This hidden camera is built inside a regular USB flash drive, making it a good choice to have if you need to monitor your computer or office. See whats happening on your computer when you go out to lunch. Set this computer down on your desk, press the power button, and youre good to go. The camera inside is motion-activated, meaning it only records video when someone moves around the room. Theres also a microphone inside to hear any sound taking place during the recording.
