CCTV Design & Modelling Software

26th November 2021 11:32 am Leave a Comment

SGW are pleased to announce the implementation of CCTV Design & Modelling Software into the Consulting Practice.

SGW has invested in professional CCTV system design software and training for our CCTV & Security Design Consultants to use the software competently, for the benefit of future projects.

SGW now utilises the power of VideoCAD Professional 3D, one of the most powerful 3D & visualisation CCTV Design platforms available. By utilising professional 3D modelling software, SGW can model the proposed CCTV solution before our client commits to a system purchase, this allows SGW to provide our clients with accurate detailed CCTV design documentation, covering scene parameters, camera parameters, volumetric camera coverage, light levels & associated performance, based on the lighting levels, camera blind spot data, image depth-of-field, camera type, camera performance within the installed environment, day /night imagine performance, moving objects and many more parameters.

SGW strives to use design and modelling software, in conjunction with a matching test procedure, using the BS EN 62676 compliant Video Image Calculator (VIC) target to provide an end-to-end service, from concept design to image quality validation. After all, as IEC 62676-4 Section 5.2 states, “Without an OR [operational requirement] and a matching test procedure there is no practical methodology to assess whether the system can meet its required purpose.”

SGW’s adoption of the powerful software allows not only a full 3D rendered view of site layouts but also provides visual monitoring layouts to accurately emulate the images the operators will see from the camera in multiple lighting and weather conditions.

VideoCAD is a drafting and calculating tool that helps SGW’s consulting team define camera positions and angles of coverage when designing a CCTV system of any size. Without this software, client Operational Requirements for a CCTV system are more difficult to address properly and accurately due to many variables one can find in defining camera locations, angles of view, CCD chip sizes, object distances, recognition of faces or vehicle license plates. The software helps skilled and experienced design engineers to select the correct lenses, number of cameras and positions.

Software Interface – Camera Location Parameters

Using this software, SGW’s design service can:

Determine the most suitable lenses, heights, and locations for camera installation to provide viewing areas with the possibility to detect and identify a person and read license plates.
Choose the best camera location for the desired outcome using the graphics window with a CAD interface.
Calculate the horizontal projection sizes of viewing, person detecting, identifying and license plate reading areas to draw them on the object plan.
Measure distortions of the viewing area arising from natural obstacles.
Calculate the image size of any object on a CCTV display (as seen by a camera), in the percentage of the display size, in pixels, TV lines and millimeters.

The software generates a drawing containing two projections of objects layout with their respective camera images. Also, the viewing areas are calculated, indicating cable distances, showing grid coordinates and text to be pasted into explanatory notes as an illustration as well.

Commenting on SGW’s Adoption of 3D modelling software for Video Surveillance Systems (CCTV) Design, Simon Whitehouse, Managing Director at SGW said: The use of 3D modelling in Video Surveillance Systems Design, allows our team to visually simulate the levels of coverage, the field of view, likely blind spots, and potential performance during the development of Level 2 Operational Requirements. It’s often a challenge to suitably communicate where possible blind spots would occur if surveillance camera placement was to proceed in particular configurations without a suitable software simulation, so I’m convinced that our design software will help support the client to make an informed decision associated with approval and budget allocation aligned with an agreed Level 2 Operational Requirement and conceptual system design.

SGW launches Security Courses Online

SGW Safety and Security Ltd is an independent security consulting practice providing unbiased expertise for security projects internationally, across a broad range of sectors, industries and environments.

Planning Today – Protecting Tomorrow, SGW aligns itself closely within the built environment, helping its clients to develop safe, secure and sustainable landmark projects.

Underpinned by experiences gained over the years within its consulting operations, delivered by higher degree qualified consultants and chartered professionals, SGW has built a credible reputation in providing specialist Counterterrorism. Risk management and Security Design training programmes for individuals who aspire to become practising security professionals.

Aims & Objectives of Security Courses Online

Security Courses Online will eventually provide a portfolio of externally accredited courses that are focused on the provision of professional security-related training programmes, which aim to meet the needs of the building and construction industry, facilities and asset management sectors.

The first in the series of Security Courses Online will be SGW’s Security Surveying & Assessment Course, which provides occupational standards & competencies for individuals working in the Built Environment.

This programme is based upon security surveying and assessment which follows a risk-based approach, for both proposed and in-use built infrastructure assets. The course programme will examine the different techniques used by security professionals to undertake a security assessment of a new site at the pre-construction stage by evaluating architectural drawings and visualisations or an in-use site, with a physical site survey visit and stakeholder consultation.

Security Needs Assessment

The Security Needs Assessment module includes a review of competencies, techniques, tools and resources necessary to undertake a visual audit of the site and surroundings, identifying environmental cues and features pertinent to the security of the proposed development or in-use facility. This includes determination of plot extents, spatial use, infrastructure placement, access, circulation and the application of CPTED principles.

Facility Security Risks

The Facility Security Risks module will review the components and techniques used to undertake a ‘high level’ quantitative and qualitative Security Risk Assessment. Based upon the context of a sample project, delegates will identify critical assets, vulnerable points and design based threats of both an in-use and pre-construction facility, using assessment data provided within the course workbook and also, within the public domain.

Facility Security Review

The Facility Security Review module will review and identify conclusions made in the Facility Security Risks module and techniques which can be applied by the security professional, to guide project stakeholders to make informed decisions on risk mitigation measures to be adopted and the production of the Level 1 Operational Requirement (OR1) to ensure that the solution is acceptable to all and that they have ownership of it.

Course Syllabus

This course will be spread over a one month period and will comprise of one-two hours live webinar each week, presented by SGW’s course tutors and security professionals. Following the conclusion of each weekly webinar, delegates will progress through a module-based workbook and prepare a final short assignment, for a final group presentation.
