Description
Ajax DoorBell has been designed to modernize the traditional video door entry experience, integrating a compact design and advanced security technology within the Ajax ecosystem, through the JetSparrow transmission protocol, developed by Ajax for the efficient transmission, storage and management of video data. It is designed to provide ultra-fast and stable real-time video streaming with no delays or interruptions. Uses peer-to-peer (P2P) technology and TLS encryption, ensuring secure data transmission. Thanks to its high efficiency, it allows smooth navigation in both live viewing and archiving of recordings, optimizing the monitoring and security management experience.
With long-range Wi-Fi connection and secure backup, the Ajax DoorBell operates with Wi-Fi 2.4 GHz, but in case of network failure, it guarantees continuity thanks to the proprietary Jeweller and Wings protocols.
