How to connect a Wi-Fi endoscope to your phone: full instructions with photos and videos

A Wi-Fi endoscope is a compact device with a camera on a flexible cable that transmits images wirelessly to a smartphone or tablet. These gadgets are widely used for car diagnostics, inspecting hard-to-reach areas at home, and even in construction. However, many users encounter problems when first connecting: the device isn't detected, the image is slow, or there's no connection at all. In this article, we'll look into it. all stages of setup — from choosing the right model to solving typical mistakes.

The unique feature of Wi-Fi endoscopes is that they create their own access point (like a router) to which the phone connects. This means that The Internet on your smartphone will be disconnected while the endoscope is operating. — it's important to take this nuance into account. We'll look at the connection using examples of popular models: Borescope Teslong, DEPSTECH DS450 And Anself, but the principles apply to most devices. If your endoscope supports USB-C or Lightning connection, the instructions will differ—we'll cover that as well.

1. Preparation: What you need to connect your endoscope to Wi-Fi

Before using the device for the first time, check the package contents. The box should contain:

• 🔋 The endoscope itself with a camera and flexible cable
• 📱 Charging cable (usually microUSB or Type-C)
• 📄 Instructions (often in English, but with pictograms)
• 🔧 Attachments (mirror, magnet, hook – depending on the model)
• 🎧 Protective case (not included in all kits)

Also, make sure your smartphone meets the minimum requirements:

• 📱 Android 6.0+ or iOS 10.0+ (some features may not work for older versions)
• 📶 Wi-Fi standard support 802.11 b/g/n (most modern phones support it)
• 🔋 Battery charge is at least 50% (the endoscope and phone actively consume power)

If you plan to use an endoscope to inspect a car, prepare the area in advance: clean the surface of dirt and oil, provide good lighting (many models have a built-in backlight, but an additional flashlight is a good idea). For work in dark areas (for example, in ventilation shafts), choose endoscopes with adjustable LED brightness.

⚠️ Attention: Some budget models of endoscopes (For example, no-name from AliExpress) may use non-standard Wi-Fi protocols, which is why they do not connect to smartphones Huawei or Xiaomi With custom firmware. Check compatibility reviews before purchasing.

2. Installing an application to control the endoscope

Most Wi-Fi endoscopes require specialized software to view images. There are no universal apps—each device requires its own software. Here's how to find and install the right program:

1. Check the model name of the endoscope (usually indicated on the body or in the instructions). For example, for DEPSTECH DS450 need an app DEPSTECH, and for Teslong NTS500 — Teslong Scope.

2. Download the app from the official store:

   • 🤖 Google Play for Android
   • 🍎 App Store for iOS

Avoid third-party APK files as they may contain viruses.

Install the program and open it. You may be asked for permission to access the program the first time you run it. camera, files And Wi-Fi - Be sure to provide them.

If you can't find an app by model name, try these universal options:

• 🔍 WiFi Endoscope (suitable for many Chinese devices)
• 🔍 IP Webcam (sometimes works with endoscopes that create an RTSP stream)
• 🔍 Insta360 (for some models with 360° camera)

After installation, don't open the app immediately—turn on the endoscope first. Many programs only begin scanning networks after the device is activated.

3. Turning on the endoscope and creating a Wi-Fi network

Now let's move on to the device itself. The power-on process varies by model, but the general procedure is as follows:

1. Charge the endoscope (if the battery is low). Most models have a charging indicator light; it should be on. red during charging and blue/green after completion.

2. Press and hold the power button (usually 3-5 seconds) until the light blinks blue Wi-Fi indicatorSome endoscopes have a power button combined with a shooting button—see the instructions.

3. Wait for the endoscope to create its own Wi-Fi network. The network name (SSID) usually begins with:

   • 📡 DEPSTECH_XXXX (for DEPSTECH devices)
   • 📡 Teslong_XXXX (for Teslong)
   • 📡 Endoscope_XXXX (for no-name models)

Where XXXX — unique device number.

If the network does not appear:

• 🔄 Restart the endoscope (turn it off and on again).
• 🔋 Check your battery level—if the Wi-Fi module is low, it may not activate.
• 📶 Make sure there are no sources of interference nearby (other Wi-Fi networks, microwaves, Bluetooth devices).

Some endoscopes (eg, Anself AD400) support two operating modes: Wi-Fi Direct (direct connection to the phone) and Hotspot (Creating your own network). The instructions should indicate which mode is used by default. If not, try both.

What to do if the endoscope does not turn on?

If the indicator does not light when you press the power button, check:

1. Charger (use the original cable and 5V/1A power supply).

2. Battery contacts - sometimes they become oxidized (wipe with alcohol).

3. The power button - it may be stuck (gently tap on the case).

If nothing helps, the device may be faulty (a common problem with cheap models).

4. Connecting a smartphone to the endoscope's Wi-Fi network

Once the endoscope has created a network, connect your phone to it:

1. Open Wi-Fi settings on your smartphone.

2. Find the endoscope's network (see the name in the previous section) and connect to it. A password is usually not required, but if it is, try:

   • 🔐 12345678 (standard password for many models)
   • 🔐 88888888 (for some Teslong)
   • 🔐 Look at the sticker under the endoscope battery

Once connected, open the endoscope app. If everything is set up correctly, you will see the image from the camera.

Important nuances:

• 📵 When connected to an endoscope the internet on the phone will be disconnectedTo use the network and the endoscope simultaneously, you need a smartphone with dual Wi-Fi (For example, Samsung Galaxy S22+ or iPhone 15 Pro).
• 🔄 If the image does not appear, restart the app or reconnect to the endoscope's network.
• 📶 The endoscope's Wi-Fi signal is weak - do not move further than 5-10 meters from the device.

