Q2: How long is the warranty time for your products?
Our officially promised warranty time is one whole year after delivery at best.

Q3: What is the difference between an IP65 air conditioner and an IP55 fan? What are the advantages of an air conditioner over a fan solution?
The principle is to cool the inside of the machine, the difference is that the fan is the external circulation of wind, the inside of the machine and the outside are connected, the air conditioner is to achieve internal cooling through refrigeration, and the cold air circulates inside. Compared with the fan scheme, the air conditioner has the advantages: it can withstand a more severe high temperature environment, and the internal space of the machine has less independent dust, which is suitable for places with high temperature. There is less dust inside than the fan. IP55 fans coolings system : -15 °/+50 ° IP65 fans coolings system : -40 °/+55 °

Q4: What are the standards for anti-corrosion, anti-rust, waterproof, lightning protection and explosion-proof?
1.The outdoor advertising machine is strictly 24H power-on and aging before leaving the factory, and tests the performance of the main board, temperature control, ventilation and heat dissipation; 2.Outdoor anti-corrosion coating can be used normally for 3-7 years without external force damage. The waterproof performance reaches IPX5, and each unit is equipped with a lightning protection switch.

Q5: What is the maximum outdoor brightness? Is there any change in the heat dissipation structure of different brightness?
Most of the sizes of high-brightness LCD screens can be selected in the range of 1000~3000CD/㎡. But some LCD screens have limits. It is recommended to use the range of 1500~2500CD/㎡, which is more conventional, and the energy consumption ratio is relatively suitable. It is recommended to use 1500CD/㎡ for products under 32 inches. Due to the large size and long viewing distance of 75 inches and above, it is recommended to use a brightness of 2500CD/㎡ or above.

Q6: What should be paid attention to in the outdoor installation site?
The outdoor unit can resist normal rainwater but cannot be immersed in water, as rainwater immersion will cause permanent damage to the accessories. - Avoid low-lying water areas when installing on the floor. -Wall mounting requires dedicated wall mounting screws on a firm wall. For example, the load-bearing capacity of a solid wall needs to be more than twice the weight of a wall-mounted outdoor advertising machine, and try to avoid installing it on an overturned wall. When installing, leave enough space for heat dissipation on the back and sides of the machine

Q7: What are the advantages of Gemdragon's outdoor machine internal structure layout?
1. Using high-quality LCD panels such as well-known brands (LG), the display effect is excellent, and the temperature resistance is higher than 68 degrees.

2. The front glass can be made of AG/AR anti-glare super toughened glass.

3. Using high-quality outdoor powder, it can withstand 3-5 years of harsh outdoor high temperature, light and humidity tests. The shell adopts galvanized sheet metal demolition and welding process, and the exterior is sprayed with outdoor paint for protection. Through waterproof structure sealing and ventilation and dustproof filter, the waterproof and dustproof grade can reach IP65;

4. The shell welding process is stable, the welding seam is even and smooth, and the deformation is small.

5. Add locking rods on the side, add screen support brackets, hinges and other accessories to fully test the structural strength and the safety of the equipment.

6. Adopt high-quality fan (CE EMC ROHS certification) to withstand high temperature and effectively dissipate heat.

7. The MEAN WELL power supply (CE EMC ROHS certification), a well-known German and Japanese brand, is used. Each channel is powered independently (for easy maintenance), and the power is redundant.

8. The circuit layout is reasonable, all cables are routed in wire grooves, no excess cables are exposed, high and low voltage are separated, and magnetic rings are added to prevent interference.

9. Built-in heater (CE EMC ROHS certification) to ensure normal use at low temperature

10. Preset 3-5 interface positions to facilitate later maintenance

11. A large area of silver insulation cotton is pasted on the rear shell to effectively reduce solar heat radiation.

12. Sufficient performance verification, screen outdoor aging screening, high and low temperature of the whole machine (-20 degrees to), user-use solar radiation simulation, shell size detection, paint coating adhesion test, EMC test (provide test report documents), high-pressure spray shower test

13. Built-in dust filter to isolate dust and foreign matter and ensure the safe operation of the equipment.
