The Z-Band system uses RF video over UTP (CAT 5, CAT 6 ) in the horizontal thereby eliminating the cost of installing coax. The extra cost of coax is more than just the cost of the wire. Common practice is to have a separate conduit, tray or plenum, which all add significant costs for both the material and labor to the installation when compared to RF video delivered over UTP.
-
The Z-Band system is simple to configure versus coax, or a passive twisted pair cabling video distribution system, which requires multiple splitters, combiners, taps, and amplifiers as well as significant calculations which continuously change as the system ages or personnel make adds, moves or changes.
-
The Z-Band system is extremely scalable whereby one can add tens to thousands of drops (outlets) within a radius of 2000 feet from a building's main RF distribution "hub" with a minimum of design and installation cost.
-
The Z-Band system has an active one-piece RF video distribution hub which contains patented technology that automatically adjusts for gain and slope thereby maintaining quality (both signal level and signal-to-noise ratio) to all drops and across all channels on your UTP network. Typical passive systems do not have slope adjustments, which means they either can’t distribute all channels over the length of 100 meters or they broadcast at such high levels that the system radiates. This in turn can cause interference in other systems or “ghosts” in the RF video system.
-
From any drop, up to 14,000, The Z-Band customer can simultaneously input, modulate multiple RF video channels back into the system (assuming those channel are available) without the need to make wiring adjustment or connect special equipment to change the channel frequency from a “T-Channel" to a broadcast channel.

- Maintenance over time is nominal whereas the coax system needs to have system adjustments by someone very competent in RF video systems. If the coax system is not recertified (this requires actual and updated building drawings which is not a realistic requirement with changes in personnel and priorities) the customer will eventually experience deteriorations of picture quality. This is not a problem with the Z-Band system due to its continual automatic gain and slope adjustments.
- The Z-Band system is designed to simultaneously carry voice (both analog/digital telephone, VoIP, and data) or auxiliary signals such as camera’s pan, tilt, and zoom functions on the two unused pair of the same sheath of CAT 5e and or CAT 6 sheath. The system has been tested to insure that there is no interference between data/voice and video over UTP.
- The Z-Band system can be easily connected to a personal computer to both receive broadband video (tuner card/USB port) and input video into the system (accelerated graphics card-AGP). This gives the system the capability to broadcast “streaming video” from the web to all viewers without impacting the LAN nor involving anyone from the IT department for a special “multi-cast” distribution. Again, all this runs over your existing UTP cable.
