Security System Planning Guide
A comprehensive guide to planning an effective security camera system for your home or business.
Types of Cameras
- •Bullet Cameras: Best for long-distance viewing, outdoor areas, and parking lots. Visible deterrent with weather-resistant housing.
- •Dome Cameras: Ideal for indoor use, retail stores, and wide-area coverage. Discreet design with vandal-resistant options.
- •PTZ Cameras: Pan-tilt-zoom capabilities for large areas requiring active monitoring. Can cover multiple zones with one camera.
- •Turret Cameras: Combines benefits of bullet and dome cameras with flexible positioning and no glare issues.
Strategic Placement
Entry/Exit Points
Cover all doors, gates, and access points. Height: 8-10 feet for facial recognition.
High-Value Areas
Safes, inventory storage, cash registers, and equipment rooms require dedicated coverage.
Perimeter Coverage
Parking lots, building perimeter, and blind spots need wide-angle or overlapping views.
Lighting Conditions
Consider IR night vision for low-light areas. Avoid pointing cameras directly at bright lights.
Storage Capacity Planning
Factors Affecting Storage Requirements:
- • Number of cameras and resolution (1080p, 4K)
- • Frame rate (15, 20, or 30 FPS)
- • Compression format (H.264, H.265)
- • Retention period (7, 14, 30, or 90 days)
- • Motion-based vs continuous recording
NVR/DVR Selection
Network Video Recorder (NVR): For IP cameras. Offers better image quality, easier installation, and PoE power. Recommended for new installations.
Digital Video Recorder (DVR): For analog cameras. More cost-effective for existing analog systems but limited scalability.
Example Storage Calculation:
8 cameras × 4MP resolution × 24/7 recording × 30-day retention = approximately 6-8TB of storage required
Network Infrastructure
- •Bandwidth Requirements: 2-4 Mbps per camera for remote viewing. Consider total upload speed for multiple simultaneous viewers.
- •PoE Switch: Power over Ethernet simplifies installation by combining power and data over one cable. Ensure sufficient wattage per port (15W-30W).
- •Network Segmentation: Create a dedicated VLAN for security cameras to improve performance and security.
Remote Access Setup
Mobile Apps
Access live and recorded footage from your smartphone. Enable push notifications for motion detection alerts.
Web Portal
Browser-based access from any computer. Useful for multi-monitor viewing and detailed investigation.
Security Best Practices
Use strong passwords, enable two-factor authentication, keep firmware updated, and use VPN for remote access when possible.
