What Is Person Detection and Is AI Really Better Than PIR?

What Is Person Detection and Is AI Really Better Than PIR? comes down to matching the camera to the risk, the room, and the way you actually review footage.

Start with the job

A person detection camera should solve a specific problem: checking an entry, watching packages, monitoring pets, documenting a driveway, or adding evidence after an incident.

Features that matter

• Resolution: 1080p works indoors; 2K or 4K is better for distance and detail.
• Storage: Local storage can reduce monthly fees, while cloud storage is simpler for remote viewing.
• Power: Wired is best for reliability; battery is best for renters and flexible placement.
• Privacy: Avoid bedrooms, bathrooms, and private spaces unless disclosure and consent are clear.

Practical takeaway

Choose the simplest setup that covers the area, sends useful alerts, and keeps recordings accessible. A cheaper camera placed correctly usually beats an expensive camera pointed at the wrong angle.
