Where is it on the Camera feed? Where is the Camera on the entrance of the building? We see the camera feed several times and while we see the entrance (where people hang out) but I dont recall seeing one showing the view from in front of the club, nor do I recall seeing a camera in any of the shots showing the entrance however I have not looked for one.
We see only a tiny fraction of all camera feeds. The building has dozends of rooms and facilities, and all of them are allegedly supervised, sometimes with more than one cam. We see only a handful of those cam-feeds and not all of them.
We know for a fact that there is no buzzing in system (or that it can be turned off) because the first day Edwin goes there Jacob is in the front staircase and Warren is in the bar area meaning nobody is by the cameras in the security room and thus nobody to verify to buzz them in all the same arguments can be made for the elevator. This means either the buzzing in system was toggled off, that Warren saw Edwin and Ian get in the elevator buzzed them in then ran down to the bar area before it went up less than a dozen floors (I kind of hope this is the case lol), or that the building does not have a system in place and is in fact less secure than your apartment building
This handy little intercom is small enough to not be seen from our perspective of the entrance.
It provides two tablets to conveniently access the camera, confirm your visitor and open the doors from any place in the building, as long as they are in range.
No running down the stairs anymore to receive your guest breathless in your preferred representative room.
We live in the 21st century and security cams don't need to be those bulky monsters anymore, infact they can be ridiculously and frighteningly small. The reason we have still this chunky and sturdy CCTVs in public is, because they are
meant to be seen to act as a
deterrent for potential crime and to withstand vandalism from perpetrators and violence against them.
And last but not least Edwin is usually expected to arrive at the club at specific hours, and Ian is already waiting for him in front of the door for his first visit. It's reasonable that Ian announced Edwins arrival, so Warren unlocked the various doors.
Also, Warren just has to leave the security room and head to the bar which is no further than max two floors away, while Ian and Edwin have to ride the elevator up to the 10th floor, walk up two more floors to arrive at the vestibule with Jacob, have a quick chat with him and then head upstairs again to arrive at the bar. That should take considerably longer than what Warren has to walk to the bar.
To assume they have all this security inside, but lack any information from outside and are unable to defend their perimeter with the most basic measure (a locked front door) is plainly unbelievable.
