Yes and No.
There’s a huge difference here.
All the surveillance video is strictly internal to DMS and not accessible to social media, etc.
Someone roaming the Space w/ camera needs to keep in mind what their end purpose/use is.
You very well may need a release form signed. And keep in mind a verbal agreement probably won’t go far in court.
This has been a legal topic/problem for photographers for decades.
Photograph someone working on IP/Patent project, put their pict and name out on social media, get sued.
And rightfully so. You may have just blown their ability to finish the patent process and gave the competition a heads up.
Also some folks simply do not want their pict along with their name out on social media given google, faKebook, etc gather/aggregate this info.
Bottom line is simply this: Professional courtesy says you ask before shooting/posting. Doesn’t take long and may save someone a lot of legal grief.
