Sensitivity Camera Problem
When the camera when ingested brighter scenes, the picture displayed on the monitor usually bright, in addition to the light sensitivity of the camera are also important factors affect the resolution.
Camera sensitivity CCD (CMOS) to ambient light sensitivity, or a normal CCD imaging of the dimmest light required. The unit is lux illumination (Lux), the smaller the value, expressed the need for the less light, the more sensitive the camera. Moonlight level (about 0.1Lux) and Starlight pole (0.01Lux or less) high-sensitivity cameras can work in very dark conditions, 2 ~ 3Lux a general illumination.
When we buy the camera first take into account our environment, and then select the sensitivity depending on the environment of different products.
Definition Camera Index
Clarity index is a parameter of the camera to see the product brochure first time I will be concerned. In a sense, clarity index of the camera determines the grade.
The market most analog products with a more than 500 lines of horizontal resolution, the product is part of 960H program has reached the level of 700 lines. Pixel digital camera is more of a level of performance which can achieve the level of clarity, such as the 1.3 million pixels and 200 million pixels, roughly corresponding to 700TVL and 1000TVL. But the case of individual businesses or sweeping vacuity also exist. If analog cameras monogram Horizontal resolution 540TVL, pay attention will find that there are lines of small print behind the “center-definition.”
Limited to the lens of the camera itself, factors CCDDSP programs, and some cameras can only be close to the center of the image showing the location of the highest resolution, but at the edge portion can not achieve this clarity, the overall average resolution might only 520TVL, even more low. Therefore, the need for additional attention to be selected.
1. Can several users view one site at once?
Most Internet-enabled Security DVR systems allow multiple users to view the same site simultaneously.
However, as more people look at the same cameras/DVR at the same time, the bandwidth will be shared between them.
2. WHAT’S THE OSD MENU FOR SECURITY CAMERA ?
OSD means on-sreen display, it’s a menu system for TV, Monitor…etc.
Using the OSD menu, people can adjust various of settings of security camera including exposure, white balance, back light compensation, day & night selection, , Motion, privacy…etc.
3. What are the advantages of network video surveillance systems compared to analog closed systems?
The information flow and the media flow of the network video monitoring system are digital and independent of each other. The hardware and software adopt standardized, modular and large-scale design concept. The configuration of the system equipment is versatile, open and flexible, Control functions, easy data processing, easy to use and system installation, commissioning and maintenance of the advantages of simplicity. At the same time, IP, the scale of digital products will bring cost advantages.
4.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.
