In Short
Planning Figures Before You Speak to a Contractor
These planning calculators help estimate CCTV storage requirements, camera coverage, and indicative project budgets before engaging a contractor. They are designed to provide realistic Singapore-based planning figures for budgeting, proposal evaluation, and early-stage system design: not as substitutes for a site survey, but as tools that help property owners, facility managers, and MCST councils arrive at that conversation better prepared.
All four calculators are free, require no registration, and produce instant results. The figures are based on Singapore market rates and typical deployment assumptions. A site survey produces the accurate numbers for a specific property: but these tools provide the planning range that makes that conversation significantly more productive.
Available Calculators
These tools answer the most common questions that arise before a security installation: how much storage will my cameras need, how many cameras does my site require, and what will this system roughly cost. All figures are Singapore-calibrated and update instantly as you adjust inputs.
Which Calculator Should I Use?
I need to size a CCTV system
Start with the Camera Coverage Calculator to determine how many cameras are needed, then use the Storage Calculator to size the NVR and hard drives for your retention requirement.
I need a budget figure
Use the CCTV Cost Calculator for camera systems and the Access Control Cost Calculator for door access. Both produce a budget range suitable for board papers and AGM proposals.
I have received a proposal and want to sense-check it
Run the CCTV Cost Calculator or Access Control Cost Calculator with the same inputs as the proposal. A result significantly outside the calculator range: in either direction: warrants clarification from the contractor.
I am designing M&E drawings or specifications
Use the Storage Calculator to determine NVR room and rack space requirements, and the Coverage Calculator to validate camera positions and identify gaps before drawings are finalised.
CCTV Bandwidth & Storage Calculator
How much NVR storage do you need, and how long will your recordings last? Configure each camera by resolution, frame rate, compression codec, and motion activity level. The calculator totals the bandwidth and storage across your entire system: and tells you how long a given hard drive capacity will last at those settings.
Camera Coverage Calculator
How many cameras does your site need, and what resolution is right for each position? Enter your site dimensions and camera specifications to see detection, recognition, and identification coverage zones using the DORI standard: the same methodology security engineers use to specify cameras professionally.
CCTV System Cost Calculator
Get a budgetary estimate for a CCTV system before requesting proposals. Configure camera count, camera type (standard IP, full-colour night vision, PTZ), NVR specification, and installation complexity. Figures reflect Singapore market rates for supply, installation, and programming: useful for budget approval or board papers before a site survey.
Door Access Control Cost Calculator
Estimate the full cost of a door access control system: not just hardware. Configure number of doors, credential type (card and PIN, face recognition, or video intercom), whether time attendance is required, and installation complexity. Covers supply, installation, programming, and first-year support for Singapore commercial and institutional properties.
These are indicative estimates, not quotations. Actual costs and requirements vary based on site conditions, cable run distances, building structure, existing infrastructure, and specific product selection. A site survey by a Securevision engineer gives you the accurate figures: and it is free and without obligation. Use these calculators to prepare a budget range and understand scale before that conversation.
Before You Request Proposals
The most useful time to run these calculators is before you speak to any contractor: so you arrive at that conversation with a realistic sense of scale, storage requirements, and budget range. That makes the site survey more productive and helps you evaluate proposals with context.
Budget Planning
Use the cost calculators to prepare a capital expenditure request or board paper with a realistic budget range before committing to a site survey process. The figures are indicative but sufficient for budget approval in most Singapore organisations.
Design & Specification
Use the storage and coverage calculators during building design to determine NVR room space requirements, network switch specifications, and cable infrastructure sizing: before M&E drawings are finalised.
Proposal Evaluation
Run the cost calculators after receiving proposals to sense-check whether the figures are within a reasonable range for Singapore market rates. A proposal significantly outside the calculator range: in either direction: warrants clarification.
Frequently Asked Questions
Questions we hear before and after visitors use the calculators.
Are the calculators free to use?
Yes. All four calculators are completely free, require no login, and store no personal information. Results are generated instantly in your browser. There is no obligation to contact Securevision after using them.
How accurate are the estimates?
The calculators provide indicative planning figures based on Singapore market rates and typical deployment assumptions: not quoted prices. Actual costs and requirements vary based on site conditions, cable run distances, building structure, existing infrastructure, and specific product selection. They are accurate enough for budget planning, board paper preparation, and proposal sense-checking. A site survey provides the accurate figures for a specific property.
Can I use these figures for AGM proposals or board papers?
Yes: this is one of the primary use cases the calculators are designed for. The cost calculators produce a budget range sufficient for capital expenditure requests, MCST AGM proposals, and board papers in most Singapore organisations. We recommend presenting the figures as indicative estimates based on an online planning tool and noting that a site survey will provide the confirmed specification and cost.
Why are actual quotations different from the calculator results?
Calculator figures are based on typical Singapore deployment assumptions. Actual quotations reflect the specific conditions of a property: cable run distances through complex building structures, existing infrastructure that can be reused or must be replaced, specific product selections, and operational requirements that only become clear during a site survey. The calculator range should overlap with a well-specified quotation for a typical installation. Significant differences: in either direction: are worth asking about.
Are the calculations based on Singapore market rates?
Yes. All cost calculators use Singapore market rates for supply, installation, and programming based on Securevision's active project experience. Storage and coverage calculators use Singapore deployment assumptions: tropical climate considerations for outdoor equipment, typical Singapore building layouts, and standard installation practices used by licensed security contractors in Singapore.
Do I need a site survey after using the calculator?
Yes, if you are proceeding to installation. The calculators provide planning-stage estimates. A site survey by a Securevision engineer gives you the accurate camera positions, cable routing, infrastructure requirements, and confirmed system cost for your specific property. The site survey is free and carries no obligation. The calculators help you arrive at that conversation with realistic expectations about scale and budget.
Can Securevision review my calculator results?
Yes. If you have run the calculators and would like a Securevision engineer to review your inputs and discuss whether the assumptions are appropriate for your property, book a site assessment or send us a WhatsApp message. We can advise on whether your planned camera count, storage specification, or budget range is realistic for your specific property type and operational requirements.
