"This is the gear that those nasty reporters use when they have to record something with a hidden camera"(283).
THE BUTTON CAMERA
What Lisbeth probably used to record Bjurman attacking her was something like this high-definition hidden camera kit designed for law enforcement professionals. It records from WVGA up to 1080p and can also capture 2MP still images. Most devices like this feature overwrite recording, motion activation, and a time stamp each file.
They often include two different cameras, standard and wide angle. Button and screw covers just screw on over either lens, allowing the user to make a switch in seconds. They come equipped with a wired remote control that can start and end recordings with the touch of a button. All files are recorded to an SD card, so footage can be reviewed on any monitor or PC.
