The Reolink Argus Series 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 a microSD card slot (up to 512GB – card sold separately). Mount camera and solar panel to outdoor walls, ceilings, eaves or even trees. Perfect for light-commercial and residential properties with reliable Wi-Fi. | Reolink | | Argus Series B440 4K 8MP Solar Home Security Camera Outdoor Wireless Wi | Fi with Auto-Tracking Pan Tilt | White | Best Buy
