The ST-8008R is a 8 channel active(amplified) distribution amplifier device that allows the transmission
of real-time monochrome or color video on up to one mile(1.6km) using Category Unshielded Twisted-Pair(UTP) wire.
 
The 8 channel distribution amplifier hub features dual outputs per channel for large high-density applications.
1U rack-mountable active receiver distribution amplifier hubs provide signal conditioning in the form of ground-lifting,
distance EQ, and transient protection.
 
The unparalleled interference rejection and low emissions allow long run video signals to co-exist in the same wire
bundle as telephone, datacom, or low-voltage power circuits. This allows the use of shared or existing cable plant.
Ground-lifting ensures no annoying “hum-bars” when ground potential differences exist. With built-in transient
protection, damaging voltage spike problems are eliminated. Perfect for larger CCTV installations where port density
and camera number growth are prevalent.
