Hidden Needs for COFDM Surveillance Systems

While customers usually list the basics, many critical requirements are not mentioned explicitly. 一个 professional COFDM surveillance solution should consider the following:

1. 视频质量 & 潜伏

• Required resolution: HD, 全高清, or 4K.
• Real-time response with 低延迟 (<100女士).
• Efficient compression (H.265 / H.264) for better bandwidth usage.

2. 移动性 & 稳定

• Support for high-speed vehicle movement (警察, 军队, 紧急情况).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. 功率 & 坚固化

• Vehicle-compatible power supply (DC 12V/24V).
• 坚固耐用的设计: 防水, 防尘的, 抗震.

4. Control Room Integration

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

5. 安全 & 加密

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

6. 可伸缩性

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

7. 合规

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

8. 易于部署

• 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.
