The difference between ip monitoring system and analog system

Network surveillance camera (http://ipc.joveblog.com) is what we often call network camera IPC, which is different from our previous analog surveillance camera.

The differences between network cameras and analog cameras are: (1) clarity (2) transmission mode (3) technical requirements. Their meanings are: clarity: the most basic network camera is now 1 million images, the commonly used is 2 million images, and the more advanced ones are 5 million images.

The compression format is different. The format of the two video compression is also different. The most important thing is that the webcam is mainly a camera, but the analog camera is not allowed. Some high-end monitoring systems mostly use webcams.

What is the system IP

ip is the address of your computer on the network, that is, the house number. Only with this address can you surf the Internet, no Then you can't access it. The IP of each Internet computer in the network is different. If you are a broadband dial-up Internet, the IP of each Internet is also different. That is, the network automatically assigns you an IP address.

The IP protocol defines five 32-bit addresses for each computer on the Internet, called IP protocol addresses, or IP addresses for short.

The so-called IP address is a 32-bit address assigned to each host connected to the Internet.

IP is the abbreviation of Internet Protocol, which is one of the basic protocols of the Internet. Computer IP refers to the unique identification code assigned to a computer. It can help the network correctly send information to a specific computer when exchanging information, so it is an important basis for network communication.

Interpretation: the protocol of interconnection between networks. Grammar: IP, the full name of the Internet Protocol address, refers to the IP address, which means the digital label of the Internet protocol device assigned to the user for surfing the Internet.

How to set the IP address and gateway address of the win7 system

First, click "Network" on the win7 desktop. Select "Change Adapter Configuration" in "Network and Sharing Center".Right-click on the local connection and select "Properties". Enter the properties page and click "Share" and check "Allow others to share Internet connections".

Open the "Control Panel", set the "Viewing Method" to "Small Icon", and then find and click "Internet Options". Click "Change Adapter Settings" in the open window. In the open window, right-click "Local Connection" and select "Properties" in the pop-up menu.

The steps to set the IP address, subnet mask and gateway are as follows: open the "Network and Sharing Center" of the computer, find the connected network, take the local connection as an example, and click the "Local Connection" option. After entering the "Local Connection" option, find the "Properties" option.

Opening "In the Internet Protocol Version (TCP/IPv4) properties window, check "Use the following IP address", then enter the IP address and subnet mask, enter the default gateway address in the default gateway input box, and finally click "OK" to complete the setting. Test gateway.

The local IP address is generally in the local area network, such as our common routers and switches and other network environments often need to set up local connection IP.

If the computer encounters a network problem, it will generally set an IP address to solve the problem. A user feedbacks that the win7 system encounters a problem of filling in a default gateway when setting the IP address. Of course, this should be filled in according to the actual situation of the user's network.

What is IP broadcasting system

1. First of all, IP broadcasting system is a broadcasting system based on Internet technology, which can transmit audio signals through the network to achieve large-scale and long-distance broadcasting coverage. Within the city, weather information and traffic status notifications can be transmitted to various areas in real time through the IP broadcasting system to provide timely and accurate information services for citizens.

2. The IP network broadcasting system is a product that is completely different from the traditional broadcasting system, FM addressing broadcasting system and CNC broadcasting system.

3. Campus network (digital) IP network broadcasting system [1], that is, dtsaic network broadcasting system, Shenzhen Liwanzhao Electronic Technology Co., Ltd. IP network broadcasting transmits traditional broadcastingThe signal becomes a digital signal, so that it can be transmitted to any place needed through the Internet or LAN, breaking through the distance limit.

What is the campus network ip broadcasting system

The digital network broadcasting system is an intelligent broadcasting system developed by Wankai for the currently widely used TCP/IP network. The system uses network technology to transmit the audio signal in the form of IP packets on the local area network.

Campus network (digital) IP network broadcasting system is dtsaic network broadcasting system. Simply put, it is to transmit various audio files through the network to realize the broadcast system from control to playback.

IP networkThe broadcasting system is a completely different product from the traditional broadcasting system, FM addressing broadcasting system and CNC broadcasting system.

The digital IP network broadcasting system is an important embodiment of the multimedia form of network communication and an important embodiment of the online development of radio and television media. For traditional broadcasting, network broadcasting is a supplement to its functions, and the two are complementary and cooperative.

Timed broadcasting system: It is mainly used for inter-class ringtones, eye care exercises, electronic alarm clocks and other functional broadcasts to each sub-district of the campus. Emergency broadcasting system: When there is an emergency, such as fire, major accident, power outage, etc., the broadcasting studio can make emergency broadcast to the whole hospital with one click.

Multimedia communication: The IP network broadcasting system can transmit alerts and notification information to various areas and devices on campus through a variety of media forms (such as voice, text, pictures and videos).This information can be transmitted to designated terminal devices through the network, such as computers, mobile phones, TVs, broadcasting systems, etc.

What does fire system IP mean

1. IP (International Protection) protection level system is made by IEC (International El Drafted by ectro Technical Commission. Lamps are graded according to their characteristics of dustproof, foreign intrusion prevention, waterproof and moistureproof.

2. IP refers to the protection level of the shell of electrical equipment 1: P54 refers to the dustproof level of the shell to completely prevent the intrusion of external objects, although it cannot completely prevent dustDust enters, but the amount of dust invading will not affect the normal operation of the lamp. The waterproof level is to prevent the intrusion of splashing water, that is, to prevent water splashing in various directions from entering the lamp and causing damage.

3. IP means protection level. The first 3: Prevent the intrusion of solid foreign objects with a diameter of more than 5mm. Prevent tools, wires and similar small external objects with a diameter or thickness of more than 5mm from intrusion and contact with parts inside electrical appliances. The second 0 0 has no protection. There is no special protection against water or moisture.

4, IP44 is the dustproof level of this device is 4 (prevent the intrusion of objects larger than 0mm, prevent the intrusion of mosquitoes, flies, insects or objects with a diameter of greater than 0mm) and the waterproof level is also 4 (prevent the intrusion of splashing water from all directions).

5. IP refers to the Internet protocol address, also known as the Internet protocol address. This IP address is unique and can only be connected to the Internet if the IP protocol is followed.

6. The IP protection level system is to grade electrical appliances according to their dustproof and moisture-proof characteristics. The IP protection level is composed of two numbers. The first number indicates the level of dustproof and foreign objects to prevent the intrusion of electrical appliances. (The external objects referred to here include tools, and human fingers should not touch the charged part of the electrical appliances to avoid electric shock.
