 ## Security
 
+> [!IMPORTANT]
+> If an attacker gains access to the API, you are in danger. Through the API, an attacker can use insecure sources such as echo and exec. And get full access to your server.
+
+For maximum (paranoid) security, go2rtc has special settings:
+
+```yaml
+app:
+  # use only allowed modules
+  modules: [api, rtsp, webrtc, exec, ffmpeg, mjpeg]
+
+api:
+  # use only allowed API paths

 By default, `go2rtc` starts the Web interface on port `1984` and RTSP on port `8554`, as well as uses port `8555` for WebRTC connections. The three ports are accessible from your local network. So anyone on your local network can watch video from your cameras without authorization. The same rule applies to the Home Assistant Add-on.
 
 This is not a problem if you trust your local network as much as I do. But you can change this behaviour with a `go2rtc.yaml` config:

-## FAQ
-
-**Q. What's the difference between go2rtc, WebRTC Camera and RTSPtoWebRTC?**
-
-**go2rtc** is a new version of the server-side [WebRTC Camera](https://github.com/AlexxIT/WebRTC) integration, completely rewritten from scratch, with a number of fixes and a huge number of new features. It is compatible with native Home Assistant [RTSPtoWebRTC](https://www.home-assistant.io/integrations/rtsp_to_webrtc/) integration. So you [can use](#module-hass) default Lovelace Picture Entity or Picture Glance.
-
-**Q. Should I use the go2rtc add-on or WebRTC Camera integration?**
-
-**go2rtc** is more than just viewing your stream online with WebRTC/MSE/HLS/etc. You can use it all the time for your various tasks. But every time Hass is rebooted, all integrations are also rebooted. So your streams may be interrupted if you use them in additional tasks.
-
-Basic users can use the **WebRTC Camera** integration. Advanced users can use the go2rtc add-on or the Frigate 0.12+ add-on.
-
-**Q. Which RTSP link should I use inside Hass?**
-
-You can use a direct link to your cameras there (as you always do). **go2rtc** supports zero-config feature. You may leave `streams` config section empty. And your streams will be created on the fly on first start from Hass. And your cameras will have multiple connections. Some from Hass directly and one from **go2rtc**.
-
-Also, you can specify your streams in **go2rtc** [config file](#configuration) and use RTSP links to this add-on with additional features: multi-source [codecs negotiation](#codecs-negotiation) or FFmpeg [transcoding](#source-ffmpeg) for unsupported codecs. Or use them as a source for Frigate. And your cameras will have one connection from **go2rtc**. And **go2rtc** will have multiple connections - some from Hass via RTSP protocol, some from your browser via WebRTC/MSE/HLS protocols.
-
-Use any config that you like.
-
-**Q. What about Lovelace card with support for two-way audio?**
-
-At this moment, I am focused on improving stability and adding new features to **go2rtc**. Maybe someone could write such a card themselves. It's not difficult, I have [some sketches](https://github.com/AlexxIT/go2rtc/blob/master/www/webrtc.html).

+# Pinggy
+
+[Pinggy](https://pinggy.io/) - nice service for public tunnels to your local services.
+
+**Features:**
+
+- A free account does not require registration.
+- It does not require downloading third-party binaries and works over the SSH protocol.
+- Works with HTTP, TCP and UDP protocols.
+- Creates HTTPS for your HTTP services.
+
+> [!IMPORTANT]
+> A free account creates a tunnel with a random address that only works for an hour. It is suitable for testing purposes ONLY.
+
+> [!CAUTION]
+> Public access to go2rtc without authorization puts your entire home network at risk. Use with caution.
+
+**Why:**
+
+- It's easy to set up HTTPS for testing two-way audio.
+- It's easy to check whether external access via WebRTC technology will work.
+- It's easy to share direct access to your RTSP or HTTP camera with the go2rtc developer. If such access is necessary to debug your problem.
+
+## Configuration
+
+You will find public links in the go2rtc log after startup.
+
+**Tunnel to go2rtc WebUI.**
+
+```yaml
+pinggy:
+  tunnel: http://localhost:1984
+```
+
+**Tunnel to RTSP camera.**
+
+For example, you have camera: `rtsp://admin:password@192.168.1.123/cam/realmonitor?channel=1&subtype=0`
+
+```yaml
+pinggy:
+  tunnel: tcp://192.168.10.91:554
+```
+
+In go2rtc logs you will get similar output:
+
+```
+16:17:43.167 INF [pinggy] proxy url=tcp://abcde-123-123-123-123.a.free.pinggy.link:12345
+```
+
+Now you have working stream:
+
+```
+rtsp://admin:password@abcde-123-123-123-123.a.free.pinggy.link:12345/cam/realmonitor?channel=1&subtype=0

