General Wire G3-2020 Gen-Eye 3 Black & White Standard Camera Only General Wire G3-2020 Features: The Gen-Eye camera is built to take a pounding and still transmit pictures so clear you can read the head of a penny. A durable stainless steel body protects the camera from abrasive surfaces like rusty cast iron, while a scratch resistant sapphire lens keeps pictures crystal clear as the camera focuses on objects just inches away. Dimmer controlled LED lights give plenty of illumination to show what trouble lies ahead. A specially designed spring and camera shape negotiates bends and slides smoothly through the lines. There are no sharp edges to snag on the way back. All four models transmit to our digital pipe locator that pinpoints pipe problems down to the inch. We've combined a super light sensitive camera with 28 red LED's packed into a 1.6"" x 1.5"" package to give you picture perfect images in lines as large as 12"" in diameter. The camera is small enough to slide through 4"" cast iron P-traps and 3"" ninety degree bends. A special lens delivers maximum depth of field so the pipe walls are always in focus."
