Security cams are an obvious use for a wireless camera that can be connected to a computer. Even those systems that require their own power connection are still quite flexible, as there are many places which have convenient power connections but which lack a convenient network connection.

The better security cams are also capable of infrared imaging, with night vision capabilities to allow twenty-four hour coverage. WiFi capable cameras can even be moved around to make it more difficult for a prospective burglar to know the locations without requiring purchase of enough cameras to break the bank.

WiFi cameras are also useful because several can be placed as needed and the viewer can switch from one to another as needed. While there are seldom enough network connections to allow a camera to be place wherever might be convenient, it is quite possible to have that many power connections.

The availability of programs that allow the camera and computer to determine if there is motion in the field of vision and activate an alarm greatly increased the ability of a user to create their own security system in case of need.

Almost all security cams will record their observation. Many can also determine how much space is present on the associated hard drive, and begin to write over the oldest files when they’ve used their allowed space. This provides a compromise between keeping files forever and having reasonable limits on how much storage to purchase. Some can even record only periods when something is moving on screen, with only period frames at other times to show the passage of time.

Not all security cams are intended to watch for burglars. Another use is to watch babies. The ability to feed the video through a network into a web browser can allow a parent or other person to watch the baby from elsewhere in the house or even across the world. The systems can also be used to keep an eye on pets, especially animals that are kept outside of the house. Farmers can use WiFi cameras and signal repeaters to keep watch or periodically check on current conditions in a barn or even a field.

Conference cams are a growing requirement in modern business. With conference calls around the world to multiple sites taking place increasingly, there is need for a camera that can provide clear pictures, transmit them to the network and easily move around the conference room.

Another business related camera task is the creation of multimedia presentations. From creation of commercials to video training files, businesses can find many applications for the ability to produce video.

Home cams are almost a necessity. Webcams are growing to be as common as internet connections, with many teenagers almost refusing to believe that anyone would talk on the telephone without being able to see each other.

Another use for home digital and webcams is creation of video clips. This can range from creation of traditional home movies to the creation of even professional quality video. With the appropriate software a good camera can allow the user to mix audio and moving video to create music videos, reports, commercials or any number of other options.
