Angle is the number that matters here. A 30-foot detection range is ordinary in this group; a 150-degree sensor is not. Most of these units watch a narrow cone, so you end up buying two and aiming them at different gaps. The Grrwz sweeps roughly half a circle from a single stake, which makes it the pick for a corner where two fence lines meet.
You get two stakes, each with its own solar panel and a housing built for year-round weather. Setup is pushing the stake 9 or 10 inches into soft ground and switching it on, and a status light tells you the panel is charging. Nothing needs wiring, and there are no batteries to change.
The wide sweep has a side effect worth planning for. A 150-degree sensor picks up the dog crossing the lawn and you carrying a watering can, so it fires more often than a narrow unit does. Set it at the boundary rather than beside the patio and that stops mattering.
Bottom line: The pick for a corner where two fence lines meet: a 150-degree sensor covers both approaches from one stake, as long as you don't need to tune it.
