Viewing live and playback video using Workbench

The driver supports streaming live video and the playing back of recorded video.
Prerequisites: You are using Workbench.
For video streaming, the Maxpro Web Services API supports HPS (Honeywell Progressive Streaming). Unlike the streaming provided by other Niagara video drivers, HPS does not provide a continuous video stream. Instead, it continuously repeats a two–step streaming process. Before beginning the process, the Maxpro Video Driver skips the first media file (with index 0), as suggested by Maxpro Web Services team, and renders video only from media file 1. The protocol asks for the next available media file number, then it renders a one- or two-second chunk of video from the file. It repeats these two steps to stream video. This process takes a few seconds to start rendering video in the Live and Playback views.

After reading and rendering data from a single media file, HPS reads the next file from the Maxpro NVR. The short delay (a few milli-seconds) displays a still frame between reading and rendering each file.

Perform the following steps:
  1. Navigate to the camera and double-click it.
    The view defaults to live video.
  2. Select a video recording to play back and click the Play Back button.
    The recorded video plays back.
  3. To pause, rewind or fast forward the recorded video, click a button.
    Fast forward and rewind take a few seconds to stop the existing video stream, start a new stream, and set the direction and speed. This causes a delay. It happens every time you click a forward or rewind control to change the change the playback speed. This limitation is expected.

    Rewind flows smoothly. Forward exhibits a jumpy flow. This is due to the generation of media files from the Maxpro NVR software.

  4. To change pan, tilt and zoom, click Preset, select a preset from the drop-down list and click OK.
    The Maxpro Web Services API does not provide an API to read the list of presets from the Maxpro NVR. By default the Maxpro Video Driver provides the option to choose the presets from 1-255 using a drop-down list.
