Good day,

thanks a lot for your patience.

Did the auto-start only happen when the Surveillance Station tries to activate the camera?

If you try to live-view on the tpCamera APP,or https://www.tplinkcloud.com/, would the auto-start happen again?

How long have you had the camera？

Is there any change recently, like a firmware update?

And what is the model number of your main router?

Thanks a lot.

Thanks for help! And sorry, I just replaced this camera with a Reolink which I hope is more compatble with Synology.

Although I don't need help anymore, here is the info, :

-Tp link app worked fine

-I have had the camera for couple of years, all the time with synology and did not notice any problems,  bought 2nd hand

-camera had no sw updates but synology does autoupdates all the time, Surveillance Station version  is 8.2.8-6335 (which would have been my guess for the reason)

-main router is Huawei b315s

Thanks, Martti

Thank you very much for your detailed information.

And we would record the current case and it would be very helpful if other customers had the same experience.

Thanks a lot for your time and patience all the time.
