How to connect a Wi-Fi endoscope to an Android phone: complete instructions with troubleshooting

Wireless endoscopes with support Wi-Fi have become indispensable assistants for car diagnostics, inspecting hard-to-reach places at home, and even for professional tasks. However, many users encounter difficulties when first connecting such a device to a smartphone. AndroidProblems arise due to the variety of endoscope models (Borescope, Depstech, Teslong etc.), operating system versions and network settings features.

In this article we will look at step-by-step connection algorithm, typical errors (for example, when the phone doesn't see the endoscope's network or the image isn't transmitted), and we'll also provide recommendations for optimizing the connection for stable operation. We'll pay special attention to compatibility with different versions of Android and the nuances of setting up routers if you plan to use the endoscope via a local network.

Before you begin, make sure your endoscope is charged—a dead battery can interrupt the pairing process. Also, check if your device supports access point mode (AP Mode), as some budget models only work via a direct connection to a smartphone.

1. Preparing the endoscope and smartphone for connection

Before pairing your devices, there are a few mandatory steps to take. First, Turn on the Wi-Fi endoscope — usually you need to hold the power button for 2-3 seconds until the indicator lights up (usually blue or green). Some models (for example, Depstech DW49) are activated automatically when connected to a power source.

Secondly, check compatibility of your smartphoneEndoscopes are usually operated with Android 5.0 and above, but for stable video transmission, the version recommended is 7.0+On devices with Android 10+ There may be problems with location permissions (more on this in the errors section).

Third, install official application From the endoscope manufacturer. Most brands offer their own programs:

• 🔹 Depstech — Depstech or Inspicam (for models DW49, DW51)
• 🔹 Teslong — Teslong WiFi Viewer
• 🔹 Borescope — WiFi Endoscope or Borescope Camera
• 🔹 Universal Apps — IP Webcam (for advanced users)

If you haven't found an app for your model, try universal options, but keep in mind that they may not support all features (for example, video recording or brightness adjustment).

2. Step-by-step connection instructions

Now let's move on to the pairing process itself. Follow the instructions strictly in order to avoid common mistakes.

1. Activate Wi-Fi on the endoscope. Most models have a separate button for this (often labeled Wi-Fi or AP). After clicking, the indicator should light up and the new network should appear in the list of available connections on the phone.
2. Connect to the endoscope network. Open the Wi-Fi settings on your smartphone and find the network with the type name Depstech_XXXX, Borescope_XXXX or Teslong_XXXX. A password is usually not required (or is specified in the instructions as 12345678, 88888888).
3. Launch the application. Once connected, open the installed program. In most cases, the image from the endoscope's camera will appear automatically. If not, click the button. Connect or Start in the interface.
4. Adjust video settings (optional). You can change the resolution in the application (for example, 1280×720 or 1920×1080), brightness, contrast and turn on recording.

If the image does not appear, check:

• 🔋 Endoscope battery level (if the battery is low, the connection may be interrupted).
• 📶 Signal quality - the distance between the smartphone and the endoscope should not exceed 10 meters (ideally 3–5 meters).
• 🔄 Restart both devices and try connecting again.

3. Common mistakes and their solutions

Even when following the instructions correctly, users often encounter problems. Let's look at the most common ones and how to resolve them.

"No Internet Access" Error - is a normal phenomenon, since the endoscope creates local network, but doesn't connect to the internet. Android may display this warning, but you can ignore it. If it's bothersome, disable notifications for this network in your Wi-Fi settings.

Important: On Android 10 and above, the system may request geolocation access when connecting to the endoscope's network for the first time. This is a security requirement; without permission, the connection will be blocked. Allow access temporarily (only while working with the endoscope).

Why does Android 10+ require location services for Wi-Fi?

With Android 10, Google has tightened its security policy. Location permission is now required to connect to any network (including local ones, like an endoscope). This is due to the risk of device tracking via MAC addresses. This permission can be revoked after use.

4. Connecting an endoscope via a router (for advanced users)

If you need to control the endoscope over a long distance (for example, to inspect a roof or basement), you can connect it to local network via a routerThis method is more complicated, but it allows you to broadcast the image to several devices simultaneously.

To do this:

1. Connect the endoscope to the router via an Ethernet cable (if the model supports it) or set it up in mode Station Mode (if there is such an option in the menu).
2. Find out the IP address of the endoscope on the network (usually indicated in the instructions or on the device sticker).
3. On your smartphone, connect to the same router as the endoscope.
4. In the application, enter the IP address of the endoscope manually (in the section Manual Connection or similar).

