Security and 3G depth combination
2009 is the domestic 3G first year, the nationwide large-scale 3G network construction, bringing high-bandwidth, wide coverage, stable and reliable mobile communication network. This change will have a far-reaching impact on the security industry while changing the way people communicate. Take a clear and smooth 25fpsD1 format video as an example. If MPEG-4 compression encoding is used, it needs to occupy about 2M of bandwidth; if H.264 encoding is used, it also needs about 1.5M of bandwidth resources. This far exceeds the carrying capacity of a GPRS network with a theoretical bandwidth of only 172.1 Kbit/s. However, the emergence of 3G makes wireless video surveillance possible. Taking WCDMA as an example, its theoretical downlink rate is as high as 14.4 Mbps/s and the uplink rate is 5.76 Mbps/s, which can easily realize multi-channel wireless video transmission.
Fingerprint locks are becoming more popular
At present, some security manufacturers have developed wireless car monitoring front-end and car video server products, using the advantages of 3G network mobile convenience and high bandwidth, the front-end video compression coding and transmission to the central controller. This new product effectively solves the monitoring problems of vehicles, subways, trains and other vehicles that cable video surveillance cannot match. In addition, 3G can also be applied to video transmission after alarm triggering, and the remote alarm information triggers video response, which is transmitted to the user's mobile phone through the 3G network for real-time display. It is conceivable that in the future civilian-grade market such as home security and child care, the innovative application of security and 3G integration will be brilliant.
Take the lead in the process of digitization and high definition
Since the 2009 AMB conference, the analog to digital transformation, the development of SD to HD has significantly accelerated. In the security market in 2010, digital HD has become the protagonist. How to seize the opportunity, actively innovate in the digital and high-definition tide, launch boutiques, and become the key to seize the future market.
3-12mm Thickness Interior Wall Boards
Usually we call it magnesium oxide board mostly.
Magnesium Oxide Board is a new fireproof building material, main materials are magnesium oxide, magnesium chloride and perlite, and the materials react and generate cement-like substance, reinforced with glass fiber mesh and non-woven fabric, forming an excellent fireproof material. The product is used for walls, ceilings, fireproof door liner etc.Features
Compared with traditional gypsum boards/drywalls and fiber cement boards, Magnesium Oxide Boards have the following advantages
(1) Better fireproof performance: 15mm fireproof gypsum boards/drywalls reaches Grade B1 fire-resistant performance, 3mm Magnesium Oxide Board reaches Grade A fire-resistant performance.
(2) Waterproof: Gypsum boards/drywalls are easy to absorb water, tend to swell and deform in wet condition, Magnesium Oxide Board doesn't swell or deform in wet condition, strength is even higher in wet condition than in dry condition.
(3) Healthy: Magnesium Oxide Board doesn't contain asbestos, formaldehyde or benzene.
(4) High compatibility: Magnesium Oxide Board can be glued with various decorative materials such as wood veneer, PVC film, melamine film, brick, stone, aluminum foil, etc.
(5) Lower damage rate: Strength of gypsum boards/drywalls is lower than Magnesium Oxide Board, damage rate is high, fiber cement board is crisp, damage rate is high.
(6) Better sound insulation performance: Sound insulation effect of 95mm thick partition wall made of Magnesium Oxide Boards equals to 123mm thick partition wall made of gypsum drywall.
