The IRIS pan-and-tilt mainline crawler from Insight Vision Cameras incorporates a motorized crawler and a power-rewind/feed-assist cable drum. The level rewind reel allows the video cable to be rewound at the same speed as the crawler is moving to avoid running over the cable. It allows full 360-degree rotation and 180-degree pan for lateral sewer pipe inspection. It is designed for inspection of pipe from 6 to 12 inches in diameter (and up to 18 inches with an optional pneumatic wheel set). The motorized drum holds 600 feet of flexible and rugged video cable that will withstand the harsh environment found in sewer pipes. The unit is built with a telescopic handle and self-contained wheels for easy movement and portability. It operates on Windows 7 64-bit software with 500GB of solid-state drive. It incorporates an integrated accessory power outlet, multiple recording ports, HDMI external port, 10-inch LCD touch screen, Windows apps, snapshots, on-screen footage, text writer and internet remote desktop support. 800/488-8177; www.insightvisioncameras.com.
