MJPEG and RTSP are the primary monitoring stream types discussed in this chapter.
MJPEG, or Motion JPEG, is a video compression format that uses JPEG images for each video frame. Akuvox door phones 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 door phone. You can add a camera’s stream by adding its URL.
ONVIF is Open Network Video Interface Forum. It enables the door phone to scan and discover cameras or intercom devices with activated ONVIF functions. Live streams obtained through ONVIF are essentially in RTSP format.
MJPEG Image Capturing
You can take a monitoring image in Mjpeg format with the door phone. To do this, you need to turn on the Mjpeg function and choose the image quality.
Navigate to Intercom > RTSP > MJPEG interface.
Parameter Set-up:
- Image Quality: select the quality for the image capturing among seven options: QCIF, QVGA, CIF, VGA, 4CIF, 720P, 1080P.
After the Mjpeg service is enabled, you can capture the image from the door phone using the following three types of URL format:
- 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.
Live Stream
There are two ways to check the real-time video from the door phone. 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 the device web Intercom > Live Stream interface.
RTSP Stream Monitoring
You can use RTSP to watch a live video stream from other intercom devices on the door phone.
RTSP Basic Setting
You are required to set up RTSP function on device web Intercom > RTSP > RTSP Basic interface in terms of RTSP Authorization, authentication, and password, etc., before you are able to use the function.
Parameter Set-up:
RTSP Authorization: enable or disable the RTSP authorization. If you enable the RTSP Authorization, you are required to enter RTSP Authentication Type, RTSP Username, 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.
User Name: enter the name used for RTSP authorization.
Password: enter the password for RTSP 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.
Navigate to Intercom > RTSP > RTSP stream interface.
Parameter Set-up:
Video Codec: select between two types of codec options: H.264 and Mjpeg according to your need.
Video Resolution: select video resolutions among seven options: QCIF, QVGA, CIF, VGA, 4CIF, 720P, 1080P. The default video resolution is 720P. 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 720P.
Video Framerate: 25fps is the video frame rate by default.
Video Bitrate: select video bit-rate among six options: 128 kbps, 256kbps, 512kbps, 1024kbps, 2048 kbps, 4096kbps according to your network environment. The default video bit-rate is 2048 kbps.
2nd Video Resolution: select video resolution for the second video stream channel. The default video solution is VGA.
2nd Framerate: 25fps is the video frame rate by default for the second video stream channel.
2nd Video Bitrate: select video bit-rate among the six options for the second video stream channel. The second video stream channel is 512 kbps by default.
Dynamic Coding: if it is enabled, the dynamic coding will be automatically adopted for the video preview and monitoring on the SmartPlus App. The video resolution will be optimized when you use your SmartPlus app for the call preview for the incoming call from the door phone and for the door phone monitoring.
Note:
- R29 series supports two video stream channels for H.264 codec video stream.
ONVIF
You can access the real-time video from the door phone 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 door phone will allow its video to be visible on other devices.
Navigate to Intercom > ONVIF >Basic Setting interface.
Parameter Set-up:
Discoverable: Discoverable mode enables the video from the door phone camera to be searched by other devices. It is enabled by default.
User Name: enter the user name. The user name is admin by default.
Password: enter the password. The password is admin by default.
After the setting is complete, you can enter the ONVIF 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.
Door Phone Camera Exposure Adjustment
Door phone camera exposure can be turned on the web Intercom > Camera > Camera Control interface in order that indoor monitors or third party devices can obtain the video with improved quality.
Parameter Set-up:
- Exposure Mode: turn on the camera exposure mode if needed.
