Hi, i live in a large residential highrise and the building management are going to be installing a cctv camera on my floor to try and eliminate visitors to the floor who are not meant to be there (they come as there is a great viewing area, but also can have mini parties/smoke drugs etc). The cctv company provide either Hikvision or Dahua cameras. My issue is that i dont want the front desk concierge team seeing me appear on their camera everytime i step foot outside the door to my apartment. Instead want my corridor that leads into the foyer that needs monitoring, to be blocked out. Ordinarily you would just say at this point, angle the camera appropriately to do that. But, my neighbour (behind door B) does want the corridor filmed in case of situation where a delivery to door goes missing etc. So the question is; do either brands have a system where you can be filming all areas (via 180 deg cam), but, have part of the area blacked out so front desk cannot see that bit, but, be still recording what is happening behind that "curtain" in case there is an issue and building management need to go back and view the footage? or is there some alternate way to be able to record the hallway, but that part not be visible to building staff? I have attached a floor plan to help make it easier to follow. I am located behind the door A, and want to get to the lifts without being watched by building staff. Door C is door to stair well. Thanks in advance!
