The 3D Video window is designed for 3D modeling images from the active camera.


3D Video can display:


Ground surface. The ground color is set on the tab 3D modeling in the Options Box. In multi-level 3D projects the height of the ground equals to the base height of active camera.


Grid. The presence, step and location of the grid are determined by the similar grid parameters in the graphics window.


Background. The Background is not visible by default. You can make the background visible on the View tab of the Image parameter panel or in the Main menu of 3D Video.


3D constructions; represent stretched throughout the height 2D constructions in the graphics window.


3D models. These are prepared 3D models of people, cars and other objects. See more: 3D model


3D images. Usual raster images can be placed in the 3D space. See more: 3D image


Illuminators. Illuminators Cameras are represented as 3D models.


Cameras. Cameras are represented as 3D models.

Virtual post on which the active camera is installed. Allows to see the active camera installation place projection on the ground. The post is nor displayed by default. You can make the post visible in the View tab of the Image parameter panel


Test object. Is visible in the graphical editing state of the active camera as the parallelepiped with numbers on sides.


The fragment of the test chart EIA1956 for the visual estimation of the current horizontal and vertical resolution.


Titles. At the left top corner the main image parameters are displayed.


Visibility of these objects can be switched on/off separately for each camera on the View tab on Image parameter panel. Visibility of some objects can be switched in the Main menu of the 3D Video.


Location and editing these objects are carried out in the horizontal projection of the graphics area. In the 3D Video the result of these actions can be observed.


3D Video allows to:


model different situations of the person detection and identification and license plate reading and any digital symbols in different sections of the view area, taking into account video quality parameters;


adjust person detection, identification and license plate reading criteria according to the personal demands;


disclose the view area distortions, arising from obstacles;


compare camera models, choose model with optimal parameters for the current task;


choose type, power and places of luminaries;


model resolution of megapixel cameras which exceeds screen resolution;


save obtained images in the static files or animated *.gif files;


see at the design stage that, for what the video surveillance system is made - images from video cameras.


In the 3D Video it is possible to model static and animated images considering parameters of the scene (illumination, illuminators, visibility range), cameras (sensitivity, resolution, color, exposure time, rolling shutter, interlace distortions, frame rate), lenses (focal length, F-number, resolution, distortion) and DVR (resolution, compression, brightness, contrast, sharpness). The parameters can be adjusted on the Image parameter panel and in the Sensitivity and Resolution box.


By default illumination and resolution modeling is disabled, only view area is modeled.


Mouse control in the 3D Video window


If you move the mouse cursor over the 3D Video window with the left mouse button pressed, the active camera will change direction following the cursor.

For non-fisheye cameras, if Ctrl is not pressed, the camera tilt changes by changing the view area upper bound distance. If Ctrl is pressed, the camera tilt changes by changing the height of view area upper bound.


When circular field of view of a Fisheye camera is displayed, then the camera's direction will change by changing the angles of the FishEye.


For any cameras, moving the cursor with Shift pressed will cause the camera to rotate around its axis.



Clicking with the mouse wheel directs the PiP (picture-in-picture) frame when PiP mode is enabled.


Right click opens the Image Parameter Panel.
