How to Design a Professional CCTV Network Topology for a Multi-Floor Building (300 IP Cameras)
A Complete Enterprise Guide Using Cisco Catalyst C9300X-24Y, Hikvision IP Cameras, Fiber Optic Backbone, and NVRs
Introduction
Designing a CCTV system for a multi-floor building requires more than simply installing cameras. A professional surveillance network must provide:
- High availability
- Easy maintenance
- Fast video transmission
- Centralized monitoring
- Future expansion
- Organized cable management
In this tutorial, we'll design a network for a 9-floor building with 300 Hikvision IP cameras, using Cisco enterprise networking equipment and a fiber optic backbone.
Project Overview
| Equipment | Quantity |
|---|---|
| Hikvision IP Cameras | 300 |
| Floors | 9 |
| Cameras per Floor | 30 |
| 48-Port PoE Access Switch | 9 |
| Cable Manager | 9 |
| Optical Distribution Frame (ODF) | 10 |
| Cisco Catalyst C9300X-24Y Core Switch | 1 |
| 24-Port Gigabit Monitoring Switch | 1 |
| Hikvision NVR (64 Channel) | 4 |
| Hikvision NVR (32 Channel) | 1 |
| LCD/Video Wall | 5–9 Displays |
| UPS | 2 |
| Network Rack | 6 |
Network Design Overview
9 Floors
30 Cameras │ CAT6 │ Cable Manager │ 48-Port PoE Switch │ SFP Module │ Fiber │ ODF │ ========================== IT ROOM ========================== Main Fiber ODF │ Cisco Catalyst C9300X-24Y │ 24-Port Gigabit Switch │ CAT6 Patch Cables │ 5 Hikvision NVRs │ HDMI │ LCD / Video Wall
Step 1 – Floor-Level Network Design
Each floor follows the same layout.
30 Hikvision Cameras │ CAT6 Cable │ Cable Manager │ 48-Port PoE Switch │ SFP Module │ Fiber Patch Cord │ Floor ODF │ Fiber Backbone
Why use a Cable Manager?
A cable manager keeps Ethernet cables organized by:
- Preventing cable damage
- Improving airflow inside the rack
- Making maintenance easier
- Providing a professional installation
Step 2 – Access Switch Design
Each floor contains:
- 48-Port PoE Switch
- Cable Manager
- Fiber ODF
Recommended port allocation:
| Port | Device |
|---|---|
| 1–30 | IP Cameras |
| 31–40 | Future Expansion |
| 41–44 | Access Points / IoT Devices |
| 45–46 | Maintenance |
| 47–48 | SFP Uplink (depending on switch model) |
This leaves spare ports for future growth without replacing the switch.
Step 3 – Fiber Backbone
Instead of connecting every floor with copper cable, use fiber.
Floor Switch │ SFP Module │ Single Mode Fiber │ ODF │ Main ODF
Benefits
- Long-distance communication
- High bandwidth
- Electrical isolation
- Easier upgrades
- Reliable inter-floor connectivity
Step 4 – IT Room Design
The IT Room is the heart of the surveillance network.
Recommended rack layout:
Rack 1 Fiber ODF ↓ Cable Manager ↓ Cisco Catalyst C9300X-24Y ↓ Cable Manager ↓ 24-Port Gigabit Switch ↓ Patch Panel
Step 5 – Cisco Core Switch
The Cisco Catalyst C9300X-24Y aggregates all fiber uplinks from the building.
Functions include:
- VLAN management
- Layer 3 routing
- High-speed switching
- Inter-floor communication
- NVR connectivity
- Monitoring network
Recommended VLANs:
| VLAN | Purpose |
|---|---|
| 101 | Floor 1 Cameras |
| 102 | Floor 2 Cameras |
| 103 | Floor 3 Cameras |
| 104 | Floor 4 Cameras |
| 105 | Floor 5 Cameras |
| 106 | Floor 6 Cameras |
| 107 | Floor 7 Cameras |
| 108 | Floor 8 Cameras |
| 109 | Floor 9 Cameras |
| 200 | NVR Network |
| 300 | Management Network |
Step 6 – Monitoring Network
The Core Switch connects to a dedicated Gigabit switch.
Cisco Core Switch │ CAT6 Patch Cable │ 24-Port Gigabit Switch
The monitoring switch provides network connections for:
- NVRs
- Operator PCs
- Video Wall Controller
- Network Printer
- Management Workstation
Step 7 – NVR Layout
Recommended allocation:
| NVR | Camera Count |
|---|---|
| NVR-1 (64 Ch) | 60 |
| NVR-2 (64 Ch) | 60 |
| NVR-3 (64 Ch) | 60 |
| NVR-4 (64 Ch) | 60 |
| NVR-5 (32 Ch) | 30 |
Each NVR connects to the monitoring switch using a CAT6 patch cable.
Step 8 – Video Wall Design
NVR1 ─┐ NVR2 ─┼────► LCD 1 NVR3 ─┼────► LCD 2 NVR4 ─┼────► LCD 3 NVR5 ─┘────► LCD 4 │ Operator PC
You can also use a video wall controller if multiple displays need to show combined layouts.
Step 9 – IP Address Plan
| Device | Example IP |
|---|---|
| Core Switch | 192.168.1.1 |
| Monitoring Switch | 192.168.1.2 |
| NVR-1 | 192.168.200.10 |
| NVR-2 | 192.168.200.11 |
| NVR-3 | 192.168.200.12 |
| NVR-4 | 192.168.200.13 |
| NVR-5 | 192.168.200.14 |
Floor 1 cameras:
192.168.101.10 – 192.168.101.39
Floor 2 cameras:
192.168.102.10 – 192.168.102.39
Continue the same pattern for the remaining floors.
Step 10 – Rack Layout
Rack 1
- Main Fiber ODF
- Cable Manager
- Cisco Catalyst C9300X-24Y
- Monitoring Switch
Rack 2
- NVR-1
- NVR-2
Rack 3
- NVR-3
- NVR-4
Rack 4
- NVR-5
- Video Wall Controller (optional)
Rack 5
- UPS
- Power Distribution Unit (PDU)
Rack 6
- Patch Panels
- Spare Fiber
- Documentation
- Cable Labels
Best Practices
- Use CAT6 for camera-to-switch connections.
- Use Single-Mode Fiber (OS2) for uplinks between floors.
- Label every cable, patch panel, and switch port.
- Keep fiber separated from power cables.
- Protect all critical equipment with UPS units.
- Enable NTP so cameras and NVRs share the same time.
- Reserve spare switch ports and fiber strands for future expansion.
- Document IP addresses, VLANs, and rack layouts for easier maintenance.
Final Network Flow
300 Hikvision IP Cameras │ CAT6 │ Cable Managers (9 Floors) │ 48-Port PoE Switches │ SFP Modules │ Fiber ODFs │ Main Fiber ODF │ Cisco Catalyst C9300X-24Y │ 24-Port Gigabit Monitoring Switch │ CAT6 Patch Cables │ 5 Hikvision NVRs │ HDMI │ LCD / Video Wall │ Security Operators
Conclusion
A well-designed CCTV network is more than a collection of cameras—it's a structured infrastructure. By organizing each floor with a cable manager, PoE access switch, fiber ODF, and fiber uplink to a Cisco Catalyst C9300X-24Y core switch, you create a system that is scalable, reliable, and easier to maintain. Separating camera traffic with VLANs, using dedicated monitoring switches for NVRs, and keeping clear documentation will help ensure the surveillance system performs well both today and as it grows in the future.
