修复 AV 到 IP 编码器的 4G 远程访问问题

为什么您的 AV 转 IP 编码器可以在 Wi-Fi 上工作，但不能在 4G 上工作 - 以及如何修复它 (P2P设置指南)

Many users who previously purchased our standard AV-to-IP video encoder board later added the 4G/Wi-Fi module for mobile remote access. A common situation is:

• The encoder works perfectly on local Wi-Fi
• 该 R380 mobile APP also works via Wi-Fi
• But via 4G mobile internet, the R380 APP cannot find the camera
• Local streaming works, 但 remote 4G access fails

If this is happening to you, the reason is simple:

Your original AV-to-IP encoder board was designed for LAN access via wired Ethernet.
After adding a 4G/Wi-Fi module, the encoder must be configured with a P2P server, a unique User ID, and a password so that the mobile APP knows which device to connect to over the internet.

Below is the complete solution.

Root Cause: Missing P2P Server Configuration

When you use Wi-Fi, everything is on the same local network, so the APP can detect the encoder automatically.

But when using 4G mobile networks:

• Your smartphone and the encoder are not on the same LAN
• The encoder must register itself to a P2P cloud server
• The mobile APP must log in using a unique User ID & 密码
• Only after this registration can the APP discover the encoder over 4G

If the encoder’s P2P settings are empty, the R380 app cannot find it through mobile internet.

Step-by-Step Solution: How to Configure the P2P Server

第一, introduce a user’s simple operation way.

你好. This information may be useful. I was unable to program the first and second boards using the as you suggested. I used a different method. I connected the board to the computer via a router and 192.168.1.188. 然后 . In the window that opened, I set the settings. Then and . Everything worked!

Follow these steps to correctly set up P2P on your AV-to-IP encoder board.

1. Install the “IP Search” Tool on Windows

If you don’t have the IP search tool, download it here:

Download IP Search Tool:
https://drive.google.com/file/d/13juxfwvqjsFaRCv7XUkWE2XFSz6sE5kf/view?usp=sharing

Install and run it on a Windows PC.

2. Click “Search” to Find Your Encoder Device

Connect the encoder using a LAN cable to your PC or to the same router.

按 搜索 → Your encoder hardware will appear in the list.

---

3. Configure the P2P Server

In the encoder’s configuration window, 找到 P2P settings section.

You need to enter the following:

• 用户身份 (provided by us — globally unique)
• 密码 (provided by us)
• P2P URL:
  https://connect.peergine.com/

If you don’t have a User ID & password yet, please contact us — each encoder requires a unique ID.

---

4. Click “Setup” to Write the Configuration

按 设置.

The encoder will automatically reboot.

This is normal.

---

5. Wait a Few Minutes, Then Verify

After rebooting:

1. Open the IP Search tool again
2. 点击 搜索 to rediscover the encoder
3. 点击 得到 to read back the settings

If you see the same User ID, 密码, and P2P URL you entered:

✔ P2P configuration is successful

If the fields are blank or failed to update:

✘ The ID might be used by another device
→ Contact us for a new unique User ID

Or simply repeat the steps again.

After Setup — R380 APP Should Work Over 4G

正确配置 P2P 后:

• Your encoder will automatically register to the P2P server
• Your R380 app will log in and locate the encoder from 任何地方
• Wi-Fi and 4G will both work

This solves 99% of cases where local Wi-Fi works but 4G mobile connection fails.

结论

If your AV-to-IP encoder works on Wi-Fi but not via 4G using the R380 APP, the most likely reason is missing P2P configuration on the encoder board.

By following the steps above to set the P2P server, 用户身份, and password, your device will be discoverable anywhere over the mobile network.
