Help identifying generic HI3515 Chinese NVR please

Hi guys I hope you can help. I have an NVR that I bought while in China, however I need to see if there is an update supporting P2P as I've recently changed from ADSL to cable and there is no support for fixed IP or DYNDNS from my new ISP.

I've tried searching from the info on the sticker, but turned up nothing. The chipset is HI3515. Photos attached.

I dont know if I could maybe flash it with another manufacturers compatible firmware if the chipset is generic?

Its currently on V4.02.R11.00000085.12001 Build date 13/06/2013. I dont know if that helps pinpoint it?

Any pointers would be greatly appreciated!
