Choosing a borescope for thermal borescope visual inspection usually comes down to one question: do you want a camera with its own viewer or one that uses the phone already in your hand? The New 4.3" IPS 1920P Borescope sells for $23.99 and comes as a self-contained kit with a long cable. The KERUI 1M Waterproof Endoscope Camera sells for $4.99 and turns your phone into the display. Both can reach dark spaces, but they suit very different workflows.
Quick verdict
For thorough inspections in darker, deeper spaces, the New 4.3" IPS 1920P Borescope is the stronger choice. For quick checks where the phone is already in your hand, the KERUI 1M USB Borescope is the lighter, simpler companion.

Where each product wins
New 4.3" IPS 1920P Borescope - Better when you need to study what you are looking at. Its self-contained viewer and higher-resolution camera make it easier to catch small cracks, and the longer cable means less repositioning.
KERUI 1M USB Borescope - Better when you want something pocket-size. The narrow camera head and short flexible cable work well in tight openings, and using an Android phone keeps the hardware minimal.
Product notes
New Endoscope Camera with Light, Borescope Camera with 4.3" IPS 1920P 16.5 FT
The New Endoscope Camera works like a self-contained inspection station. Its built-in 4.3-inch IPS screen shows the live view without needing a phone, and the 1920P sensor reveals more surface texture than a lower-resolution camera can. The long cable lets you inspect deep inside ducts, walls, or plumbing runs, while the adjustable LEDs help light a dark cavity. The 8mm head is slightly thicker than the KERUI's 7mm head, so a very narrow gap may be harder to enter. It is also the more expensive of the two, but for regular maintenance checks, the dedicated screen and longer reach usually save time.
1M Waterproof Endoscope Camera 6LED 3 In 1 USB Industrial Borescope
The KERUI 1M Waterproof Endoscope Camera is the easy-to-carry option. It connects to an Android phone through a USB/OTG interface, so the phone becomes the display. The adjustable LEDs and waterproof body let you peek into drains and machinery cavities, and the slim head is narrow enough for tight spots. What you give up is reach and resolution: the cable is just 1 meter long, so deep inspection requires repositioning, and the lower-resolution image is acceptable for a quick look but not for fine detail. You also need an OTG cable that supports your phone. If you only need an occasional visual check, this compact design is a practical choice.
Final choice by use case
Choose the New 4.3" IPS 1920P Borescope when you want a self-contained viewer, sharper detail, and deeper reach. Choose the KERUI 1M USB Borescope for compact, short-range checks with an Android phone.
