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.
Another Summer Infant baby monitor option, not quite as great as most others on this list, but definitely a trusted and reliable model and one of the best baby monitors available on the market this year. In our testing, one of the first things we noticed about this baby monitor was the sleek mobile-phone-size touch-screen reminiscent of the older iPhones. What's nice about this form factor is that it slips easily into your pocket like a mobile phone. Many of the others need to be clipped to your belt or waist, as they are quite a bit too thick or large for the pocket. The actual video display is modestly sized, coming in at 3.5" diagonal viewing area. This is the same size as the Infant Optics model. And it has some great features. It has remote pan (side-to-side adjust), tilt (up/down adjust), and zooming capability. Two-way audio communication so you can hear baby, and talk back to baby (maybe sing a lullaby, or whisper something to help soothe your baby). The system is also expandable to up to 4 cameras. Each additional camera is about $99, and you can place them in various locations around the home and toggle between them with the video unit. In our tests, the battery lasted about 4-5 hours when off the charger (and being used), and charged back to full capacity in only a couple hours. We didn't think the picture quality was as good as most other options on this list, nor was the sound. We also hooked it up to multiple cameras and used the "scan" feature which rotated through the various cameras once every 8 seconds. In our opinion, it took a bit too long to switch to a particular camera. It was also pretty loud when we remotely adjusted the pan/tilt of the camera. Also, it's worth noting that the pan feature doesn't seem to work when it's zoomed in. So overall, you're getting a good form factor, a reliable camera, but not the best image quality. For about $150, we think you could do better with one of our higher-rated options!
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.
This monitor offers lots of convenient features. Don’t have the best view of your baby? Use the monitor to remotely pan, tilt or zoom the camera without having to go back into the nursery. Fussy baby? Press a button to play lullabies. Need the camera to move from your bedroom to the nursery? No problem: this freestanding monitor can be set on top of a dresser or grip onto shelves and brackets. You can also unplug it and use it in another room for up to three hours on a single charge. And there’s a room temperature display. But the most impressive feature is its 1,000-foot range—the highest of all cameras on this list. That means you can hear your little one’s every chirp even if you’re hanging out in your backyard.
