- Application Scenario
- Şunun için tasarlandı: land-based surveillance and security: Araçlar, ground personnel, and control centers.
- Frekans Bandı
- Must comply with AS923-1 frequency band (used across Asia-Pacific for wireless communication).
- Customized Frequency, we can do the working frequency from 170-6000MHz for you.
- İletim Aralığı
- Maximum possible long-range wireless video transmission.
- Clarification needed for both Görüş Hattı (LOS) ve Görüş Hattı Dışı (NLOS) coverage.

Hidden Needs for COFDM Surveillance Systems
While customers usually list the basics, many critical requirements are not mentioned explicitly. bir professional COFDM surveillance solution should consider the following:
İçindekiler
1. Video Kalitesi & Gecikme
- Required resolution: HD, Tam HD, or 4K.
- Real-time response with düşük gecikme (<100MS).
- Efficient compression (H.265/H.264) for better bandwidth usage.
2. Mobility & Kararlılık
- Support for high-speed vehicle movement (polis, askeri, emergency).
- Doppler-resistant COFDM modulation for uninterrupted reception.
3. Güç & Sağlamlaştırma
- Vehicle-compatible power supply (DC 12V/24V).
- Rugged design: su geçirmez, toz geçirmez, shock-resistant.
4. Control Room Integration
- Multiple output formats: HDMI, SDI, IP akışı (RTSP/UDP).
- Option for multi-channel reception to monitor several vehicles simultaneously.
5. Güvenlik & Şifreleme
- AES-128/256 encryption for secure video feeds.
- Authentication to prevent interception of surveillance data.
6. Ölçeklenebilirlik
- Expansion to cover multiple vehicles and personnel.
- COFDM Mesh Networking or relay mode for extended range.
7. Mevzuata Uygunluk
- Legal operation within the AS923-1 frequency band.
- Certification and licensing support for local regulations.
8. Dağıtım Kolaylığı
- 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.
Example of a Complete COFDM Surveillance Solution
İyi tasarlanmış COFDM surveillance system for land use may include:
- COFDM Verici: Mounted on vehicles with 360° PTZ or panoramic cameras.
- COFDM Alıcısı: Installed in the control room with HDMI/IP output to large displays or video servers.
- Mobile Receivers: Portable units for ground security teams.
- Mesh or Relay Nodes: To extend long-range wireless video transmission in NLOS environments.
- Şifreleme & Güvenlik: AES-256 to ensure data protection.
- Frequency Compliance: Fully tuned for AS923-1 frequency band operasyon.
Çözüm
When planning a COFDM surveillance solution, customers should not only focus on transmitters and receivers but also consider:
- Video quality and latency for real-time decision-making.
- Encryption and frequency compliance for secure and legal operation.
- Scalability and integration with control rooms and mobile teams.
By addressing these hidden needs, A COFDM-based long-range wireless video transmission system can deliver stabil, güvenli, and mission-ready surveillance performance, whether in görüş hattı veya görüş hattı olmayan ortamlar.
If you are exploring COFDM surveillance solutions using AS923-1 frequency band or other customized frequency, consider the complete ecosystem — transmitters, alıcılar, network integration, and regulatory compliance — to achieve maximum efficiency and reliability.
We currently customize two products according to the customer’s demand on COFDM Surveillance Solution for Wireless Video Transmission.
