Keykatcher is a unique solution for parents, employers and anyone that needs to know what is happening to the computer when they are not around. When plugged between your keyboard and computer the Keykatcher logs keyboard activity - no software to install, no system resources used, no software needed.
It took about 15 seconds to install the Keykatcher since all that has to be done is plug it into the back of the computer; making it not only the easiest way to monitor a PC but the quickest to install. The 2-inch device looks more like a keyboard adaptor then a sophisticated monitoring device. It's diameter is the same as a regular keyboard plug so it won't interfere with a PS/2 mouse, although it does sick out almost 2 inches from the back of the computer.
