The TR-1B is designed for video signal transmission from one source to the destination via twisted-pair cable.
The transformer has at a right angle BNC connector mounted. It allows to save the required place in case of the device connecting (e.g. camera or DVR).
The device matches the impedance of coaxial line (75Ω) to the impedance of symmetrical line, ensuring transmission of video signal up to 400m (twisted-pair cable category 5).
Schematic diagram is presented below. It is important to pay attention to linking the adequate terminals: (+) to (+) and (-) to (-). Reverse connection would cause distortion of images.

The basic advantage is the small dimensions of the transformer:
Twisted-pair cable connecting. The free pairs of wires can be used to: other transformers connecting, power sending to the camera or can be isolated:
