This Hall was an RBC construction project about five years ago. The digital projector and cameras were installed last month.
I understand the need for practical security. The most perplexing shot was of the elder's meeting room - where judicial cases are heard.
The use of live feeds may give a sense of a secure meeting place for the publishers. It also can fuel fear of persecution from the outside.
Another thought - with the elder's room is being monitored perhaps this is a way record any who enter and look through the physical files, make copies of documents or transfer sensitive information to a flash drive/memory stick...
