# Wyze
|
||||
|
||||
This source allows you to stream from [Wyze](https://wyze.com/) cameras using native P2P protocol without the Wyze app or SDK.
|
||||
|
||||
**Important:**
|
||||
|
||||
1. **Requires Wyze account**. You need to login once via the WebUI to load your cameras.
|
||||
2. **Requires firmware with DTLS**. Only cameras with DTLS-enabled firmware are supported.
|
||||
3. Internet access is only needed when loading cameras from your account. After that, all streaming is local P2P.
|
||||
4. Connection to the camera is local only (direct P2P to camera IP).
|
||||
|
||||
**Features:**
|
||||
|
||||
- H.264 and H.265 video codec support
|
||||
- AAC, G.711, PCM, and Opus audio codec support
|
||||
- Two-way audio (intercom) support
|
||||
- Resolution switching (HD/SD)
|
||||
|
||||
## Setup
|
||||
|
||||
1. Get your API Key from [Wyze Developer Portal](https://support.wyze.com/hc/en-us/articles/16129834216731)
|
||||
2. Go to go2rtc WebUI > Add > Wyze
|
||||
3. Enter your API ID, API Key, email, and password
|
||||
4. Select cameras to add - stream URLs are generated automatically
|
||||
|
||||
**Example Config**
|
||||
|
||||
```yaml
|
||||
wyze:
|
||||
user@email.com:
|
||||
api_id: "your-api-id"
|
||||
api_key: "your-api-key"
|
||||
password: "yourpassword" # or MD5 triple-hash with "md5:" prefix
|
||||
|
||||
streams:
|
||||
wyze_cam: wyze://192.168.1.123?uid=WYZEUID1234567890AB&enr=xxx&mac=AABBCCDDEEFF&model=HL_CAM4&dtls=true
|
||||
```
|
||||
|
||||
## Stream URL Format
|
||||
|
||||
The stream URL is automatically generated when you add cameras via the WebUI:
|
||||
|
||||
```
|
||||
wyze://[IP]?uid=[P2P_ID]&enr=[ENR]&mac=[MAC]&model=[MODEL]&subtype=[hd|sd]&dtls=true
|
||||
```
|
||||
|
||||
| Parameter | Description |
|
||||
|-----------|-------------|
|
||||
| `IP` | Camera's local IP address |
|
||||
| `uid` | P2P identifier (20 chars) |
|
||||
| `enr` | Encryption key for DTLS |
|
||||
| `mac` | Device MAC address |
|
||||
| `model` | Camera model (e.g., HL_CAM4) |
|
||||
| `dtls` | Enable DTLS encryption (default: true) |
|
||||
| `subtype` | Camera resolution: `hd` or `sd` (default: `hd`) |
|
||||
|
||||
## Configuration
|
||||
|
||||
### Resolution
|
||||
|
||||
You can change the camera's resolution using the `subtype` parameter:
|
||||
|
||||
```yaml
|
||||
streams:
|
||||
wyze_hd: wyze://...&subtype=hd
|
||||
wyze_sd: wyze://...&subtype=sd
|
||||
```
|
||||
|
||||
### Two-Way Audio
|
||||
|
||||
Two-way audio (intercom) is supported automatically. When a consumer sends audio to the stream, it will be transmitted to the camera's speaker.
|
||||
|
||||
