The DCS-825L is a brilliant Wi-fi baby cam and after a few weeks of testing it out for D-Link, I can tell you I miss it since I reluctantly handed it back over. This baby monitor works by placing a webcam in the nursery and using your smart phone, tablet or computer to view the live stream via Wi-fi. By using your phone/tablet, you eliminate the need for an additional device and since we carry our phones everywhere anyway, handy too. You just need to download the free D-Link app, link your webcam and Wi-fi, and you are ready to go. You can create an account for additional features and configure the settings to your own preferences. The attractive webcam comes in white with blue and pink rings, and sits firmly on a sticky stand or can be wall mounted. The webcam plugs in with an extra long cord or connect to an external USB battery for total portability.
