Bandwidth Calculator - Network Bandwidth for IP Cameras Free

How to Use the Bandwidth Calculator

1. Enter number of cameras on your network (from 1 to 100+)
2. Select resolution — 2MP (1080p) through 12MP (4K)
3. Choose frame rate — 5fps for low-motion areas, 15-30fps for standard surveillance
4. Select compression — H.264, H.265, or H.265+ and see the bandwidth difference instantly
5. Get total bandwidth in Mbps and recommended connection speed

Perfect for network engineers, CCTV installers, and IT professionals designing IP surveillance networks.

Features

• Per-camera bitrate — bandwidth estimate for each individual camera
• Total system bandwidth — aggregate for all cameras combined
• Network recommendations — 100Mbps vs 1000Mbps suitability
• Compression comparison — see savings with H.265 vs H.264
• Multiple resolutions — 2MP (1080p) through 12MP (4K)

Use Cases

• Office security upgrade — calculate if your existing network switch can handle 16 new 4MP cameras
• Retail store design — plan bandwidth for 8 cameras recording 24/7 in a small boutique
• Warehouse deployment — determine if you need a 1000Mbps backbone for 32 high-resolution cameras
• Remote site monitoring — check if your internet uplink can support remote viewing of all cameras
• System expansion — see how adding 4 more cameras affects your total network load

FAQ

How much bandwidth does a single 4K camera use?

A 4K (8MP) camera at 15fps with H.265 compression typically uses 8-16 Mbps. With H.264, that number jumps to 15-25 Mbps per camera.

What’s the bandwidth difference between H.264 and H.265?

H.265 (HEVC) typically reduces bandwidth by 30-50% compared to H.264 at the same resolution and quality. H.265+ can save even more, up to 70% in static scenes.

Can I run 32 cameras on a 100Mbps switch?

It depends on resolution and compression. 32 cameras at 2MP with H.265 would use roughly 96-128 Mbps, which exceeds a 100Mbps switch. You’d need a gigabit switch or reduce quality settings.

Does frame rate affect bandwidth less than resolution?

Not necessarily. Dropping from 30fps to 15fps roughly halves the bandwidth. Dropping from 4K to 1080p reduces bandwidth by about 75%. Both are significant factors.

Tips

• Use H.265+ / Smart Codec when available — it dynamically adjusts encoding for massive savings in static scenes
• Separate camera traffic from your main office network using VLANs to avoid congestion
• Always leave 20-30% headroom on your network switch for burst traffic and future expansion
