Video Transmitter BLOW 78-561 (analog) - composite video output, 12V power compatibility

The BLOW 78-561 analog video transmitter is designed to transmit composite (CVBS) video signals over wired connections for CCTV and video monitoring systems. It converts and outputs an analog composite video signal and operates with a 12V power supply, making it suitable for integration into existing surveillance installations that use standard composite connectors.

Advantages

The transmitter supports standard composite video formats and provides a stable analog output for compatible cameras and recorders. Its 12V power compatibility simplifies installation in systems that use a common 12V supply. The compact design allows placement near cameras or inside enclosures, and the straightforward signal routing minimizes configuration time.

Suitable for

• Wired CCTV systems using composite (CVBS) cameras
• Upgrading or extending analog surveillance installations
• Integration with DVRs and monitoring equipment that accept composite input
• Environments where a simple, power-efficient analog transmitter is required

Key specifications

• Signal type: Analog composite video (CVBS)
• Video output: Composite video output compatible with standard RCA/BNC connections
• Power supply: 12V DC operation
• Mounting: Compact form factor suitable for near-camera installation or inside housings
• Compatibility: Designed for use with standard analog cameras and recorders

How to use

Connect the composite video source to the transmitter's input using the appropriate cable and connector (RCA or BNC as applicable). Supply 12V DC power to the transmitter from a compatible power source, ensuring correct polarity and stable voltage. Route the composite output to the recorder or monitoring device. Verify video signal presence on the receiving equipment and adjust cable connections if needed to ensure a clear analog image.

Usage recommendations

Use quality coaxial cable and proper connectors to minimize signal loss and interference. Keep power and video cabling separated from high-voltage or noisy electrical lines to preserve signal integrity. Confirm that connected devices accept composite (CVBS) input and that the 12V supply can provide adequate current for reliable operation.
