The hardware-based Mouse Jiggler prevents your computer from going to sleep while you work or play. This plug-and-use USB device comes in two versions and creates constant mouse activity so your computer won't go idle and trigger screen savers or sleep mode—eliminating the need to log in repeatedly.
Mouse Jiggler's small size makes it easy to carry and keeps it out of the way while you work. At 2.32" x 0.71" x 0.39" (59mm x 18mm x 10mm), MJ-1 is the size of a small thumb drive. Mouse Jiggler appears as a USB mouse to the host computer it’s plugged into—and its presence and use will be logged by some operating systems. Mouse Jiggler should be used only in compliance with applicable workplace IT policies.
Presenters use Mouse Jiggler because it allows them to present without the screensaver popping up in the middle of the presentation. Employees who are unable to change their system sleep settings or install unapproved software on their computers find Mouse Jiggler convenient to keep screen savers or login screens from activating.
IT professionals use the Mouse Jiggler to prevent password dialog boxes due to screensavers or sleep mode after an employee is terminated and they need to maintain access to their computer.
Computer forensic investigators use Mouse Jigglers to prevent password dialog boxes from appearing due to screensavers or sleep mode. With many computer hard drives now employing full-disk encryption, such modes can greatly increase the time and cost of a forensic investigation. When combined with a WiebeTech HotPlug™, investigators can transport a running computer without shutting it down or worrying about logging in.
Whether you're a forensic investigator, technician, or IT professional, the CRU WiebeTech Mouse Jiggler is a useful tool.
