In all cities, drainage pipelines are the most important infrastructures, but there can be many types of hidden dangers that can be caused by serious problems because the aging of pipelines can make a great impact on not only the life quality, but also the safety of people.

Hence, carrying out a proper periodic inspection of the drainage pipes is very important for the structure and also functional safety of the pipes. People these days use various scientific methods for maintenance/repair work.

By using such pipe inspection equipment the plumbing crew can quickly identify the fault present in your sewer or drain pipe. They can use such equipment for finding out about corrosion, pipe cracks, blockages, and root infiltration.

Once your issue is properly identified by using any pipe inspection camera, the issue can be resolved with the right techniques.

While buying such pipe inspection cameras, you may come across many different types of cameras. Knowing about different varieties of pipe inspection cameras will be important for your proper selection of the right camera type for the pipeline inspection.

The following are a few different inspection cameras that are available in the market.

1. Hand-held inspection camera


Among the most commonly available inspection cameras, these hand-held models can be considered. As its name suggests, such camera design is usually held on the hand while the cable of the camera is inserted into those areas that to be investigated.

Usually, hand-held models will be cordless type and hence more portable. You can use the inspection camera to move almost anywhere.

Also, its lightweight design will make it more versatile and you can easily carry and hold it for a long time. It is considered an ideal model while inspecting vehicles and machinery as it can be maneuvered easily.

2. Reel inspection camera

This type of camera has got a long cable and without any screen. It can be connected to a compatible monitor, like a laptop, video recorder, or any hand-held inspection camera.

Though not having a monitor is a disadvantage, but with a longer cable length, such a camera can reach greater distances.

Therefore, this kind of camera will be ideal for checking long pipes, drains, or household guttering, because the camera is able to reach further into your pipe as compared to a hand-held camera.

3. Waterproof inspection camera


Another inspection camera, which is waterproof type has been designed along with a cable and camera head that can withstand even if it is submerged into water and any other liquid.

Both the above hand-held as well as reel inspection cameras also have waterproof models. Such cameras can be ideal for inspecting any kind of water pipe, like toilet, sink, drain, or sewer.

These are commonly used for checking for cracks, blockages as they can always help to decide the extent of your problem without causing any excessive damage. You can save your time and money while working with your water pipes, thus making this device a very useful tool to possess.

4. The easy-sight sonar inspection system

This kind of system will use an acoustic method for detecting the internal status of the pipeline having water without draining all the liquid present inside the pipeline. You can get a cross-sectional picture of your pipeline and understand the general condition of your pipeline and inner wall. It is a very powerful supplement to your CCTV detection method.

Such sonar imaging devices can combine with the imaging software of pipeline sonar inspection to gather and display a real-time high-resolution contour picture. By analyzing the entire contour characteristics, condensation, the deposits, or any structural diseases of your pipe wall can also be determined.

Need For Inspection Camera:


In the modern-day, inspection cameras play an important role in viewing even the hard to reach places. These Inspection Cameras are helpful to view objects where it is difficult to view through the own eyes. The Inspection Camera is one of the best options for reaching to access places and an alternative to the normal camera. These cameras are perfectly designed for viewing the accurate quality picture where it is hard to reach places that include cavity walls, under the floorboards, and many others.

How To Choose The Best Inspection Camera?

Remote visual inspection becomes one of the popular options for various applications. Most people find it difficult for choosing the right inspection camera suitable for their job. There is also no special training or skills required to work with these cameras. Normally, this inspection camera is equipped with the 3 elements such as

  • The Camera
  • The Handset
  • The Flexible Pipe

The Camera:


Choosing the Camera at the size of less than 10mm is most important. Normally, the borescopes and endoscopes have been developed for engineering applications and medical purposes. The name “borescope” came into existence as these cameras are used for inspecting the gun bores. These cameras are operated with fiber optics along with a better light source for enabling the flexible pipes. Normally, the observers could easily view the end image accurately through the TV monitor connected to the camera.

With the introduction of the smaller image sensors equipped along with the cameras, it is more useful for various engineering applications. Image sensors made with the inspection cameras are also affordable these days. With the tiny camera heads assembled, it is easier to focus manually into the dark and difficult to access places.

How To Use An Inspection Camera?

  • Determine the length and diameter of the insertion probe
  • Choose between the rigid
  • Choose appropriate flexible insertion rod
  • Use the inspection camera with a special monitor hub
  • Optical borescope allows seeing a defective place or part through an eyepiece
  • Inspect through spark plug holes using an inspection camera

Image Sensors And Resolution:


The inspection Camera is equipped with Image sensors for assisting the cameras. With the introduction of full HD inspection cameras at the most affordable price range at, you can easily save more money in the process. The smaller the pixel of the camera the less light it would reach so that the sensor added is lower in the sensitive range.

Focal Length:

Before choosing the Inspection Camera, it is important to analyze the camera quality, image sensor along with the focal length. When you like to get a view of the small spaces like a cylinder of an engine, it is important to use the small camera fixed on close range. Normally, the cameras having the focal distance set at 20mm are suitable for viewing the larger objects into the bigger space it gives the accurate resolution.

Low Light Sensitivity:


LED placed at the end of the camera allows to easily get a clear view around the place. LED is energy efficient and performs well t the total darkness.