On some Android smartphones (especially Xiaomi or Realme) a warning may appear: Network without Internet accessThis is normal - ignore it and click "Connect".

5. Image adjustment and additional functions

Once successfully connected, you can adjust the shooting settings. Most apps offer the following options:

Some endoscopes support digital zoom (zoom), but the quality drops significantly. It's better to physically move the camera closer to the subject. If the image is blurry, check:

• 🔍 Clean the lens (wipe with a soft cloth).
• 🔍 Focal length (usually 3–10 cm from the object).
• 🔍 Lighting (in low light, turn on maximum LED brightness).

A unique feature of some models (such as the DEPSTECH DS600) is their semi-submersible mode. This means the endoscope cable can be submerged in liquid (such as a gas tank), but the camera itself cannot be submerged—it's not waterproof!

6. Typical mistakes and their solutions

Even with a proper connection, problems can still arise. Here are the most common ones and how to fix them:

• 🚫 The endoscope does not create a Wi-Fi network.

  Check the battery charge, restart the device. If that doesn't help, reset the settings (usually there's a button Reset on the body).

• 🚫 The phone connects to the network, but the image is not transmitted.

  Update your endoscope app. If used Android, check permissions (camera and storage access). iPhone Sometimes reinstalling the program helps.

• 🚫 The image is slow or choppy.

  Reduce the resolution in the app settings. Move closer to the endoscope (maximum 5 meters). Close other resource-consuming apps on your phone.

• 🚫 The application returns the error "Failed to connect"

  Try connecting to the endoscope from a different phone. If the problem persists, the device's Wi-Fi module may be faulty.

If the endoscope connects but quickly disconnects, the cause may be:

• 🔋 Low battery (even with 20% charge, Wi-Fi may disconnect).
• 📱 Power saving mode of the phone (disable it in the settings).
• 🌡️ The device is overheating (let it cool for 5-10 minutes).

⚠️ Caution: If the endoscope is used in high-humidity conditions (e.g., for pipe inspection), thoroughly dry the cable and camera after use. Moisture can cause corrosion of the contacts and damage to the device. Some models (e.g., Teslong NTS300P) have a waterproof cable, but the camera is still not sealed.

7. Safety and Lifespan Tips

A Wi-Fi endoscope is not only a useful tool, but also a potentially dangerous one if used improperly. Follow these guidelines:

• ⚡ Avoid working under voltageDo not inspect electrical wiring or power supplies without disconnecting them from the power supply.
• 🔥 Do not point the camera at open flames or hot surfaces. (temperatures above 60°C may damage the lens).
• 🚗 When inspecting the car:
  • Remove the battery terminals before working on electrical components.
  • Do not push the cable into rotating mechanisms (such as a radiator fan).
• 🧹 After use:
  • Wipe the cable and camera with a dry cloth.
  • Store your device in a case, avoiding direct sunlight.

To extend the life of your endoscope battery:

• 🔋 Do not keep the device charging for more than 4–5 hours.
• 🔌 Use only the original cable and adapter.
• 📴 If you do not use the endoscope for more than a month, discharge the battery to 40% before storing.

If you use an endoscope for professional purposes (such as auto diagnostics or plumbing), keep a log of your inspections. Many apps allow you to save reports with date and location information. This will help you track progress (for example, the progression of corrosion in pipes or engine condition).

FAQ: Frequently Asked Questions about Wi-Fi Endoscopes

🔍 Can I connect a Wi-Fi endoscope to a laptop or PC?

Yes, but you'll need a Wi-Fi adapter (if your laptop doesn't have one) and special software. Some endoscopes (e.g., DEPSTECH) support connection via RTSP streamTo view you can use programs like VLC Player or iSpyHowever, it's still more convenient to use a smartphone—mobile apps are optimized for these devices.

📶 Why does the endoscope create its own Wi-Fi network instead of connecting to my router?

Most budget and semi-professional endoscopes operate in the mode access points (AP mode), rather than client (Station mode). This simplifies the design and reduces the cost. If you need an endoscope that connects to an existing network, look for models that support Wi-Fi Station (For example, Teslong NTS500W). They are more expensive, but they allow you to broadcast images to the Internet.

🔋 How long does an endoscope's battery last?

Operating time depends on the model and intensity of use:

• Budget models (for example, no-name from AliExpress): 1–1.5 hours.
• Middle class (DEPSTECH DS450): 2–3 hours.
• Professional (Teslong NTS500): 4–6 hours.

When actively recording video, the battery drains faster. We recommend having a power bank on hand.

📱 Can I use the endoscope without the app?

Technically yes, if the endoscope supports the protocols RTSP or ONVIFIn this case, you can connect to its Wi-Fi network and open the stream in a browser or player (for example, at the address rtsp://192.168.1.1:554/live). However, without the proprietary software, you will lose access to camera settings, video recording, and other features. For details, refer to the instructions for your specific model.

🛠️ How to fix an endoscope if it stops turning on?

If the endoscope does not respond to the power button:

1. Try charging it with a different cable and power supply (5V/1A).
2. Press and hold the power button for 10-15 seconds (sometimes this resets frozen software).
3. Disassemble the case (if it is collapsible) and check the battery contacts.
4. If all else fails, the problem lies with the power controller or battery. In this case, it's cheaper to buy a new endoscope than to repair it.

⚠️ Please note: Disassembling the device will void the warranty (if applicable). Many Chinese endoscopes are sold without an official warranty in Russia.
