1 Year WarrantyIncludedThe Algo 8028G2 PoE+ SIP Door Phone/IP Intercom is a secure, outdoor-rated IP intercom designed for hands-free guest contact at gates and doors. Wideband HD voice, PoE/PoE+, Secure SIP and a two-piece design that securely retains the network connection and door control relay within the building are all supported. The Algo 8028G2 is intended for secure entry points where regulated access and dependable communication are crucial. Its two-component design combines a separate PoE control unit with an outdoor-rated intercom station to help prevent tampering with the door release relay and network connection. This SIP door phone is an excellent choice for businesses, warehouses, hospitals, schools, lobbies and guarded facilities because it is compatible with both hosted cloud and premise-based VoIP systems. Additionally, it can make upgrades from analog intercom systems easier by supporting retrofit installs using pre-existing single twisted-pair cabling.
