Hidden Needs for COFDM Surveillance Systems

While customers usually list the basics, many critical requirements are not mentioned explicitly. A professional COFDM surveillance solution should consider the following:

1. ビデオ品質 & レイテンシ

• Required resolution: HD, フルHD, or 4K.
• Real-time response with 低遅延 (<100ミズ).
• Efficient compression (H.265/H.264) for better bandwidth usage.

2. モビリティ & 安定性

• Support for high-speed vehicle movement (警察, 軍隊, 緊急).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. 力 & Ruggedization

• Vehicle-compatible power supply (DC 12V/24V).
• 頑丈な設計: 防水, 防塵, shock-resistant.

4. Control Room Integration

• Multiple output formats: HDMI, SDI, IPストリーム (RTSP/UDP).
• Option for multi-channel reception to monitor several vehicles simultaneously.

5. 安全 & 暗号化

• AES-128/256 encryption for secure video feeds.
• Authentication to prevent interception of surveillance data.

6. スケーラビリティ

• Expansion to cover multiple vehicles and personnel.
• COFDM Mesh Networking or relay mode for extended range.

7. 規制の遵守

• Legal operation within the AS923-1 frequency band.
• Certification and licensing support for local regulations.

8. Ease of Deployment

• Plug-and-play setup with existing security infrastructure.
• Portable handheld receivers for security staff in the field.
• Software integration with NVR systems or cloud-based monitoring.
