Pay attention to the purchase of high-quality LCD advertising players; at present, the application fields of LCD advertising players are very wide. They can be seen in many public places such as shopping malls, buildings, financial institutions, airports, etc.; for users, the current chaos and product quality The uneven advertising machine market. To buy a high-quality and cost-effective LCD advertising machine, you must have a certain understanding of the overall structure and performance of the LCD advertising machine. Here, Shenzhen Hualinuo Technology Co., Ltd. professionally summarized the purchase Matters needing attention in high-quality LCD advertising machines are for reference by users.
1. The first thing the LCD advertising player sees is the case of the shell. Generally, pay attention to check whether the glass glue on the inner side of the shell is even.
Advertising player
2. Compare the case of the LCD advertising machine, fix the nut, and carefully check the gap between the screw hole and the glass glue. If there is separation or water ingress, please disassemble the hole as soon as possible to make the waterproof glue firm.
3. Watch the surface of the whole machine clean and check whether there is dust inside the glass. Touch the inside of the glass to see if it is squeezed smoothly. Use gravity to smooth it and see if there are blisters or bubbles. If there are, the touch will definitely be unqualified.
4. The case body depends on the running noise of the machine and whether the insulation wool on the body can insulate the body. If the air conditioner is noisy and the insulation wool does not reflect at all, the heat dissipation structure of the air conditioner must be considered first.
5. Open the door frame of the LCD advertising machine and try to close the door panel with one hand. If the door panel touches the pressure bar, the door panel cannot be closed with force, indicating that the design of the advertising machine door frame does not meet the anti-theft standard. One is the failure of the door structure, and the other is the problem with the lock assembly.
6. Gather the characteristics of smart WIFI advertising machine:
(1) WIFI wireless aggregation advantages: wider bandwidth
Of course, the IEEE has initiated two projects to advance the data speed of the 802.11 specification to gigabit or several gigabytes, but it has not yet formed a draft.
More realistically, the 802.11n specification advances the data speed to a ranking, which can adapt to different functions and devices. At present, all 11n wireless transceivers support two spatial data streams, and two or three data streams can be operated for sending and receiving data. Antenna combination, Apple's latest WIFIiPod
Touch contains a Broadcom wireless chip that supports the 11n specification.
You can connect these high-end nodes through the 802.11s specification to form a redundant WIFI cluster similar to the Internet.
(2) WIFI wireless aggregation advantage 2: stronger radio frequency light mark
More optional performance features in 11n will be present in wireless chips at this moment. Wireless clients and wireless access points dominate these chips to make radio frequency (RF) light signs more flexible, constant and reliable, in other words more Like a wire.
(3) WIFI wireless aggregation advantages: WIFI lower power consumption
802.11n has undergone major renovations in terms of power consumption and management. Not only can it delay the battery life of WIFI Chicco phones, it can also be embedded in other devices, such as medical monitoring equipment, building control systems, real-time location tracking tags, and consumer electronics products. Ability to monitor and aggregate data endlessly, and to make commonality based on the identity and status of users.
(4) WIFI wireless aggregation advantage: improved stability
The most destructive effect of the Internet is the theft of identity verification through the process, refusal to retaliate against attacks, privacy violations, inquiries and embarrassment of the trust methods that cause danger to users. Mobile aggregation makes this phenomenon worse. If so Users trust the currently opened WIFI connection, which may cause them to encounter the risk of killing.
(5) WIFI wireless aggregation advantage: cooperation with non-WIFI aggregation
If you are a T-MobileWIFI user, but you are currently in a popular scale provided by another operator, then you cannot operate WIFI. In the future, your WIFI device will be able to query the "extranet (wireless aggregation of other operators)" and be able to access it stably. Your user identity will travel with you all the way, enabling you to operate all kinds of different WIFI Do things.
7. Try to choose well-known brands in the market such as Hualinuo to ensure the after-sales service of the products.
