There are a number of key differences between these low-end products and the VJ-ADV
1.
Articulation. Low-end videoscopes do not articulate (meaning the camera section cannot be controlled and pointed in different directions). A scope without articulation is like a car without a steering wheel. It’s great as long as you only need to go straight. These low cost scopes may work well for certain types of inspections, such as small-bore pipe inspection, where there would be no room to move an articulating tip. But in the vast majority of cases, the usefulness comes from being able to place the insertion tube into an inspection area and then move the camera around to see what you need to see. The ability to articulate the camera is the most critical feature missing from low-end scopes, and the value of articulation
cannot be overstated.
2.
Image or video capture. If a technician ever wants to archive pictures of an inspection, get a second opinion, compare the same part from one date to the next, or show a customer the results of an inspection, you must have image and video capture. Most low-end scopes do not have image or video capture. Some of these products may have a video output through which you could record an inspection on a computer, but this adds complexity and cost and reduces portability.
3.
Image quality. The VJ-ADV uses a high end camera and lens system to deliver 307,200 pixel resolution and a focal range of 4mm to infinity. Check the resolution and focal range of these systems and you will see that they usually are inferior.
4.
Insertion tube material. VJ-ADV’s insertion tube is very rugged and yet pliable enough to snake through bends and elbows and curves. Some of the low-end product insertion tubes are too rigid to do this. Some are made out of metal gooseneck material, much like electric wire conduit. This type of insertion tube material, combined with a lack of articulation, significantly reduces the types of inspection scenarios in which it can be used.
