With multiple sensing technologies available, how do you choose the right one? Shenzhen StarCore Technology, as an expert provider, offers an objective comparison, highlighting where our 60G mmWave XKC-LD002 excels.

Technology Comparison Table

Feature	PIR (Passive Infrared)	Smart Camera (Vision)	60G mmWave (StarCore XKC-LD002)
Detection Principle	Heat Change	Image Recognition / AI	mmWave Radar Echo Analysis
Static Detection	NO	Yes (algorithm-dependent)	EXCELLENT (via vital signs)
Privacy	High (no image)	LOW (captures imagery)	HIGH (no image, point cloud only)
Env. Immunity	Affected by temp/airflow	Affected by light/obscuration	STRONG (immune to light/temp/smoke)
Material Penetration	No	No	Yes (non-metals)
Ranging / Multi-Target	Basic	Excellent	Good (provides distance & count)
Typical Cost	Low	Medium-High	Medium
Best Use Case	Hallways, basic motion triggers	Security, facial recognition, behavior analytics	Smart Office/Home, Elder Care, Energy Management (where static presence is key)

The Verdict:

For low-cost, motion-only triggering, PIR suffices.
For identification, analytics, and where privacy is not a concern, cameras are suitable.
For high-reliability static presence detection, where privacy, environmental robustness, and discretion are paramount in premium automation, StarCore Tech's 60G mmWave XKC-LD002 is the superior choice. It perfectly balances performance, privacy, and reliability.
