No name TR-1 angular video transformer with BNC plug (model LEC-URZ0130)

No name TR-1 angular video transformer with BNC plug (model LEC-URZ0130) is a compact passive device designed for impedance matching and galvanic isolation in analogue video installations. The unit connects directly to BNC-terminated coaxial cables and helps correct signal level and reduce ground loop interference in short-distance video lines. Its right-angle BNC plug enables space-saving connections in cramped panels or behind devices.

Advantages

The angular design with an integrated BNC plug allows easy installation where straight connectors would be impractical. As a passive transformer, it does not require power and provides galvanic isolation between connected devices, which helps lower the risk of hum and interference caused by ground loops. Its small size makes it suitable for tight mounting locations and for inline correction of signal mismatches without altering existing cabling.

Suitable for

• CCTV camera connections in confined spaces
• Analogue surveillance system signal matching and troubleshooting
• Short-distance video line corrections between cameras and monitors or DVRs
• Situations requiring reduction of ground loop interference

Key specifications

• Connector type: right-angle BNC plug to BNC jack (inline transformer form)
• Function: passive video transformer for impedance matching and galvanic isolation
• Application: analogue composite video (CCTV) short-distance lines
• Construction: compact, low-profile housing suitable for tight installations
• Power: passive operation, no external power required

How to use

Insert the right-angle BNC plug into the BNC socket of the camera, monitor, DVR or extension lead, then connect the opposing BNC jack to the mating cable or device. Ensure connectors are securely fastened and that cable shielding and centers are properly seated for reliable contact. Use the transformer inline at the point of signal mismatch or where ground loop symptoms appear. No configuration or power connection is necessary.

Usage recommendations

For best results, use the transformer on short runs or near the point of connection where interference is observed. Avoid using multiple passive transformers in series. Inspect connectors for corrosion and ensure good mechanical contact; if long cable runs or active distribution are required, consider using active video baluns or amplifiers designed for longer distances.
