Home Safety and Security Guides: Cameras, Locks, Alarms and Safes
Cover safety before security. Interconnected smoke and carbon monoxide alarms on every level and a radon test protect a family more than any camera. Then add locks, lighting, cameras and an alarm for the entry points a burglar would actually use.
These guides favor systems with local storage and no required subscription, and say clearly when a feature needs a paid plan.
