Description
Pressing the button of this video doorbell sends the user a push notification carrying an image, from which live viewing and a conversation can be started. A 4 MP CMOS sensor delivers up to 2688 × 1520 px in H.264 with HDR across viewing angles of 155° horizontally and 90° vertically. Movement is picked up by a PIR sensor reaching up to 4 m across 120° horizontally and 100° vertically, offering three sensitivity levels and supported by software image frame analysis plus AI object detection for people, pets and vehicles. Smart IR illumination works up to 6 m and adjusts its intensity in real time to avoid overexposure. A microphone with the G722 audio codec and always-active noise suppression and echo cancellation handles two-way communication. Connectivity covers an 802.11 b/g/n Wi-Fi module together with the Jeweller and Wings radio technologies, with NVR and Ajax Cloud Storage as storage options, JetSparrow as video protocol and conformance with ONVIF® Profile S.
