Network camera monitoring system advantages and application trends analysis

Network camera monitoring system advantages

The need for centralized management and remote monitoring, network camera is the only choice!

Centralized management is an international airport, for example, a 600 point system, if using the traditional analog CCTV system is difficult to control; distance refers to the range of more than 50 km of the system, if using the traditional analog CCTV systems, such as fibre, etc., will cause costs to unacceptable.

Webcams in addition to any corner of the world through the Internet for remote monitoring, network monitor can also be effective in reducing costs, it's "plug and play" feature is not the same as the analog video camera must install coaxial cable.

As long as the use of the existing network will be ready to use, these are the advantages of the network camera.

System advantages

Based on a network camera system has the following advantages:

Advanced: use existing cabling network transmission of images, for real-time monitoring system of the front-end device is required, the connection is simple, back-end just a set of software systems;

Reliability: main equipment network camera using the embedded real-time operating system, required equipment, but the image transmission via cabling network implementation, system reliability is high;

Price-performance: the device is extremely simple, the system of control by the back-end software systems, eliminating the traditional analog surveillance system in a large number of devices, such as expensive matrix, screen divider, switches, video transfer network hosts, etc.

Because the image of the transport network via cabling, saves a lot of video coaxial cable, reducing costs;

Security: System set up different levels of user permissions, only the most advanced permissions can be set for the entire system or change, no access, user is not receive images.

In addition, image data storage is a proprietary format;

Use and maintenance: System installation is extremely simple, software installation and use of the system is also very easy to understand.

During the maintainability, system wiring is very simple, and the main equipment reliability is high, the maintenance of good performance, and can realize remote maintenance;

Extensions and extensibility: when the need for increased monitoring and monitoring host, just add a via existing network or PC cameras, and do not need the existing wiring systems do modifications;

Application range: regional monitoring, using the Internet to transmit live images, such as offices, buildings, etc.; spanned remote monitoring, chain business, large factory machine room, distal man, child care, public buildings, unmanned environment monitoring, financial institutions branch monitoring, traffic monitoring, error alert identification, etc.

Comparison with other programmes

Relative to the traditional closing were recorded for television supervisory system: network camera monitoring system need not be coaxial cable, without huge video distributor; and software implementation NxN many-to-many (that is, multiple observers may also see more footage); install the necessary equipment, engineering cost significantly lower (the entire installation process is to set up the camera and on PC installation system management software) and significantly reduces wire; full use of network resources, broadband network image transmission is very cheap, enhanced the monitoring range of flexibility to directly implement remote monitoring, using the Internet to update the software.

These are the traditional closed recorded TV system.

Relative to the current supervisory system: network camera monitoring system on the PC requirements to reduce the scope, General configuration; no software maintenance; no room, you can install the difference in the hallway and the environment; you can avoid the panic is like and restarts causing defects cannot be monitored.

These are PC-based digital monitoring system.

Investment analysis

Based on network camera monitoring system and transmission monitoring system cost comparison you need to consider many factors.

The main factors are monitoring points, control the number of Deputy accused, monitoring range, video, video calls, alarm calls, etc.

In the comparison based on network camera monitoring system and a traditional monitoring system cost, there is another important point: If the network cabling and computer cost? the cost of the reason is simple; not included in the cost of ground network cabling and computer is already have investment, not monitoring needs.

In a building, when monitoring points reaches 50, monitor the number of Deputy accused to 10, the two programmes of investment are similar (35 000).

You can see, with the system of monitoring and control points of the increase, a webcam and a traditional monitoring system on the investment is getting close to final legacy monitoring system investments will exceed the network camera.

Webcam application trends

Ethernet technology is mature, broadband information network Ethernet network port extends to the whole building, in addition to providing high-speed Internet access, you can replace copper shaft cable image transmission line, the real-time image control into broadband information network application range, which makes information network instead of the traditional closed recorded TV became inevitable.

As digital video compression technology matures, the popularization of microcomputer for PC-based multimedia monitor.

PC-based multimedia surveillance system capabilities and strong, but mainly solved the problems of small-scale monitoring. When the transmission distance or Internet access, PC-based multimedia monitor stability is not good, power consumption and high, need someone on duty, the openness of software. This is based on the network and embedded technology network video monitoring provides the stage.

Webcam integration ordinary cameras and network converter, converting images to standard based on TCP/IP networks, so that the camera of packet the picture via RJ-45 Ethernet interfaces delivered directly to the network, through the network to remote monitor screen.

Network camera adopts first

The camera technology and network technology, with powerful features. Built-in system software can achieve true plug-and-play, enabling users to save a complex network configuration; the built-in large capacity memory can store the image before the alert is triggered; built-in I/O port and the communication port for easy expansion of external peripheral equipment such as access control systems, infrared sensors, tilt; also provided software package (SDK) make it easy for users to quickly develop application software.
