@Nidstang Thanks for your reply. It seems that the camera failed to update the firmware. May I know the mac address of the 2 cameras？ Which can be found on the bottom label of the actual device.

@stawo You can enter your e-mail address as Recipient E-mail Address and Sender E-mail Address both.

@lachinelli The NC450 V2.1 uses the new package, while the software functions of the V2.1 and V2 are the same.

@Warleys Do you use the web UI or the tpCamera app to watch the recordings? Meanwhile, JPG is picture format, not video, may I know where did you see the JPG videos? Please show us a picture of it....

@Mare Thanks for your reply. At that point, please connect your computer to the C3150 and click here to check its IP address and gateway. Meanwhile, please try to ping the gateway of the main router...

@NewDad What is the led status of the KC120? Please move it closer to the main router and test whether you can see the liveview. Besides, you can try to hard reset by holding the reset button for 15s...
