Security Cameras
My property is looking into installing a security camera system campus-wide. It is a 4 building property. 

Who do you use for security camera systems and why? Are you happy with the system in place?

A lot of vendors are pushing HIKVision but I’m not sold on them. 

All input is appreciated.

However, they are still stupidly insecure and need to be secured against open public access as well as your internal network systems.  \n", "replies": [], "depth": 1}, {"id": "ec5fmlm", "text": "How many cameras are you looking at installing throughout the property?
