The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
Here is a great bang-for-the-buck best baby monitor that has some great features. It is sold under two different brand names, one is Babysense, and the other is Smilism. We purchased both, and they were basically exactly the same other than the different logos. We're assuming they are the same company selling under two different brand names, but we can't be sure. Let's begin with the "bang" part of bang-for-the-buck. This baby monitor has a lot of good features, including two-way intercom, room temperature monitoring, "eco" mode that keeps the screen off until it hears your baby make a sound, remote zoom, and a few music (lullaby) options. It is also expandable up to 4 cameras, using the same base unit. From the base unit, you can cycle through which camera you want to view at any given time; you cannot view them all simultaneously on the same base unit (like picture-in-picture). We really liked the eco mode, and also liked that on the top of the unit there is a little flashing light to reassure you that it's on during eco mode, even though the screen is off. So there are a lot of great features here, especially for the low price of only about $75! That's right, only about $75, and each add-on camera is about $40. So there's a great deal for a nicely featured camera. What are the missing features? Well, the remote tilt and pan function was not included, so you have to position the camera the right way in your baby's room or you're out of luck in the middle of the night. Second, in our testing it took a bit too much time to cycle between each of the baby cameras: the screen would turn white and you need to wait several seconds for the other camera to show on the screen. This same white screen happens during start-up of the unit. We also weren't totally impressed by the range of the base unit on this Babysense video baby monitor. It works great if you're 1-2 rooms away, but if you go upstairs or several rooms away, the signal drops intermittently. Even with those little downfalls, this is a great budget pick for a well-featured baby video monitor with some good reliability, enough to put it up at this spot on our best-of list. Note that Babysense also makes a great new under-mattress movement monitor as well. We've been using it for 10 months now and it's still going strong with no issues. Interested?

There are two basic types: audio and video/audio. Some are analog, others are digital. All monitors operate within a selected radio frequency band to send sound from a baby's room to a receiver in another room. Each monitor consists of a transmitter (the child/nursery unit) and one or more receivers. Prices range from about $25 to $150 for audio monitors and about $80 to $300 for audio/video monitors.
