Ouch hey! The LED screen I just bought was controlled by WeChat, but Lao Wang changed the advertising slogans next door? Don't be anxious! Today we will talk about this heartbreaking question-​​How to set a password for the LED screen controlled by WeChat​​? You can learn it in three minutes if you are disabled! (Knock on the blackboard) This is a five-digit guide to prevent pits. Please move the small stool to listen!

1. Understand the underlying logic first: What is the purpose of passwords?

Let’s first imagine a scenario - you use WeChat to remotely modify the promotional information of the LED screen, and the competitors connect to your control channel to change the “50% off the entire venue” to “all-in-place suspension”.​​The password lock is to install an anti-theft door to the control channel.​! There are three specific things to do:

1. ​​Anti-informed content​: People without passwords cannot connect to the control background
2. ​Anti-voyeuristic data​: Playback record and customer information are fully encrypted
3. ​​Anti-operation prevention​: The cleaning lady will not touch the switch when wiping the screen

To give a real case: Last year, a chain supermarket used our transparent window screen. The clerk forgot to set up a password, but it was tampered with as a competitor advertisement at night, losing 300,000 yuan in turn!

2. Hardware preparation: These devices must be connected in advance

​Don't rush to get your phone​! Prepare these things first:

• ​​Control card with WeChat function​​: Check the QR code on the body (looks like a express order)
• ​​A stable power supply router​: It is recommended to use an enterprise-grade dual-band router, not a household model worth 99 yuan
• ​​Mobile phone and LED screen are the same as the network​: Either with one WiFi, or use 4G/5G signals

Like the fenced screen we made for the Korean stadium, there are twenty routers networking on site, and the password is set up with three layers of verification. This kind of professional protection even hackers will scratch their heads!

3. The entire process of setting password: Follow me and do it correctly!

​​The key point is here! Starting with step-by-step teaching​：

1. ​​Scan the code to bind the device​​
   Open WeChat and scan the QR code on the control card, and an interface like a mini program will appear. Notice!​​Don't click "Remember password"​, otherwise the cleaner can operate it!

2. ​Enter security settings​
   Find the icon that looks like a gear in the control interface, click on "Permission Management". There is a pit here - many novices cannot find the "second-level password" option, but in fact, they must first activate the administrator identity in the "Basic Settings"!

3. ​Set two-factor verification​
   Strongly recommended to set up​"Operation Password + Time Lock"​Combination punch:

   • Operation password: At least 8 digits include upper and lower case letters, don’t use birthday!
   • Time lock: For example, the setting is 18:00 every day to 8:00 next day, the modification is prohibited

The floor tiled screen we made for Japanese customers uses dynamic password technology - the password will automatically change every time we log in, and the security will be fully increased!

4. Common car overturning scenes: Don’t step on these minefields!

Teach your lessons from blood and tears, friends! I've seen these pitfalls countless times:

• ​​The password is set and will not take effect​？
  Eighty times the control card has not been restarted! Just like rebooting your phone with a card replacement, you must have a power off for 30 seconds after setting your password.

• ​​Can connect to WiFi but cannot change the content​？
  Check the router firewall settings and add the control card IP address to the whitelist

• ​​The screen displays "Insufficient Permissions"​？
  It means you are using a sub-account! The main administrator has to let you make permissions in the background. This process is similar to that of the company's OA system.

One customer was even more outrageous - he put the control card in a glass cover, and the signal was blocked. Later our engineer taught him how to use it​Extended antenna + metal shield​, perfect solution to the problem!

5. Upgrade gameplay: These advanced functions make you feel so happy!

Do you think password locks can only protect people? Too naive! The current black technology can still:

• ​​Fingerprint/face double authentication​: Face ID for iPhone and fingerprint for Android
• ​​Operation record traceability​: Who changed what content at what time? It's clear
• ​​Off-site synchronization lock​: The screen at the headquarters has been changed randomly, and all branches automatically lock the screen

The curved screens we made for Singapore shopping malls are even more amazing-​​GPS Fence Lock​! The equipment is automatically locked when moved out of the mall, and the thief will turn into scrap iron when they move it away!

Editor's opinion time

If you ask me, setting a password is like locking your door - you may find it troublesome, but it can help you when something really happens! Especially manufacturers like us who have done Tokyo Olympics events are the most aware of the importance of safety protection.

Now LED screens are no longer just display tools, they are connected to your data assets and business secrets. Instead of waiting for something to happen, it is better to spend five minutes to set a reliable password now. After all,​This is a matter of safety and is better than to lose the situation.​! Do you think this is the reason?