⚠️ Attention: Not all endoscope models support this mode. Before purchasing, check the specifications to see if this feature is available. Wi-Fi Station Mode or Ethernet.

Also, please note that this type of connection may cause image lag (lag) of up to 1-2 seconds due to data processing by the router. For critical tasks (such as engine diagnostics), it's better to use a direct connection.

5. Optimize the connection for stable operation

To avoid connection drops and image freezes, follow these recommendations:

• 📵 Disconnect other devices from the endoscope's power supply. Connecting multiple gadgets at the same time may cause interference.
• 🔋 Use an external battery. Endoscopes drain quickly when actively transmitting video—connect a Power Bank for extended operation.
• 📶 Select a Wi-Fi channel with minimal interference. In the router settings (if you are connecting through it), select the channel 1, 6 or 11 - they intersect the least.
• 🖥️ Close background apps on your smartphone. Messengers and social networks can consume resources, which leads to lags.

If the image is lagging, try lowering the resolution in the app settings. For example, instead of 1080p select 720p - this will reduce the load on the network.

6. Compatibility with different Android versions

Endoscope manufacturers don't always keep up with the latest Android versions. Below is a compatibility table for popular models:

⚠️ Attention: On devices with Android 12 and later Some endoscopes may not work due to changes in Wi-Fi security policy. If your model doesn't support the new OS, try using compatibility mode (if available in the app settings) or connect the endoscope via OTG adapter (for models with USB output).

7. Alternative connection methods (without Wi-Fi)

If your endoscope does not support Wi-Fi or is experiencing insurmountable connection issues, consider alternative options:

• 🔌 USB endoscopes. Connect via OTG cable Directly to your smartphone. They work without delays, but require your phone to support OTG.
• 📡 Bluetooth endoscopes. Rarely found, but suitable for simple tasks (eg. Borescope Bluetooth 4.0). Image quality is lower than that of Wi-Fi models.
• 🖥️ Connecting to a PC. Some endoscopes (eg, Teslong) can be connected to a computer via USB or Ethernet, and then the image can be transmitted to the phone via a local network.

For USB endoscopes, you will need to install additional software, for example:

For Android: "USB Camera" or "OTG View"
For PC: "Amcap" or "Debut Video Capture"

The advantage of USB solution is no lags and dependence on the endoscope's battery (powered by a phone or PC). A disadvantage is the limited cable length (usually up to 1.5 meters).

8. Review of popular applications for working with an endoscope

Choosing the right app can significantly improve your endoscope experience. Let's look at the most popular options:

For professional use we recommend Inspicam - it supports simultaneous connection of multiple cameras and allows you to save reports with location-based reporting. For everyday tasks, the manufacturer's standard app is sufficient.

❓ How do I know if my smartphone supports OTG for a USB endoscope?

To check OTG support:

1. Connect an OTG cable with a flash drive or mouse to your phone.
2. If the device is detected, OTG is supported.
3. You can also install the application USB OTG Checker from Google Play.

The list of smartphones with OTG support is usually indicated in the specifications on the manufacturer's website.

❓ Why is the image from the endoscope mirrored or inverted?

This is a standard feature of many endoscopes—it allows for easier inspection of parts from different angles. To restore normal viewing:

• Find the button in the app Flip or Mirror.
• On some models, you need to physically rotate the camera (if it is on a flexible cable).

If the option is missing, try another application (for example, IP Webcam).

❓ Can I use an endoscope without a phone?

Yes, some models support:

• Connecting to PC via USB or Ethernet.
• Sign up for built-in memory card (if there is a microSD slot).
• Outputting the image to monitor via HDMI (for professional endoscopes).

Check your model's specifications for these features.

❓ How can I increase the range of my endoscope's Wi-Fi?

To increase the range:

• Use Wi-Fi amplifier (repeater).
• Connect the endoscope to a router with a powerful transmitter (for example, TP-Link Archer C6).
• Reduce video resolution in the application settings.
• Use directional antenna (if the endoscope supports replaceable antennas).

The maximum range under ideal conditions is up to 20 meters, but in practice it rarely exceeds 10 meters.

❓ What should I do if the endoscope stops connecting after an Android update?

The problem is typical for transitions to Android 10+Solutions:

1. Roll back to the previous OS version (if possible).
2. Usage developer mode to disable Wi-Fi restrictions.
3. Installation alternative application (For example, IP Webcam).
4. Connection via USB-OTG (if the model supports it).

If nothing helps, contact the manufacturer for updated firmware for the endoscope.
