Mx-Gps box falsetick

I have problem to configure a gps box on other cameras. On main camera where is gps i regular, everything is ok, but on other camera it shows me a “falsetick” can anybody help me with that?

Hello @buda992,
so you installed one gps box on one camera which is the time-server for the other cameras?
So you activated the point: use camera as time-server and entered the ip-adress of this camera into the other cameras as NTP-Server?
Could you post a screenshot of this failure?
