Detection range

Reviewers report the S4 Max can detect people and vehicles reliably at typical driveway distances and can even register motion roughly 150 feet away when aimed across a street.

Reviewers report that the Argus 4 Pro can detect motion close to 100 feet away while still distinguishing between people and vehicles, and this article reinforces that it reliably picks up activity at about 95 feet and can still provide plate level detail around 45 to 50 feet when aimed toward a distant street.

This review reports that the E340 can reliably detect and track a person walking across a typical front yard, picking up motion from near the house out to the driveway and covered areas without losing the subject.

With sensitivity set high and person detection enabled, the Duo Cam Pan can detect a person at roughly forty feet, offering solid range for typical front yard or driveway coverage.

With 24/7 capture enabled the C660 can detect a person standing roughly 40 feet away using camerabased analysis of frequent snapshots, whereas relying only on the PIR sensor with continuous capture off brings the effective trigger distance closer to around 20 feet, and this review also points out that the small PIR window can miss motion at the very edges of the frame when the head is tilted up, leading the reviewer to strongly recommend leaving 24/7 capture on for maximum practical detection coverage.
