Nvent Networks inc is a direct supplier of security cameras (analog CCTV, 720p and 1080p HD CCTV, 4K and network IP), video surveillance systems, and CCTV equipment (Closed Circuit Television). We supply video surveillance systems for home, business and government. We sell to end users, resellers, and installers. We started our company in 2006 specializing in CCTV camera systems. As technology advanced, we expanded our product offering to network IP cameras and HD security camera systems that use AHD cameras (analog high definition), HD-SDI, and TVI cameras. We also carry hundreds of video surveillance accessories such as DVRs, cables, connectors, tools, test monitors, and more.
Video surveillance systems that support with remote Internet viewing is our specialty. Most of our surveillance systems include DVR viewer software for Mac and Windows PCs, as well as mobile camera viewer apps for iPhone, iPad, and Android devices. We sell many complete systems that are pre-configured and easy to install.
A biometric system is a real-time identification system which identifies a person by measuring a particular physical or behavioural characteristic and later comparing it to a library of characteristics belonging to many people. Fingerprint and other biometric devices consist of a reader or scanning device, software that converts the scanned information into digital form, and wherever the data is to be analyzed, a database that stores the biometric data for comparison with previous records. When converting the biometric input, the software identifies specific points of data as match points. The match points are processed using an algorithm into a value that can be compared with biometric data scanned when a user tries to gain access. Thus biometric devices can be explained with a 3-step procedure. They are -A sensor takes an observation. The type of sensor and its observation depend on the type of biometrics device used. This observation gives us a ABiometric Signature of the individual.
-
A computer algorithm Anormalizes the biometric signature so that it is in the same format (size, resolution, etc.) as the signatures on the system's database. The normalization of the biometric signature gives us an ANormalized Signature of the individual.
-
A matcher compares the normalized signature with the set (or sub-set) of normalized signatures on the system's database and provides a Asimilarity score that compares the individual's normalized signature with each signature in the database set (or sub-set). What is then done with the similarity scores depends on the biometric system's application.
Thus a biometric system is essentially a pattern recognition system, which makes a personal identification by determining the authenticity of a specific physiological or behavioural characteristic possessed by the user. An important issue in designing a practical system is to determine how an individual is identified. Depending on the context, a biometric system can be either a verification (authentication) system or an identification system.
Point-to-point (PTP) RF data networking refers to the use of wireless (RF) technologies to create a data link between two … exactly two … locations. PTP wireless data networks tend to require high data throughput over long distances.
PTP is different from point-to-multipoint (PMP) in two key ways. First, PMP has more than two locations. Second, because there are more than two locations all sharing the same access media (the RF channel), the control and use of the RF channel becomes more complex
Even within the "unlicensed" RF spectrum there are still regulatory requirements placed on the RF equipment. These regulatory requirements are typically different for PTP products than for PMP (sometimes very different). Most typically, these regulatory requirements deal with limiting the strength of the RF transmission. Just to make things more complicated, these restrictions are often placed on the RF equipment itself (TX power) and also on the combined affect of the RF equipment and the RF antenna (EIRP). PTP regulatory limits are typically higher than those for PMP products.
Wireless PTP data links typically do not require much in the way of network services. As a result, PTP devices typically operate as simple (Ethernet) bridges and leave services such as routing and traffic policing to the networks they are connecting. In a sense, a PTP wireless link becomes an invisible "cable" joining two data network devices. Without wireless technology, distances of over 100 meters typically must be served by wide area network (WAN) technologies such as T1/E1 and fiber. However, wireless data networking allows for local area network (LAN) technologies such as 10-BaseT to be used. These
