Wireless endoscopes with support Wi-Fi They have become an indispensable tool for car diagnostics, equipment repair, and even household tasks. These compact devices transmit camera images directly to a smartphone screen, eliminating the need for bulky monitors. However, many users encounter difficulties when first connecting: the phone doesn't detect the endoscope's network, the image lags, or the app displays an error. In this article, we'll explore all connection methods — from choosing the right adapter to setting up software on Android And iPhone.
Structurally, a Wi-Fi endoscope is a flexible cable with a camera at the end and a transmitting module that creates its own access point. The main advantage of such models (for example, Borescope Teslong or Depstech DS450>) - no wires between the endoscope and the phone. But herein lies the main difficulty: not all smartphones work correctly with ad-hoc networks (peer-to-peer) companies that create affordable endoscopes. Below, you'll learn how to overcome these limitations and achieve a stable connection.
1. Which endoscopes support Wi-Fi connection?
Not all endoscopes are equipped with a module Wi-Fi is an option found primarily in mid-range and premium models. Cheaper devices (under 2,000 rubles) typically connect via a cable. USB-OTG or Lightning, while wireless options cost from 3,000 rubles and up. Here are the key features of a Wi-Fi endoscope:
- 📡 There is a button on the body to turn on/off the wireless module (often labeled
Wi-FiorAP Mode). - 🔋 A battery is included (endoscopes without Wi-Fi are powered directly from the phone's USB port).
- 📱 The instructions indicate the name of the mobile application for connection (for example, Depstech, Teslong View or WiFi Endoscope).
- 🛠️ There is a logo on the box
Wi-Fi DirectorWireless Endoscope.
Popular models with wireless connectivity include:
- Depstech DS450 - permission
1920×1080, waterproof case, Wi-Fi range up to 10 meters. - Teslong NTS500 - flexible probe 5 mm, support Android And iOS, built-in battery 2200 mAh.
- Borescope V5.0 - 6 LEDs with adjustable brightness, compatible with Windows (via adapter).
If your device isn't on this list, check the specifications on the manufacturer's website. Sometimes, budget models (for example, no-name (The endoscopes from AliExpress) have a Wi-Fi module, but it's unstable due to a weak transmitting chip. In such cases, it's recommended to use external Wi-Fi adapter for a smartphone (we'll talk about it below).
2. Preparing the endoscope and phone for connection
Before connecting devices, complete a few mandatory steps. This will help avoid common errors, such as the endoscope's network not being listed as available or the app not launching.
Charge the endoscope battery (at least 50%).
Make sure Wi-Fi is turned on on your phone.
Close all background apps, especially messengers and streaming services.
Disable VPN and proxy servers (they may block local networks).
Download the official app for your endoscope model.-->
Pay special attention endoscope power supplyIf the battery is discharged below 20%, the Wi-Fi module may work erratically or not turn on at all. In some models (for example, Teslong NTS300) When the battery is low, the red indicator lights up - in this case, connect the device to the charger for 10-15 minutes before use.
On your phone, check the following settings:
- 📵 Airplane mode must be turned off.
- 🔄 Automatic connection to networks (on Android) It is better to turn it off so that the phone does not switch to home Wi-Fi.
- 🛡️ Firewall or antivirus (For example, Avast, Kaspersky) may block connections to local networks - temporarily disable them.
⚠️ Attention: On iPhone iOS versions below 14.0 may have issues connecting to ad-hoc networks (like those created by endoscopes). Update your firmware to the latest version via Settings → General → Software Update.
3. Step-by-step instructions: connecting to Android
Connection process on Android usually easier than on iPhone, thanks to more flexible network settings. Follow these instructions:
- Turn on the endoscope. Press and hold the power button for 3-5 seconds until the blue Wi-Fi light turns on (green on some models).
- Activate the endoscope access point. This may require pressing a separate button.
Wi-Fior hold the power button for 10 seconds (depending on the model). - Find the endoscope network on your phone. Go to
Settings → Wi-Fiand find the network with the type nameEndoscope_XXXX,Depstech_XXXXorTeslong_XXXX(where XXXX is a unique identifier). - Connect to the network. The default password is usually
12345678,88888888or specified in the instructions. If the network isn't listed, refresh the network list (swipe down) or reboot the endoscope. - Launch the application. Open the endoscope program (for example, Depstech View) and wait for the connection. Some apps require you to manually select the device model in the menu.
If the image does not appear:
- 🔄 Restart the endoscope and phone.

| The app returns a "No Signal" error. | Software version incompatibility | Please update your app or download an alternative program (for example, IP Webcam) |
| The image lags or slows down | Interference from other Wi-Fi networks | Turn off your home router or move to another room |
| The endoscope discharges quickly. | The Wi-Fi module consumes a lot of energy. | Connect an external battery (power bank) to the endoscope |
What to do if the endoscope does not turn on?
