- Security cameras raise privacy concerns; motion sensors offer a privacy-friendly alternative.
- An old-school radar system (e.g., Dakota Alert) provides up to half-mile range, no Wi-Fi, and reliable outdoor detection, but battery life is short.
- The Kini motion sensor is ideal for securing cabinets/drawers, with customizable alerts via app, email, or webhooks, and a Stasis mode for reverse monitoring.
- Other motion sensors like Eve, Aqara, Switchbot, and Philips Hue vary in compatibility (hub required) and features, with some offering presence detection and smart home integration.
- Smart lights (Wiz SpaceSense, Philips Hue MotionAware) can detect motion using Wi-Fi or Zigbee, but effectiveness depends on light layout and may require a subscription for alerts.
- Modular security systems (SimpliSafe, ADT, Eufy, Arlo) and age-tech solutions (Nomo Smart Care) provide additional alternatives for home monitoring without cameras.
