|Connecting several pairs of units via the same UTP cable can lead to transmission problems due to crosstalk of the different signals in the cable. Ideally, therefore, each device connection is realised via separate cables.
If several cables have to be lined up on a connection route, it is important that these transitions are technically as good as possible. I.e. ideally, professionally assembled RJ45 plugs are used for the transitions. If this is not possible, e.g. when using telephone cables, care should be taken to ensure that the stranding of the wire pairs is kept to a minimum. The contact between the cores of the cables to be connected must be galvanically as good as possible.
Shielded UTP cables can cause problems due to potential equalisation currents. Especially when several cables are brought together in a central unit, we recommend not earthing the shields in the central unit.

|The UP-EXT-SET units allow connection via data cable Cat5e or better, via coaxial cable or via paired cable such as telephone cable. Accordingly, both interfaces are also available on the extenders. For transmission via telephone cable, the supplied BNC to two-wire terminal adapter is used.
Important: Only one of the interfaces can be used at a time.
Transmission via coaxial cable: BNC socket (female)
Transmission via telephone cable: BNC socket and supplied adapter
Transmission via data cable: RJ45 socket
|Data cable Cat5e or better, via RJ45 socket
Coaxial cable, via BNC socket
Paired cable, e.g. telephone cable, via BNC socket and BNC to two-wire adapter
|The maximum transmission distance when using the above cable types is approx. 300m.
The maximum data rate is between 90MBit/s and 10MBit/s.
The possible data rate depends on the distance, the cable type, the core cross-section and the cable quality.
The following parameters have a positive effect on the possible data rate: Short cable length, high-quality cable type (coax > Cat7 > Cat6 > Cat5e > telephone cable), large core cross-section.
The PoE power available at the camera side decreases continuously with increasing distance. Furthermore, the available PoE power depends on the wire cross-section. Coaxial cables have small wire cross-sections. Data cables are available with different core cross-sections. The AWG number describes the wire cross-section. The smaller the AWG number, the larger the wire cross-section. The PoE input voltage has a great influence on the available PoE power. If possible, the voltage should be set as high as possible, maximum 57VDC.
With coaxial cables, the maximum PoE power after 200m is less than 10W.
With Cat7 cables with AWG24, the maximum PoE power after 200m is approx. 20W.
