TV inspection robot: wireless or wired?

TV inspection plays a crucial role in many industries, for example in monitoring underground infrastructures, inspecting industrial ducts or assessing installations in confined spaces. With the evolution of technology, the choice between a wireless or wired television inspection robot (TVI) has become a central issue. In this article, we'll look at the specifics of these two technologies and the criteria for making the best choice.

What is a TV inspection robot?

A television inspection robot (VIT) is a device designed to visually assess hard‑to‑reach spaces. It is commonly used in pipelines, industrial ducts, underwater installations or confined environments such as tanks or reservoirs.

Equipped with high‑definition cameras, sometimes up to 4K, and powerful LED projectors, this robot captures precise images, even in low‑light conditions. Its role goes far beyond simple visual inspection: it is often used to detect cracks, damage or obstructions that could compromise the safety or efficiency of infrastructures.

Wireless ITV robots: benefits and applications

Wireless ITV robots, such as Multinnov's Roview2, represent a significant advance in the field of industrial inspection. These devices are equipped with technologies that enable them to operate autonomously, without relying on a cable to transmit data or power.

Benefits of wireless ITV robots

- Greater mobility: without the constraint of a cable, these robots can move freely in complex environments. This is particularly useful in pipes and ducts, where tight angles and obstacles make it difficult to use a cable.

- Extended range: the range of a wireless robot depends mainly on the quality of its signal. In confined spaces, materials such as metal can facilitate signal transmission, enabling the robot to cover considerable distances.

- Ease of deployment: with no wires to connect or manage, these robots can be rapidly deployed, reducing lead times and simplifying their use, particularly in emergency situations.

Typical applications

Wireless robots are particularly well suited to confined environments, where autonomy and flexibility are essential. They are used in :

- Underground industrial ducts.

- Vats and tanks where access is limited.

- Inspection of metal structures, where signal transmission is optimized.

With its robust performance, the Roview2 perfectly illustrates these advantages, combining mobility, precision and technological innovation.

Wired ITV robots: applications and limits

In contrast, wired ITV robots remain a popular option, particularly in environments where signal stability is essential.

Typical applications for wired robots

- Complex signal environments: in environments where materials absorb or block signals, such as thick concrete structures, a wired robot guarantees stable data transmission.

- Long‑distance inspection: some wired ITV robots can cover greater distances than wireless models, thanks to a dedicated power and transmission cable.

- Extended use: unlike cordless models, corded robots are not limited by battery life, making them ideal for long or complex inspections.

Limitations of corded ITV robots

However, these devices do have their drawbacks:

- Limited mobility: The cable can be cumbersome in narrow or obstructed spaces.

- Risk of cable damage: In abrasive environments, the cable can become worn or damaged.

- More complex installation: Deploying a wired robot requires more time and organization.

Choosing between cordless and corded ITV robots

The choice between a cordless and a corded ITV robot depends on a number of factors. Here are the main criteria to consider:

Inspection environment

- Metal or open environments: Wireless robots, like the Roview2, are perfectly suited to these environments, thanks to their excellent signal transmission.

- Concrete or complex environments: Wired models are preferable in structures that block or absorb the signal.

Distance to be covered

- For inspections over short distances (less than 200 meters), wireless robots are effective.

- For inspections beyond this range, wired robots offer greater stability and autonomy.

Task complexity

- For rapid inspections or in changing environments, wireless robots offer greater flexibility.

- For longer inspections or those requiring a continuous power supply, a wired robot is more appropriate.

Logistical constraints

- If time or resources are limited, a wireless robot is easier to deploy.

- For abrasive or risky environments, wired robots require robust cables and extra precautions.
