First project with VideoCAD, step by step
|
||
Problem
Let's suppose you have a layout in any of the formats: * .bmp, * .png, * .jpg, * .gif, * .tif, * .emf, * .wmf, * .dxf, * .dwg, * .pdf.
On the layout there are points of interest, which must be monitored.
It is necessary to choose the optimal placement and parameters of cameras.
Solution
If this is your first project with VideoCAD, the order of solving the problem may consist of the following steps:
Brief introduction to the interface
Navigation on the layout is convenient using a mouse with a wheel. You can move the layout by the mouse with pressed wheel, scale the layout by turning the wheel.
Press Ctrl to reduce scaling step.
The sequence: Press right mouse button> Move the mouse> Release the right button forms a black magnification frame.
If it is inconvenient to use the wheel mouse, see the buttons on the Toolbar: Move Zoom in and Zoom out
The initial mode from which all actions begin is called Select / Edit mode. You can switch to the initial mode by clicking the button on the left part of bottom row of the Toolbar or by pressing Esc on the keyboard.
VideoCAD employs a context-sensitive help system. This means that the program tries to direct you to the portion of the help system that is most likely to answer your question, based on what you are viewing or doing. To get detailed information about any component, box or menu item, move the input focus (mouse cursor) to the component and press F1. To get detailed information about any button on the Toolbar, right click on it then choose What's this? pop-up item..
For more information see. Graphics window, Graphics area, Current construction parameter panel, Selection editing panel, Status bar
|
1. Choose Main menu, Drawing>Load background> In Horizontal projection.
2. In the appeared dialog, select the file of your layout and click Open button. The layout will appear in the Graphics area.
You can quickly turn a screen image from any graphics program, Google, OSM, Yandex maps into a background:
1. Expand the program window with the terrain map on the screen. To display a full screen map from the Internet browser, press F11 on the keyboard. 2. Press Print Screen (or Alt + Print Screen) on the keyboard. 3. Open VideoCAD and select Menu> Drawing>Paste background from clipboard. 4. Click Crop background on the Adjust background box to cut out only the desired portion of the map. Next, scale the background in the usual way.
This handy method of importing maps is suitable for any program, allows to get background of several monitors size and does not depend on third-party services.

Drawing constructions
Around the places of interest that should be monitored, right on the layout, outline the elements of buildings with the help of constructions. The construction buttons are located in the middle of the bottom row of the Toolbar. Outline the walls, columns, and slabs using the Wall and Rectangle tools. Drawing a construction is performed by two clicks on the layout.
To draw walls that will require cutting openings or inserting windows or doors, use only the Wall tool. Set the thickness and switch the orientation of the wall while drawing it. .
To undo / redo the last action, use the buttons on the right side of the bottom row of the Toolbar or Ctrl + Z, Ctrl + Y. To construct cylindrical surfaces, use the Circle and Arc. To draw stairs use Stairs. To construct vertical rectangular planes and to measure distances, use the Line. To measure angles, use Angle. For drawing in 3D plates or any other raster images, use 3D image. To construct inclined, transparent and complex surfaces, use Inclined rectangle.
Theoretically, by a set of Inclined rectangles you can draw anything, although it may not be easy.
To create oblique objects you can turn vertical constructions into a 3D model. 3D models can be tilted and transformed.
Use the Polygon tool to draw complex flat objects.
More complex objects can be modeled in SketchUP and imported in VideoCAD.
Editing constructions
|
To see your constructions in 3D, open the 3D World window by the button in the right part of top row of the Toolbar.
In the 3D World window, you can navigate in 3D space with a wheel mouse.
If you are lost in the 3D World, click on the button in the upper left corner of the 3D World window or open the Tool panel of the 3D World window by clicking on the button in the upper left corner of the window, click the buttons on the Navi tab of the 3D World window.
To make view in the 3D World stable while adding new constructions - place any 4 constructions on the corners of your "construction site" - mark its borders.
For monitoring your constructions in 3D, you can also open the 3D Video window by the button on the right part of top row of the Toolbar and direct the camera located on the layout at your constructions. Camera control will be discussed below.

