China Film Science and Technology summarized buy high-quality digital LCD advertising attention; LCD advertising player applications are currently very wide could see their presence in shopping malls, buildings, financial institutions, airports and many other public places; for users, in currently messy bunch, product quality uneven advertising market to buy a high quality and cost-effective LCD advertising player must be on the overall structure and performance of LCD advertising have some understanding of where Shenzhen City Science and Technology digital Movies Ltd. specializes summary of matters relating to the purchase of high-quality LCD advertising to note that, for the majority of users reference.

      1, LCD advertising machine thing you see is the shell chassis, generally careful and check the inside shell of the weld Feng plastic glass is uniform.

      2, LCD advertising machine control cabinet, retaining nut, carefully review the screw holes with glass glue applicator gap, if there are from plastic or water, please first time to dismantle the holes waterproof glue real fight.

      3, watch the whole surface cleaning, internal checks whether the glass dust. Touch inside the glass to see if squeezed flat. Gravity heal, to see whether the blisters, bubbles, and if so, touch certainly failed.

      4, the chassis body to see the machine running noise, cotton insulation on the body to see whether the insulation, if the air conditioning noisy, cotton insulation is reflected are not, we must first take into account the air-conditioning cooling structure.

      5. Open the LCD advertising machine frame, try to close the door with one hand, if the pressure of the door touch, hard board also does not close the door, indicating that advertising machine frame design does not meet security standards. A door structure is not, then there is a problem is the lock assembly.

      6. gathered intelligence WIFI advertising machine Features:

      (1) WIFI wireless gathering advantages: a wider bandwidth

      Of course, the two projects intend to start IEEE 802.11 specification data speeds to gigabit or multi-gigabit advance, but so far has not yet formed the first draft.

      More realistic is the 802.11n specification data speeds forward a ranking, can adapt to differences in efficacy and equipment, at present, all 11n radios support two spatial data streams disassembly, send and receive data operable two or three antenna combination, Apple's latest WIFIiPod

    Touch to contain a Broadcom (Broadcom) wireless chip, support 11n specification.

     You can go through the process of 802.11s specification of these high-end nodes adjacent to it, the approximate aggregate composition WIFI Internet redundancy capabilities.

      (2) WIFI wireless 2 gathering advantages: stronger radio frequency lights mark

      11n in more optional performance features will now form a wireless chip, a wireless client and the wireless access point Ye dominate the chip enable radio frequency (RF) LED sign more flexible, reliable and constant, in other words more like a wire.

      (3) WIFI wireless gathering advantages: WIFI lower power consumption

      802.11n in power and RBI made a major refurbishment, not only can delay WIFI intellectual high phone's battery life, it can also be embedded into other devices, such as medical monitoring devices, building control systems, real-time location tracking labels and consumer electronics products. Inexhaustible able to monitor and gather data, can be based on commonality of the user's identity and status.

      (4) WIFI wireless gathering advantages: Improved stability

      Internet's most damage is the result of the impact of the process of identity theft, denial of doing things retaliation attacked attacks harm privacy, and trust means danger inquire embarrassed Organisation echoes of lead users, the mobile aggregation make this phenomenon worse, if users trust the current open WIFI contiguous, it is possible to make them at risk of Wild Things.

      (5) WIFI wireless gathering advantages: cooperation with non-aggregated WIFI

      If you are a T-MobileWIFI users, but at the moment you are in addition supplied within a carrier popular size, you can not operate the WIFI. In the future, your WIFI device can interrogate the "external network (other carrier's wireless aggregation)" of doing things, and can stably access your user identity and the way you travel around, so that you can operate all kinds of differences WIFI doing things.

      7. Try to choose well-known brands on the market such as Holley promise to protect the product after-sales service.
