When a thermal borescope visual inspection job puts you in front of a pipe, a duct, a wall cavity, or a machine, the real decision isn't just "does it have a screen?". You also have to think about how far the probe reaches, how many viewing angles you can get, and whether you're comfortable buying new or used. These four borescopes are all visual inspection tools, but they sit in very different spots: a low-listed-price USB-only model, two mid-listed-price screen models, and a used triple-lens unit with a longer cable.
Quick Take
At first glance, the KERUI 1M Waterproof Endoscope Camera is the lowest-listed-price way into this category, but it relies on an Android phone or PC for viewing. The LCD Endoscopes 1080P HD Industrial Borescope adds a 4.3-inch screen and dual lenses without leaving the middle of the listed price range. The New 4.3-inch IPS 1920P Borescope gives you an IPS display and a 16.5-foot cable in a new condition. The Used DEPSTECH DS520 is the only triple-lens model here, with a 5-inch IPS screen and the same 16.5-foot cable length.

- Go with LCD Endoscopes if you want a built-in screen, dual lenses, and a modest listed price.
- Go with the New 4.3\" IPS model if you want a new unit, a 16.5-foot cable, and an IPS screen.
- Go with Used DEPSTECH DS520 if you need a large 5-inch screen, three camera angles, and maximum viewing flexibility.
Product Notes
KERUI 1M Waterproof Endoscope Camera 6LED 3-in-1 USB Industrial Borescope
At the low end of the listed price range, this KERUI model keeps the setup simple: a 7mm waterproof camera head, 6 LEDs, and a 1-meter flexible cable. It connects through USB and an Android interface, so you will need an OTG cable and a phone or PC that can accept it. The camera resolution is 640*480, which gives you a basic look rather than crisp HD detail. It is a new, low-listed-price way to confirm what is behind a small gap. Limitation: no built-in screen, and the resolution is more basic than the HD options.
LCD Endoscopes 1080P HD Industrial Borescope 4.3-inch 8mm Inspection Snake Camera
This option brings its own 4.3-inch color LCD screen, so you can leave the phone out. A dual-lens design lets you switch between lenses with a three-second button press, and adjustable LEDs help in darker spots. The 8mm camera head is a little wider than the KERUI's 7mm but still narrow enough for many openings. With 1920P resolution, SD card support, and a close focusing range, you will want to get near the target. The screen tops out at 4.3 inches, which is smaller than the 5-inch display on the used DEPSTECH model.
New Endoscope Camera with Light, Borescope Camera with 4.3\" IPS 1920P 16.5 FT
This new model covers a lot of basics in one mid-listed-price package: a 4.3-inch IPS screen, 1920P resolution, an 8mm camera head, and a 16.5-foot cable. It also includes IP67 waterproofing, 8 adjustable LEDs, a 180° image rotation, and 2x zoom, which can help when you cannot reposition the cable. It is a reasonable middle ground between the no-screen KERUI and the used DEPSTECH. Limitation: the focus range is close-up, and the 4.3-inch display is smaller than the DEPSTECH's 5-inch screen.
Used DEPSTECH DS520 Endoscope Triple Lens Inspection Industrial Borescope 16.5ft
The highest listed price goes to this used DEPSTECH, and it brings the most capability in the group. One front camera and two side cameras are switchable with a button, so you can inspect around corners without bending the probe. The 5-inch IPS screen is the largest of the four, and the cable length is 16.5 feet. It also has IP67 waterproof lenses with LED illumination, a rechargeable battery that lasts up to 4 hours, and a detachable cable. Limitation: it is used, and the listed price is the highest by a noticeable amount.
Final Recommendation by Use Case
If you want an easy way to start at the lowest listed price and have an Android device handy, choose the KERUI. If you want a screen and dual lenses at a modest listed price, choose the LCD 1080P dual-lens borescope. If you prefer new condition and a long cable with an IPS display, the New 4.3-inch IPS model is the balanced pick. If you need the widest viewing flexibility and a bigger screen, the used DEPSTECH DS520 is worth the higher listed price.