It is recommended to avoid overload of the project with details that have no influence on the design decisions. For beautiful images you will be able to add details during the final design of the project. For comfortable work with complex plans, it is recommended to move unnecessary details to separate layers, which you can turn on and off. See more: Program speed and system requirements

Open the 3D Video window by the button in the right part of top row of the Toolbar.
If you move the mouse cursor over the 3D Video window with the left mouse button pressed, the camera will change direction following the cursor. If you hold down Shift while moving, the camera will rotate around its axis. When Ctrl is pressed, the camera tilt will be changed by changing the View are upper bound height.
|
|
Open the Pixel density box by the button in the center of top row of the Toolbar.
If you move the mouse cursor over the images, then the expanded image under the cursor will appear at the top of the box. Clicking on the image opens The Table of Images.
By comparing the colors on the colored view area on the layout and in the table, you can estimate pixel density of the camera at each point on the layout. From the pictures in the table, you can estimate with what resolution a person and a license plate can be displayed and what part of the frame they can occupy.
|
Select position and parameters of a camera
You can select cameras as well as constructions: using the selection frame or by clicking. Use the Move and Rotate buttons or the pop-up menu to move and rotate the selected cameras. You can find these buttons on the left of bottom row of the Toolbar.
Current value of the Lens focal length can be seen and changed in the Lens focal length combobox in the middle of top row of the Toolbar and in the Camera Geometry box.
By moving and rotating the camera on the layout, choose the optimal installation location. If the camera can be installed at different heights, select the camera installation height in the Camera Geometry box.
If you can change the lens, choose the lens focal length by moving the grips at the corners of the view area or by selecting values in the comboboxes.
If you can change model of the camera, select the resolution in pixels in the Camera Geometry box.
Thus, the choice of position and parameters of a camera is a task with large number of variables. VideoCAD is designed to help in solving such problems.
Note that a fragment of the area of interest, bounded by a yellow frame, is shown in a green frame with the real camera resolution. This is how the PiP tool works (picture in picture). To enable PiP, enable the Image processing, clear the item in the Main Menu of the 3D Video window, Speed> Disable image processing. Specify a place for the yellow frame by clicking by the middle mouse button (wheel) on the image. To change options of the PiP mode, right-click on the image and switch to the PiP tab of the appeared Image parameter panel.

Active camera
Place and adjust new cameras on the layout as well as the first camera.
|
View of the view area projection and shadows from obstacles
The group of buttons on the left side of top row of the Toolbar controls the view of the view area projection of the active camera on the layout and in 3D. There are a lot of combinations of these buttons with the drop-down menus. You can read about them later and try how they work. At the first stage of learning, leave these buttons in default positions.
If there are selected cameras, then these buttons are colored by crimson and control all the selected cameras at once.
The Shadow button controls calculation of shading the view area from surrounding objects.
To enable shadow calculation, select Within projection in the drop-down menu of the button. To turn off shadows for the active camera, select Off.
Automatic calculation of shadows is carried out only for the active camera. For other cameras, shadows are displayed from memory. If you need to recalculate shadows for a particular camera - activate it. To recalculate shadows for all selected cameras, click Main menu> View> Recalculate shadows.
In the case of a large number of shading objects, the calculation of shadows becomes a complex resource-intensive operation. It is not recommended to keep the shadow calculation turned on permanently.
To disable the automatic calculation of shadows (with keeping the already calculated shadows), uncheck the item Main menu> View> Calculate shadows for active camera.
While calculating shadows, the red frame flashes on the Shadows button.

Instead of entering camera parameters one by one from the specification, you can select a camera model from the Table of camera models. You can open the Table of camera models using the button in the center of the top row of the Toolbar.
There are 2 tabs in the Table of camera models window:
To select a previously unused camera model, switch to the All Models tab. The tab selector is located in the upper left corner of the Table of camera model window.
The set of visible parameters in the table is flexibly configured. Try to select predefined parameter sets in the list in the Views panel at the bottom of the table.
You can control visibility of individual columns using the menu in the upper left corner of the Table.
To show the model parameters compactly, in the form of a card, click on the button Camera model card.
The database of camera models is regularly updated with new models. You can download camera model database updates from cctvcad.com to the local model database on your computer using the Download (camera model database on cctvcad.com) on the toolbar of the All Models tab of the Table of Camera Models or using the Camera model databases on cctvcad.com Main menu of the Graphics window.
To assign parameters of a model to the active camera select by clicking a row with the desired model and click on the button in the lower left corner of the window.
You can also assign a model to the active camera without the Table of camera models, by selecting the model name in the Model of active camera combobox in the center of the top row of the Graphics window Toolbar. By default, only the models used in the project are listed in the combobox. To display all models choose SHOW ALL MODELS in the list.
To filter camera models by combination of many criteria open the Camera model filter box.
You can add your own camera models to the Camera model database.
You can order special Camera model database add-on file, including parameters of user-defined models, entered according to their specifications.

