Open the H.264 RTP Server Settings dialog to configure the camera's H.264 support.
This parameter controls operating mode of the RTP server. There are three types of operating modes:
| Operating Mode | Description |
|---|---|
| Off | The RTP server with H.264 video encoding is not running. |
| On | The RTP server with H.264 video encoding is running permanently. Video encoding is permanently active in this mode and can be used at any time without delay. |
| Auto | The RTP server is running permanently, but H.264 video encoding is only activated if needed. The server automatically switches between regular operation and H.264 encoding when clients are requesting and.264 video stream. |
Caution: If H.264 video encoding has been activated, certain limitations in the camera functionality apply.
Use this parameter to switch between RTP Unicast and RTP Multicast. Multicast mode is only available if the RTP server is running permanently.
IP address of the network interface that is used to send the multicast data. Use this IP address for the rtsp request in your player software. The default is the factory IP address of the camera.
IP address of the multicast group, to which the video data are being sent. This address must be within the SSM (Source-Specific Multicast) range (232.0.1.0 to 232.255.255.255). If you leave this field empty, the server automatically chooses a valid IP address. The automatic address selection should work fine for most scenarios.
In multicast mode, the video stream is accessed using the same rtsp URL as in Unicast mode. The server automatically sends the multicast IP and the port to the recipients.
In multicast mode, the server uses up to four consecutive ports to send the audio and video data to the recipients. Enter the first port four this range in this field. The port has to be in the range of 1025 and 65632. The default value is 18888.
Make sure that this port range is not blocked by the recipient's firewall.
The TTL ("Time To Live") specifies how many hops (routers) the multicast packets can pass before being discarded. The valid value range is 1 to 255. The default value (1) means that the multicast packets are only distributed within the current subnet of the camera.
This section allows using different presets for image resolution and image quality.
In scenes that show a lot of movement, the CPU load increases due to H.264 encoding. Note that you should reduce either the frame rate or the image quality in such a scene.
The following table shows an overview of the available presets.
| Preset | Image Size | Frame Rate (frames per second) | Encoding Quality, Frame Rate | Priority |
|---|---|---|---|---|
| VGA (fast) | 640x480 | 20 | Good, variable | Frame rate |
| VGA (quality) | 640x480 | 10 | High, constant | Image quality |
| XGA (fast) | 1024x768 | 12 | Good, variable | Frame rate |
| XGA (quality) | 1024x768 | 6 | High, constant | Image quality |
| HD (fast) | 1280x720 | 8 | Good, variable | Frame rate |
| HD (quality) | 1280x720 | 4 | High, constant | Image quality |
| Mega (fast) | 1280x960 | 8 | Good, variable | Frame rate |
| Mega (quality) | 1280x960 | 2 | High, constant | Image quality |
| Full HD (fast) | 1920x1080 | 4 | Good, variable | Frame rate |
| Full HD (quality) | 1920x1080 | 1 | High, constant | Image quality |
On system with dual image sensors, this parameter selects the image sensor that is to be used for H.264 encoding.
Use this parameter to rotate the image by 180 degrees. Note that rotating the image will reduce the frame rate, especially when encoding images with higher resolutions.
Use this parameter to include audio in the H.264 video stream. Note that this option is only available if a corresponding audio input has been configured and activated in the Microphone and Speaker dialog.
While H.264 encoding is running, most of the camera functions concerned with image generation are switched off:
In addition, the following limitations apply for the H.264 video stream:
To play back the H.264 video stream, open the following URL in a suitable player:
rtsp://192.168.178.27:554/mobotix.h264
Examples for suitable players:
As an alternative, you can also play back the H.264 video stream in a browser. Note that this requires an installed plugin, such as the "Apple QuickTime Plugin".
When using VLC for playing back the H.264 video stream, problems may appear if the frame rate is below 4 fps. You can avoid these problems by adjusting the setting for network buffering in the VLC configuration.
To do so, open Tools > Settings in the VLC menu and proceed as shown below:
1000 ms. Higher values improve the playback stability, but also increase the delay between recording and playback. Use the following values, depending on the frame rate:
2000 ms.3000 ms.Klicken Sie auf Setzen, um die Einstellungen zu aktivieren und bis zum nächsten Neustart der Kamera zu sichern.
Klicken Sie auf Voreinstellung, um diesen Dialog auf die werkseitigen Voreinstellungen zurückzusetzen (dieser Button wird nicht in allen Dialogen angezeigt).
Klicken Sie auf Wiederherstellen, um alle Änderungen seit dem letzten permanenten Speichern der Konfiguration zu verwerfen.
Beenden Sie den Dialog durch Klick auf Schließen. Hierbei wird geprüft, ob Änderungen der Gesamtkonfiguration vorliegen. Ist dies der Fall, werden Sie gefragt, ob die Gesamtkonfiguration dauerhaft gesichert werden soll.
