How to control the LED screen from far away office.
Generally, the advertising LED screen is far away from office. It could be controlled by below methods:

- The control card is installed in the LED sign with one SIM 3G/4G card for network.
- The owner can control the LED sign from anywhere by network browser.
4. Optical cable extension. The fiber extension is used for synchronous control system for large LED screen better vision effect.
5. Need fiber sender and receiver. The single model fiber can support 10-20km distance. Multimode fiber supports 500m.
6. Remotely control. Keep one server that connect internet in the LED sign. Control this server by Teamviewer or other software.
7. But there is one risk. The server may be always stolen by someone.
