No sir, LED Indicates/glows Solid Amber like setup process connected through wired connection.

Now i have removed it and connected using wifi. To check if problem still persist. Using of adapter is not an ideal option for me as its connected to remote location without any electric wire or power outlet.

  @Wayne-TP Sir

With WIFI connection, now i can see 6 hours of uninterrupted video recording, means working great in with WIFI.

So is it possible that the camera has some kind of fault with it's wire connection module ?

  @Wayne-TP  Sir i was happy untill i checked the camera recordings. After connecting through wifi, the problematic works okay okay, no stream inturuption, no amber light indication But on recordings i found every 10 to 20 minutes two tapo cameras are rebooting simultaneously. Both the cameras are power by Mercusys POE switch wih tp link splitter as mentioned before. I ahve turned off auto recovey on the switch. Isolate 1-4 port is turned on. So What could be the reason that both the cameras are simultanously rebooting ? I Don't think that it's switch problem because, total 3 cameras are connected to switch 2 tapo camera and 1 Ezviz. Ezviz camera is not rebooting and not found any streaming inturuption on recordings.
