@Solla-topee The user AlquimistaMDev describes exactly my scenario. I planned to install a Tapo system for a customer, but he requires a loud alarm that rings until confirmed. Using a Tapo Hub is not an option, since the owner is not always at home.

@Solla-topee - The ability to set the notification sound on iOS on a PER camera basis has been part of one of your competitor's camera app for a long time now.

So it isn't as the recommended solution for this thread says, something that needs to be brought up with "phone support' aka Apple.  It is something within your app developer's control.

Hello, I would like to add a request for a feature to set a custom notification sound. It is unbelievable to me that the software does not have such a basic feature.
I own a Tapo C410 with a solar panel because I am having trouble with thieves on a property without electricity. The camera is fantastic in most respects, energy efficient, with excellent detection. It's just that it's all useless if the camera doesn't wake me up at night if there is movement on the property.

Not being able to set a custom alarm sound when motion is detected is a major issue and makes the camera a toy. During the day, when I have my phone with me, I know about movement immediately, but as we all know, burglars don't usually come out during the day, and if the camera doesn't wake me up at night so I can call the police, it's useless. The thief comes in, destroys the camera in peace and I don't find out until the morning from the paid cloud. It really degrades the useful function of the camera in detecting uninvited guests to almost zero.

So, I beg for everyone to add such an essential feature as being able to choose your own distinctive sound when detecting movement on the property. Thank you
