In addition to remote monitoring via the Internet in any corner of the world, IP Camera can effectively reduce costs through network monitoring. Its "plug and play" function does not have to be installed like an analog camera. Coaxial cable. As long as the existing network can be used, this is the advantage of the IP Camera.
The following analysis and comparison are conducted in four aspects: monitoring room, program comparison, investment analysis, and IP Camera (webcam) application trend.
First, the monitoring room
monitoring room
1, reliability: The main equipment IP Camera (network camera) uses an embedded real-time operating system, the required equipment is simple, and the image transmission is achieved through the integrated wiring network, the system reliability is quite high;
2, the cost performance ratio: the required equipment is extremely simple, the system control by the back-end software system, eliminating the need for a large number of traditional analog monitoring system equipment, such as expensive matrix, picture splitter, switch, video to the network Host and so on. As the image transmission through the integrated wiring network, eliminating the large number of video coaxial cable, reducing costs;
3, security: The system has set different levels of user rights, only the highest level of authority of the user can set or change the entire system, the user does not have permission to receive images. In addition, the storage of image data is a proprietary format;
4, use and maintenance: The installation of the system is extremely simple, the installation and use of the software system is also very easy to understand. In terms of maintenance, the wiring of the system is very simple, and the reliability of the main equipment is high, the maintenance performance is good, and remote maintenance can be realized;
5. Extension and Extensibility: When it is necessary to add monitoring points and monitor the host, it is only necessary to add a camera or PC through the existing network, and there is no need to make any changes to the existing wiring system;
6, a wide range of applications: regional monitoring, the use of the network to transfer real-time images, such as offices, buildings, etc.; cross-regional remote monitoring, chain business, large factory room, remote elderly, child care, public buildings, no one environmental monitoring, Financial institution branch monitoring, traffic supervision, false alarm identification, etc.
Second, the program comparison
1. Compared with the traditional closed-record television monitoring system, IP Camera (network camera) monitoring system does not require coaxial cable, no large video distributor; software to achieve NxN many to many (ie, multiple observers can see multiple shots at the same time ); Installation requires less equipment, the project cost is greatly reduced (the entire installation process is to set up the camera and install the system management software on the PC), greatly reducing the wire; make full use of network resources, use broadband network image transmission is very cheap, and enhance the monitoring range The flexibility can be achieved directly remote monitoring, using network update software. These are incomparable with traditional closed-record television systems.
2. Compared with the current monitoring system, the IP Camera (network camera) monitoring system has a reduced range of requirements for the PC, and it can be generally configured; no software maintenance is required; the equipment room can be installed in aisle and poor environment; it can be avoided. Deadlocks and defects that can't be monitored while rebooting. These are unmatched by PC-based digital surveillance systems. (Xinrongquan video monitoring software.cn)
Third, investment analysis
Based on the IP Camera (network camera) monitoring system and transmission monitoring system costs need to consider many factors. The main factors include the number of monitoring points, the number of monitoring sub-controls, the monitoring range, the recording range, the video requirements, and the alarm requirements.
When comparing the cost of IP Camera (network camera)-based surveillance systems and traditional surveillance systems, there is also an important starting point. Is network cabling and computers included in the cost? The reason for including the cost is simple; the reason for not including the cost is that the network cabling and the computer are already existing investments, and monitoring is also required.
In a building, when the number of monitoring points reaches 50 and the number of monitoring vices is 10, the investment of the two schemes is similar (350,000). It can be seen that as the number of monitoring points of the system increases, the investment on the IP Camera (IP Camera) and the traditional monitoring system becomes closer and closer, and eventually the investment on the traditional monitoring system will exceed the IP Camera (Network Camera).
Fourth, IP Camera (network camera) application trends
After the maturity of Ethernet technology, the broadband information network extends the Ethernet port to the entire building. In addition to providing high-speed network access, it can also replace copper-axis cable image transmission lines and incorporate real-time image monitoring into broadband information network applications. Making information networks replace traditional closed-record televisions has become inevitable.
With the increasing maturity of digital video compression coding technology, the popularity of microcomputers has created conditions for PC-based multimedia monitoring. PC-based multimedia monitoring system has strong functions, but it mainly solves the problem of small-scale monitoring. When the transmission distance is far away or Internet access is required, PC-based multimedia monitoring is not good enough in stability, high in power consumption, needs to be attended, and the openness of software is not good. This provides a stage for network video surveillance based on network and embedded technology.
IP Camera integrates ordinary cameras and network converters to convert images into TCP/IP network-based data packets. The pictures taken by the camera are transmitted directly to the network through the RJ-45 Ethernet interface. Can monitor the screen remotely.
Currently, there is a common phenomenon in the IP Camera on the market. Different network operators have slow access to each other and cannot even perform remote viewing. For example, the telecom users' IP cameras are viewed through Netcom. Smooth or unable to view. Telecommunications users IP Camera (network camera) view through 3G, can not view.
For this reason, P2P penetration technology has been added to the original TPC/IP transmission mode, making it possible for telecommunications, China Netcom, and 3G to communicate with each other smoothly, thus achieving the ideal goal of interoperability between the Internet.
IP Camera adopts the most advanced camera technology and network technology, as well as powerful functions such as PTZ, wireless WIFI, infrared night vision, IR-CUT dual filter, P2P (point to point). Built-in system software enables true plug-and-play, freeing users from complex network configuration; built-in large-capacity memory to store images before alarm triggering; built-in I/O ports and communication ports facilitate external peripheral expansion Such as: access control systems, infrared sensors and other devices.
In response to the national environmental protection low-carbon call, IP Camera (network camera) power adopts the latest energy-saving technology.
