Hikvision Intercom - Sliding Gates

HI All,

I’m looking at adding the Hikvision intercom system to my existing NVR setup to control a sliding gate for access to my property and have a couple of questions...

Are the hikvision intercom systems compatible with sliding gate opening systems?

Can they support GSM as well for gate opening (thinking “call home gates” from car as approaching gates to have the open rather than fumbling for app button).

Can the intercom camera always be recorded on NVR?

Can calls from the Intercom...
