Page History

Creation and configuration of the Video camera object is done in the Hardware tab. The object tree of a video camera is generated automatically according to its functions which are integrated into the Axxon Next software package (the presence of alarm inputs, relay outputs, PTZ unit, etc.). 

...

When you have added a camera via the IP Device Discovery Wizard (see Adding and removing IP devices),   you can edit the camera's parameters. The camera parameters are grouped as follows.

...

...

1. The IP address (assigned automatically and can be changed if necessary).

   Info
   title Note
   The port used to transmit data between the camera and the Axxon Next VMS (this value is set to 80 by default but can be changed if necessary).

   
   

2. At first the port number is set through the camera's Web interface.

3. Camera positioning coordinates (latitude, longitude, azimuth).

4. The MAC address.
5. Manufacturer, model, firmware.
6. The number of the video channel (for an IP Server).

7. Device serial number (for Axis devices only, see Axis IP Devices).

...

1. If you want to interrupt video streaming from the camera to the Server whenever it is not needed, select Yes for Break unused connections (211).
   Conditional interruption of video transmission from a camera to the Server, if:
   1. the video stream is not displayed on either Client or web client layout.
   2. the stream is currently not being recorded into Video Footage.
   3. the stream is currently not being processed by any detection tool.
2. After starting the Client, the default setting is to display video only after the first I-frame (key frame) is received. If the stream comes with a relatively long GOP length (Group of Pictures) or GOV length (Group of Video Object Planes),   e. the number of P- and B-frames between I-frames in the stream, the video may be not available for a minute. In this case, select Yes for the Low GOP keyframe rate setting (2). This will reduce the waiting time for video by pushing the preceding I-frame that can be stored in the memory buffer on the Server.   In some cases, the I-frame will not be buffered, but in most cases this means that it will soon be received from the device.

...

This value should be between 50 and 1000 milliseconds. If the value 0 is selected, video buffering is disabled.

In the Camera settings  group group you can see video image parameters (contrast, brightness, color saturation, etc.). When configuring these, you can look up short parameters' descriptions in Axxon Next GUI. For more detailed information, please refer to the camera manual.

...

...

To configure video streams, you should make sure that the Send settings to device checkbox is selected.An adaptive video stream can be configured if necessary (see Configuring an Adaptive Video Stream).

...

You can alter video stream settings by sending an HTTP request to the device (see its manufacturer's documentation) through some macros (see Executing a web Web-query, Starting an external program on Servers, Starting an external program on Clients).

...

If a camera does not support multistreaming, the parameters of the video streams are identical. In this case only the parameters of the high-quality video stream are editable (the parameters of the low-quality video stream are adjusted automatically).

Image from the camera will be displayed in the preview window.

...

To switch between streams in the preview window, click the High-quality stream and  and Low-quality stream tabs.
