Android-Compatible Borescope Cameras for Easy, Accurate Inspections
Use your Android phone as the screen — by USB cable or over Wi-Fi
These borescopes use your Android phone or tablet as the display, so there is no separate monitor to buy or charge. Connect by cable — USB-C, Micro-USB or USB-A, depending on the model — or over Wi-Fi with no cable to the phone.
Most models here are rifle borescopes with 26-inch rigid or 45-inch flexible probes for barrel inspection. The WF150D39L3 is a general-purpose camera with a 3.9 mm, 9.8 ft probe for engines, walls and machinery.

Buying guide
How to Choose a Borescope for Android
Make sure it connects to your phone, then choose the probe for what you inspect.
Check Your Phone's Port
USB-C models such as the NTG100-C and NTG100H-C plug straight into a USB-C Android phone; the NTG100-C lists Android 4.4 and up. The NTG100H uses a USB-A/Micro-USB cable with a USB-C adapter included.
Cable or Wi-Fi
A cable connection needs no wireless setup. Wi-Fi models — the NTG150HW and WF150D39L3 — have no cable to the phone and also list Apple devices, which helps if your household mixes Android and iPhone.
Rigid, Flexible or Folding Probe
A 26-inch rigid probe goes straight down a rifle barrel. The NTG100-C's 45-inch flexible probe reaches further, and the NTG200H's rigid probe folds to 14 inches for a range bag.
Caliber & Mirrors
The 5 mm probes fit .20 or .22 caliber and up, depending on the model. Side-view mirrors let you look at the bore wall; the NTG100-C and NTG100H-C include six mirrors for .22 to .40 caliber.

FAQ
Frequently Asked Questions
Common questions about using a borescope with an Android phone.
Will a Teslong borescope work with my Android phone?
Check how your phone connects. USB-C Android phones can plug straight into the NTG100-C (listed for Android 4.4 and up) or the NTG100H-C. The NTG100H connects with a USB-A/Micro-USB cable and includes a USB-C adapter. The NTG150HW and WF150D39L3 connect over Wi-Fi and list Android and Apple devices, so the phone's port does not matter.
Do I need an app to use a borescope on Android?
Yes. The picture appears in a camera app on your phone. Install the app named in your model's user manual, connect the borescope by cable or Wi-Fi as described, and allow camera access when prompted.
Should I choose a USB or Wi-Fi borescope for Android?
A USB cable is the simplest connection: plug in and open the app, with no wireless setup. Wi-Fi models such as the NTG150HW have no cable between the probe and the phone, so you can hold the phone wherever is easiest to see, and they also list Apple devices if you switch phones later.
Can I also use these borescopes with a Windows PC?
Some can. The NTG100H lists Android, Windows PC and Apple OS X; the NTG100-C and NTG100H-C list Windows as well as Android and USB-C iPhones. Check the product page for the exact operating system versions before buying.
Do they work with iPhone too?
The NTG100-C lists iPhone 15 and newer, and the NTG100H-C works with iPhone 15/16 and USB-C iPads through its USB-C cable. The Wi-Fi NTG150HW and WF150D39L3 list Apple and Android devices. For an iPhone-focused range, see our borescopes for iPhone.
What calibers do these rifle borescopes fit?
The NTG100H-C and NTG200H fit .20 caliber and larger barrels; the NTG100H and NTG150HW fit .22 caliber and larger. The side-view mirror you use also sets the minimum caliber: the NTG100-C and NTG100H-C include six mirrors covering .22 to .40 caliber.
Not Sure It Will Work with Your Phone?
Tell us your phone model and what you want to inspect, and we'll confirm which borescope connects to it.
Borescope Cameras for Android Phones and Tablets
An Android borescope turns the phone in your pocket into the inspection screen. Instead of buying a camera with its own monitor, you connect a probe to your Android phone or tablet, open the app and see the picture live, then save photos and video to the phone to share or compare later.
USB-C, Micro-USB or Wi-Fi
Most models in this collection connect by cable. The NTG100-C and NTG100H-C plug straight into a USB-C Android phone and also include a USB-A/Micro-USB cable, the NTG100H uses USB-A/Micro-USB with a USB-C adapter, and the NTG200H ships with a USB-A/Micro/USB-C cable. If you would rather not plug into the phone, the NTG150HW and WF150D39L3 connect over Wi-Fi and list both Android and Apple devices.
Rifle Barrels and General Inspection
For firearms, choose a 26-inch rigid probe for a straight look down the bore, the NTG100-C's 45-inch flexible probe, or the NTG200H, which folds to 14 inches and has adjustable focus. Side-view mirrors show the throat, rifling and chamber. For engines, walls and machinery, the WF150D39L3 has a 3.9 mm probe on a 9.8 ft cable. Every model comes with a 12-month warranty, free US shipping over $199 and a 30-day money-back guarantee.
