Low-Voltage & Electronic Security CAD Drafting
Electronic security and low-voltage projects need drawings from someone who knows how these systems go into a building.
1CADSource provides CAD drafting and system documentation for electronic access control, video surveillance, intrusion detection and integrated electronic security projects, working with security contractors, access control integrators, low-voltage system contractors and related commercial building systems providers.
Our experience includes systems for commercial, institutional, healthcare, government and other security-sensitive facilities, so we can work from your project information in the language your team already uses.
Low-voltage systems we draft
Our drafting experience covers:
- Electronic access control systems
- Intrusion detection and security alarm systems
- CCTV and video surveillance systems
- Integrated electronic security and related low-voltage systems
Whether a project involves one system or several working together, we keep the documentation organized around your scope.
Drawing preparation and project support
We produce system documentation for your estimators, project managers, designers and field teams. Deliverables are defined with your team and depend on your source information and project scope. They may include:
- System plans prepared on architectural or existing building backgrounds
- System diagrams prepared from your design information
- Drawing revisions as field conditions and project requirements change
- Cleanup and updates of existing CAD files
- Project-specific system documentation
This gives your team added drafting capacity during busy periods, with a clear package defined before production starts.
Revisions as projects develop
Low-voltage work often changes as a project develops. Device locations move, backgrounds get updated and the field finds conditions the original plan didn’t show. We bring those changes into one organized set and carry each one through the sheets in the agreed scope.
When information is unclear or conflicts with another document, we’ll return a specific question to your team. Once the answer is confirmed, we’ll update the drawings and reissue the affected sheets as agreed.
What to send
A strong starting package usually includes:
- Current DWG or PDF drawings and building backgrounds
- Your system information, layout plans and field notes
- Equipment information your team has selected
- Project requirements you want reflected in the drawings
- Your CAD standards, symbols, title block and sheet format
- The sheet list, project stage and target date
If only PDFs or scans are available, we can scope a redraw, subject to source quality and project scope.
Handling security-sensitive drawings
Security system drawings can reveal how a facility is protected, so please hold them until we’ve agreed how project files will be shared. An initial inquiry only needs a general description of the project, the systems involved, the approximate sheet count and your target date. If your client has specific document-handling requirements, tell us during scoping.
Contractor direction and scope boundaries
Your team directs the system and reviews the drawings before they’re issued. We take responsibility for accurate, organized CAD production of the agreed package, and system engineering and field work stay with your company, as the FAQs below explain.
How this differs from our fire alarm service
Low-voltage and electronic security drafting is a separate specialty from life-safety work. For fire alarm shop drawings and revisions, see our fire alarm CAD drafting service. If your project also involves consulting-engineering design documents, our MEP CAD drafting service may also apply.
Frequently asked questions
Do you design or engineer security systems?
No. We provide CAD drafting and documentation. System engineering, equipment selection and design decisions stay with your company and its qualified professionals.
Do you install, program or commission systems?
No. 1CADSource is a drafting provider. We don’t install, program, test, commission or certify low-voltage or security systems.
Can you use our symbols and templates?
Yes. Send your CAD standards, symbol library, title block and sheet templates with the project information, and we’ll follow them.
Can you update drawings that someone else created?
Yes. We can revise existing DWG files. If only PDFs or scans are available, we can review them and scope a redraw.
How is a project priced?
Pricing depends on the scope. Well-defined packages can often be quoted as a fixed fee, while evolving work may suit hourly billing. We’ll confirm the approach before production starts.
Have a low-voltage project ready for drafting?
Send a general project description, the systems involved, the approximate sheet count and your target date. We’ll follow up to define the scope and arrange how to share project files.
