Security Camera System Calculator
Estimate the number of cameras, total camera cost, and monthly storage (TB) needed to cover a perimeter from coverage distance and bitrate.
How to Use the Security Camera System Calculator
- Enter the perimeter length in metres.
- Enter each camera's coverage distance.
- Enter the bitrate per camera in Mbps.
- Enter the price per camera.
- Click Calculate.
Casi d'Uso
- •Warehouse / facility perimeter planning.
- •Retail CCTV quotes.
- •Residential estate security design.
Formula
Cameras = ⌈perimeter / coverage⌉. Storage TB/month = cameras × bitrate × 86 400 × 30 / 8 / 1 000 000.
Domande Frequenti
Is 24/7 recording assumed?
Yes — the formula uses 86 400 seconds/day. For motion-activated recording, multiply by an activity factor (typical 0.2–0.4).
What bitrate is typical?
1080p H.264 ≈ 4 Mbps, 4 K H.265 ≈ 8–16 Mbps. Check your camera datasheet for accurate numbers.
Does this cover the NVR and cabling?
No — it sizes the cameras and raw storage. Add NVR, PoE switches, and cable runs into your project budget separately.
