Motion and audio sensors: In the old days, parents were forced to endure a consistent ambient hiss from their audio monitors while they listened for their child’s stirrings or cries. Mercifully, many modern baby monitors will stay in “quiet mode” until they detect motion and/or sound, which will trigger an alert, such as activating the handheld video display or pushing a notification to your smartphone.
The Nest boasts some impressive hardware specs, such as true 1080p/30fps video and a 3-megapixel camera sensor. Setting up the Nest Cam specifically to look in on a 2-year-old at night, we found the video quality on Nest's camera to be sharper and more detailed than on any baby video monitor we tested. The Nest Cam includes push-to-talk features as well as alerts triggered by motion or sounds. And when your child is past the age when you need a nighttime monitor, you can repurpose the Nest Cam to check in on other parts of your home.
My husband and I had been using a spare phone and $4 baby monitor app for the past 5 months. We co-slept and only needed the monitor during the day and so sound was all that was necessary. Now that our baby is sleeping in the crib I wanted to be able to see her if she rolls over or wakes. We also wanted to be able to check the temperature of the nursery as it's usually way off from the rest of our house. After reading reviews, we decided to give the Hello Baby monitor a try. It hasn't been that long but I'm really impressed with the quality of the product for the price! So easy to use and really great picture quality especially the two way audio which we use quite a bit! The screen itself is bright and vibrant.
* Guest Accounts: need to allow guest accounts for grandparents, but absolutely need the ability to turn OFF the microphone for those accounts. The camera is only in the baby's room, but the microphone extends as far as sound travels, and you probably don't want your mother-in-law listening to every discussion in your home. This is a HUGE security feature that is a requirement for anything with guest accounts
