Adding Multi-Channel Encoders

Description

In order to accommodate more than 4 channels of video, many multi-channel encoders require the use of the “bank” IP plugin override. The cameras test records should indicate this in the Notes. 

Solution

  • 1st bank channels 1-4, no override required
  • 2nd bank channels 5-8, #bank=2
  • 3rd bank channels 9-12, #bank=3
  • 4th bank channels 13-16 #bank=4

For Example, assuming the cameras IP address is 192.168.1.1:

1st bank would be:192.168.1.1
2nd bank would be:192.168.1.1#bank=2
3rd bank would be:192.168.1.1#bank=3
4th bank would be:192.168.1.1#bank=4

Override to Prevent UTC Time Zone Configuration of Samsung Cameras by the Server

Issue:

Adding a camera, disabling or re-enabling the camera, power cycling the camera, restarting the exacqVision server service, or rebooting the exacqVision Server, causes the server to set the camera’s time zone, for all cameras that allow it, to Coordinated Universal Time (also known as Universal Time Coordinated, UTC, UTC+0, UTC+00:00, “Z time”, or “Zulu Time”).  This is preferred for global video recording and playback time synchronization because UTC does not observe Daylight Savings Time (DST) changes.  This camera configuration change is therefore normal, desired, and expected behavior for video management as a whole.  However, if the expectation is that the camera’s on-screen display (OSD) must display the local time for video clip exportation in MPEG-4 (MP4) format, changing the camera’s time zone or turning off the camera’s OSD negatively impacts this use-case.

An override switch is now available for cameras that make use of the SamsungIP camera plugin (SamsungPI).

The override will prevent the server from setting the time zone on the camera to UTC+0 as would normally occur. This will only affect the camera’s internal timekeeping and its corresponding on-screen display (OSD).  The exacqVision Server’s OSD will remain unaffected and be subject to its own internal clock time zone setting.

Override commands:

To prevent the server from setting the camera’s time zone and Daylight Savings Time (DST), use:    

ipaddress#timezone=camera

Example: 192.168.1.168#timezone=camera

How to use:

For a camera to be added to the exacq Server, append the #timezone=camera override command to the Hostname/IP address field of the exacqVision Client > Add IP Cameras > IP Camera Information section.  On an already connected camera, add the override to the existing camera Hostname/IP address entry, set the camera timezone through the camera’s webpage interface, and allow the camera to reconnect.

Workaround:

Here is a DEV build engineering supplied:

https://artifactory.exacq.org/artifactory/server-local/21.12.x/32289xx/3228903/

Version Fixed:

Development build 21.12.3228903

Expected Future Release build 22.03.X

Incorrect Timestamps

Issue:

exacqVision Server may cause incorrect frame timestamps for some cameras that are using RtspPI or AxisPI plugins.

Workaround:

None

Version Affected

20.06.4 and earlier

Resolution:

A new Override is available for RtspPI and AxisPI

The Override will prevent the server from auto adjusting timestamps and will trust verbatim what comes from camera.

The server generates and caches a timestamp offset when starting a stream, which is applied to every frame as a time correction. Normally, the camera then continues to perform NTP sync operations with the server for timestamp accuracy.

However, with a busy network, some NTP packets may fail to arrive at the camera, and in some cases the camera’s time may drift beyond a 60 second threshold, which causes server to incorrectly adjust and freeze its cached offset, which will be applied to every frame regardless whether the camera successfully NTP syncs with server.

Most noticeable in multi-sensor cameras and encoders.

The new override is #timestamp=trusted

Version Fixed:

exacqVision Server 20.09.8

IP Plugin Overrides

The standard form for exacqVision camera addresses is as follows:

{host}{?parameter_1=value_1}…{?parameter_n=value_n}{#override_1=value_1}…{#override_n=value_n}

  • The host is required and must be in the format of an IPv4 address or FQDN (dot separated domain location).
  • The 1 or more name=value parameters are separated by ? and are optional. These are passed to the device.
  • The 1 or more name=value overrides are separated by # marks and are optional, but always last. These are passed to the plugin to modify plugin behavior.

Override Definitions

OverrideDescription
transportStream session with the specified protocol { TCP | UDP }.
timestampStamp frames with server or camera time.
timezone{ UTC | camera | server } Determine if camera timezone is set to UTC+0, left as camera or set to that of server.
zoomOverride configuration or operation zoom function.
blocksizeOn by default, but could turn off blocksize in the RTSP session for some cameras with streaming issues.
profileConnect to profile number N; N is a number from 1 to the number of profiles supported by the camera.
natSupport NAT translation to WAN address.
bankSelect 4 channel encoder banks. N is 1 – number of banks, usually in set { 1 | 2 | 3 | 4}.
supportOverride support API. For example, used by Vivotek to support either legacy or oneFw.
streamSelect a specific stream ID for devices supporting multiple streams.
