While designing security systems for sites, deciding on the number, type and position of surveillance cameras have always been a complex process involving time-consuming calculations. Now, this has become much as easier with new tools that can integrate with 3D visualization applications.
While designing security systems for sites, deciding on the number, type and position of surveillance cameras have always been a complex process involving time-consuming calculations. Now, this has become much as easier with new tools that can integrate with 3D visualization applications.
Axis Communications, for instance, offers a range of free tools that integrate with major computer-aided design (CAD) software used in architectural planning, building layout and system design.
“Tools like these help designers decide on the ideal position for each camera by simulating camera coverage based on the camera's field of view and required resolution,” said Göran Sandberg of Axis Communications in a report.
How it works

To use the tools available from Axis, systems designers can import existing layouts to the CAD software or draw up new layouts and then simply drag and drop cameras into the drawing plans. The software will help designers understand how the set-up will look in real life, how the cameras integrate with the surroundings and the areas that the surveillance system will cover once installed.
“Once placed in the design, the software shows the camera's entire field of view as a colored area, with a resolution guide that helps determine the area where the target image solution is met,” Sandberg said.
The designers or systems integrators can try out different camera models, positions and viewing-angles to decide on the best possible installation plan. The software allows the users to control focal length, target resolution and mounting height.
In some of the CAD software, there is also an option for users to see the security camera’s point of view. Some even offer options to make adjustments to the camera while in this view, allowing users to understand the overall effectiveness of the installation beforehand.
“Once all cameras have been placed in the building design, it is then easy to verify the coverage area for the entire video surveillance solution,” Sandberg said. “These images/scenes can also be used talking to the end user in regards to the systems’ functionality, and help out setting the correct expectations which can then be achieved by the system once installed.”
Benefits for SIs
The most obvious benefit of 3D visualization is help with deciding camera positions and placement. Planning with the CAD software can reduce the chances of mistakes and ensure efficient design.
The process can also help systems designers to decide on the camera requirements for various situations. Hence, the users can not just decide on the right camera placement but also its image quality.
More significantly from a business perspective, 3D visualization will help systems integrators provide the best service to their customers by helping them understand what to expect.
“By demonstrating exactly what the installed system will look like, what it will cover and what camera views to expect, clients will be able to understand the capabilities and limits of the system,” Sandberg said. “The installation and approval process can be streamlined and the list of issues that will need to be fixed before a project can be signed off can be significantly reduced.”
