1. The whole structure is waterproof
Now the outdoor LCD advertising machine is waterproof only with the waterproof structure of the car, and the level can reach IP65.
2. Cooling scheme
Now there are four cooling solutions on the market for reference
1. Air cooling
2. Air conditioner cooling
3. Heat exchange and heat dissipation
4. Water cooling
Among them, air cooling is the most widely used cooling method. Air-cooled heat dissipation is a heat dissipation method developed by using a speed-adjustable fan combined with a professional heat dissipation solution. Its advantages are low power consumption and low cost. This helps reduce the cost of later operations. However, the disadvantage is that the protection level is low, which can only reach IP55. Regularly clean the filter plate and check the operation of the speed-adjusting fan. Applicable to most parts of the country, except northeast, northwest, Hainan, areas with relatively high humidity, coastal cities, and heavily polluted areas.

The air-conditioning cooling solution is the most widely used cooling method for external use. Its advantages are large heat dissipation, high protection level (IP65), wide application range, stable performance and long life. There are advantages and disadvantages: high power consumption, high cost, high operating cost. Applicable all over the country
Heat exchange cooling advantages: low power consumption (close to air cooling), high protection level (IP65). The disadvantages are: high cost (higher than air conditioner) and low heat dissipation. Only suitable for areas with particularly suitable climate
The water cooling system is not very mature in the whole technology, so it is not recommended to use it.
3. Brightness selection
Brightness is one of the important parameters of outdoor high-brightness screens. At present, there are two kinds of backlight modes: linear and side-illuminated.
The direct-type backlight has high brightness, and the side-emitting brightness is only suitable for small-sized screens (screens below 32 inches).
4. Playing method:
So far, there are two playback methods, Android and PC (small computer) are used more. Of these two playback methods, pure advertising playback is more suitable for Android, and the cost is low, and it can remotely control multiple devices, truly realizing cross-regional remote control. And the Android version of the software is free to use. The PC solution is mainly used for more flexible touch, and of course the Android version can also do touch functions. This is mainly based on the needs of the customer. The touch software is customized by the customer (Party A). Because the content of the touch is set by Party A.
5. Playback control:
Now the remote control has realized this function, the main difference is that Android is free to use, and the X86 (PC) information distribution system is charged (charged by point, more than 400 points less, and more than 300 points) according to customer needs choose.

6. Networking method:
There are three ways of networking on the market: network cable, wifi, 3G/4G networking
Wired networking: The networking is more stable, and the installation cost in the early stage will increase, which is suitable for short-distance use (community)
WIFI networking: the cost is low, and the restrictive factor is the regional limitation of wifi hotspots, and the general trial is related to shopping malls, shops, etc.
3G/4G networking: 3G/4G networking is the most used networking approach, and 3G/4G networking has two
Modes: 3G/4G module, 3G/4G router, if there are only 1-2 ports in a set of equipment, only 3G/4G module is required for networking, and more than three ports need to be networked, using 3G/4G router plus switch and the actual point . 3G/4G networking will incur traffic charges and additional costs will be incurred later.
