CCTV Camera Coverage & Count Calculator
A first-pass plan for a home or building CCTV system — how many cameras, the NVR size, storage for your retention period, and an indicative cost. Estimates for planning, not a quotation. Runs in your browser.
- Cameras (6)₹24,000
- NVR (8-ch)₹6,400
- Storage (8 TB)₹7,200
- Cabling & install₹9,000
Planning estimate only — actual counts depend on lens choice, mounting heights and sightlines, and prices vary by brand and installer. Position cameras to cover entries and the boundary, keep footage secured and retained per any local rules, and never place cameras in private spaces (bathrooms, changing areas).
