Best Solar 4K System
REOLINK Argus PT Ultra 4K Solar Security 4 Pack
Our verdict: Four solar-powered 4K cameras that remove most of the battery chores.
The Argus PT Ultra is a four-pack of outdoor 4K cameras with solar power, priced $200 to $500. 4K means a sharper image than the 1080p of most budget kits, and the solar panel keeps the battery topped up.
It ranks first because it solves the two weaknesses of wireless cameras together: the picture is detailed enough to read a number plate at a modest distance and the power source is largely self-sustaining. The PT in the name refers to pan and tilt, which lets one camera cover a wider area than a fixed lens. It costs more than the Blink kits and relies on enough daily sun, so a shaded wall will not keep it charged.
Buy it for a yard with a clear south-facing wall or post. Skip it if the cameras will sit in permanent shade.
