he enviado un correo a icantek preguntando por el firmware y esta es su respuesta:
I'm so sorry but we can't support your ask.
iCV390MP and Securitas Direct camera are different products even though same shapes.
So firmware of iCV390MP can't be uploaded to Securitas Direct camera.

Hoping your understanding,

No creo que me responda pero le voy a preguntar a que modelo equivale.......no creo que sea un modelo exclusivo para securitas direct......
