Reolink CX820 4K (8MP) Dome PoE IP Camera — F1 Super Aperture, Color Night Vision, Person/Vehicle/Pet Detection

Overview: The Reolink CX820 is a 4K 8MP dome PoE IP camera with an F1 super aperture and Color Night Vision, designed to deliver clear footage and precise alerts without monthly subscription charges. Advanced object classification analyzes shapes to distinguish people, vehicles and animals, cutting down on false alarms and sending only relevant warnings. Accurate Alerts & Smart Event Detection: Built-in intelligence provides Virtual Fence Alert, Zone Intrusion Alert and Zone Linger Alert so you’ll know immediately if someone crosses a boundary, enters a restricted area, or lingers too long. Push and email notifications arrive in seconds; detection sensitivity can be adjusted for fewer false positives. Two-Way Audio & Active Deterrence: A built-in microphone and speaker let you speak in real time to visitors or intruders. When motion is detected, the camera can trigger a dual deterrent — a scheduled warm light and a siren will activate together to discourage unwanted activity before it escalates. Storage Options: Choose local or networked storage to suit your needs. Save footage on a microSD card (supports up to 256 GB), record to a compatible Reolink NVR for multi-camera management, or back up clips to an FTP server for extra redundancy. Installation & Durability: Power over Ethernet (PoE) carries both data and power over a single Ethernet cable, simplifying installation. The CX820 is rated IP67 for reliable operation against water, dust, heat and cold. Playback, Timelapse & Live View: Create condensed timelapse videos to capture long periods in short clips. Smart playback tools with event and timeline filters let you quickly find the moments you need. Live view is available anytime via the Reolink App or Client. Custom Monitoring & Voice Control: Define custom detection zones to focus on the areas that matter most. For hands-free viewing, use voice and cast controls with Google Nest Hub or Chromecast-enabled TVs — for example, say "Hey Google, show me the Front Door."
