No cables, no wiring and no worries - "100% wireless" should be that simple. Place the Reolink Argus 2 anywhere you want - on a shelf, on the wall, on the front door, at the construction site, in the holiday home, etc. and move the camera from one location to another as desired. Two types of energy supply are available: Rechargeable battery (included) If the battery is low, simply remove the battery and charge, done. Then the camera works again "full of energy". Replacement batteries are also available in "Accessories". Solar Panel (optional) Connect the camera to Reolink Solar Panel for 24/7 protection. The weatherproof solar panel is easy to install and allows uninterrupted power supply.
