Endoscopes have long ceased to be exclusively medical equipment - today these compact devices with a flexible cable and a miniature camera are used by auto mechanics, plumbers, engineers and even home craftsmen. But here’s the problem: having bought an endoscope, many people encounter difficulties when trying to display an image on a laptop screen. Either the drivers are not installed, or the picture is slow, or the device is not detected by the system at all.

In this article we will look at all possible ways to connect an endoscope to a laptop - from a simple USB connection to wireless solutions, and we’ll also tell you how to avoid common mistakes. You will learn which software is best to use for Depstech, Borescope or Sofirn, how to adjust the resolution and frame rate, and what to do if the laptop “does not see” the device. We will pay special attention Compatible with Windows 11 and macOS Ventura/Sonoma, where problems with driver signing often occur.

1. What endoscopes can be connected to a laptop?

Not all endoscopes support connection to a PC - it all depends on data interface and the availability of appropriate connectors. Here are the main types of devices that are compatible with laptops:

  • 🔌 USB endoscopes - the most common models (Depstech DW49, Sofirn SF10). Connect directly via port USB-A or USB-C, often do not require additional power.
  • 📡 Wi-Fi endoscopes — transmit images over a wireless network (Borescope Teslong, YINAMA). You need to connect to the device's access point like a router.
  • 🖥️ HDMI endoscopes — professional models with output HDMI or AV (Olympus IPLEX, GE Inspection). Requires an adapter to connect to a laptop.
  • ⚡ Hybrid models - combine USB for power and Wi-Fi for data transfer (Anself, VANTA).

Important: endoscopes with their own screen (For example, Kingsong or LCD borescopes) usually not intended to connect to a PC. They can only be used autonomously. If your model does not have one of the interfaces listed, it is most likely not compatible with your laptop.

2. Preparing the laptop before connecting

Before pairing your endoscope with your laptop, there are a few critical steps you should take. This will save you from 80% of compatibility problems:

⚠️ Attention: If you connect the endoscope to a laptop on Windows 11 with the function enabled Secure Boot, the drivers may not install. Disable this option in the BIOS or use signed drivers from the manufacturer.
  • 🔄 Update your OS - check for updates in Settings → Windows Update (or System settings → Software update on macOS).
  • 🚫 Disable your antivirus - programs like Kaspersky or Avast may block driver installation.
  • 🔌 Check the ports - if you have USB 3.0 (blue connector), but the endoscope only supports USB 2.0, use an adapter.
  • 📥 Download the software in advance - most endoscopes require programs like Amcap, Depstech Viewer or VLC (for Wi-Fi models).

For macOS additional installation may be required Homebrew and drivers libusb via Terminal:

brew install libusb

brew install --cask vlc

Update your operating system to the latest version

Disable antivirus software during installation

Download the official software from the endoscope manufacturer’s website

Prepare adapters (USB-C → USB-A, HDMI → USB-C, etc.)

Check for free disk space (minimum 500 MB) -->

3. Connecting a USB endoscope: step-by-step instructions

USB endoscopes are the easiest option for connecting to a laptop. However, even here there are nuances, especially if the device is not detected automatically. Follow this algorithm:

  1. Connect the endoscope to your laptop via cable USB-A or USB-C (depending on model). Use the original cable - cheap Chinese analogues may not transmit data.
  2. Wait for the drivers to install. Windows usually finds them automatically, but if this does not happen, download the driver from the manufacturer's website (for example, for Depstech — official page).
  3. Launch the viewer:
    • For Windows: Amcap, Depstech Viewer or PotPlayer.
    • For macOS/Linux: VLC, Cheese or Guvcview.
  • Adjust image settings in the program: resolution (usually 1280×720 or 1920×1080), frame rate (30 FPS or 60 FPS), white balance.

    • If the image is slow or torn, try:

    • 🔌 Connect the endoscope to the port USB 3.0 (blue connector).
    • 🖥️ Reduce the resolution in the program settings to 640×480.
    • 🔄 Disable other USB devices (web cameras, flash drives).
    💡

    If the endoscope is not detected on Windows, try installing it in compatibility mode for Windows 7. To do this, right-click on the driver file → Properties → Compatibility → Run the program in compatibility mode for Windows 7.

    4. Connecting the Wi-Fi endoscope to a laptop

    Wireless endoscopes are convenient because they are not tied to cable length, but they require more steps to set up. The main difficulty is to correctly connect to the device’s network and configure video transmission.

    Instructions for Wi-Fi endoscopes (Teslong, YINAMA, Anself):

    1. Turn on the endoscope and wait for it to create its own access point. Usually its name begins with the model, for example Teslong_XXXX.
    2. Connect your laptop to the endoscope's Wi-Fi:
      • On Windows: Start → Settings → Network and Internet → Wi-Fi.
      • On macOS: Wi-Fi icon on the menu bar → select the endoscope network.

      The password is usually specified in the instructions (often this 12345678 or empty field).

    3. Launch the viewer:
      • Official software from the manufacturer (for example, Teslong Viewer).
      • Universal Applications: VLC (open stream at rtsp://192.168.1.1:554/live) or IP Camera Viewer.
  • Adjust latency and quality. In wireless mode, the delay can reach 0.5–1 second. To reduce it, lower the resolution to 640×480.
    • ⚠️ Attention: When connected to the endoscope's Wi-Fi, the laptop will lose access to the Internet. To avoid this, use USB-Wi-Fi adapter (For example, TP-Link TL-WN725N) for simultaneous connection to two networks.
    Endoscope model Connection type Recommended Software Max. resolution
    Depstech DW49 USB 2.0 Depstech Viewer, Amcap 1920×1080
    Teslong NTS500 Wi-Fi (2.4 GHz) Teslong App, VLC 1280×720
    Sofirn SF10 USB-C PotPlayer, OBS Studio 1920×1080@60FPS
    YINAMA Wi-Fi + USB (power) YINAMA Viewer 1280×720

    5. Connecting professional HDMI endoscopes

    Professional endoscopes (Olympus, GE Inspection, Karl Storz) are usually equipped with an outlet HDMI or SDI. Connecting them to a laptop requires additional equipment - external video capture card.

