How Does a Pipe Inspection Camera Work?

Pipe inspection cameras consist of small color cameras at the end of a semi rigid push rod, which are connected to a monitor to view the inspection area. They give clear pictures of the internal condition of pipes and aid in identifying countermeasures and action to be taken to resolve future actions.

Pipe inspection cameras are a vital tool for pipe inspectors, plumbers, and others involved in the maintenance of plumbing and sewage systems. These useful camera systems are made up of a video camera, which is connected to a flexible push rod. This camera transmits images of the pipes as it moves through them, which can then be seen on a color monitor. In this way, users can get a clear view of the condition of the pipe system and any problems that might need to be addressed. But how exactly do pipe inspection cameras work? It’s important for anyone who uses them to understand their inner workings, as well as be able to explain how they work to clients.

Pipe inspection cameras deliver excellent benefits to users and their clients. Using them saves a lot of time and money, offering a less disruptive experience compared to traditional inspection methods or costly disassembly or excavation work.

The Basics of How Pipe Inspection Cameras Work

In the past, inspecting pipework for leaks and other problems required a lot more effort and guesswork. The land around the pipework would often need to be dug up to identify existing problems, which was expensive and time-consuming. Today, most pipe inspectors and plumbers simply use cameras instead. They are a lot less intrusive and enable taking a close look at the inside of pipe systems without having to dig around them.

The sewer camera is attached to the end of a semi flexible line, which can be inserted into the entrance to a pipe. The ability of these lines to slither through pipes means that they are often called snake cameras. This camera then transmits real-time images to a color monitor so that the person inspecting can see what’s inside. The cameras themselves aren’t (or shouldn’t be) used to clear blockages or other issues but instead should give a clear view of what’s happening in the pipe. The camera can be used to identify blockages, leaks, corrosion, or other problems that might exist with the pipe system.

Modern Inspection cameras a continuous communication ribbon to transmit images from the camera head to viewing monitors.  The camera heads themselves vary as well when it comes to the diameter of the camera head.  The benefit of a larger camera head is that they typically provide more light output and can illuminate the area better.   However, the larger diameter camera heads cannot fit into a smaller diameter pipe.   The standard diameter of a plumbing camera is around 1 inch in diameter.   But even with the standard push camera systems there are variations with the camera head.  A straight view camera head is standard but you can also have the advanced features of a self-leveling camera head.  What is a self-leveling sewer camera?  This inspection camera automatically and continually levels itself when viewing the inspection area, ensuring upright pictures at all times.  No more guess work as to which way is up. This makes pipe inspections easier and more efficient, eliminating the need for upside-down videos and images.  This makes documenting and explaining the inspection much easier.    Another option to consider is a sewer camera with locator.   Not only does this snake camera provide a head with a transmitting device but you will also be required to utilize and above ground locator.  This locator work similar to a metal detector in that you will sweep the device back and forth above ground to locate the sewer camera with transmitter.  The difference is that the two devices are working together.  Not only is the sewer camera head transmitting a digital signal but the locator above ground is searching for that same signal.  This helps you to pinpoint the exact location of the problem.   A point to make is that some sewer camera locators will identify the location but others will also indicate the depth of the camera head.

Obviously, there isn’t any natural light getting into the pipes. For this reason, a pipe inspection camera needs to have a powerful light to illuminate the pipe and allow the camera to record. The camera is also water resistant, which enables it to make its way through a pipe without being damaged by coming into contact with moisture.

The cable on an inspection camera is also connected to motors that allow the camera to be controlled. The camera can be moved around to allow it to get images from different angles.

Problems Pipe Inspection Cameras Can Detect

Pipe inspection cameras can be used to detect a number of different problems in sewer and plumbing systems. By presenting a clear image of the inside of a pipe, they can show any issues that might have arisen or could be developing. Here are some of the problems that can be detected with a pipe inspection camera.

• Root penetration from trees and plants — when the roots from trees and other plants enter pipes, it can cause damage and create blockages.
• Cracked, broken, and damaged pipes — when there is damage to a pipe, an inspection camera can be used to spot the problem and help inspectors determine what steps might need to be taken to repair it.
• Blockages — blockages are common issues that occur in pipes and can be difficult to clear, but inspection cameras can help with identifying the problem.
• Sagging sewer lines — sagging lines can cause blockages or slow flows of waste; fortunately, pipe inspection cameras can find the problem area.

How to Use Your Pipe Inspection Camera

If you have bought a pipe inspection camera, it is essential to learn how to use it. When you have invested in a valuable piece of equipment, you want to get the most from it. Additionally, you don’t want to damage the system you have bought, which could be a risk if you use it inappropriately. There are some key steps you can follow to use your camera effectively, get the best results, and avoid causing damage to the camera system.

Firstly, it’s important to follow the manual that is provided with the camera you buy. It will contain all of the pertinent information for using that particular model and can also point you toward resources for additional support. Each camera may operate slightly differently, so reading the instructions for use and maintenance is a must.

Secondly, you need to know what your camera can and can’t do. While it can snake its way through a pipe, it’s not designed for clearing blockages. Therefore, any clogs should be cleared to enable the camera to get through. And, although pipe inspection monitors are usually water resistant, they are not waterproof. This means that they are suitable for environments where moisture might be present, but they shouldn’t be submerged or saturated with water. Cameras and their cables are waterproof, which enables them to move through pipes with ease.

The Importance of Pipe Inspection Camera Cleaning and Maintenance

Owners of pipe inspection cameras should clean and maintain their camera systems to keep them functioning properly. Pipe inspection cameras need to be cleaned regularly due to the environments they are used in. Ideally, the camera should be wiped down after every use to remove contaminants. A soft rag can be used to wipe away anything that might have gotten onto the camera and lens. A gentle detergent could be used for cleaning too, and rubbing alcohol can be an effective lens cleaner that won’t cause any damage.

Pipe inspection cameras are extremely useful, but it’s important to use them properly to get the most from them.
