Webcams are great for video chatting and snapping self-portraits. But you can also use them to monitor your house or work. You can use one to watch your pets while you're not home or have it monitor your front door. It's really up to you.
Of course, a webcam won't do any of that on its own. You need the right software.
My Webcam Broadcaster is a good choice. It allows you to access your webcam over the Internet. You can easily do that from another computer or you can view it through a smartphone. Just install the handy app on your iPhone or Android.
The program can also take photos on a set schedule in intervals ranging from 10 minutes to 24 hours. My Webcam is compatible with webcams built-in to computers and most USB webcams. It will also control Logitech and Creative Webcams featuring pan and tilt.