    You will need:

    • 🔧 Capture board - for example, Elgato Cam Link 4K, Magewell USB Capture HDMI or Blackmagic Design Intensity Shuttle.
    • 🔌 HDMI cable (or adapter SDI → HDMI, if the endoscope has a connector BNC).
    • 💻 Capture program: OBS Studio, VLC or specialized software from the board manufacturer.

    Step by step instructions:

    1. Connect the endoscope to the capture board via HDMI.
    2. Connect the board to the laptop via USB 3.0 or Thunderbolt.
    3. Install drivers for the capture board (download from the manufacturer’s website).
    4. Run OBS Studio and add source Video capture deviceby selecting your board.
    5. Adjust the resolution and frame rate to suit the endoscope's capabilities (e.g. 1920×1080@30FPS).
    ⚠️ Attention: Capture boards like Elgato Cam Link do not work with endoscopes that use HDCP protection (for example, some medical models). In this case, you will have to use professional solutions from Blackmagic Design or AJA.
    What should I do if the capture board does not detect the endoscope?

    1. Check if the board supports input signal with the resolution of your endoscope (eg Elgato Cam Link 4K doesn't work with 4K@60FPS via HDMI 1.4).

    2. Try a different HDMI cable (preferably certified High Speed).

    3. Update the capture board firmware using the manufacturer's official software.

    4. If the endoscope gives a signal SDI, use a converter SDI → HDMI (For example, Blackmagic Mini Converter).

    6. Solving common connection problems

    Even if connected correctly, the endoscope may not work correctly. Here are the most common problems and their solutions:

    Problem Possible reason Solution
    The endoscope is not detected Drivers are missing Download the driver from the manufacturer's website and install manually via Device Manager
    The image is slow Lack of USB port resources Connect to USB 3.0, disable other devices, lower resolution
    No sound (if supported) Incorrect settings in the program B Amcap or VLC choose the right audio device
    Wi-Fi endoscope does not connect Frequency mismatch (2.4 GHz vs 5 GHz) Switch the router to 2.4 GHz or use an adapter
    Color reproduction is distorted Wrong white balance Calibrate manually in the program settings (for example, in Depstech Viewer)

    If the endoscope is defined as Unknown device in Device Manager, follow these steps:

    1. Right click on the device → Update driver → Search for drivers on this computer.
    2. Select Select a driver from the list of available ones → Imaging devices.
    3. If a suitable driver is not listed, click Install from disk and specify the path to the downloaded file .inf.
    💡

    If the endoscope is unstable on Windows 11, try disabling the feature Memory Integrity in Windows Security → Device Security → Kernel Isolation Details. This often solves driver signing problems.

    7. Software for working with the endoscope

    Not only the image quality, but also the available functions depend on the selected software: recording video, taking pictures, adjusting exposure, etc. Here are the best programs for different tasks:

    • 🎥 For easy viewing:
      • Amcap — standard software for USB cameras, supports brightness and contrast settings.
      • VLC - universal player, opens streams via RTSP (for Wi-Fi endoscopes).
    • 📸 For recording and processing:
      • OBS Studio — allows you to record video in high quality with text overlay.
      • Depstech Viewer — proprietary software with the function of measuring objects in the image.
    • 🔍 For professional analysis:
      • IP Camera Viewer - supports multiple cameras simultaneously.
      • Guvcview (Linux/macOS) - open source, flexible settings.

    If you need measure objects in the image (for example, cracks in parts), use Depstech Viewer or Teslong Measure. These programs allow you to calibrate a scale to a known object size (such as the diameter of a bolt) and then measure distances to the nearest millimeter.

    For macOS the best choice would be VLC or QuickTime Player (for USB endoscopes). If you need advanced features, try Webcam Settings from App Store.

    8. Tips for improving image quality

    Users often complain about blurry or dark images from the endoscope. Here's how to improve your picture without buying a new device:

    • 💡 Lighting:
      • Use the endoscope's built-in illumination (usually 6–8 LEDs).
      • If there is not enough light, add an external source (for example, LED flashlight on a flexible holder).
    • 🔍 Focus:
      • Rotate the focusing ring on the endoscope lens (if equipped).
      • For fixed focus, adjust the distance to the subject (usually 3-10 cm).
    • 🎛️ Program settings:
      • Enlarge exposition And ISO in the camera settings (but do not overdo it - noise will appear).
      • Turn off automatic white balance and adjust it manually.
    • 🔌 Hardware improvements:
      • Use USB 3.0 to reduce latency.
      • If the cable is long, use an extension cord with a signal repeater.

    For video recording in high quality, customize in OBS Studio the following parameters:

    Формат: MP4

    Битрейт: 10–15 Mbps
    

    Кодеки: H.264 (x264)
    

    Разрешение: 1920×1080 (если поддерживается)
    

    FPS: 30 (или 60, если эндоскоп позволяет)

    💡

    If the image is noisy (lots of artifacts), try decreasing the value ISO in the camera settings and add external light. The noise is especially noticeable when shooting in dark spaces (like a car engine).
