The most important thing to look for in all kinds of baby monitors is audio quality. Regardless of whether you want a video-based baby monitor or not, you need clear audio so you can hear your baby properly. You'll also want one with sound activation so that you don't have to listen to white noise 90% of the time. With sound activation, you'll only hear the noises from your baby's room when there's something important to hear.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
Wi-fi baby monitors are the latest innovation in high-tech baby gear, and they’re super convenient. A baby monitor with wi-fi allows you to connect anywhere that has Internet service or Bluetooth capability, and the monitor can often be controlled remotely using a smartphone or computer. This functionality makes the wi-fi baby monitor great for travelling (unless you’re heading to a remote location). Safety tip: No matter what connection you use, be sure that it’s a secure connection in order to prevent your monitor from being hacked.
When shopping for baby monitor, try to choose a product that offers both quality and security. For best results, opt for a model that offers both audio and video capabilities. You should be able to see and hear your baby in real time and also talk back to them as needed. Baby monitors can vary dramatically in quality, but today's models offer stunning HD video that ensures you can see your baby's surroundings with crystal clarity. Purchase the best quality you can afford, and enjoy the peace of mind that comes from knowing that your baby is closely within reach.
Most dual monitors come with split- or even quad-screen viewing, and the DBPower Digital Sound Activated baby monitor does just that. This model supports up to four cameras, allowing you to monitor four rooms at once. With features like remote pan/tilt/zoom, room temperature monitoring and alert, two-way communication and manual or automatic video recording, we found the DBPower to be the best dual baby monitor.
