Problem

 

There is a layout with the placed cameras. We need to determine the required cable length separately for each brand of cable.

 

Order of work

 

       1. Configure a separate line type for each brand of cables used in the project

 

1.1 Open the Options box, switch to Lines tab.

1.2 In the Number box, select any unused number of line type.

 

Do not select line types, used as system lines.

 

1.3 In the Name box, type a name of a cable brand, which will correspond to the selected line type.

1.4 Check the Cable box. Clear the Shadow box.

1.5 When necessary, adjust the line Style, Color and Width on the screen and at printing.

1.6 To make lines of this type invisible on the 3D Video, set equal the maximum and minimum heights on the 3D panel.

1.7 Repeat  steps 1.2  .. 1.6 for all brands of cables used.

1.8 Click OK in the Options box.

 

       2. Assign brands to cables of cameras

 

2.1 Activate any of cameras.

 

2.2 Assign brand to the signal cable

2.2.1 Click the menu item Main menu>Cables>Signal cable>Calculate.

2.2.2 In the appeared Signal cable length calculation box choose Cable brand from the adjusted at p.1 line types.

2.2.3 When necessary, adjust reserve for cable laying and connection.

2.2.4 Click OK in the Signal cable length calculation box.

 

2.3 Assign brand to the power cable

2.3.1 Click the menu item Main menu>Cables>Power cable>Calculate.

2.3.2 In the appeared Power cable electrical parameters and length calculation box choose Cable brand from the adjusted at p.1 line types.

2.3.3 When necessary, adjust reserve for cable laying and connection. Specify electrical parameters.

2.3.4 Click OK in the Power cable electrical parameters and length calculation box.

 

2.4 Repeat  steps 2.1  .. 2.3 for all cameras, cables of which must be taken into account.

 

You can control a correct cable parameters of cameras in the Table of cameras.

 

       3. Draw cables of cameras in horizontal and vertical projection

 

3.1 Activate any of cameras.

3.2 Choose Main menu>Signal cable and draw the signal cable of this camera.

3.3 Choose Main menu>Power cable  and draw the power cable of this camera. .

 

When this item chosen, you can draw the signal cable of the active camera by successive clicks in the graphics area. The end of each segment is the start of the next one. To stop drawing cable, press ESC.

 

The status bar displays the segment length and its projection to distance and height.

 

Both clicks are to be made in the same projection. If the projections are different the measured values are incorrect, therefore when constructing a segment with its ends in different projections the values are not displayed in the status bar. In this case when changing the drawing the segment is attached to the projection with its initial point.

 

A cable consists of segments, allowing to draw it in different projections and layouts, representing an actual scheme of laying accurately.

 

When copying the cable segments between cameras and layouts a process of cable drawing is accelerated considerably even in complex CCTV systems.

 

When drawing a cable the menu item Cable laying might be used. When choosing it a float panel of the same name appears enabling to choose a shift of segment ends for a level parallel cable drawing along the walls, columns etc.

 

If  the Main menu>View>All cameras' cables item is checked, cables of all cameras will be visible, but only cables of the active camera can be edited. If this item is not checked, cables of the active camera will be visible only.

 

       4. Draw the Main cables (which is not associated with cameras)

 

4.1 Draw the Main cables with the help of tools Line segment and   Polyline , using the adjusted at p.1 line types.

 

Line type can be assigned before drawing lines or during editing lines on the Line type panel. To change Line type of several selected lines at once, use the Change line type tool.

 

       5. Get the Cable report

 

Choose Main menu>Cables>Cable report. The Cable report includes lengths of the cables attached to cameras and the main cables as well. Cable lengths is calculated for each brand (line type) separately.
