A portable video pole camera system from Zistos allows visual inspection of confined areas from outside the space, keeping the worker safely away from hazards. It can be used in pipes, sewers, underground vaults, tunnels, tank cars, storage vessels, septic tanks and dry wells. Its use can significantly reduce confined-space inspection costs by requiring fewer workers, less equipment and shorter on-location time. 631/434-1370; www.zistos.com.
