Installation/configuration notes
LTC 4641 and LTC 4642 Series
The LTC 4641 Series Transmitters and LTC 4642
Series Receivers are designed for transmission of
CCTV analog video signals. Efficient installation is
assured because there are no user adjustments
required. The wide bandwidth transmission capability
of these units enables clear, sharp black and white or
color pictures to be transmitted over long distances.
The compact transmitters are small enough to be
connected directly to a camera’s BNC connector,
thereby simplifying installation.
