The air-quality feature monitors Volatile Organic Compounds (VOC) levels. These are organic chemicals like acetone or benzene. The EPA says these chemicals are found in paints, paint strippers, aerosols, cleaners, disinfectants, solvents, etc and can cause serious health issues including eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system and even cancer. The Home will alert you to high VOC levels, which indicates it may be time to open a window or increase air circulation in your house. It does not monitor carbon monoxide.
The Samsung SEW-3043W BrightView HD's primary advantages over our pick are a larger, crisper display and a sleeker-looking package overall. But it is not our pick because its main disadvantage—a slow and unresponsive touchscreen—is such an annoying flaw that we're sure you'd prefer our pick's reliable tactile controls. The Samsung also falls short of our pick on battery life and because of other long-term battery and charging issues. On many other measures, the two monitors came out more or less even.
With more than 24,000 Amazon reviewers giving this monitor a near five-star rating, we’re proud to include the Infant Optics DXR-8 video baby monitor on our list of best baby monitors. Parents rave about its crystal-clear picture in both light and darkness, and the interchangeable wide-angle lens for larger viewing areas (sold separately). Not only that, the DXR-8 has the ability to pan and zoom across baby’s room without parents having to enter the room and move or adjust the camera. We think these features make the Infant Optics DXR-8 the best video baby monitor.
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.
