IP cameras, sometimes called webcams or netcams, let you capture and broadcast live video over the internet. They're often used for video surveillance and security.
You'll need to choose which workflow you'll use, live stream or transcoder, before you begin this task. See Decide between a live stream or transcoder workflow for more information about these workflows.
Before you start
You should be familiar with the following concepts:
- API authentication methods. We use JSON web tokens for API authentication. See Authentication for more information.
- Environment variables. We use environment variables for the API version and your JWT in the cURL API request examples in this topic to make it easier for you to copy, paste, and run commands in your Terminal or Command Prompt window. If you don't set environment variables for these values, you'll need to manually enter the correct values in the code samples throughout this tutorial. See Tools for testing the API for instructions.
You should complete the following tasks:
- Install the latest firmware for your encoder.
You should have access to the following items:
- The encoder's user guide for details about how to operate the device or software and how to specify settings such as resolution, bitrate, and frame rate.
Live stream workflow
1. Create a live stream
Create a live stream that receives a RTSP source, generates a player, and configures a hosted page by sending a POST request to the /live_streams endpoint.
You can use the following sample request, making sure to:
- Set encoder to the type of camera. Valid values include:
- ipcamera for a generic IP camera
- axis for an Axis network IP camera
- sony for a Sony SRG-300SE IP camera
- Set source_url according to your camera type.
- For a generic camera, see your IP camera's user guide for for details about the source_url.
- For an Axis network IP camera, the source_url is in the form
rtsp://[username]:[password]@[ip_address]/axis-media/media.amp. See your Axis camera user guide or the Axis online helpdesk for details about the camera's IP address. - For a Sony SRG-300SE IP camera, the source_url is in the form
rtsp://[camera-ip-address]/video[port]. See the Sony SRG-300SE User's Guide for details about the camera's IP address.
The hostname or IP address used in the source_url must be publicly accessible. If authentication information, such as username and password, is included in the source_url, it can only contain alphanumeric, period (.), underscore (_), and hyphen (-) characters.
- Set broadcast_location to the region that's closest to your video source.
- Change any values unique to your broadcast, using the API reference documentation as a resource. See the API endpoint link below.
Sample request
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ${WV_JWT}" \
-d '{
"live_stream": {
"aspect_ratio_height": 720,
"aspect_ratio_width": 1280,
"billing_mode": "pay_as_you_go",
"broadcast_location": "us_west_california",
"delivery_method": "pull",
"encoder": "ipcamera",
"name": "MyIPCameraLiveStream",
"source_url": "rtsp://camera-ip-address/videoinfo",
"transcoder_type": "transcoded"
}
}' "${WV_HOST}/api/${WV_VERSION}/live_streams"
Sample response
The response includes:
- An ID for the live stream that you'll use in step 3.
- source_connection_information. Because you're pulling video from the camera, you won't need to do anything futher with this information.
{
"live_stream": {
"id": "1234abcd",
"name": "MyIPCameraLiveStream",
...
"encoder": "ipcamera",
...
"source_connection_information": {
"source_url": "rtsp://camera-ip-address/videoinfo",
},
...
}
}
2. Configure your video source
You provided the source_url that gives Wowza Video with a connection to the camera when you created the live stream. Now, make sure the IP camera's keyframe interval is set to 60 fps for NTSC or 50 fps for PAL.
3. Test your connection
Now that you have configured your source, you can test your live stream. You'll need the[live_stream_id] returned in step 1.
- Start your live stream.
curl -X PUT \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/start" - Check the state to make sure the live stream started.
curl -X GET \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/state" - Start the stream in the RTSP encoder. How you start the encoder varies by device.
- Fetch a URL to a thumbnail that you can enter into a browser and visually confirm the stream is playing.
curl -X GET \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/thumbnail_url" - Stop the live stream.
curl -X PUT \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/live_streams/[live_stream_id]/stop" - Stop the stream in the source camera or encoder.

