DELTA BNC Female to RCA Male Adapter - 75 Ohm Coaxial Video Signal Converter for CCTV and Analog Systems

In a CCTV control room, a technician needs to connect a legacy BNC camera cable to a DVR with RCA inputs. This DELTA adapter screws onto the BNC socket and provides a male RCA plug, bridging the gap without signal loss. Its nickel-plated brass body and PTFE insulator ensure a stable 75-ohm path for composite video, so the picture stays clear and interference-free.

Key specifications

• Connector A: BNC female (socket) – standard twist-lock for secure coaxial connections
• Connector B: RCA male (plug) – compatible with common cinch jacks on monitors, DVRs, and capture cards
• Impedance: 75 Ohm – matches coaxial video cable impedance for minimal reflection
• Body material: Nickel-plated brass – rugged and corrosion-resistant
• Contact plating: Nickel – low contact resistance and durable mating cycles
• Insulator: PTFE – excellent dielectric properties for high-frequency signals
• Design: Straight adapter – compact and easy to install in tight spaces

Why choose it

This adapter eliminates the need for custom cables or re-termination. It converts a BNC socket to an RCA plug instantly, making it ideal for integrating older analog cameras with modern recording equipment. The all-metal construction withstands frequent plugging and unplugging, and the nickel plating resists oxidation, ensuring long-term reliability in security installations.

Ideal use cases

• Connecting CCTV cameras with BNC outputs to DVRs or monitors with RCA inputs
• Adapting test equipment or video sources in broadcast and AV setups
• Extending legacy analog video systems without replacing existing cabling
• Quick field repairs and temporary connections in security or event production

Good to know

The adapter is plug-and-play – no tools or soldering required. It supports composite video signals and is compatible with standard 75-ohm coaxial cables. For best results, ensure both connectors are clean and firmly seated. This adapter is not intended for high-power RF applications; it is designed for baseband video frequencies.
