Stream On Demand

Some settings have been introduced on the recorder related to a camera's stream. Through the Stream audio/video option on the camera configuration screen you can determine whether a camera's stream is always streaming to the device manager or whether you want to reduce network traffic and only stream video when you need it. Similarly, you have the option to stop the stream as well.

This feature is commonly used in interview or interrogation rooms or anytime a meeting needs to be completely private. Not streaming video from a camera can also reduce network traffic and is especially useful in LTE environments. This feature applies to all streams from the camera. When a stream is stopped, video is not recorded nor available live to any client user. Audio is also not recorded or transmitted.

There are three options for the Stream audio/video field:

Streaming - Always

When the Stream audio/video drop-down is set to 'Always', the default value, live video streams from the camera to its assigned device manager. If Standard Recording is set to 'Yes' and the recording period is set to 'Always', the camera streams 24/7/365 and cannot be turned off manually. If configured, video is recorded to its corresponding zone(s) and sent to any authorized client (Ocularis Client, Ocularis 5 Web or Oculari 5 Mobile) seeking to view it.

Streaming - On Demand - Quick Stream Start

When the option On Demand - Quick Stream Start is selected, video streams from the camera to its device manager but is then discarded. In Ocularis Client, a view pane with this camera appears empty with the message 'Camera connection lost' when a view with the camera is displayed. If an operator wants to view video from that camera, he/she must manually request it from a client by alarm scenario or executing a manual event (such as a trigger). Once the stream is enabled, it can be recorded (if configured to do so) or displayed to any client requesting it. The stream remains active until disabled via another event (either manual or automated).

Video flows from the camera to the DM and is discarded.

If an operator wants to view live video he or she can request it via manual trigger from Ocularis Client, Ocularis Web or Ocularis Mobile. (providing that a camera level trigger has been configured in advance).

Streaming - On Demand

When the option On Demand is selected, video does not stream from the camera to its device manager. A view pane with this camera appears empty with the message 'Camera connection lost' when a view with the camera is displayed. If an operator wants to view video from that camera, he/she must manually request it from a client by alarm scenario or executing a manual event (such as a trigger). Once the stream is enabled, it can be recorded (if configured to do so) or displayed to any client requesting it. The stream remains active until disabled via another event (either manual or automated). Since the video when using the 'On Demand' option does not stream from the camera to the device manager by default, network traffic is reduced. This feature is also useful if transmitting camera video via wireless over broadband.
