check-in on a baby. Budget advantages aside, we could see this being best for parents of toddlers who are considering replacing a failing monitor, and who know they will likely use a monitor only at night as a way to hear a kid crying out from a distant bedroom. Many reviewers have also found it useful as a way for adults to communicate, especially for caretakers who need to be able to hear when adults with mobility or medical issues need help in another room.
This monitor is known for its zoom lens, included in the box, that lets you see your baby up close even if you have to position it farther away from the crib. You can use the monitor to remotely adjust the camera, and you don’t have to worry about plugging the monitor in overnight—it can sit on your nightstand for up to 10 hours in the power-saving mode (similar to sleep mode on your computer, but it still provides sound monitoring while the display is off) and up to six hours with the display screen constantly on.
