The application and development trend of fisheye panoramic camera

Fisheye panoramic camera as a new product, its special structure and unique without blind area monitoring feature, brought a totally different new experience for security monitoring. Especially in nearly a year or two, with the popularity of HD network and the fisheye technology mature, fisheye camera for panoramic monitor, is favored by users in the field of civil, commercial, police or special, and began to gradually obtained the practical application in the field of various industries.

The most core technology development of Fisheye panoramic camera is the optimization of the fisheye image correction algorithm. The fisheye image correction is to correct the serious deformation images information provided by the fisheye lens , to meet the visual habit projection image.

Wodsee fisheye panoramic camera(see below picture) is exquisite and fashion on exterior design, intermediate for panoramic fisheye lens, around the small window are more groups of dot-matrix infrared lamp, infrared distance can reach 10 meters.

FAQ: 

1. How to install Network video surveillance system front-end equipment?

Network video surveillance system system front-end equipment installation needs to be specific for different equipment, in the installation before carefully read the product manual and installation requirements. The standard steps for installing the terminal device are as follows:

1) Unpacking confirm the completeness of the equipment listed in the product description.

2) Check the power supply voltage to prevent the equipment does not match the equipment damage.

3) to confirm whether the equipment working environment in line with the product manual on the equipment operating temperature, power and other environmental

begging.

4)control equipment manual power test, to confirm a variety of working status indicator to normal operation

2. How to choose a infrared camera?

Infrared camera is mainly used for the target needs day and night surveillance, with special emphasis on the need to monitor the night, and the target environment is not too strong light scene conditions. The specific choice based mainly on the camera and the target before the distance, the general distance of the infrared camera range of 20-100 meters, the farther away from the price the more expensive, while power consumption is also large.

In addition, the choice of infrared camera should consider the infrared light power switch control problems. This problem can be used both manual and automatic control.

3. What are the current mainstream storage technology?

1) Universal storage, the traditional storage technology is DAS, is the storage device directly connected with the server, completely to

Server-centric, as part of the server. Storage devices for DAS can be tape, disk, disk display, and tape libraries. Typical DAS storage devices are all kinds of disk displays.

The current network storage technology is NAS, SAN, ISCSI. NAS is based on the TCP / IP protocol to provide file storage services; SAN is mainly based on Fiber Channel, data-oriented storage, can be seen as a traditional bus expansion; ISCSI is in the previous two technologies in the TCP / IP network On the convergence of the data block by the SCSI protocol package in the TCP / IP packet in the TCP / IP network transmission technology.

The characteristics of a variety of storage technology analysis and introduction:

The storage area network SANs used to store data has been built on Fiber Channel (FC

Fibre-Clannel technology, this technology provides a high-performance block data access scheme for storage domain applications. Due to the application of IP over LAN and WAN and good technical support, it can realize long-distance block-level storage in IP network, and replace IP channel protocol with IP protocol to form IP-based SAN storage. With low cost, cost-effective, free from distance restrictions, not easy to form information islands and other characteristics, IPSAN has been more and more attention and application. Commonly used several storage methods As the early network is very simple, direct-attached storage (DAS) is the first to be used in the network storage system. In the DAS storage architecture, in order to avoid a single point of error, usually use a number of servers to share a storage system. When you need to increase the system's storage capacity, the general use of increased disk display (RAID) way. DAS was once a popular storage system, but can not meet the large-capacity storage needs, so there have been NAS and SAN and other storage technologies. The network storage system includes the file server and the storage device component, the NAS installs the preconfigured storage device, causes the master server to "free" from the file I / O operation, depending on the server as an optimized file system, the operating system no longer To achieve the calculation function, only to provide file system functions, the client directly through the NAS system and storage devices to exchange data between. NAS directly run the file system, such as NFS / CIFS, etc., by setting up the NAS can be achieved in different clients (such as NT and Unix) to share data between. Drive, tape drive or removable storage media and embedded system software, it can support a variety of application protocols (such as NFS, CIFS, FTP, HTTP, etc.), but also to support a variety of operating systems, such as Unix / windowsNT, and In the use of different network environments do not need to make any changes to the network environment. NAS products directly through the network interface to connect to the network, simply configure the IP address, you can be shared by users on the network. NAS is suitable for transferring files and sharing files over a LAN. This approach will take up a large number of host CPU resources, file operations delay is quite large. The increase in the amount of data, so that DAS and NAS the same problem, not to improve the storage capacity and unlimited increase in storage devices.

Compared with DAS and NAS storage, SAN's advantage is that all data processing is not done by the server, SAN is a storage device, connected devices and interfaces integrated in a high-speed network technology, which itself is a storage network , Assume the main network of data storage tasks. In the SAN network, all data transmission in high-speed, high-bandwidth network, SAN storage is the realization of the physical hardware block-level storage access, improve the storage performance and upgrade capabilities. According to the transmission protocol and physical medium adopted by the storage network, SAN is implemented by FCSAN and IPSAN. FCSAN adopts high-speed fiber channel to form storage network. It is the mainstream technology of SAN. With the openness of Ethernet and IP and the advantages of block storage in many ways, and IP protocol-iSCSI instead of Fiber Channel protocol to achieve end-to-end SAN storage. ISCSI technology requires only low-cost investment, you can easily and quickly on the information and data for interactive transmission and management. Compared with the previous network access storage, iSCSI to solve the openness, capacity, transmission speed, compatibility, security and other issues, its superior performance so that the date of its release by the market attention and favor.

2) NVR high-definition network dedicated storage

Can be used with the network camera (IPCamera), based on IP network monitoring signal access, distribution, browsing, video, playback, management and other integrated features.
