Reolink Argus Series B440 with Solar Panel 4K Battery Camera

Reolink's Argus B440 redefines wire-free surveillance with a 4K UHD sensor and a 180° diagonal field of view, eliminating blind spots without a single cable. Unlike conventional battery cameras that compromise on clarity, this model pairs a 1/1.8" Starlight CMOS sensor with dual-band Wi-Fi for crisp, detailed footage day and night.