- GET /live_streams/[ID] — View the details of a live stream, including the player embed code and hosted page URL.
- PATCH /live_streams/[ID] — Update a live stream's configuration.
Transcoder workflow
1. Create a transcoder
In the transcoder workflow, you'll manually configure the transcoder, output renditions, and stream targets to fit your specific streaming solution.
Create a transcoder that pulls video from a RTSP source by sending a POST request to the /transcoders endpoint.
You can use the following sample request, making sure to:
- Set protocol to rtsp.
- Set source_url according to your camera type.
- For a generic camera, see your IP camera's user guide for for details about the source_url.
- For an Axis network IP camera, the source_url is in the form
rtsp://[username]:[password]@[ip_address]/axis-media/media.amp. See your Axis camera user guide or the Axis online helpdesk for details about the camera's IP address. - For a Sony SRG-300SE IP camera, the source_url is in the form
rtsp://[camera-ip-address]/video[port]. See the Sony SRG-300SE User's Guide for details about the camera's IP address.
The hostname or IP address used in the source_url must be publicly accessible. If authentication information, such as username and password, is included in the source_url, it can only contain alphanumeric, period (.), underscore (_), and hyphen (-) characters.
- Set broadcast_location to the region that's closest to your video source.
- Change any values unique to your broadcast, using the API reference documentation as a resource. See the Endpoint Reference button below.
Sample request
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ${WV_JWT}" \
-d '{
"transcoder": {
"billing_mode": "pay_as_you_go",
"broadcast_location": "us_west_california",
"delivery_method": "pull",
"name": "MyIPCameraTranscoder",
"protocol": "rtsp",
"source_url": "rtsp://camera-ip-address/videoinfo",
"transcoder_type": "transcoded"
}
}' "${WV_HOST}/api/${WV_VERSION}/transcoders"
Sample response
The response includes:
- An ID for the transcoder that you'll use throughout the rest of this task.
- source_connection_information — Because you're pulling video from the camera, you won't need to do anything futher with this information.
{
"transcoder": {
"id": "tmd8ybp2",
"name": "MyIPCameraTranscoder",
"transcoder_type": "transcoded",
"billing_mode": "pay_as_you_go",
"broadcast_location": "us_west_california",
...
"protocol": "rtsp",
"delivery_method": "pull",
"source_url": "rtsp://camera-ip-address/videoinfo",
...
"outputs": []
}
}
2. Add output renditions and stream targets
Complete the transcoder by adding output renditions and stream targets. For instructions, see one of the following articles, depending on whether you're creating an adaptive bitrate or passthrough transcoder:
Note: You'll need the transcoder ID from step 1.
- Adaptive bitrate transcoder — Create an ABR stream and send it to a target with the Wowza Video REST API
- Passthrough transcoder — Pass a stream through the transcoder to a target with the Wowza Video REST API
3. Configure your video source
You provided the source_url that gives Wowza Video with a connection to the camera when you created the live stream. Now, make sure the IP camera's keyframe interval is set to 60 fps for NTSC or 50 fps for PAL.
4. Test the connection
Now that you have configured your source, you can test your transcoder. You'll need the [transcoder_id] returned in step 1.
- Start the transcoder.
curl -X PUT \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/transcoders/[transcoder_id]/start" - Check the state to make sure the transcoder started.
curl -X GET \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/transcoders/[transcoder_id]/state" - Start the stream in the RTSP encoder. How you start the encoder varies by device.
- Fetch a URL to a thumbnail that you can enter into a browser and visually confirm the stream is playing.
curl -X GET \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/transcoders/[transcoder_id]/thumbnail_url" - Stop the transcoder.
curl -X PUT \ -H "Authorization: Bearer ${WV_JWT}" \ "${WV_HOST}/api/${WV_VERSION}/transcoders/[transcoder_id]/stop" - Stop the stream in the source camera or encoder.
