Benefits of NVT’s UTP CCTV Video Transmission Technology

Unshielded Twisted-Pair (UTP) Structured Premise Cabling permits many communication protocols to reside in the same wire bundle. Examples include voice, data, and CCTV video and control. Benefits of structured UTP cabling include:

• Better interference rejection than coax
• UTP is less expensive than dedicated coax or fiber
• Color-coded cabling
• Unlimited bend radius
• Physically smaller than coax
• Easiest media to install and reconfigure
• UTP is extremely easy to terminate
• In many cases, the wire is already installed

History

For at least 20 years products have been available capable of transmitting video using UTP wire. For much of that time however, UTP balun manufacturers did little more than convert an unbalanced coax signal to a balanced signal for use on the twisted pair. Some companies added gain to extend the distance. Unfortunately, these devices provided inadequate noise immunity, no ground loop isolation, and no surge protection. The security market viewed this older technology as "last resort" until NVT developed its range of high performance UTP CCTV products.

State of the Art

NVT has developed a technique of rejecting noise and interference. This allows the NVT video signals to reside in the same wire bundle with ringing telephones, Ethernet, 24VAC, RS-422 or RS-485 data, multiple video signals, etc. Unlike coax, it can also reside in high-noise environments, such as elevator traveling cables, or near fluorescent lights, radio transmitters, motors or generators.

NVT Compared to Coax Video

• Total interference immunity
• Most models have built-in Surge Suppression
• Active models have Ground Lifting
• Active models have built-in Distance Equalization control for crisp video at all distances
• Transmission distances up to one mile or more

NVT Compared to Fiber

• NVT is a lower cost solution at most distances and applications
• Simple termination and installation
• Installation tools, test equipment, and labor are less expensive
