FAST Swift router's high-definition video transmission Transmission Prospect Analysis

At present, there are several mature technologies for wireless high-definition transmission, which are low-latency WHDI technology, high-bandwidth WirelessHD technology, Intel's WiDi technology, WiGig technology with many alliances, and DLNA technology with barely a few. . The full name of WHDI is "Wireless Home Digital Interface", that is, wireless home digital interface.

FAST routers have strong processing power and high-speed data transmission speed, which can meet the needs of high-speed networks and are suitable for games, high-definition videos, large file transmission and other needs. The functions of TPLink router are simplified, and there is a lack of advanced functions and personalized customization options.

Realize network connection. At the same time, while ensuring a smooth network connection, Swift router can also provide a certain degree of security protection to protect users' privacy and data security.

bitstar recorder initial password

1. In general, the 8-digit initial password of the driving recorder is 12345678. If it is 10 digits, it may be 1234567890, driving record The initial password of the instrument can be found in the manual.If you forget it after changing the password, you can enter the initial password to connect by restoring the factory settings.

2. The 8-digit initial password of the driving recorder and the locomotive interconnection is generally 12345678.

3. At present, the 8-digit initial password of the driving recorder on the market is generally "12345678" or "000000000". The initial password of different manufacturers will be different. The specific situation should be based on the instructions of their respective products. If necessary, you can ask the manufacturer.

4,", of course, and the initial password is not necessarily like this. In fact, it may be based on the instructions for use on the driving recorder. If you really can't find the instructions for use, you can also learn about the online customer service of the store when buying the driving recorder.

System introduction of wireless microwave mobile video transmission system

Portable image transmission system: The device can also be placed in a hidden part of the human body for hidden transmission. It is mainly used for technical reconnaissance and forensics of public security and security inspection departments.

The system adopts DVB-T standard, COFDM modulation technology, and digital image compression MPEG2 technology. DVB-T has been proven to have outstanding performance in fixed, mobile, portable reception, etc.

Microwave transmission Microwave transmission is the most flexible and adaptable communication means, with the characteristics of fast construction, small investment and flexible application. Microwave transmission is not only widely used in mobile networks, but also favored by fixed network operators;It has a wide range of applications and can be used in radio and television, security video monitoring transmission, control, etc.

One of its mainstream applications is the convenient and flexible wireless real-time video surveillance system, such as wireless home anti-theft, car surveillance, etc. Mobile video surveillance based on a variety of wireless transmission means has become a new development direction for video surveillance with its unique flexibility. Wireless video surveillance includes two aspects: one is the movement of the monitoring center.

· Qos guarantee of wireless video In mobile communication, the Qos guarantee of wireless video is very complex due to the user's movement. It can be seen that there is a sharp contradiction between the need for transmission of video signals and the characteristics of the wireless environment, so wireless video transmission faces great challenges.

In the video return of the transmission line in the uninhabited areaUnder the scenario of transmission as the main business needs, the wireless technology of the Internet of Things with narrowband and short-range transmission is not applicable to this scenario. At present, the mainstream wireless video surveillance technologies include WLAN (wireless LAN), analog microwave modulation technology, 4G/5G mobile Internet of Things technology, and satellite communication technology.
