dh-hac-hdbw1200ep

Hello! TL'DR: Does anyone have any experience accessing the OSD menu on the Dahua DH-HAC-HDW1200EMP? I live in the UK and have 4x Dahua 1080p HDCVI cameras (model number DH-HAC-HDBW1200EP PAL/30m/3.6mm PN: 1.0.01.12.11550) on my 8 way Dahua HCVR7208A-V2-1T, but I cannot access the OSD menus...