VideoCAD offers tools that simplify and speed up work with complex projects, as well as allow you to solve problems that go beyond simple examples.
3D Test and 3D Test on view area bounds
3D Test allows you to quickly evaluate how any 3D model from the VideoCAD library can look at any point in space through an active camera.
You can select any 3D model from the library or directly on the layout, click on its location and evaluate how it will look. On the Current construction parameters panel, you can change sizes of the 3D model and its height above the ground. You can rotate and scale the test model with the mouse in the 3D Test window to examine it closely.
See more: 3D Test
Line types
Instead of setting parameters for each construction separately, you can choose pre-configured line types for constructions, cameras, 3D models and cables. Each line type contains information about the style, thickness, color of the line separately in 2D, 3D and in printing, the preset heights for the constructions and 3D models, whether the line type is a cable and whether this line type should be considered an obstacle when calculating shadows.
See more: Line types
Fonts
For text labels, titles and captions there are customizable fonts. The font parameters include: name, style, color, size, mark whether the font is scalable.
See more: Fonts
Snaps
During drawing, the mouse cursor "sticks" to points, lines, and directions. The snap settings can be quickly changed during working in the Snap panel, which can be opened by the Global snap button in the right part of the bottom row of the Toolbar.
See more: Snaps
Vertical projection of the layout
When necessary, you can open the vertical projection of the layout using the Hide vertical projection button in the right part of the top row of the Toolbar. In the vertical projection, you can also place constructions, 3D models and cables. To move the horizontal projection relative to the vertical projection - move the mouse with the middle button (wheel) pressed and holding the Ctrl key.
To study the vertical projection of the active camera's view area, there is the Graphical editing state of the active camera. .

All text resources (headers, messages, headings of tables and lines in reports..) are stored in text files with * .lng extension and can be customized.
Layouts
There can be up to 10 layouts in a project. Layouts can correspond to a separated parts of an object of video surveillance. In the PDF report, you can print plan drawings separately.
See more: Layouts
Layers
Constructions, cameras and 3D models can be distributed by layers. You can control activity, visibility, color, height and other parameters of each layer. When exporting a drawing, the layers are exported into layers of AutoCAD * .dxf and * .dwg file formats.
See more: Layers
Camera Groups
Cameras can be combined into groups. You can control the activity, visibility, color and other parameters of groups. In the PDF report, you can print group drawings separately.
See more: Camera Groups
Camera Positions
Cameras may contain "snapshots" of their parameters and positions - positions. You can copy positions to cameras and copy cameras to positions. Positions can be displayed in 2D and 3D as well as cameras. Positions allow you to model multisensor cameras, PTZ camera presets and Fisheye cameras. But their use is not limited to this.
See more: Camera Positions
Numerate cameras tool
There is a special tool for renaming cameras on layouts with sequential numbering.
See more: Numerate cameras
Selection filter
The tool allows you to quickly filter selected objects and cameras by many criteria and their combinations: type of construction or 3D models, camera models, lens focal lengths and camera resolutions, layers, line types, color in 2D and 3D, materials.
You can filter only objects that get fully or partially within the specified range of heights.

Calculation of person detection, person identification and license plate reading areas
Estimation of possibility of person detection, person identification and reading a license plate only by the pixel density (pixel density) is convenient, but inaccurate. The license plate or face of a person can simply not get into the view area in height, or get at too big angle and the task of identification or reading license plate will not be solved. At the same time, to detect a person it is not necessary to get the whole person in the frame, it is enough to see a part of his body. Possible height range of appearance of a License plate does not equal the height range of appearance of a person’s face.
Therefore, the real area of person identification will be less than the colored region on the view area projection, the real area of license plate reading will be shifted relative to the colored region, and the real area of person detection will be more than on the projection.
To eliminate this error VideoCAD offers more rigorous tools, taking into account the height restriction and limiting angles. You can read about them by the links below.
You can use these tools when you need a more accurate result.

Physically accurate modeling of camera functionality
VideoCAD offers unique tools for physically accurate modeling internal functionality of video cameras.
Effective use of such modeling tools requires sufficient understanding of camera operation. Some of parameters required for accurate modeling are missing in the manufacturers specifications or their values in the specifications are overrated or ambiguous. Therefore, these parameters have to be obtained or verified experimentally.
In the current practice of CCTV designing such modeling is not mandatory. However, these tools allow to increase accuracy of the projects, to model cases that can not be modeled in other design programs. These tools allow qualified designers to effectively apply and demonstrate their skills, convincingly justify their decisions, create projects and business proposals that are superior to competitors' products.
Modeling tools are described in detail in the help system:
