Key logger is a small hardware device designed to capture any key pressed during the computer usage time. Its compact, cylindrical size makes it look like a typical PS/2 extender. The installation is easy as 1-2-3. You just have to plug the key logger into your ps2 slot in your PC and connect the keyboard cable to the other end. No software installation is needed! Thanks to this, hardware key logger is undetectable by any malicious software detection programs. The captured data is stored outside computers memory, in non-volatile flash memory, therefore it is secure from any hacker activity. It can only be accessed by typing secret password, only known to the administrator. The devices menu is in English but our company is currently working on other language versions. Any word processor could be used to retrieve captured keys and save them into a text file. Please note that this procedure may be completed on computer other than the one monitored. Our newest model kl2000t is equipped with a time stamp option which enables the user to keep track of any keys typed in time. Every 15 minutes a time stamp is edited into logs. Kl2000t model have a build-in battery, which has enough power capacity to sustain the inner clock for over 2 years of a non-usage time. The battery is not used when the keylogger is in use so it will only be used if the device is unplugged. If a complete discharge situation occurs, the only data lost will be the current time, easily to be set via main menu. No previously captured information will be lost! Moreover, it is equipped with 2mb memory with 2,000,000 keystroke capacity, which is approximately 12 months worth of typing!
