Not all nanny cams have Wi-Fi, but it is an increasingly more popular feature. Some nanny cams have built-in Wi-Fi, while others require an additional device such as a Wi-Fi adapter or a separate monitor with Wi-Fi capabilities. Nanny cams without Wi-Fi may still be a good option for those who prefer not to have their footage stored on a cloud service or who have limited internet access. However, with Wi-Fi-enabled nanny cams, users can typically view their footage remotely, receive notifications, and control the camera through an app on their smartphone or tablet.
