CCTV Multi NVR Designer

Enterprise CCTV Multi-NVR System Designer

Designing large-scale CCTV systems requires more than basic camera and storage calculations. The Enterprise Multi-NVR System Designer allows system architects, consultants, and commercial installers to model multi-recorder deployments, access switch topology, core backbone load, RAID storage performance, and N+1 redundancy planning — all in one place.

Use this tool to engineer stable, scalable CCTV infrastructure for warehouses, schools, hospitals, shopping centres, and large commercial sites.

Enterprise CCTV Architecture Planning Tool

Modern enterprise CCTV deployments often exceed 64, 128, or even 256 cameras. At this scale, incorrect planning can result in:

• NVR throughput saturation
• Core switch congestion
• Uplink bottlenecks
• Storage shortfalls
• RAID misconfiguration
• Insufficient redundancy
• Expansion limitations

This system designer helps prevent those issues before equipment is purchased or installed.

What This Tool Calculates

1️⃣ Multi-NVR Load Balancing

The tool calculates:

• Total system bitrate
• Required number of NVRs
• Balanced camera distribution per NVR
• Bitrate load per recorder
• NVR headroom percentage

This ensures recorders operate within safe performance limits rather than at maximum rated throughput.

2️⃣ N+1 Redundancy Modelling

Enterprise environments often require failover capability.

When N+1 redundancy is enabled, the system automatically:

• Adds an additional standby NVR
• Redistributes camera load
• Models failover capacity

This helps determine whether the system can tolerate a recorder failure without losing recording coverage.

3️⃣ Access Layer & Uplink Planning

Large CCTV systems require structured network design.

The planner calculates:

• Required access switches
• Cameras per switch
• Uplink traffic per switch
• Core aggregation load

Warnings are generated if:

• Uplink bandwidth approaches saturation
• 10G backbone is recommended
• Core switching capacity may be insufficient

This helps prevent future congestion and performance degradation.

4️⃣ RAID & Storage Architecture Modelling

For enterprise NVRs with multiple drive bays, the tool models:

• Usable storage based on RAID type
• RAID 1, RAID 5, RAID 6 overhead
• Effective TB per recorder
• Estimated retention days
• Retention target validation

This ensures storage design meets compliance, corporate, or insurance retention requirements.

5️⃣ Enterprise Retention Validation

The planner compares:

• Calculated retention
• Target retention

If storage configuration does not meet the required number of days, it will flag the issue.

This prevents under-sizing storage in large deployments.

6️⃣ Visual Topology Graph

The integrated topology chart visualises:

• Per-NVR load
• Per-switch load
• Core network load

This provides a high-level architectural overview suitable for:

• Client presentations
• Internal engineering review
• Pre-deployment validation

Ideal Use Cases

This tool is ideal for:

• Warehouses and distribution centres
• Schools and universities
• Hospitals and healthcare facilities
• Shopping centres and retail precincts
• Industrial and manufacturing sites
• Multi-building commercial campuses

Engineering Best Practices

For stable enterprise CCTV infrastructure:

• Keep NVR utilisation below 80–85%
• Maintain uplink headroom above 20%
• Use 10G backbone for systems exceeding 1Gb aggregate load
• Implement N+1 redundancy for critical environments
• Validate RAID storage meets retention targets

Designed for Professional Installers & Consultants

Unlike basic camera calculators, this tool considers:

• Throughput engineering
• Layered network topology
• Redundancy strategy
• RAID storage architecture
• Future expansion capacity

It is built to support professional-grade CCTV system design.
