Hikvision: Siren/Light control via App

[Chucklehead]

I'm very happy with my Hikvision cameras but my god the usability of the apps, browsers, direct log in, camera log in and all other variables is tiresome to get to grips with.

I have managed to get audio working on the app, but my camera also has light and siren function that i want to use. I don't want it to go off any time it's triggered, but instead i want to be able to manually activate it using the alarm button on the app.

Does anyone know how i can do that??
