Access rods are used to push and move the camera through curves and corners.
They are moving rowers with a camera mounted on them. They can be operated remotely and used to conduct a CCTV survey for sewer lines.
A sonar system produces ultrasonic waves that help in mapping the sewer network and locating the blockage.
A small camera that is connected to a computer is driven through the drainpipes. It sends footage and image to the system that displays all the results on an LCD screen. This helps to find the source and determine the magnitude of the problem.
Robotic or rover cameras are connected to the system via Bluetooth or Wi-Fi technology. They are operated remotely by CCTV drain surveyors and can move easily in the bigger sewer lines. They offer high efficiency due to their extended range and wireless controls. They can prove helpful in conducting industrial CCTV drain survey
