Frequently Asked Questions
Can an intercom system be used to grant access remotely?
Yes. IP-based intercom systems allow authorized personnel to see who is at an entry point via video feed, communicate with them, and remotely unlock the door from a smartphone, desktop, or any network-connected device.
Can intercom systems work in older buildings without structured cabling?
Yes. NSC offers wired and IP-based intercom solutions. IP systems leverage existing network infrastructure, and wireless options are available for retrofit installations where new cabling is impractical.
