Complete Construction Site Security Starts with Smart CCTV Planning!

A construction site contains valuable equipment, materials, and ongoing work that needs 24/7 protection. A properly designed CCTV system helps prevent theft, monitor worker safety, and keep every critical area under surveillance.

✅ This layout includes:
🔹 16 strategically placed CCTV cameras
🔹 Entrance & Exit monitoring with LPR cameras
🔹 PTZ cameras for heavy equipment zones
🔹 Material storage surveillance
🔹 Site office & worker area monitoring
🔹 Perimeter security coverage
🔹 Remote viewing via Mobile, Tablet & PC
🔹 24/7 recording with AI motion detection

A well-planned CCTV system not only protects your investment but also improves site safety and operational efficiency.

CCTV Storage Calculation – Quick Guide

One of the key challenges in CCTV design is estimating the right storage — not too low (risk of data loss) and not too high (extra cost).

Here’s a simple way to calculate it 👇

🔹 What affects storage?
• Number of cameras
• Resolution (2MP / 4MP / 8MP)
• Bitrate (depends on FPS & compression)
• Recording mode (continuous / motion)• Retention period (days)

🔹 Formula:Storage (TB) = Cameras × Bitrate (Mbps) × 24 × Days ÷ 8 ÷ 1024

🔹 Example:For 32 cameras, 4MP, average bitrate 4 Mbps, 30 days recording:

👉 Storage = 32 × 4 × 24 × 30 ÷ 8 ÷ 1024 ≈ 40 TB

🔹 Best Practices:
✔ Use H.265 to reduce storage consumption
✔ Adjust FPS based on project requirements
✔ Enable motion recording in low-traffic areas
✔ Always add 20–30% buffer
✔ Consider RAID for data protection

💡 Accurate calculation = optimized cost + reliable system performance
