Market requirements and materials used for pipes vary globally. Mini-Cam’s

Mul -Frequency Sonde is designed to provide the user with the ability to choose, via the

SOLOPro CCU, the frequency required to aid loca ng the camera in diﬀering pipe materials.

The Mul -Frequency Sonde draws power from the 12V line which also powers the camera

module.

A single control signal line is used to control the func on of the Mul -Frequency Sonde

which determines the frequency and also whether the Sonde is ac ve or inac ve.

The Mul -Frequency Sonde provides a connec on to the camera, ensuring connec ons are

made between the Rod & Camera to allow the system to work correctly.
