Verdict
The Teslong triple lens borescope solves the borescope’s fundamental problem in an unusual way. The listing states three cameras in the probe tip with one button toggling between the front facing camera and both side views for a combined 234 degree field of view, a 5 foot probe, a 5 inch IPS colour screen, a supplied 32 GB micro SD card recording JPEG and MPEG-4, and no WiFi, driver or app requirement. For inspecting cylinder bores, pipes, wall cavities and ductwork, seeing sideways without steering is a genuine advantage.

The listing does not publish probe diameter, image resolution, lighting or waterproof rating. Probe diameter in particular decides whether it fits your application, so check it before buying.
The Problem Side Cameras Solve
A single forward facing borescope looks where the probe points, which is along the hole. That is the wrong direction for most inspections. Inside a cylinder you want to look at the bore wall, not the piston crown. Inside a pipe you want the wall, not the far end. Inside a wall cavity you want the back of the plasterboard, not the next stud.
Traditionally you solve this with a mirror attachment, which is fiddly and reverses the image, or with an articulating probe, which steers the tip with control wires. Three fixed cameras solve it differently: the sideways view is always available, instantly, with nothing to steer and nothing mechanical inside the probe to wear out or jam.
Fixed Cameras Against Articulation
Each approach wins somewhere. Fixed side cameras are faster, more robust and cheaper, and they give you a view in both directions at once. An articulating probe aims precisely, can follow a curved surface, and can point at something the fixed geometry misses. If your inspections are mostly “look at the wall of this cylindrical thing”, fixed cameras are better. If they are “find the specific crack and get square to it”, articulation wins.
Durability favours the fixed design. Articulation cables stretch, and a probe that has lost its steering is a probe with a bulge in it.
No App Is a Feature
Borescopes that use a phone are cheaper and endlessly frustrating: an app that has updated itself, a phone that will not grant camera permission, a connector that has changed, a battery that is flat because you were also using the phone as a torch. A dedicated 5 inch screen removes all of that, and it gives a larger, brighter image than most phone apps manage inside a dark cavity.
Recording to a supplied 32 GB card in standard formats is the same idea. The files are readable anywhere with no software, which matters when the images become evidence for a customer.
Getting a Usable Image
- Insert slowly. Most borescope damage happens by pushing a probe into something it cannot pass.
- Clean the lens. A smear of oil on the tip looks exactly like a fault inside the bore.
- Vary the lighting distance. Too close and everything is glare; too far and detail disappears.
- Record video rather than stills while moving, then pull the frame you need afterwards.
- Note the orientation. Without a reference it is easy to lose track of which side of a bore you are looking at.
Strengths
- Sideways views without mirrors or articulation.
- Standalone screen, no app or WiFi to fail.
- 32 GB card supplied with standard file formats.
- Nothing mechanical in the probe to wear out.
Limitations
- Probe diameter, resolution and waterproof rating not published in the bullets.
- Fixed cameras cannot be aimed at an awkward target.
- Three lenses means a larger tip than a single camera probe.
- Five foot probe limits reach in long runs.
How It Compares
Articulating borescopes steer the tip and suit precise inspection of a specific feature, at a higher price and with wear items inside the probe. Dual lens models offer a front and one side view with a slimmer tip. Our ranking is in the borescope roundup, and thermal camera versus borescope covers when to reach for each.

Frequently Asked Questions
How does the triple lens work?
The listing states three cameras built into the end of the probe, with one button toggling between the front facing camera and both side view cameras, for a combined 234 degree field of view.
Does it need an app?
No. The listing states that WiFi connections and downloading drivers or apps are not required, because the 5 inch IPS screen is part of the instrument.
Does it record?
Yes. The listing states a 32 GB micro SD card supplied, recording JPEG images and MPEG-4 video, with easy transfer to a computer.
Is it better than an articulating borescope?
It depends what you are inspecting. Three fixed cameras see sideways instantly with nothing to break; an articulating probe can aim precisely at one target and follow a surface, which fixed cameras cannot.
