Dahua new models: 180° Wide-angle camera IPC-HFW3441T-AS-P and IPC-HDBW3441R-AS-P

Has anyone purchased the IPC-HDBW3441R-AS-P ? Any impressions? Reasons to not buy? I just purchased a IPC-HDBW5441F-AS-E2, the boobie cam to replace an older 2M version but lost vertical FOV and the IPC-HDBW3441R-AS-P has 78° which would be an improvement in that respect. It is for double driveway awareness not identification..
