Product information

Description

TR-4M by No name is a compact video transformer designed to transmit and isolate analog video signals in CCTV and video monitoring systems. The TR-4M provides galvanic isolation and impedance matching to reduce interference and prevent ground loops on long cable runs or when connecting equipment with different grounding potentials. It is intended for installations where maintaining signal integrity over coaxial or twisted-pair cabling is important.

Advantages

The TR-4M offers galvanic isolation that helps eliminate hum and ground loop noise without affecting signal amplitude. Its impedance matching reduces reflections and signal loss across connections between cameras, recorders, and distribution equipment. The device is compact and simple to integrate into existing systems, supporting reliable transmission over extended cable lengths and improving overall video signal quality in analog surveillance setups.

Suitable for

Analog CCTV camera installations
Video signal distribution between camera and recorder
Long coaxial or balanced cable runs
Ground loop and interference mitigation in monitoring systems

Key specifications

Function: video signal isolation and impedance matching
Signal type: analog composite video
Primary benefit: galvanic isolation to prevent ground loops
Mounting: inline or within junction boxes in surveillance wiring
Compatibility: typical CCTV camera and recorder video interfaces

How to use

Install the TR-4M inline on the video feed between the camera and receiving device, making sure input and output connections correspond to the camera output and the recorder or monitor input. Use appropriate coaxial connectors or balanced twisted-pair wiring adapters as required by the installation. Verify correct orientation and secure physical mounting to prevent strain on cable connections. After installation, check video signal for proper levels and absence of ground loop hum or interference.

Usage recommendations

For best results, use the TR-4M in locations where cable runs are long or where equipment is powered from different circuits. Combine with appropriate shielding, grounding practices, and quality cabling to maximize interference reduction and maintain consistent video quality.