If the endoscope does not respond to the power button after charging:
1. Check the charging cable - it must support a current of at least 1A.
2. Try charging the device from a computer (USB 3.0 port).
3. If the indicator does not light, the battery may be faulty - contact the service center or the seller (under warranty).
4. In some models (for example, Depstech DS200) there is a "hidden" reset: press and hold the power button for 20 seconds.
4. Connecting to an iPhone: Features and Bypassing Restrictions
On iPhone the connection process is complicated by security policy Apple, which limits access to local networks. Many users encounter a problem where the phone sees the endoscope's network but can't connect to it, or the app won't launch. Here's how to solve this problem:
- Update iOS. Go to
Settings → General → Software Updateand install the latest version. - Use the official app. For iPhone Suitable:
- Depstech View (App Store)
- WiFi Endoscope (universal)

Connectand immediately open the endoscope application.
A critical feature for iPhone: If the endoscope creates a network in the 5 GHz band and your iPhone doesn't support this standard (e.g., iPhone 6 or later), connection will be impossible. In this case, use a 2.4 GHz Wi-Fi adapter or upgrade to a model that supports both bands.
⚠️ Attention: On a jailbroken iPhone, conflicts between tweaks (system modifications) and the Wi-Fi module may occur. If the endoscope doesn't connect, try disabling all tweaks via Cydia or Sileo.
If the application gives an error "Unable to connect to the camera", try:
- 🔄 Restart the endoscope and iPhone.
- 📱 Delete the app and reinstall it.
- 🌐 Connect to the endoscope via another phone (Android) to check its functionality.
5. Alternative connection methods
If the standard method doesn't work, try one of the alternatives. These are especially useful for older smartphones or endoscopes with unstable Wi-Fi.
Method 1: Using an external Wi-Fi adapter
Some endoscopes (eg, Borescope V5.0) support connection via external USB Wi-Fi adapterThis is relevant if:
- Your phone does not see the endoscope's network.
- The endoscope's Wi-Fi module is weak and the signal keeps dropping out.
- You are using iPhone with restrictions on ad-hoc networks.
To do this you will need:
- 🔌 OTG adapter (For Android) or Lightning-to-USB (For iPhone).
- 📡 Wi-Fi adapter with support
SoftAP(For example, TP-Link TL-WN725N). - 📱 Application for managing the adapter (for example, WiFi Analyzer).
Method 2: Connecting via a router
If the endoscope supports the mode Station Mode (and not only AP Mode), it can be connected to a home router. To do this:
- Turn on the endoscope and set it to the mode
Station(usually by long pressing the Wi-Fi button). - Connect the endoscope to your home Wi-Fi network (the password is entered through a special application or web interface).
- Connect your phone to the same router.
- Launch the endoscope app - it should automatically find the device on the local network.
The advantage of this method is a stable signal and the ability to connect multiple devices simultaneously (for example, a phone and a tablet). However, not all endoscopes support Station Mode — check this in the instructions.
Method 3: Using third-party applications
If the endoscope's native app isn't working properly, try these universal apps:
- 📱 IP Webcam (Android) - supports most Wi-Fi cameras.
- 🍎 WiFi Camera (iOS) is an alternative for iPhone.
- 🖥️ VLC Player - can stream video from an endoscope using an IP address (you need to enter
rtsp://[endoscope IP]:554manually).
6. Common mistakes and their solutions
Even with a proper connection, users still encounter common issues. Let's look at the most common ones and how to resolve them.
| Error | Cause | Solution |
|---|---|---|
| The phone connects to the endoscope's network, but the image is not transmitted. | The application is not running or the ports are blocked. | Open the endoscope app and check your firewall settings |
| The image is slow or choppy. | Weak Wi-Fi signal or interference | Reduce the distance between devices or switch to 5 GHz (if supported) |
| The app says "Camera not found" | Software version incompatibility | Please update your app or download another app (for example, WiFi Endoscope Pro) |
| The endoscope heats up quickly. | Overload of the Wi-Fi module or battery | Let the device cool for 10-15 minutes, then continue working. |
If the endoscope is connected, but the image inverted or mirrored, most apps have a correction option. For example, in Depstech View need to:
- Open camera settings (gear in the upper right corner).
- Find an option
Flip ImageorMirror. - Enable/disable it until you get the correct image.
⚠️ Attention: If the endoscope is used to diagnose a vehicle or equipment, avoid operating it in damp conditions (for example, when checking the cooling system). Even waterproof models (IP67) may fail if exposed to liquid for a long time due to corrosion of the contacts.
7. How to improve signal quality and connection stability
An unstable signal is one of the main problems when working with Wi-Fi endoscopes. Here are some ways to improve the connection:
