With the recent popularity of Video Doorbell systems, Keri Systems announces the release of a new video doorbell/intercom system bearing the EntraGuard brand. Unlike other doorbell-only intercoms, these units are built with modern and attractive, ruggedized aluminum housings, and are also capable of unlocking an electrified door. Two models will be offered, the EntraGuard ONE permits video communication with a doorbell-announced visitor control on up to 4 mobile devices. Entraguard ONE+ adds Telephone-Entry style keypad PIN access. Features include 2-way live audio/video and motion-sensing that can trigger a call to your mobile.
