Suppose I only want access from mobile devices on my local LAN, ie no internet, is it still necessary to use the Hik-Connect server?
Also, does Hik-Connect work without an NVR, ie POE switch only?
Finally, is there any limit to the number of mobile devices which can be connected to a single residential system? And if not, what happens if two people try at the same time to hold a conversation with a visitor or open a door? Is it first come, first served?
