If you live alone and tend to leave the house often, then HDWifiCamPro is the right app for you. With HDWifiCamPro, you can remotely access your surveillance cameras from your phone, allowing you to keep an eye out for burglars. 

If you work in the office while your family stays at home, you can still use HDWifiCamPro to ensure their safety.  What’s more, HDWifiCamPro features a video playback option for viewing camera footage from the last several hours.  

Bear in mind that HDWifiCamPro only works when you are connected to the internet. Before using this app, make sure that you are in an area with a reliable internet connection.
