rtsp://[USERNAME]:[PASSWORD]@[IP]:554/video.mp4

rtsp://[USERNAME]:[PASSWORD]@[IP]:554//video.pro1
URL Path Description
/video.mp4 MP4 main stream (most common format)
//video.pro1 Profile 1 / primary stream (double-slash prefix)

Alternative URL Formats

Some Zavio models support these alternative URLs:

URL Pattern Notes
rtsp://IP:554/video.mp4 MP4 stream (recommended for most models)
rtsp://IP//video.pro1 Profile 1, primary stream
rtsp://IP:554//video.pro2 Profile 2, sub stream
rtsp://IP//video.h264 Direct H.264 stream (B5110 and similar)

Connecting with VisioForge SDK

Use your Zavio camera's RTSP URL with any of the three SDK approaches shown in the Quick Start Guide:

// Zavio B7110, MP4 main stream
var uri = new Uri("rtsp://192.168.1.90:554/video.mp4");
var username = "admin";
var password = "admin";

For profile-based cameras, use //video.pro1 for the primary stream or //video.pro2 for the sub stream.

Snapshot and MJPEG URLs

Type URL Pattern Notes
Profile Snapshot http://IP/cgi-bin/view/image?pro_CHANNEL Snapshot by profile number
JPEG Snapshot http://IP/jpg/image.jpg Standard JPEG snapshot
Sized JPEG http://IP/jpg/image.jpg?size=3 JPEG with size parameter
CGI JPEG http://IP/cgi-bin/jpg/image CGI-based JPEG snapshot
MJPEG Stream http://IP/video.mjpg Continuous MJPEG stream
MJPEG (quality/FPS) http://IP/video.mjpg?q=30&fps=33&id=0.5 MJPEG with quality and FPS control
Profile HTTP Stream http://IP/stream?uri=video.proN Profile-based HTTP stream

Troubleshooting

"401 Unauthorized" error

Zavio cameras ship with default credentials of admin / admin. If the camera has been configured with different credentials:

  1. Access the camera at http://CAMERA_IP in a browser
  2. Log in and check Network > RTSP settings
  3. Verify that RTSP authentication is enabled and your credentials are correct

Choosing between /video.mp4 and /video.proN

Zavio cameras have two URL families. The correct choice depends on your model:

  • Most models (B7110, F210A, F312A, F520IE, F521E, F731E, etc.): Use /video.mp4
  • Older or profile-based models (B5110, B5210, D3100): Use //video.pro1
  • If one format fails, try the other

Double-slash in profile URLs

Profile-based Zavio URLs require a double-slash (//) before video.proN. This is intentional:

  • Correct: rtsp://IP//video.pro1
  • Incorrect: rtsp://IP/video.pro1

If you omit the double-slash on a profile-based model, the connection may fail.

No video with MPEG-4 codec

Some older Zavio models default to MPEG-4 encoding. If you experience codec issues:

  • Log in to the camera web interface
  • Change the video codec to H.264 under the stream configuration
  • Use the /video.mp4 or //video.pro1 URL after changing the setting

Port 554 connection refused

Verify that RTSP is enabled on the camera:

  • Web interface: Check Network > RTSP settings
  • Confirm port 554 is not blocked by a firewall
  • Default RTSP port is 554

FAQ

What is the default RTSP URL for Zavio cameras?

The most common URL is rtsp://admin:admin@CAMERA_IP:554/video.mp4 for the MP4 main stream. For profile-based models, use rtsp://admin:admin@CAMERA_IP//video.pro1 instead.

Do Zavio cameras support ONVIF?

Yes. Most Zavio models support ONVIF, which provides a standardized method for camera discovery and streaming without needing brand-specific URL patterns.

What is the difference between /video.mp4 and /video.pro1?

/video.mp4 is a direct stream path used by most newer Zavio models. //video.pro1 and //video.pro2 are profile-based paths that reference stream profiles configured in the camera's web interface. Profile 1 is typically the main (high-resolution) stream, and Profile 2 is typically the sub (lower-resolution) stream.

What are the default login credentials for Zavio cameras?

The default username is admin and the default password is admin. It is strongly recommended to change these credentials after initial setup.

Can I control MJPEG quality and frame rate?

Yes. Zavio cameras support MJPEG parameters in the URL. Use http://IP/video.mjpg?q=30&fps=33&id=0.5 to specify quality (q), frames per second (fps), and stream identifier (id).
