100% wireless and freely placeable. No cables, no wiring, and no worries – that's how simple "100% wireless" should be. You can place the Reolink Argus 2 anywhere – on a shelf, on the wall, at the front door, at the construction site, in the vacation home, etc., and easily move the camera from one location to another. Two power supply options are available: a rechargeable battery (included). When the battery is low, simply remove the battery and recharge it, and you're done. The camera will then operate "fully energized" again. Replacement batteries are also available as accessories. Connect the camera to the Reolink solar panel for 24/7 protection. The weatherproof solar panel is easy to install and provides uninterrupted power supply. See everything in true 1080p Full HD resolution – much sharper and clearer than 720p. Thanks to the star light CMOS sensor, the camera delivers high-quality image quality and a high night vision range of up to 10 meters in all lighting conditions (from sunlight to starlight) – external lighting is not required. With a 130° wide-angle view and a highly sensitive PIR motion sensor, false alarms are minimized. Once motion is detected, sound alarms or your custom alarm messages will sound, and you will receive instant push notifications and emails, allowing you to take appropriate action in real-time. Listen to what is happening inside or outside your home and respond immediately. With the built-in microphone and speaker, you can communicate with your parents, children, babysitters, pets, etc., or warn unwanted guests, no matter where you are.
