Edgerecording

There are two modes how EDGE video footage is grabbed from the camera.

  • In real time: Which means that it is streamed in normal speed to the DVR. This has the advantage that it does not add much load to the network, but has the disadvantage that it is quite slow
  • As fast as Possible: Which means that video is downloaded with maximum network bandwith available. This bears the advantage, that the edge video footage is grabbed in a short time, but could lead to network issues if you have a heavy loaded network

Also you can specify for how much time the edge video is overlapping with your normal video. So if your gap in the stream is for example 60 seconds long and you specify five seconds for overlapping, the edge part downloads 70 seconds in total. 60 seconds for the gap, and 5 seconds before and after the gap.

Edge recording in the E4 Plugin uses the ONVIF Protocol. For more information about ONVIF Edge recording see Edge Recording.

IR function

To find out what IR capabilities the camera has, click Get IR information.

The selection of an entry has two effects:

  • When you select a setting, it is immediately sent to the camera and activated in the camera.
  • By selecting auto, lightsensor or smart you select the setting used for sending the CameraDayNightMode (Auto) action. If you want to use one of these three auto modes, you must select it here.

Explanation of the different modes

Manualoff

manualon

auto

These modes do not activate the camera's IR LEDs if there are any. So if you have a camera with built-in IR LEDs, the IR LEDs will always remain off in these modes. In most cases, these modes are not a good choice for cameras with IR LEDs. However, you can use it if you do not use the camera's IR LEDs and want to use external IR illumination.

lightoff

lighton

smart

lightsensor

Lightoff and Lighton are similar to Manualoff and Manualon, but this time the IR-LED is also switched on.

Smart and Lightsensor are both automatic modes that select between Lightoff and Lighton depending on the ambient light.

Smart will make the decision based on the incidence of light on the camera's sensor. This is the best mode in predominantly bright environments.

Some cameras have an external light sensor on the device. If you select a light sensor, it will be used for the decision.

Absolute PTZ

PTZ cameras enable absolute and relative positioning. Positioning is possible with MoveToAbsolutePosition and MoveToRelativePosition.

This is always possible regardless of whether the Absolute PTZ option is activated.

It is also possible that the G-Core server communicates the position of the camera via the action CameraAbsolutePosition. For this function Enable Absolute PTZ must be activated.

If this function is activated, there will be a periodic action in the system. This time span can be set with Periodical prompt.

The G-Core Server also reports the position after each movement to a preset position and stops a movement. How quickly the action is triggered after the stop can be set via Delay after move.

Explanation of Parameters for Actions

This action will be fired by a user to move the camera to a desired position.

Explanation of action parameters

PTZ Head

Media channel number of the camera.

alpha

This is a pan value in degree. Allowed range is -180 to 180.

beta

This is a tilt value in degree. Allowed range is -10 to +190.

zoom

This is a zoom value in total. Allowed range is 0 – 9999.

Depends as well on zoom capabilities of camera.

focus

This is a focus value in total. Allowed range is 0 – 9999.

Depends as well on zoom capabilities of camera.

alpha speed and beta speed

Not used in the E4 plugin.

This action will be fired by the G-Core server to notify the user about the current position of the camera.

Explanation of action parameters

PTZ Head

Media channel number of the camera

updated

True if G-Core has received valid information from camera.

False if G-Core has not received valid information from the camera. If false, the last valid values are transferred.

alpha

This is a pan value in degree. Allowed range is -180 to 180.

beta

This is a tilt value in degree. Allowed range is -10 to +190.

zoom

This is a zoom value in total. Allowed range is 0 – 9999. Depends as well on the zoom capabilities of the camera.

focus

This is a focus value in total. Allowed range is 0 – 9999. Depends as well on the zoom capabilities of the camera.

This action will move the camera from the current position for desired degree.
