Data Transmission Solutions for CCTV
Whether we look at large corporations or SME’s, camera and communication systems are a must-have to Prevent, Observe and Secure. However, that is not all: We expect Quality, Speed and High Definition (4K). All benefits Nitek provides in suitable Data Transmission Solutions for your enterprise. Nitek is a manufacturer of Video, Audio and Data Transmission Solutions for the security market with its own Research and Development Department in the USA. Nitek’s Security Data Transmission Network Solution is essential in our society nowadays. Reliable Data Transmission Network Solutions are possible in both small and larger businesses. Think of large Data Centre Companies for example, as well as Internet Companies, Airports and Shopping Malls. Even SME’s require reliable and high speed Data Transmission Solution Networks.
Understanding the PoE limitation and voltage drop which occurs over longer length of cable becomes critical when attempting to power IP edge devices with PoE from the headend. Nitek’s Etherstretch™ product line is designed to extend 10/100 network communication and PoE well beyond standard network limitations. Voltage drop is a natural occurrence which is best described as how energy is reduced or lost as electric current moves through resistant conductors of an electrical circuit. As the distances of cable get longer the supplied voltage will become less. The Etherstretch product line is designed to support communications over coax up to 500 meters and over Category UTP cable to 600 meters. Electrical wiring such as coax and category UTP each have a resistance value and based on the gauge and material will fall victim to the effect of voltage drop on long circuits. Nitek has done thorough testing and documentation on voltage drop when deploying Etherstretch™ which can be found in each of the product specification sheets. The charts below will indicated the available wattage for the connected device based on distance and cable type.
Download WhitepapersWith 1,800 thunderstorms in progress at any given time on Earth, some of the most unpredictable disruptions to the proper operation of a security system are lightning strikes and electrical surges. Voltage surges have a huge destructive impact upon IP video and data systems each year. Many components such as IP cameras, VoIP emergency phones, LED illuminators, wireless access points along with other integrated security products are vulnerably mounted outdoors and exposed to the environment. The placement and location of these devices along with the continuity of service is essential to preserving safety and security, which is why it is crucial that these devices are protected against lightning and overvoltage. The vulnerability of electronic video systems to overvoltage is widely recognized by insurance companies and research institutes and supported in technical literature and different regulations along with standards which specify the need for lightning protection. This white paper explains the causes of overvoltage generated from surges, spikes and transients and how they damage electronic devices prematurely, or more importantly increase service interruption in life safety systems. It also covers the legal and regulatory framework governing protection, and proposes a solution to maximize protection performance and continuity of service.

These solutions enhance the installation of a video management system while reducing the amount of time and devices necessary for deploying, configuring and programing the system. Most of these solutions provide a streamlined plug-n-play configuration using imbedded VMS software.
Privately distributed IPTV systems (such as in hotels, health care facilities or college campuses) continue to grow in popularity by empowering organizations large and small to deliver live and recorded video, on a scheduled or on-demand basis, to computers, televisions and mobile devices while hosting hospitality specific added features and programming.
The biggest obstacle most property managers are faced with when implementing IP-based video and TV distribution systems is the cost associated with re-cabling. Most existing television distribution systems were implemented using standard RF equipment and coaxial cables.
IPTV is sensitive to packet loss and delays if the streamed data is unreliable. IPTV has strict minimum speed requirements in order to facilitate the right number of frames per second to deliver fluid, uninterrupted video images. This means that limited connection speed and available bandwidth for a large IPTV system can reduce the service quality being delivered.
