[Rant]
Dear OP - Don't take personally, but this product description reminded me why I hate talking to customer service or technical support people from India.
I get it - English is not your first language, but neither it's mine.
In fact english is my 3rd language !!!
Yes, somehow I worked many years in US english speaking companies and have very little to no issues communicating with managers and colleagues.

Back to the subject:
Honestly this system is severely limited (to say it politely)
The best thing to do is to sell it and start from scratch
