The Reolink Argus PT Ultra B440 4K 8MP Solar Wireless Wi-Fi Pan and Tilt Security Camera is ideal when you need full coverage of large outdoor areas - but don't have an electrical outlet. When Auto-Tracking is enabled, this battery security camera will "follow" people, animals and vehicles automatically. You can also use your Reolink smartphone app to move the camera manually in a full range of motion. 4K ultra-high definition (8-megapixel) resolution means your footage is crisp and un-pixelated - even when zoomed in on faces or license plates! Person/Vehicle/Animal detection algorithms greatly reduce false alerts. Trail camera records locally to an included 64GB SD card (up to 512GB max). Mount camera and solar panel to outdoor walls, ceilings, eaves or even trees. Perfect for light-commercial and residential properties with reliable Wi-Fi.
