Using the amplifier 346870 enables
creating systems using twisted cables
longer than 50 m (max 100 m) Its use
is ideal for refurbishment and repair
of already existing systems
The signal amplifier must be
used with non twisted, non
polarized cables, with a section of
≥0 28 mm
2
The signal amplifier must be
installed at approximately 50
metres from the entrance panel
(or camera) Shorter distances
may cause distortion of the video
signal, while longer distances
would make it useless When using
audio/video node F441, in order
