Switching between Wi-Fi AP and Wi-Fi STA − In Wi-Fi AP mode, the user terminal connects to the built-in Wi-Fi hotspot of the LCB4K. The default SSID is “AP+Last 8 digits of SN” and the default password is “12345678”. − In Wi-Fi STA mode, the user terminal and the LCB4K are connected to the Wi-Fi hotspot of a router.
Synchronous playback across multiple screens (1x 4K video) − NTP time synchronization − GPS time synchronization (The specified 4G module must be installed.) − RF time synchronization (The specified RF module must be installed.)
Support for 4G/5G modules The LCB4K ships without a 4G/5G module. Users have to purchase 4G/5G modules separately if needed. Currently only the 5G networks in China can be accessed. Network connection priority: Wired network > WiFi network > 4G/5G network When multiple types of networks are available, the LCB4K will choose a signal automatically according to the priority.
