How far away baby's monitor can be from the parent unit is what determines a product's range. While many manufacturers offer a "line of sight" range to describe a monitor's range, it is not a good indication of how well it will work in your home with walls and interference. It doesn't matter how much you like a specific model or brand, if it doesn't work in your house, it simply isn't going to work. We tested both indoor range and open field tests to provide the best information, but remember that the values inside your home matter more than those in an open field, unless of course, you are leaving a baby alone in an open field (which we don't recommend).

Still, the video delivered by the Arlo Baby was crystal clear, even at night. A whole host of sensors — temperature, humidity and air quality — can alert you to any change in your kid's room. The versatile app can send you notifications however you want, and we were particularly impressed by an Always Listening mode that streamed audio to our smartphone.
When shopping for a video monitor, note that you'll pay a substantial premium over audio-only monitors, which cost around $30 to $50. You'll need to decide if the extra money for video viewing is worth it, though parents may appreciate the ability to glance at a smartphone app or handheld monitor to visually check in on their sleeping child instead of opening a door and potentially waking up their baby.

If initial impressions mean anything, this is definitely one of the biggest bang-for-the-buck baby monitors on the market. It has some fantastic features, and is offered at a great price point at around $70! Here are some of the best features: first, it has very clear daytime video and crystal clear sound. Using 2.4Ghz communications, like most others on this list, it does a great job connecting, staying connected, and providing superb sound quality. It also is expandable with additional cameras - up to 4 additional cameras to be exact, which means you can really get one of these everywhere. Need one in the playroom, nursery, by the bassinet? Having up to 4 cameras connected is awesome, and the base station provides the easy ability to switch which camera you're looking at. Of course, it only comes with one out of the box, but you can buy extra cameras for about $40 each. We also liked that there is no complicated setup like with some of the IP cameras on this list, which means that there is no connecting to your internet router, or trying to get a phone app to connect. Of course, that also means you can only watch from the base station, not on your phone. About that base station. You can control whether you want digital video and sound, or sound only, and you can also remotely zoom in on your baby as needed (only 2 zoom levels though), but you cannot remotely pan or tilt the camera. There is a 2-way intercom (twoway talk) so you can talk to baby, or play one of the included lullabies. With the screen on, we were able to get the base station's battery to last for about 7 hours, and with just sound the battery lasted for about 11 hours. So definitely long enough for nap times during the day! Like many of the other ones on this list, you can put it into standby mode and have it voice activate automatically when the camera's microphone hears something in the room (like a fussy baby). We thought this feature worked really well and wasn't overly-sensitive and false alarming all night, which could get really annoying. So there are a lot of things to love about this baby video monitor. With such a low price, the feature list is obviously limited. We also thought the nighttime video quality really left something to be desired. We kept trying to increase the brightness to help, but it still was pretty poor relative to other units on this list. Finally, when we first reviewed this system we purchased 3 of them. After 1.5 years, only 1 of them is still working perfectly, 1 of them is a bit glitchy from time to time, and the other one had a screen failure. So we see some reliability and consistency issues with these baby video monitors, and that's the primary reason that it's not higher up on our list. In any event, we do recommend this camera, especially given the overall bang for the buck. But given how cheap it is, don't expect any miracles, or to be buying something to last you until you have grandchildren!
Monitors for babies should have good video images that are clear and true to life, but they should also have quality sound that is easy to hear and clear enough that parents can quickly decide if they need to look at the viewing screen, go back to sleep, or get running to the nursery. So while you might consider video quality to be the most important metric for this kind of product, we rated both video and sound equally because, without one, the other doesn't much matter. If the sound is muffled, difficult to decipher, or not loud enough, then parents might miss baby's cries. If sound activation or thresholds for background noise don't work as described, then parents might lose sleep listening to a loud monitor. However, once alerted, you need a clear view of baby with enough details to determine baby's needs, day or night, or the video style monitor isn't much better than a sound only monitor.
Beyond security, Wi-Fi monitors have other disadvantages. In our tests, connectivity was more of an issue with Wi-Fi monitors than it was with RF monitors. We tested our Wi-Fi monitors on two separate routers and consistently had problems—we’d often lose the connection some time in the night and not even realize that the monitor had disconnected until morning. This happened with all three Wi-Fi models we tested. We never really felt confident relying on any of the connected monitors overnight, despite the fact that the modem and router were literally on the other side of a wall from the monitor. Other owners (like this one) have had the same issues.

If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
