Home is a warm place, dirty and should not be disturbed by outsiders. Stolen home, who are angry Fameng encounter. After all, stolen thing, if someone does not want to happen. Home Security is a very complicated matter, as long as the security know-how to understand a little bit, we can at the base. Such prevention is the most scientific and efficient? “Exterior doors, security doors, security doors ……” The market is open to all kinds of “door” Are you ready to buy security doors for future owners are very confused, security doors really so many different names? Within the industry against the author, name of security, the door is clearly defined, and the safety of the door, and the reports of consumer complaints, and so on, and there was a clear difference between ordinary products. Product calculations for anti-theft door “entrance doors, security doors, security, security door, steel door see ……” If you go to the market to buy the security doors, should be familiar with these terms. Yucai Yang Xian Ji Fangban researchers said that since October 1, 2007 and beyond, China has formulated and implemented a new national standard GB17565-2007 “anti-theft security doors GM technology conditions.” The new national standard in accordance with the length of the tamper, plate thickness, and other indicators of anti-theft security door security product classification, anti-theft security level, “”, “B”, “C”, ” D “4, to four levels of locking points at least 12 of those 10, 8 and 6″, “the highest level of security,” D “grade to a minimum. Regardless of the level of security doors to the use of electric drills, pry bars and other tools to the weak parts of the destructive tests, must meet more than 6 minutes will not be opened. Anti-theft door Lay Say, “even though the new standard for the standard, it is still difficult to avoid bad things to play” side of the ball. “As long as he is not the name of security doors, then use any standard door, he could not do. ‘S Recommendations to consumers when they deliberately confusing the concept of selling the concept of security doors. A brand name on the invoice column, no anti-theft doors and other written security door or doors, so to write., the time of purchase, consumers will depend on whether the bill is ready for the security doors. “inspection reports are only valid for two years, even when the door industry, “3C” certification is still voluntary, but a valid security doors should have the following characteristics: door manufacturer are sent on a qualified certificate, hit a permanent seal on the product-level identification, but also consumers with “type lock type of test and inspection reports and products to the local public security organs the record books.” Yang said Yucai, security doors and other products have inspection reports and the current door industry in China has seven units in the country an audit report, including Shanghai, Xian, Beijing, Chengdu, Shenyang, Wuhan and Guangzhou, but a few have the right to an inspection report to give. At the same time a test form is divided into three groups, namely the Commission’s own audit, the closure of the local public security organs samples of the type of inspection for quality control departments, random spot checks, but can only type of test a valid certificate of suitability of the security doors. And the inspection valid for two years, expired, expires. Security door home security for consumers that their products are more complaints than conventional products, the channel through which consumers can Consumers Association, the industry complaints, you can do to the Public Security Bureau Technology, a complaint, more consumer protection measures .

Today we see more and more enterprise for the entire cost, improve productivity and to begin or already in place

Video Conference System . Therefore, IT departments must consider the times of network congestion MeetingPlace video quality can be guaranteed, companies need to dedicated networks to build for video conferencing, and does not deteriorate the performance and reliability point of departure, the acquisition includes video conferencing and data transmission.

In view of video conferencing applications are fully completed, the companies first WAN application traffic to a better understanding of the whole. Cause of the network administrator can clearly determine whether the company videoconferencing network traffic, and when WAN bandwidth is insufficient, it is necessary for the network bandwidth to upgrade to performance problems. If the network administrator has a clear understanding of the application of the volume occupied bandwidth, wide area network optimization of video conferencing over the need for bandwidth, transport and application-level flow of the percentage of each to spend. They have important applications can be separated from the power, control and management applications where other non-essential traffic, or video conferencing is to improve the quality of service is based on an appropriate increase bandwidth to the needs of the business to meet .

In traditional routers at the edge of the network management, MPLS (Multiprotocol Label Switching) is

Monitor the implementation of LAN traffic and will provide the necessary traffic control has some limitations and may lead to critical network edge video conferencing and data transmission congestion point. But this does not, a good application delivery

MPLS technology should be able to treat their own equipment, or a combination of edge routers, for video conferencing and data application traffic is used by adding a appropriate way to celebrate in advance people on the edge of the network traffic optimization. Let the constraints MPLS network management personnel of the technology to video-conferencing and data to optimize the congestion several times to service level agreements (SLAs SLA) targets a minimum. At the same time an application distribution

Solutions must also be able to make intelligent compression technology to help, depending on the type of traffic is compressed data applications, allowing companies to reduce the bandwidth usage and ensure that those who need a high-quality video images of traffic to ensure the sound is not compressed.