+# Tuya
+
+*[New in v1.9.13](https://github.com/AlexxIT/go2rtc/releases/tag/v1.9.13)*
+
+[Tuya](https://www.tuya.com/) proprietary camera protocol with **two way audio** support. Go2rtc supports `Tuya Smart API` and `Tuya Cloud API`.
+
+**Tuya Smart API (recommended)**:
+- Cameras can be discovered through the go2rtc web interface via Tuya Smart account (Add > Tuya > Select region and fill in email and password > Login).
+- **Smart Life accounts are not supported**, you need to create a Tuya Smart account. If the cameras are already added to the Smart Life app, you need to remove them and add them again to the Tuya Smart app.
+
+**Tuya Cloud API**:
+- Requires setting up a cloud project in the Tuya Developer Platform.
+- Obtain `device_id`, `client_id`, `client_secret`, and `uid` from [Tuya IoT Platform](https://iot.tuya.com/). [Here's a guide](https://xzetsubou.github.io/hass-localtuya/cloud_api/).
+- Please ensure that you have subscribed to the `IoT Video Live Stream` service (Free Trial) in the Tuya Developer Platform, otherwise the stream will not work (Tuya Developer Platform > Service API > Authorize > IoT Video Live Stream).
+
+## Configuration
+
+Use `resolution` parameter to select the stream (not all cameras support `hd` stream through WebRTC even if the camera has it):
+- `hd` - HD stream (default)
+- `sd` - SD stream
+
+```yaml
+streams:
+  # Tuya Smart API: WebRTC main stream (use Add > Tuya to discover the URL)
+  tuya_main:
+    - tuya://protect-us.ismartlife.me?device_id=XXX&email=XXX&password=XXX
+
+  # Tuya Smart API: WebRTC sub stream (use Add > Tuya to discover the URL)
+  tuya_sub:
+    - tuya://protect-us.ismartlife.me?device_id=XXX&email=XXX&password=XXX&resolution=sd
+
+  # Tuya Cloud API: WebRTC main stream
+  tuya_webrtc:
+   - tuya://openapi.tuyaus.com?device_id=XXX&uid=XXX&client_id=XXX&client_secret=XXX
+  
+  # Tuya Cloud API: WebRTC sub stream
+  tuya_webrtc_sd:
+   - tuya://openapi.tuyaus.com?device_id=XXX&uid=XXX&client_id=XXX&client_secret=XXX&resolution=sd

+# Xiaomi
+
+This source allows you to view cameras from the [Xiaomi Mi Home](https://home.mi.com/) ecosystem.
+
+**Important:**
+
+1. **Not all cameras are supported**. There are several P2P protocol vendors in the Xiaomi ecosystem. 
+Currently, the **CS2** vendor is supported. However, the **TUTK** vendor is not supported.
+2. Each time you connect to the camera, you need internet access to obtain encryption keys.
+3. Connection to the camera is local only.
+
+**Features:**
+
+- Multiple Xiaomi accounts supported
+- Cameras from multiple regions are supported for a single account
+- Two-way audio is supported
+- Cameras with multiple lenses are supported
+
+## Setup
+
+1. Goto go2rtc WebUI > Add > Xiaomi > Login with username and password
+2. Receive verification code by email or phone if required.
+3. Complete the captcha if required.
+4. If everything is OK, your account will be added and you can load cameras from it.
+
+**Example**
+
+```yaml
+xiaomi:
+  1234567890: V1:***
+
+streams:
+  xiaomi1: 	xiaomi://1234567890:cn@192.168.1.123?did=9876543210&model=isa.camera.hlc7
+```
+
+## Configuration
+
+You can change camera's quality: `subtype=hd/sd/auto`
+
+```yaml
+streams:
+  xiaomi1: xiaomi://***&subtype=sd
+```
+
+You can use second channel for Dual cameras: `channel=1`
+
+```yaml
+streams:
+  xiaomi1: xiaomi://***&channel=1
+```
