MJPEG, or Motion JPEG, is a video compression format that uses JPEG images for each video frame. Akuvox devices display live streams on the web interface and capture monitoring screenshots in MJPEG format. Settings related to MJPEG determine video quality and the on/off status of the live stream function. RTSP stands for Real-Time Streaming Protocol. It can be used to stream video and audio from the third-party cameras to the device. You can add a camera’s stream by adding its URL. The URL format of Akuvox devices is rtsp://Device’s IP/live/ch00_0 ## RTSP Stream Monitoring The RTSP feature allows Akuvox indoor monitors or third-party devices to obtain the live stream from the device. You can set up the RTSP authentication credentials and video parameters. ### RTSP Basic Setting You are required to set up the RTSP function on the device web **Intercom > RTSP > RTSP Basic** interface in terms of RTSP authorization, authentication, and password, etc. before you are able to use the function. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-392L7W9Q.png) **Parameter Set-up**: - **RTSP Authorization Enabled**: enable or disable the RTSP authorization. If you enable the **RTSP Authorization**, you are required to enter **RTSP Authentication Type, RTSP Username**, and **RTSP Password** on the intercom device such as an indoor monitor for authorization. - **Authentication Mode**: select RTSP authentication type between **Basic** and **Digest**. **Basic** is the default authentication type. ### RTSP OSD Setting This feature is used to add a watermark to the RTSP video or picture. To protect the owner of the video or image. To do this configuration on the web **Intercom > RTSP > RTSP OSD Setting** interface. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-NKIY8A2R.png) **Parameter Set-up**: - **RTSP OSD Color**: there are five color options - **White, Black, Red, Green**, and **Blue** for RTSP watermark text. - **RTSP OSD Text**: enter the customized text you want to show for the watermark. ### RTSP Stream Setting The RTSP stream can use either H.264 or Mjpeg as the video codec. If you choose H.264, you can also adjust the video resolution, bitrate, and other settings. Go to **Intercom > RTSP > RTSP Stream** interface. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-K34LCCXK.png) **Parameter Set-up**： - **Audio Enabled**: tick to enable RTSP audio which means, the door phone can also send audio information to the monitor by RTSP. - **Video Enabled**: the door phone can send video information to the monitor. After enabling the RTSP feature, the video RTSP is enabled by default and cannot be modified. - **2nd Video2 Enabled**: Akuvox door phones support 2 RTSP streams, you can enable the second one. - **Audio Codec**: choose a suitable audio codec for RTSP audio. - **Video/2nd Video Codec**: choose a suitable video codec for RTSP video. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-0QNUNKCQ.png) **Parameter Set-up**: - **Video Resolution**: select video resolutions among six options: **QCIF, QVGA, CIF, VGA, 4CIF**, and **720P**. The default video resolution is **4CIF**. and the video from the door phone might not be able to be shown on the indoor monitor if the resolution is set higher than **4CIF**. - **Video Framerate**: **30fps** is the video frame rate by default. - **Video Bitrate**: select video bit-rate among six options: **128 kbps, 256kbps, 512 kbps, 1024 kbps, 2048 kbps**, and **4096 kbps** according to your network environment. The default video bit rate is **2048 kpbs**. - **2nd Video Resolution**: select video resolution for the second video stream channel. While the default video solution is **VGA**. - **2nd Video Framerate**: select the video framerate for the second video stream channel. **25fps** is the video frame rate by default for the second video stream channel. - **2nd Video Bitrate**: select the video bit rate for the second video stream channel. While the second video stream channel is **512 kbps** by default. ## MJPEG Image Capturing You can take a monitoring image in Mjpeg format with the device. To do this, you need to turn on the Mjpeg function and choose the image quality. Go to **Intercom > RTSP > RTSP Basic** and **Intercom > RTSP > MJPEG Video Parameters** interface. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-S3TMYNHE.png) ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-7Q5707UF.png) **Parameter Set-up**: - **MJPEG Authorization**: tick it to access device video or real-time screenshots through a browser (http address such as: http://device IP:8080/video.cgi (dynamic video), http://device IP:8080/jpeg.cgi (static screenshot) ). - **Video Resolution**: select video resolutions among six options: **QCIF, QVGA, CIF, VGA, 4CIF**, and **720P**. The default video resolution is **4CIF**. And the video from the door phone might not be able to be shown on the indoor monitor if the resolution is set higher than **4CIF**. - **Video Framerate**: **30fps** is the video frame rate by default. - **Video Quality**: the video bit rate is from 50 to 90. ### NACK Negative Acknowledgment**（NACK）**indicates a failure or error in data transmission or processing. It is used to request retransmission or signal the failure to the sender for ensuring data integrity. To enable NACK, navigate to **Phone > Call Feature > Others**. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-QSWCSBF3.png) **Parameter Set-up**: - **NACK Enabled**: enable the NACK. It can be used to prevent losing data packets in the weak network environment when discontinued and mosaic video images occurred. ## Video Streaming You can access the real-time video from the device's camera using the Akuvox indoor monitor or other third-party devices like a Network Video Recorder(**NVR**). Enabling and setting up the video streaming function on the device will allow its video to be visible on other devices. Click [here](https://knowledge.akuvox.com/docs/integration-with-uniview-nvr-system) to view an example of using the feature: the integration with Uniview NVR System. Navigate to **Intercom > ONVIF** interface. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-IHQB9O02.png) **Parameter Set-up**: - **Discoverable**: tick the check box to enable the Discoverable mode. If you select Discoverable then the video from the door phone camera can be searched by other devices. - **User Name**: enter the user name. It is **admin** by default. - **Password**: enter the password. It is **admin** by default. After the setting is complete, you can enter the URL on the third-party device to view the video stream. For example: http://IP address:80/onvif/device_service Note: - Fill in the specific IP address of the door phone in the URL. ## Live Stream There are two ways to check the real-time video from the device. One is to go to the device web interface and view the video there. The other is to enter the correct URL on the web browser and access the video directly. Navigate to **Intercom > Live Stream** interface. ![image.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-T2PHZ2Y7.png)
