Digital inspection cameras are useful for seeing into walls, down conduits, and anywhere else only a mouse can fit. As part of Bosch's 12-volt platform, the new PS90 has a 2-11/16-inch screen with a maximum resolution of 324x240. The camera is 7-1/4 inches long and comes with a 48-inch flexible snake that accepts extensions totaling up to 30 feet. The lens head, equipped with an LED, is 11/16 inch in diameter – small enough to fit through the hole in an electrical box. Keep in mind that even though it's called a camera, this device does not have the ability to capture an image. It's sold with a hook, a magnet, and mirror attachments.
