Best Borescope Camera for Visual Inspection Work

A borescope camera is useful for inspecting an inaccessible space, such as a drain, under the floorboards or inside an engine. Here's how to choose a good one.

The best borescope camera will allow you to see hard to reach places when doing car mechanics or home DIY.

Also known as Inspection, Endoscope or Pipe cameras, borescopes consist of a narrow rigid or flexible tube arm with a tiny camera head on one end and a built-in display on the other.

The best models also feature an LED light for illuminating dark drains or under the floorboards, tiny mirrors to allow you to see sideways, and even Wi-Fi, Bluetooth or USB connectivity to transfer the image back to the display.

You can even find inspection cameras that use a smartphone’s screen as the display device, allowing you to take as many photos or videos as your storage permits.

Typically, even the best borescope camera has a focal distance of only 1-3 inches, which means you need to get close to the object to be able to see it clearly.

This means a longer arm can be useful, helping you to go deeper with your remote visual inspection.

Let’s take a look at the top models of the year.

How do I Choose a Borescope Camera?

Before investing in a borescope camera, you should check to make sure its specifications are appropriate for your needs.

Consider the following factors before you decide which endoscope camera to go for:

  • Rigidity and flexibility

The three principal types of borescopes you can buy are rigid, semi-rigid, and flexible.

Rigid borescopes often deliver higher quality images, but if you need one for tight spaces with potential bends, a semi-rigid or flexible borescope will be essential.

A good quality semi-rigid borescope will include a remote control feature, allowing the operator to manipulate the direction of the scope tip to bend in up to four directions.

  • Direction and field of view

Determining the field of view varies depending on the type of borescope you’re using, with the angle of view from a rigid endoscope coming from the centre of the longitudinal axis, and the angle of view from a flexible video borescope coming from the tip.

The desirable direction of view will vary depending on the object you’re using the borescope for, for example, a 90° Mirror Tube is ideal for a gun or rifle barrel, while a 0° direction-of-view is preferable if the subject is ahead of an entry hole.

A backward-looking 120° borescope can be used to examine engines and other difficult-to-reach areas.

Field of view also varies, ranging from very wide down to narrow, with the wider field of view lowering the magnification and vice versa.

For example, a 90° extreme wide-angle will allow operators to see the whole picture, whereas a 30° telephoto will help you pick up details at close range.

  • Length and diameter

Depending on how you intend to use the borescope, the length and diameter should be less than the hole you plan on inserting it into.

If you need a borescope for a variety of holes and cavities, be sure to purchase one which is smaller in diameter than the smallest entry, and long enough to reach in as far as you need it to.

  • Magnification

The typical borescope features unlimited reach, removing the need for the operator to refocus.

In instances where the magnification needs to be calculated, apply the principle that the closer an object is to the lens, the greater its magnification.

This principle applies regardless of whether you’re using rigid borescopes or flexible ones.

  • Illumination

Light sources used in endoscopes have evolved over the years, beginning with incandescent lamps that were positioned at the end, to traditional bulbs.

More recently, higher quality borescopes utilize fibre-optic illumination, delivering light through glass fibres through a flexible light guide.

Such improvements in technology allow users to operate endoscopes without the risk of causing a fire or other unwanted damage.

Frequently Asked Questions

How many types of borescope are there?

There are three main types of borescope available to choose from: rigid borescopes, semi-rigid borescopes, and flexible tube borescopes.

Semi-rigid borescopes are ideal for smaller spaces, since they are bendable, whereas flexible borescopes bring a greater degree of mobility, allowing operators to cover a wider range of angles in smaller spaces.

How do you guide a borescope?

Each borescope available comes with its own set of specific instructions, so be sure you read the user manual thoroughly before use.

In general, they are operated by inserting the tip of the borescope into the space you wish to inspect, feeding the cable in as far as is required to spot any issues.

The interior of the hole or cavity will be illuminated by the borescope’s lights, with the live image is displayed on its monitor.

Final Words

The best borescope/endoscope inspection cameras offer a versatile range of options to help you to inspect problems in hard-to-reach spots, from car engines to sewage pipes.

Whether you’re looking for a borescope for casual use around the home using your smartphone as a screen or a more robust model with its own LCD screen and dual-lens functionality, there’s a borescope suitable for your requirements.
