The IP Camera app for the iPhone will help you take advantage of the iPhone’s camera, putting it to good use if you want to take discreet time-elapsed photos. Capable of snapping photos every 12 to 15 seconds, this app will also transfer those snapped images to a local Web page that can be accessed later from other computers that are on the same network. All you need to do is make sure your handset has Wi-Fi connectivity turned on, where the IP Camera app will run indefinitely until you shut it down or receive a phone call. Sounds like $1.99 worth investing if you want to catch your colleagues performing some hanky panky while looking oblivious.
