TWISTED PAIR
Low Cost Twisted Pair Video Conver ter Kit
These economically priced twisted pair video balun's make the use of twisted pair cable an
affordable reality for CCTV installations.They also allow the transmission of video up to distances of 1000 metres. Both transmitter and receiver feature BNC connectors which allow
them to be easily connected to a camera, monitor, mux or DVR.
Their compact size also means they can be fitted into camera housings and used in areas
of limited space.At the rear of each balun is a screw terminal for connecting the twisted pair
cable and 12VDC power. Adjustments are possible on the receiver, depending on the transmission distance.The variable pot adjusts the colour and brightness.

4 Channel Twisted Pair Video Transmission Kit
This set of twisted pair video transmission equipment consists of a 4 channel co-ax to twisted pair transmitter and a 4 channel active receiver. It allows one to transmit 4 individual composite video signals over a
single CAT5 UTP cable. Four channels of video are inputted on the transmitter side and four channels of
video outputted on the receiver side.
The transmission unit features 4 BNC connectors and an RJ45 connector for the CAT5. On the
receiver end, the unit has 4 BNC connectors for video output, an RJ45 connector for the CAT5 receiving end
and a 2.1mm DC socket for 12VDC power. Both units are extremely compact and easy to install. The receiver has adjustable gain settings for different ranges from 0~300 metres, up to 1200~1500 metres.

Twisted Pair to Co-Ax Receivers
These receivers receive a twisted-pair cable from a E-TWM1/TWT1 transmitter and converts it back
to a co-ax video signal.This can then be connected to a monitor, switcher or recorder. It can be supplied encased in an IP65 enclosure or for larger installations in 19" rack mount format. The rack
mount version includes a rack incorporating up to 10 Euro-card modules and a power supply.This
format helps keep an installation orderly and reduces unnecessary cables. Each Euro-card module
features a screw terminal block and BNC connector at the rear.
