Napco Brand


Alarm lock is a NAPCO brand.


AirAccess – a cellular- & cloud-based system that uses Napco’s well-known StarLink Cellular to automatically make network connections, outside the customer’s IT dept network and firewall. It eliminates setup hassles, IT delays/interactions, ISP changes, etc, and can use your choice of any Wiegand readers with wireless 1-Door panels, or top-rated wireless access locks inside or out, or both. And it offers twice the RMR-earning potential because dealers can not only host /manage their accounts’ systems remotely at the dealer’s own server, but also provide them with cellular central station monitoring and SMS cellphone alerts, as well.
