In modern infrastructures - sewage networks, piping, industrial tanks or underground galleries - internal visual surveillance is a major challenge for reliability, safety and durability.Televisual inspection (TVI ) has become an indispensable solution: a camera, robot or inspection drone capable of penetrating confined environments to detect anomalies invisible from the outside. French company Multinnov has positioned itself as a key player in this technological revolution, thanks to equipment such as the Roview2 and Stereo2specially designed for harsh environments.
Televisual inspection: technology and operation
ITV (Inspection TéléVisuelle) is a non-invasive inspection method that involves introducing a camera or equipped robot into a pipe, tank or engineering structure to obtain images and visual data of its internal condition. As Multinnov explains, "industrial television enables access to areas inaccessible to the eye, while limiting risks and costs". The classic procedure includes :
- preparing and identifying access points and the environment (confined spaces, obstacles, depots);
- deployment of the equipment, which may be a camera cart, a wireless robot or a drone, depending on the context;
- inspection and recording, with HD or 4K video, powerful lighting, and metadata (distance, inclination, diameter);
- analysis and report, often coded according to NF EN 13508-2+A1 for drainage systems.
For industrial and infrastructure applications, Multinnov's products include: the Roview2a wireless inspection robot for difficult networks, and the Stereo2a drone designed for confined aerial spaces - silos, ducts, chimneys - with no GPS signal.
Safety and maintenance benefits
Enhanced safety: One of the first benefits of ITV is the reduction of risks for operators. In confined environments - potentially hazardous atmospheres, narrow areas, work at height - human intervention is always at risk. By using visual inspection robots or drones, technicians remain at a distance, reducing accidents and the costs associated with safety protocols.
Increased efficiency: TV inspectionspeeds up diagnosis, reducing preparation and intervention for critical infrastructures. According to Multinnov, their solutions can reduce intervention costs by up to 70%.
Optimized maintenance and economies of scale: Thanks to precise imaging and data logging, anomalies can be detected early - cracks, seepage, corrosion, obstructions - and targeted operations planned at the right time. This avoids unplanned stoppages, over-inspection and premature replacements.
Next-generation visual inspection: The integration of high-definition cameras, stabilization systems, powerful LED lighting and specific data collection means complete traceability and a fine-tuned view of infrastructure conditions.
