The TR-1P+1AU/50 device allows transmission of video, audio and power using UTP/STP cable. For video signal the device adjusts 75 ohms coaxial cable impedance to twisted pair cable impedance. It guarantees video signal transmission up to 400 meters. For the audio signal the device adapts 600 ohms microphone impedance to twisted pair impedance. It guarantees audio signal transmission up to 1200 meters. The video and audio signals utilize two twisted pairs of UTP/STP cable, whereas the next two are used for conveying supplying voltage. For 12 V DC source, assuming that a camera needs 235 mA and associated thermostat 500 mA (TT-12E), the supplying voltage can be sent over next distances:
  • 50m - camera without thermostat
  • 15m - camera with thermostat.
When longer distances have to be used, the proper solution is to employ the set consisting of supplier ZK-40, stabilizer SK-40, and transformer TTS-80. When applying two pairs of wires from UTP/STP cable, possible distances are given in tables.To build complete path for signal transmission, two devices are needed. One of them works as a transmitter and the second as a receiver. Audio insertion loss for 1200 meters (two devices + line) is 6 dB. Audio-Video signal transmission by twisted pair cable is cheaper than transmission by coaxial cable, and assuring good quality because the signal is transmitted differentially.
Cooperating audio module can be connected to lead frame or to chinch socket. It is important to connect properly supplying voltage: (+) and (-). Reverse polarity could destroy employed camera. Improper connection of video signal will cause interferences. The device is equipped with LED informing about correct connection of supplying voltage. Parameters that are given concern 5-th category UTP/STP cable with copper conductors of diameter 0.5mm (24 AWG).
