Thanks for your reply.

My problem is that the unit will not accept any date more than 2015.

Will return to 2011

The current software shows that it was built in 2013.

Hi all,

I have an old DVR that I want to upgrade its firmware because it has a problem.

But, I can not identify its brand.

I need your help to do so.

This is all I can post about it.

I've attached some photos of it.

I really appreciate your help.

BR,

Mahmoud
