Sannce Security Sustem Digital video recorder

PLEASE READ CAREFULLY. This is a security system that was purchased by my husband and he had put in storage accidentally. The brand is SANNCE the model number is DH81S. for the DVR box thst comes with a remote control that he bought separately. The system came separately with 4 cameras. This has all of the cords, a memory disc,, a sticker for your window & more. . The box has been opened but nothing has been used. There is a separate box ( JUST THE BOX) that I cannot locate for the remote control and DVR. as you can see though it is brand new not even a scratch on it. PLEASE DO message me with any questions you have. Again I will EMPHASIZE that this box was opened,, never used or installed. From what I know, I do believe all of it is here. I will say not 100% positive. There are even extra cords.
From what I can tell this would still be a great security system. Please make REASONABLE offers only! THANK YOU
