Or use it on a temporary construction site, in a rented house or on a weekend cottage. It is waterproof and suitable for indoor and outdoor use. Rain or shine, heat or cold - this camera will never give up. The Reolink Argus 3 4MP camera comes with a rechargeable battery, which allows charging directly from the socket or using a Reolink solar panel.
