Hi all, I want to control my dvr (dahua) through rs232 (change the display, select camera 1, select camera 2, ...) I'm looking for informations about this, but impossible to find it, I also contacted Dahua through their website, but no answer ... anyone have documentation about this ? It would be very apreciated thanks a lot

hi, because it will not be possible to access the recorder ( the images will be projected on a giant screen ) I will create a small smartphone application that will let me control it remotely
