When planning network infrastructure for your business, the cabling category you choose today will impact performance for decades. Category 6A has emerged as the gold standard for future-ready networks, supporting 10-Gigabit speeds and beyond. But what exactly makes Category 6A special, and when should you invest in it?
What is Category 6A Cabling?
Category 6A (Cat 6A) is an enhanced version of Category 6 cabling that supports 10-Gigabit Ethernet (10GBASE-T) at full 100-meter distances. The "A" stands for "Augmented," referring to improved specifications that reduce crosstalk and increase bandwidth capacity to 500 MHz.
Key Specifications:
- Bandwidth: 500 MHz
- Maximum speed: 10 Gbps
- Maximum distance: 100 meters (328 feet)
- Connector: RJ45 (same as Cat 5e/6)
- Backward compatible with all previous categories

Why Choose Category 6A?
Future-Proofing Your Investment
Network infrastructure typically lasts 15-20 years. Installing Cat 6A today ensures your cabling won't become a bottleneck as network speeds increase.
Full 10-Gigabit Performance
Unlike Cat 6, which supports 10 Gbps only up to 55 meters, Cat 6A maintains full 10-Gigabit speeds across the entire 100-meter channel.
Reduced Crosstalk
Enhanced shielding and improved pair separation significantly reduce alien crosstalk (AXT), ensuring reliable performance in high-density installations.
Business Benefits of Cat 6A
- Supports current and future bandwidth demands
- Enables high-speed data transfer for large files
- Supports advanced PoE+ applications
- Reduces need for future cable replacement
- Improves overall network reliability
Cat 6A Installation Considerations
Cable Construction Differences
Cat 6A cables are physically larger than Cat 6 due to additional shielding and insulation:
- Diameter: Approximately 30% larger than Cat 6
- Weight: About 50% heavier per foot
- Bend radius: Larger minimum bend radius required
- Fill ratio: Fewer cables per conduit
Pathway Planning Requirements
Conduit Fill Calculation:
- Cat 6: ~11 cables per 1" conduit
- Cat 6A: ~7 cables per 1" conduit
- Plan conduit size accordingly to meet NEC requirements

Planning an IP camera surveillance system requires more than just placing cameras randomly around your facility. Effective video security systems require strategic planning, proper equipment selection, and expert installation to eliminate blind spots and provide reliable evidence when needed. This comprehensive guide covers everything you need to know about designing a professional IP camera system.
Why Proper Camera System Design Matters
A poorly designed camera system is worse than no system at all—it creates false security confidence while leaving critical areas unprotected. Professional system design ensures:
- Complete coverage with no blind spots
- Usable evidence with proper resolution and lighting
- Reliable operation in all environmental conditions
- Scalable architecture for future expansion
- Compliance with insurance and regulatory requirements
Phase 1: Security Assessment and Coverage Planning
Threat Assessment
Before placing a single camera, identify what you're protecting against:
| Security Concern |
Camera Requirements |
Coverage Strategy |
| Perimeter Security |
Wide-angle, night vision |
Overlapping fields of view |
| Asset Protection |
High resolution, zoom capability |
Direct line of sight to valuables |
| Employee Safety |
Audio capability, two-way communication |
Common areas, parking, entrances |
| Loss Prevention |
Covert options, analytics |
Point-of-sale, inventory areas |
Critical Coverage Zones
Every business should monitor these areas:
- Entry/Exit Points: All doors, gates, loading docks
- Perimeter: Property boundaries, parking areas
- Cash Handling: Registers, safes, counting rooms
- High-Value Assets: Inventory, equipment, servers
- Common Areas: Lobbies, break rooms, hallways
- Vulnerable Spots: Blind corners, isolated areas
Camera Selection and Specification
Resolution Requirements
Resolution determines the quality of evidence your system can provide:
PPF (Pixels Per Foot) = Camera Resolution ÷ Field of View Width
PPF Guidelines for Different Applications:
- Monitor (general surveillance): 20-30 PPF
- Recognize (identify known person): 40-50 PPF
- Identify (identify unknown person): 80+ PPF
- License plates: 120+ PPF
Lens Selection
Lens focal length determines field of view and identification capability:

Network Infrastructure Requirements
Bandwidth Planning
IP cameras consume significant network bandwidth. Plan accordingly:
Typical Bandwidth Usage:
- 2MP (1080p): 2-6 Mbps per camera
- 4MP: 6-12 Mbps per camera
- 8MP (4K): 15-25 Mbps per camera
Network Planning Formula:
Total bandwidth = (Number of cameras × Average bitrate) × 1.3 (overhead factor)
PoE (Power over Ethernet) Considerations
Most IP cameras use PoE for both power and data:
- PoE (802.3af): 15.4W - Basic cameras
- PoE+ (802.3at): 30W - PTZ cameras, heaters
- PoE++ (802.3bt): 60-100W - High-power PTZ, lighting
Storage and Recording Systems
Storage Calculation
Calculate storage requirements based on retention needs:
Storage (TB) = (Bitrate × 3600 × 24 × Days × Cameras) ÷ 8,000,000,000
Example Calculation:
- 20 cameras at 4 Mbps each
- 30-day retention requirement
- Storage needed: (4 × 3600 × 24 × 30 × 20) ÷ 8,000,000,000 = 25.9 TB
- Recommended: 32TB with RAID redundancy
Compliance and Legal Considerations
NDAA Compliance
Federal contractors and security-conscious businesses must use NDAA-compliant cameras:
Prohibited Manufacturers (Section 889):
- Hikvision and subsidiaries
- Dahua and subsidiaries
- Hytera Communications
- Hangzhou Hikvision
- Zhejiang Dahua Technology
NDAA-Compliant Alternatives

- Loose Tube: Outdoor installations, better moisture protection
- Armored: Rodent protection, direct burial
- Plenum-rated: Air handling spaces, fire safety compliance
Network Architecture Design
Centralized vs Distributed Architecture
Centralized Fiber Architecture:
- All fibers terminate at central location
- Easier management and troubleshooting
- Higher fiber count requirements
- Best for new installations
Distributed Architecture:
- Intermediate connection points
- Lower initial fiber counts
- More complex management
- Good for phased deployments
Fiber Count Planning
Current and Future Needs Assessment
Proper fiber count planning prevents costly additions later:
Minimum Fiber Count = (Current Needs × 2) + Future Growth (50-100%)
Example Calculation:
- Current requirement: 12 fibers
- Working fibers: 12 × 2 = 24 fibers
- Growth allowance: 24 × 1.5 = 36 fibers
- Recommendation: 48-fiber cable (next standard size)
