NVT Introduces 568B-Compliant, RJ45 Video-Input Passive Hubs; Distributed Power-Video-Data for CCTV Applications.MENLO PARK, Calif. -- Network Video Technologies (NVT NVT Niet Van Toepassing NVT Network Virtual Terminal NVT Network Video Technologies NVT Navegantes, Santa Catarina, Brazil (Airport Code) NVT Nederlands als Vreemde Taal NVT New Venture Theatre ) today announced that it has introduced a full range of passive video transmission hubs featuring RJ45 connectivity that are specifically designed for installers specializing in implementing digital-ready structured cabling systems in accordance with structured cabling standard EIA/TIA EIA/TIA Electronic Industries Alliance/Telecommunication Industries Association 568B. These new RJ45 video-input passive hubs let end-users and installers employ new or existing unshielded twisted pair See twisted pair.

It is much cheaper than standard "full-spec" Ethernet cable. wire (UTP UTP (uridine triphosphate): see uracil. (Unshielded Twisted Pair) See twisted pair. UTP - unshielded twisted pair ) to deliver a high quality picture while cutting costs and simplifying installation versus standard coaxial cable. "Installers are increasingly demanding a 568B standards-based connectivity solution," emphasizes Guy Apple, Vice President of Network Video Technologies (NVT). "They want the quickest, most modern way of connecting NVT equipment within their cabling plant so we designed our product range with RJ45 connectivity." The new NVT 568B-compliant, RJ45 video-input passive hubs now let installers standardize their structured cabling in accordance with 568B wiring protocols, reduce installation time, and fully prepare the plant wiring for future digital systems when desired. The NVT hubs deliver implementation flexibilities for installers, who can select among the 8-channel NV-813J, 16-channel NV-1613J, and 32-channel NV-3213J rack-mountable hubs with RJ45 video inputs for passive-to-passive multi-channel applications under 750 feet and passive-to-active multi-channel applications up to 3000 feet. According to Apple, these new hubs solve problems that installers face on a daily level. Coaxial cable is more difficult to install than UTP wire in most video transmission applications, resulting in higher labor charges and larger quotes for customers. In addition, coax systems do not comply with structured standards-based protocols such as 568B while UTP wire does. Contrary to coax, NVT's UTP video solutions also provide an ultimate migration pathway to an all-digital solution. NVT will exhibit the new RJ45 hubs at the ISC (1) (Internet Systems Consortium, Redwood City, CA www.isc.org) An organization founded by Paul Vixie, Carl Malamud and Rick Adams in 1994 and later sponsored by UUNET and other Internet companies. West Exposition, Booth 16085, in Las Vegas, April 6-8.

Background for Security Media Editors Outside of the security industry for the past 20-plus years, the telecommunications and data communications industries were responding to market needs with extremely different cabling standards. Token Ring ran on 150 ohm ohm (ōm) [for G. S. Ohm], unit of electrical resistance, defined as the resistance in a circuit in which a potential difference of one volt creates a current of one ampere; hence, 1 ohm equals 1 volt/ampere. Shielded Twisted Pair See twisted pair. (hardware) shielded twisted pair - (STP) A kind of cable used for most Ethernet cabling, especially fast ethernet connections such as 100 Mbps. Compare: unshielded twisted pair. , 3270 ran on RG-62 coax, and Ethernet ran on RG-58 coax. Telephone signals were transmitted on quad wire or 100 ohm unshielded twisted pair. All of these separate cabling standards added up to one big headache for installers and end-users. As more and more systems were installed, the mess grew larger and more out of control. There was no common wiring, bulky coax seemed to exist everywhere, and there was no way to organize and manage all of it. The result of all this chaos was a common cabling system standard that would accommodate all applications in datacom and telecom. That standard is now known as the EIA/TIA-568B. There are a number of suppliers of UTP-based CCTV CCTV abbr. closed-circuit television CCTV closed-circuit television solutions and this type of video transmission technology is now firmly rooted as a transmission option between coax and fiber. In an effort to supply the end-user with an open system cabling solution, we have recently released what we call the PVD PVD abbr. peripheral vascular disease PVD Peripheral vascular disease, see there (Power-Video-Data) product range. This PVD range of products lets low-voltage power, CCTV video, and Pan/Tilt/Zoom telemetry telemetry Highly automated communications process by which data are collected from instruments located at remote or inaccessible points and transmitted to receiving equipment for measurement, monitoring, display, and recording. (data) share a 4-pair UTP cable out to the camera while leveraging the positive aspects of a structured cabling network architecture. All models feature RJ-45 connectors. The products' RJ-45 wiring pin outs are compatible with the datacom and telecom industry standard EIA/TIA-568B, so termination mistakes are minimized. Additionally, with the exception of 24 VAC (Volts Alternating Current) See volt and AC. , these signals may share the same wiring backbone as other signals, such as telecom and datacom. |
