MJPEG Image Capturing

You can take a monitoring image in MJPEG format with the device. You can set up the MJPEG authorization mode and video parameters.

To set it up, navigate to Surveillance > RTSP > Basic interface.

  • MJPEG Authorization Enabled: Once enabled, accessing the door phone’s real-time image or video by entering the URL into the browser requires verification of the Authentication Mode, User Name, and Password.

Tip

  • To view a dynamic stream, use the URL http://device_IP:8080/video.cgi.

  • For capturing a screenshot, use the following URLs, with the image formats varying accordingly:

    • http://device_IP:8080/picture.cgi

    • http://device_IP:8080/picture.jpg

    • http://device_IP:8080/jpeg.cgi

For example, if you want to capture the jpg format image of the door phone with the IP address 192.168.1.104, you can enter http://192.168.1.104:8080/picture.jpg on the web browser.

You can set up the MJPEG video parameters in the MJPEG Video Parameters section.

  • Video Resolution: Specify the image resolution, varying from the lowest CIF(352×288 pixels) to the highest 1080P(1920x1080 pixels).

  • Video Frame rate(fps): Frames per second, refers to how many frames are displayed in one second of video. The default frame rate is 30fps.

  • Video Quality: The video bitrate ranges from 50 to 90.

RTSP Stream Monitoring

You can use RTSP to watch a live video stream from other intercom devices on the device.

RTSP Basic Setting

You are required to set up the RTSP function on the device web Surveillance > RTSP > Basic interface in terms of RTSP Authorization, authentication, password, etc before you can use the function.

  • RTSP Authorization Enabled: Once enabled, configure RTSP Authentication Mode, RTSP User Name, and RTSP Password. These credentials are required for accessing the door phone's RTSP stream from other intercom devices like indoor monitors.

  • Authentication Mode: It is Digest by default that uses hashing instead of the easily reversible Base64 encoding. A token is used for verification.

  • User Name: Set the username for authorization.

  • Password: Set the password for authorization.

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 Surveillance > RTSP > RTSP Stream interface.

  • Audio Enabled: Decide whether the RTSP stream has sound.

  • Video Enabled: Decide whether the RTSP stream has video. After enabling the RTSP feature, the video RTSP is enabled by default and cannot be modified.

  • 2nd Video Enabled: E12 supports two RTSP streams.

  • Audio Codecs: Choose a suitable audio codec for RTSP audio.

  • Video Codecs: Specify the video compression formats.

    • H.264: Offer highly efficient compression but at a cost of higher latency and computational load.

    • MJEPG: Offer improved quality but inefficient compression.

You can set up the video parameters for H.264 in the H.264 Video Parameters section.

  • Video Resolution: Specify the image resolution, varying from the lowest CIF(352×288 pixels) to the highest 1080P(1920x1080 pixels).

  • Video Frame rate(fps): Frames per second, refers to how many frames are displayed in one second of video. The default frame rate is 30fps.

  • Video Bitrate(Kb/Sec): The amount of video data transferred in a specific duration of time. A higher video bitrate means a higher possible quality, but also higher file sizes and more bandwidth.

  • 2nd Video Resolution: Specify the image resolution for the second video stream channel.

  • 2nd Frame rate(fps): Set the frame rate for the second video stream channel.

  • 2nd Video Bitrate(Kb/Sec): Set the bit rate for the second video stream channel. The default is 512 kbps.

RTSP OSD Setting

This feature is used to add a watermark to the RTSP video or picture.

Set it up on the web Surveillance > RTSP > RTSP OSD Setting interface.

  • RTSP OSD Color: There are five color options, White, Black, Red, Green, and Blue for RTSP watermark text.

  • RTSP OSD Text: Customize the watermark text.

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 the Intercom > Call Feature > Others interface.

  • NACK Enabled: It can be used to prevent losing data packets in the weak network environment when discontinued and mosaic video images occur.

ONVIF

You can access the real-time video from the device's camera using the Akuvox indoor monitor or other third-party devices like Network Video Recorder(NVR). Enabling and setting up the ONVIF function on the device will allow its video to be visible on other devices.

To set it up, go to the Surveillance > ONVIF interface.

  • Discoverable: When enabled, the video from the door phone camera can be searched by other devices.

  • User Name: Set the username required for accessing the door phone's video stream on other devices. It is admin by default.

  • Password: Set the password required for accessing the door phone's video stream on other devices. It is admin by default.

Tip

Once the settings are configured, to access the video stream on the third-party device, simply enter the ONVIF URL: http://Device’s IP:80/onvif/device_service.

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.

See live stream on the device Surveillance > Live Stream interface. Enter the authorization username and password set in the RTSP settings.