As video conferencing to improve the quality and cost of the highlights to improve video conferencing highly distributed enterprises of all ages. However, between the LAN and WAN connections, the network was cause congestion and affect the quality of the main meeting. When we have the bandwidth and access to all applications defined, and the visibility was considered in the further delay, delay jitter and packet loss can seriously affect the quality of the meeting of these three problems.

video conferencing, especially in two-way session, the delay results in a decrease in the user experience. But the only video conferencing, data packets on the network while waiting for a higher priority than other traffic to get is not enough, because it is a busy highway, do not be the first location can be delivered quickly . Really should do a more rigorous and intelligent video-conference with all relevant class to ensure that each type of traffic lane to the right to demonstrate.

compared to the delay, and delay of oral communication in the conflict, delay jitter, video-conferencing for each data packet transmission, encountered various unexpected delays caused by. Usually covered with a jitter buffer, or temporarily stored, then “softened” the audio and video data packets, jitter is more than 100ms is required, making the problem worse. If, based on the traditional by adding intelligence and policy-based bandwidth management policy, data and voice and video traffic is shared and to a certain speed and quality to maintain, so this problem can be solved.

Videoconferencing is often faced with packet loss, packet loss was equal to or greater than 3%, meet the public clearly felt that the meeting will be on the side or even declined. The best way around this problem is the intelligent control of IP networks, wide area network is available in the IP joint road congestion and unpredictability a minimum, the performance of applications to maximize, leading to an unprecedented flow of control and performance optimization.

In addition, video conferencing always impact on the network and application performance, because of the different protocols used in network operations, a different, more interactive applications, an arbitrary data types and more difficult to predict in advance the bandwidth required. More and more companies begin to hope for intelligent solutions, application delivery technology of visibility, control and acceleration without doubt a strong intelligence support.

In short, an excellent application delivery solutions for video conferencing applications, a good solution to network congestion and delay, jitter and packet loss problems, you should avoid crossing the LAN and WAN quality the video-conference loss.

the SIL Security

Private Security Industry is one of the fastest growing industry in the United States, public panic over crime of September 11 days after the incident and the increasing number of criminals and militants groups around the world helped this industry in booming more in less time. Currently Private Security Industry has more money and hiring more guards than public police across the country.

According to the estimates and economic studies, the total cost of the private security was around one billion, billion, compared with the cost of the public police in 1990. There were more than 10,000 private security companies engaged in private security, and they employ some 1.5 million guards, which is almost three times and the 554 000 state and local police. This industry, which collects billions in profit are growing rapidly. It was estimated that the number of private security guards will provide services to two million by 2000.

private security guards employed by private security is everywhere, patrolling shopping malls, workplaces, apartment buildings and neighborhoods. The rapid growth of large private shopping centers, and even shrinking the public streets and the change in shopping trends are also helping the people factor in the growth and flowering of these private security services. Even the government is taking the services of private security companies to ensure the safety of a busy public places such as New York’s Grand Central Station to insure. Many municipalities are planning to cut operating costs further by hiring a private security people to work with ambulance services, parking enforcement and crime scenes and transport prisoners guard.

urbanization, modernization and the value of the United States also need to encourage permanent protection. Board of Directors of the police system was not enough for this huge demand for security personnel and armed personnel should, resulted in a growing and hiring guards helped the Security office to earn more income. The case was not the only application of its governmental or private organizations, and places to visit in the evening. Intelligence services to several requests and questions about the protection of private property and individuals make. Many wealthy people started the services of private security agencies and security guards employed by them in their permanent safety and the protection of their own lives.

In short, it was the beginning of a new era in the history of Homeland Security in the United States. The trend for private security guards are becoming increasingly popular, providing a better service for employment and earning opportunities for military veterans, which offer the opportunity to make their own bread and butter money.
