Wi-Fi Inspection Cameras
Stream live video to your iPhone or Android phone over Wi-Fi
A Wi-Fi endoscope sends live video from the camera probe to your phone or tablet, so nothing plugs into the phone and you can hold the screen wherever it is easiest to see. Every in-stock model lists compatibility with Apple and Android mobile devices.
Choose by the job: a 3.9 mm probe for tight gaps, a 16.4 ft probe on a pistol grip for longer reach, or a 26-inch rigid probe for rifle barrels.

Buying guide
How to Choose a Wi-Fi Endoscope
Wi-Fi models trade a cable to the phone for a wireless link. Choose the probe for the job first.
Probe Diameter
A slimmer probe fits smaller openings. The WF150's 3.9 mm probe goes into tight gaps; the WF200's 7.0 mm probe is sturdier and comes on a longer cable; rifle borescopes use a 5.0 mm probe sized for barrels.
Probe Length & Stiffness
The WF150 has a flexible 9.8 ft cable and the WF200 a 16.4 ft cable. For barrels, a 26-inch rigid probe goes in straight.
Your Phone & the App
All in-stock models list compatibility with Apple and Android mobile devices. Setup steps differ by model, so follow the instructions and app named in the manual for the camera you choose.
Image Resolution & Lighting
The WF150 and WF200 capture 1920x1080 photos and video; the NTG150HW records at 1280x720 with a fixed focus suited to close-range barrel work. All have adjustable LEDs, and the WF200 adds a 1-watt work light.

FAQ
Frequently Asked Questions
Common questions about wireless endoscopes and connecting them to your phone.
How does a Wi-Fi endoscope connect to my phone?
The camera sends live video over Wi-Fi to an app on your phone or tablet, so there is no cable between the camera and the phone. Charge the camera, switch it on, connect your phone as described in the model's user manual and open the app to see the picture. Setup steps differ between models, so follow the manual for the camera you buy.
Do these wireless endoscopes work with iPhone and Android?
Yes. The WF150D39L3 and NTG150HW list compatibility with Apple and Android mobile devices, and the WF200 lists iOS and Android. Because the link is wireless, the phone's charging port (Lightning or USB-C) does not matter.
Should I buy a Wi-Fi or a USB endoscope?
A USB endoscope plugs into the phone's port and needs no wireless setup, but you must check that your phone's port and system are supported. A Wi-Fi endoscope has its own battery and connects wirelessly, so you can hold or mount the phone wherever it is easiest to see and your phone's port type does not matter. See our USB endoscopes if you prefer a wired connection.
Which Wi-Fi endoscope should I choose?
For tight openings such as small engine ports, choose the WF150D39L3 with its 3.9 mm probe and 9.8 ft cable. For longer reach into walls, ducts or under vehicles, the WF200 has a 7.0 mm probe on a 16.4 ft cable and a pistol grip with a phone mount. For rifle barrels, the NTG150HW has a 26-inch rigid probe that fits .22 caliber and larger.
Can I take photos and record video?
Yes. The WF150D39L3 and WF200 capture photos and video at up to 1920x1080, and the NTG150HW at 1280x720. You capture them in the app on your phone or tablet, so they are ready to share.
How long does the battery last?
The WF150D39L3 uses an 1800 mAh battery and the WF200 a 2000 mAh battery; both are listed at up to 4 hours. Both charge over USB-C. The NTG150HW has a built-in battery.

Questions about choosing your camera
Do all models use the same app?
Do not assume that one app or operating-system version works with every model. Follow the instructions for the exact product. WF150 lists compatibility with Apple and Android mobile devices; confirm WF200 setup requirements from its current manual.
Is a rifle borescope the same as a general inspection camera?
Both can transmit over Wi-Fi, but they are designed for different inspection tasks. Compare the camera, probe shape and intended use before selecting a model.
