Hidden Needs for COFDM Surveillance Systems

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

1. Calidad de vídeo & Estado latente

• Required resolution: alta definición, Full HD, or 4K.
• Real-time response with baja latencia (<100Sra).
• Efficient compression (H.265/H.264) for better bandwidth usage.

2. Movilidad & Estabilidad

• Support for high-speed vehicle movement (policía, militar, emergencia).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. Fuerza & Robustez

• Vehicle-compatible power supply (DC 12V/24V).
• Diseño robusto: impermeable, a prueba de polvo, shock-resistant.

4. Control Room Integration

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

5. Seguridad & encriptación

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

6. Escalabilidad

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

7. Cumplimiento normativo

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

8. Facilidad de implementación

• 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.
