Alas, have you ever seen the embarrassing scene of suddenly black screen at the concert? That is probably caused by the inadequate installation of the front screen! Today we will talk about this problem that makes newbies trouble - how to find a reliable and cost-effective installation solution?

These three moves to prevent overturning than to install fast

The organizer of a music festival fell into this last year. The stage screen was tilted forward 15 degrees at halfway through the performance, which scared the security guards to clear the scene directly. Later I found out that​ ​Load-bearing bracket cuts corners​​, do you think it’s wronged?

• ​​Must-see parameters​​：
  → Load bearing per square meter ≥80kg (equivalent to 4 adults stationed)
  → Horizontal adjustment accuracy ±0.5° (more accurate than mobile phone gyroscope)
  → Wind resistance level 8 (not afraid of level 10 typhoons)

Is the quick dismantling structure really reliable? Tested data speak

A satellite TV station used the New Year's Eve party​​Magnetic quick disassembly system​​, the disassembly and assembly speed is 3 times faster than the traditional screw fixation. But there are some tricks here——

• ​​Material comparison​​：

  Material Type	Life cycle	Time-consuming for a single disassembly
  Ordinary aluminum alloy	500 times	8 minutes/㎡
  Aerospace aluminum magnesium zinc	2000 times	3 minutes/㎡

• ​​Lessons of blood and tears​​: Never choose plastic snaps, as the temperature difference is large and it is easy to brittle and break

Waterproof and dustproof are not merely understood by looking at this set of numbers

Last month, a shopping mall had a short circuit in the front push screen, and the maintenance fee was directly burned to 180,000 yuan. Actually, the key is​ ​Protection level​​：

• ​​IP54 level​​: Can prevent shower-type water spray (suitable for indoor use)
• ​​IP65 level​​: Can resist high-pressure water gun flushing (must-have outdoors)
• ​​Cold knowledge​​: The real dustproof test is to blow talc powder continuously for 8 hours

Signal transmission distance shrinks? Maybe the wire is damaging

My buddy has suffered this loss when he drives a livehouse. The 20-meter-long signal cable actually transmits less than 15 meters and then it will be filled with the screen. Later it changed​ ​Double shielded silver-plated wire​​Only solved:

• ​​Purchase tips​​：
  → Choose a normal line within 5 meters
  → 10 meters to carry a signal amplifier
  → Fiber must be transmitted over 20 meters
• ​​Tips for saving money​​: On-site testing of transmission stability of your own equipment

I have to say that now there are "professional installation" on the market, and eight out of ten companies can't even do basic wind load calculations. Remember, dare to take it out​ ​Third-party testing report​​and​​Five-year warranty commitment​​The supplier is really reliable!
