The EZVIZ CB3 2K Wi-Fi Battery-Powered Camera (Model: CS-CB3, 3MP, 2.8mm Lens, 5200mAh) is a standalone, wire-free outdoor security camera designed for easy installation and robust performance. Featuring a 2K resolution (3MP, 2304 × 1296), it captures crystal-clear footage with a 2.8mm lens, providing a wide 110° diagonal field of view (94° horizontal, 50° vertical) and an F1.6 aperture for enhanced light capture.

The camera’s Always-On Video (AOV) technology enables 24/7 time-lapse recording by capturing images at preset intervals, supplemented by normal video during significant human or vehicle activity, ensuring comprehensive monitoring with efficient power management.Equipped with a 5,200mAh rechargeable lithium battery, the CB3 operates for up to 120 days on a single charge (based on 5 minutes of daily use, per EZVIZ Lab tests).

It is compatible with EZVIZ Solar Panels (Type-C version, sold separately), allowing continuous power with just a few hours of daily sunlight, eliminating manual recharging. Its IP66 weatherproof enclosure ensures durability against rain, dust, and snow, operating in temperatures from -20°C to 50°C with humidity up to 95% (non-condensing).The CB3 integrates advanced AI-powered human and vehicle detection, using a PIR sensor and person-shape detection algorithm to filter out irrelevant motion (e.g., pets or foliage), delivering smarter notifications via the EZVIZ App. It features color night vision up to 15 meters (49 feet) with two built-in spotlights (non-flashing in color mode) and infrared night vision for clear imaging in total darkness.

The “smart night vision” mode automatically switches to color upon detecting motion. An active defense system triggers a loud siren and flashing spotlights to deter intruders, while two-way audio supports real-time communication or pre-recorded 10-second voice messages (e.g., “Private property. Please do not enter!”).
