Digital Still Cameras

These cameras can be purchased in any high street shop and can take excellent pictures in most situations.

The pixel resolution of the current models have easily reached 7 million pixels (7-mega pixels). Some point and shoot models like those produced by Canon or Nikon boast resolutions in excess of 10 million pixels.

At these resolutions, and with high shutter speeds like 1/125th of a second, it is possible to take jpg pictures on a continuous or motion detection basis that will capture not only anyone running past the camera scene, but even the faces of those driving past.

These cameras can be plugged into the USB port of any computer (most of them now have USB capability)and pictures can be taken of any camera scene. All that is necessary is for the camera to be mounted on a wall bracket and pointed in the desired direction.

Modern digital still cameras can take 500 kb snapshots in the space of 1 second, and these snapshots are then automatically downloaded by the camera software straight to the computer for storage as timed and dated JPEG files. The images themselves don't need to stay on the computer for long. If the computer is connected to the Internet, then the images can automatically be uploaded to any other computer anywhere in the world, as and when the pictures are taken.

The user does not need to lift a finger except to simply plug the camera in and point it in the desired direction. The direction could just as easily be the street outside a house, or the entrance to a bank or underground station.

Digital still cameras are now being made with in-built wireless connectivity, so that no USB cable is required; images are simply transmitted wireless through walls or ceilings to the computer.
