Solusi Pengawasan COFDM untuk Transmisi Video Nirkabel

In the field of surveillance and security, dapat diandalkan transmisi video nirkabel sangat penting. Traditional Wi-Fi or analog links often fail in jarak jauh atau tidak saling berhadapan (NLOS) lingkungan. This is where COFDM surveillance solutions stand out, menyediakan stabil, terenkripsi, dan transmisi video latensi rendah over challenging terrains.

Baru-baru ini, many customers have shown interest in implementing COFDM wireless technology untuk vehicle-mounted cameras, 360° surveillance systems, and control room monitoring. Let’s explore the key requirements dan itu hidden needs that often come with deploying a COFDM surveillance solution.

Hidden Needs for COFDM Surveillance Systems

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

1. Kualitas Video & Latensi

• Required resolution: HD, HD penuh, or 4K.
• Real-time response with latensi rendah (<100MS).
• Efficient compression (H.265/H.264) for better bandwidth usage.

2. Mobilitas & Stabilitas

• Support for high-speed vehicle movement (POLISI, militer, keadaan darurat).
• Doppler-resistant COFDM modulation for uninterrupted reception.

3. Power & Ruggedization

• Vehicle-compatible power supply (DC 12V/24V).
• Desain yang kokoh: tahan air, tahan debu, shock-resistant.

4. Control Room Integration

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

5. Keamanan & enkripsi

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

6. Skalabilitas

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

7. Kepatuhan terhadap Peraturan

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

8. Kemudahan Penerapan

• 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.
