The eneo twisted pair series has been tried and tested in a multitude of projects and garantees reliable transmission. The installation of the right type of relay technology also depends upon the conditions at the relevant locations especially if existent cables are to be used.

Here are some recommendations:

Symmetric cable CAT2-5 (UTP) 24AWG (unshielded twisted two-core cable):
 

Transmitter // Receiver // Maximum distance
Passive // Passive // 225 metres (digital recording)
Passive // Passive // 350 metres (surveillance)
Passive // Active // 800 Metres (digital recording)

Passive // Active // 1000 metres (surveillance)
Active // Active // 1800 metres (digital recording)
Active // Active // 2200 metres (surveillance)

The use of a separate cable is recommended for each video signal. If several video signals are to be relayed using the same cable, the maximum coverage distances are substantially reduced. If existing cables are to be used, we recommend that the capacity of those cables be measured. The capacity should not be higher than 57pF per metre.
