Description

• 4-in-1: This indicates the balun supports four types of video signals:

  1. CVI (Composite Video Interface): A standard for HD video transmission over coaxial cable. Common in CCTV systems.

  2. TVI (Transport Video Interface): Another HD video transmission standard similar to CVI, often used in surveillance systems.

  3. AHD (Analog High Definition): A type of analog HD signal, used for CCTV cameras that provide HD resolution.

  4. CVBS (Composite Video Baseband Signal): The traditional analog video signal used in older CCTV systems.

• Passive: No need for an external power source. It simply facilitates the transmission of video signals over the cable, unlike active baluns, which require power to boost or regenerate signals over longer distances.

• HD: High definition, which means the balun can transmit HD video signals (1080p or 720p) over long distances, typically over 300 meters (depending on the signal type).

• Twisted Pair Cable (Cat5e/Cat6): The balun allows you to send video signals via twisted-pair cabling, which reduces the cost of cabling and simplifies the installation process compared to coaxial cables.

Common Uses:

• Surveillance systems: These baluns are typically used in HD CCTV systems where you want to run long-distance video cables without needing expensive coaxial cabling.

• Upgrading old systems: They allow older analog systems (CVBS) to be upgraded to high-definition systems (CVI, TVI, AHD) without needing to completely replace the infrastructure.
