The Critical Parts and Benefits of In-Line Sewer Cameras

In-line sewer cameras offer multiple benefits for a trained plumbing specialist. These include determining the nature of a line blockage (roots, line separations, artificial material blockages, and material flow problems), integrity inspection of the sewer line, and extent of the damage to be repaired or replaced. Cameras also help plumbers prepare with the right equipment when salvaging an existing like with industrial equipment such as high-pressure jet cleaning tools. The wrong tool could damage the pipe, but a camera will confirm the condition and proper pressure approach every time.

On the other hand, not using a camera can be extremely costly for a homeowner. For example, a misjudgment of the line problem could end up in charges for a far more extensive line plumbing repair that turns out not to be necessary, including excavation. In addition, there could be problems with estimating the exact location of the issue as well, which could make the problem worse and bigger repair. Again, accuracy in knowledge is a win-win for everyone involved.

The main features of an in-line sewer camera are primarily based on the camera apparatus itself, the data feed cable which comes in the form of an insulated and sealed fiber optic cable for heavy-duty applications, the LED lighting mechanism on the end of the camera to illuminate the details filmed, and the video monitor above ground which allows the plumber to see the progress in real-time as well as record the findings for review and analysis.

In-Line Sewer Cameras Head and Assembly

If there is a critical part of the entire in-line sewer camera system, it’s the camera head. This is the most expensive component in the setup and the part that captures the critical information. It is also extremely sensitive and easy to damage. An untrained technician or someone new to the job can do a lot of damage very quickly forcing the camera apparatus through a line and, in essence, making the camera head a luxury battering ram to a blockage. Not only does that ruin the whole purpose of the effort, but it can also damage any information capture as well. While these industrial cameras are specifically designed and built for their environments, repeat use of jamming the camera through resistance simply destroys it over time.


Attached to the In-line sewer cameras rear is the fiber optic cabling, shielded in an industrial sheath wrapping so that the materials and moisture in a sewer line don’t damage the fiber itself. It’s also designed for easy cleaning so that the equipment is sanitized after the fact before packaging again for transport. This type of cabling doesn’t do well with extreme bending or folding. Instead, it is wound on a large wheel assembly for protected storage when not in use. The fiber optics allow for significant data transfer from the camera to the monitor, allowing for high detail with a closed-circuit system. The cabling and camera are sent through the line with a push rod that gives the technician control and the ability to propel the camera through the line at distance.

LED Lighting

Attached to the top of the camera apparatus is a sealed LED lighting unit that provides a tight concentration of illumination. While it’s not going to light up a neighborhood, the LED unit provides more than enough light for the camera to pick up detail and show in clarity and even color what’s going on in front of it. With good practice, the lighting and image give the technician enough information to see what’s happening as he sends the unit through, how to navigate issues, and when the line cannot be traveled any further.

The Monitor

Finally, the monitor is the display that the technician watches and records with, as the camera inside the line does the job. Directly connected to the fiber optic cabling, the monitor will display in detail and real-time what is happening in front of the unit in the line as well the time stamp. Some advanced units can also display various sensor data such a temperature and humidity as well, which is why this kind of equipment is also used by archaeologists and law enforcement/public safety for similar confined space visual examination.

As discussed above, modern plumbing technology is now light-years from where it was only two decades ago. And in-line pipe inspections allow far better repair performance as well as saving consumers thousands of dollars from unnecessary repairs. In comparison to how things used to be done, it would be foolhardy to attempt any sewer line repair today without a camera inspection first.
