Designing CCTV Systems: working with a site plan and finding optimal camera positions


Welcome to the part 3: Site Plan, Floor plans and optimal camera locations. On the tab called Site Plan we can load a background image, like a site map or a floor plan and place a few cameras to find good camera positions, and see camera coverage and camera zones to choose optimal camera resolutions and lenses. Now we can load a background image. We right click the Toolbar button Box, then click Load Background menu item to choose a file to load. The program can load background images from BMP, JPEG, PNG and PDF files. The professional version can also load AutoCAD DWG or DXF files in vector format When the file is chosen the program asks to
scale the background image. For scaling we need to specify 2 points of the background image with a known distance in meters or feet between them. After clicking these 2 points the program shows a window where we can enter the distance. For example 6 meters. Now the background image is scaled and all distances on this plan are the same as in the real world. For your convenience you can lock the background from accidental modification by opening a popup menu using a Right mouse click and choosing the Lock In Place menu command To scroll the plan you can press and hold the mouse wheel while moving the mouse. Also you can use your keyboard by pressing ALT key and arrow keys You can rotate the mouse wheel to Zoom in and Zoom out of the site plan. To add a camera in any place of the site plan please press the right mouse button and choose Add Camera from the popup menu. You can move the camera into an initial camera location and see the camera zones. To make it look realistic we can add obstacles, like walls, fences, trees, and cars To add a wall please right click the Wall button in the Toolbar and choose a type of the wall from the menu. It could be a brick wall, a thick brick wall, curved wall or painted wall. Then you need to specify the starting point and the ending point of the wall. To change wall height you can modify H parameter in the toolbar. To change the elevation of the wall above the floor you can modify L parameter. To make it look more realistic we can add windows, doors, transport and furniture. You can copy and paste objects here using Ctrl+C and Ctrl+V keyboard shortcuts. … You can press SHIFT key to draw straing walls. You can type objects width from the keyboard and press ENTER. To delete you can press Del (Delete) button. To undo you can press CTRL+Z By positioning all of these objects and looking at your site plan you can decide where to locate and how to position your cameras. And important point when talking about cameras and doors is that if you need to identify people who are coming through this door, but your area near the door is not Red, meaning it is not a part of the Identification zone then you have 3 ways to fix it 1. Make the camera location closer to the door 2. Choose a camera with higher resolution 3. Make the Field of View narrower Thank you for watching
