NVT.
In 1990, Dan Nitzen, the future owner and president of NVT, was asked by a friend who worked at Apple to develop a solution that would enable videoconferencing for several employees of an engineering group located in different locations. Nitzen eventually came up with a multimedia device that fully met the needs of the project. A few weeks later, another company approached him with a request to organize a similar solution for its employees at the New York Stock Exchange. The project was large enough that Dan was able to leave his previous job and fully concentrate on the development of technologies for transmitting video data over a network (Network Video Technologies – NVT).
In the first years of its existence, the company's main field of activity was the US market, where NVT soon achieved wide recognition and popularity among security system installers. Growing interest in the company's products led to an expansion of the sales market, and in 2002 a representative office was opened in the UK, responsible for work in Europe, Russia and the CIS countries, Asia and Africa. The official appearance of NVT in the post-Soviet space took place in April 2005, when partnership agreements were signed with STA, which has since represented NVT's interests in Russia, Ukraine and the Baltic countries.
NVT equipment enables the user to connect video cameras, recorders and control devices using a data transfer method that ensures the highest possible image quality and system reliability even under the most adverse operating conditions. The company produces a wide range of products that are currently recognized by industry experts as the best in their class.
The high quality and technical level of NVT equipment has been confirmed by numerous completed projects around the world, including the new Heathrow Airport terminal in London, where video, power and data transmission equipment was used for 2,500 video cameras, Olympic sports facilities in Turin, an oil refinery in Omsk, buildings of the Central Bank of Russia, as well as shopping and business centers in major European cities, including Moscow.
A choice
NVT's goal is to provide customers with choice. This choice allows them to use UTP instead of coaxial or fiber optic cable, or existing high-quality analog video cameras instead of expensive IP cameras with low performance characteristics. NVT equipment allows customers to choose the best methods for migrating to structured cabling systems and IP networks. The company's specialists fully support their customers and train them on the use of existing analog devices, connecting these devices via structured cabling systems, integrating them into IP networks, or even completely migrating to IP networks, if required.
NVT's twisted pair video, power and data (PVD) equipment allows the customer to organize remote power supply for video cameras, as well as significantly reduce the cost of laying separate cables for transmitting video and control data. All current NVT products use a cable infrastructure based on unshielded twisted pair to ensure organized system management in accordance with the requirements of the facility.
Technologies
To create a robust, reliable and practical surveillance system, NVT designs equipment that is guaranteed to work in a variety of conditions. Unlike conventional video baluns, NVT products incorporate a variety of technical features that provide unrivaled performance.
When video cables are routed near potential noise sources such as low voltage power cables, data cables, or communication cables, baluns often do not provide sufficient noise immunity due to the inherent crosstalk in the cable. Unfortunately, their function is limited to signal balancing. One of the main advantages of NVT products is their unrivaled noise immunity. When measuring noise immunity in terms of common mode rejection ratio, most baluns provide 30 dB of common mode rejection ratio. NVT's patented technology provides 60 dB of common mode rejection ratio over a wide video frequency range (15 kHz to 5 MHz).
Video surveillance equipment is often at risk of failure due to overvoltage or lightning strikes, which entails significant costs for replacing components. NVT devices have a seven-level lightning protection system, which includes a high-current avalanche diode of low capacitance, a gas-discharge device and multi-stage filtering using series inductances and shunt capacitors. This allows you to protect both video cameras and expensive digital video recording equipment from failure. The highest level of reliability of all NVT equipment is confirmed by the ANSI/IEEE 587 C62.41 certificate.
Prospects
NVT's business is growing rapidly around the world in the markets of North America, Europe, Russia, the Middle East, South Africa, Latin America and Asia. The use of unshielded twisted pair cable has become widespread as a reliable method of transmitting video signals in closed-circuit television systems, and NVT continues to develop high-quality equipment for its customers, providing cost-effective and timeless solutions.
