AI cameras are central to Smart Home Safety for the elderly, but quality AI cameras must perform local inference to protect privacy and comply with Thailand’s Personal Data Protection Act (PDPA, 2019). HappySmart selects Frigate NVR as its primary AI video analytics platform precisely because it processes all footage locally on a home server.
Frigate NVR runs on a Raspberry Pi 4 with a Google Coral TPU Accelerator (2,000-3,000 THB) that handles object detection 10-15 times faster than CPU alone. It supports any RTSP-compatible IP camera. The Reolink 510A at 3,500-4,500 THB is the most popular choice, featuring built-in AI object detection and PoE connectivity.
Behaviors that AI cameras can analyze: (1) Fall Detection — identifies a fall by tracking the bounding box of a detected person changing from vertical to horizontal within 0.5 seconds, achieving 87-92% accuracy; (2) Inactivity Alert — triggers when an elderly resident remains motionless within a defined zone for over 30 minutes; (3) Wandering Detection — alerts when a resident with dementia exits a predefined safety zone, such as leaving the home at night.
PDPA compliance: Frigate NVR never streams video footage directly to the internet. Home Assistant sends only small snapshots via LINE when events are detected. A notice must be posted informing all residents that AI cameras are in operation, and written consent must be obtained before installation under PDPA Article 19.
Camera comparison for HappySmart deployments: Reolink 510A (PoE, 5MP, 3,500 THB) suits living rooms and corridors; Reolink E1 Outdoor Pro (Wi-Fi, color night vision, 3,000 THB) suits front doors; Tapo C320WS (dual-band Wi-Fi, 1,500 THB) suits kitchens and zones needing coverage without high AI demands.
