4G monitoring
When 4G just appeared in people's lives, there was a paragraph on the Internet. If your mobile phone forgot to turn off 4G traffic, the next day when you wake up, your house is estimated to be the operator. Of course, this is just a joke, but what I want to express is the problem of high-speed traffic at my own expense. Now operators have introduced a lot of 4G cards in unlimited quantities, but after actually reaching a certain amount of traffic, the network will automatically slow down. For 4G wireless monitoring that is transmitting 24 hours a day, that traffic is also a lot of money. In particular, the era of 5G is gradually being introduced, the upgrade of high-definition surveillance, and the video traffic generated by all-weather monitoring is also a key issue.
Wireless bridge networking
The wireless bridge realizes communication through the self-built network, and does not need to borrow the carrier network. At present, wireless bridge technology is rapidly developing, and system stability and rate bandwidth can support high bandwidth transmission requirements. At the same time, point-to-point/point-to-multipoint networking can be realized. According to different functions, the wireless bridge can realize signal data transmission under the condition of viewing from 1 to 100 kilometers or more. If you set up a back-to-back network transmission method, the transmission distance will extend further.
WFI system
It is based on the data transmission under the 802.11 protocol. Since WIFI uses the traditional 2.4G channel transmission, in the case of widely used WIFI, the same frequency interference is more, which will reduce the communication efficiency and distance. At the same time, the WIFI RF power is low, and the transmission distance is limited. Generally, it is suitable for communication in the lower range of the home or the store.
Summarize the traditional wireless video transmission technology, in addition to a few other, in some special industries, such as emergency command and rescue, and other departments to deal with the scene of the incident without wired network and carrier network access to transmit video and data to achieve command and dispatch In such scenario applications, it is very practical to establish a data link transmission signal over a satellite network. However, the cost of renting satellites is based on bandwidth charges. Signals for transmitting high-bandwidth resources such as video are expensive at their own expense, so satellite communications are not considered in conventional monitoring systems. Four: Traditional wireless video surveillance applications have a wide range of applications, whether indoors or outdoors, if the transmission conditions are accessible to the accessibility environment, wireless network transmission and wireless transmission can be achieved. Laian Technology's ten years of industry experience, from product development to production, wireless transmission solution design and planning, technical support, etc. can provide a series of support for customers.
Waterjet Cutting sand, abrasive sand, Garnet Sand used for waterjet cutting of stainless steel, aluminum, carbon steel plate, copper, titanium alloy and other metal materials, tile, stone, rubber, glass, wood Wait. Special application glass cutting, mobile phone screens, semiconductors, etc.
High quality waterjet garnet sand usually has the following characteristics for your reference:
1. High quality garnet sand for waterjet cutting usually has a fast cutting speed and a more strait and smoother cutting surface;
2.The high quality garnet water cutting sand has been washed, sieved and magnetically selected several times. Ensure that the product is clean and free of dust and fine particles, as these impurities are not cut.
3. The high-quality garnet waterjet sand has no water-blocking cutter heads, which ensures the continuous and stable operation of the water jet equipment.
in water jet cutting, we always use 60 mesh sand, 80 mesh sand, 120 mesh sand and 140 mesh sand.
