Manhole Inspection

The SPiDER is a truly wireless, color manhole inspection technology in a lightweight and compact form factor. It is a scanner that can calculate its position in the manhole shaft by using its sensor data to measure its incremental motion. This technology frees inspections from problems associated with inaccurate, poorly calibrated cable counters and poorly managed cables. It also provides live video stream and recorded video, making it a suitable tool for infiltration and inflow studies that depend on live video to detect moving water.
