Start with reliable contact sensors on exterior doors and windows, including tilt sensors for garage doors. Pair them with tamper detection and clear chimes, so everyday openings are acknowledged without panic. Group sensors by zones—front, side, upper floor—to understand movement patterns. If a window sensor triggers while everyone is away and no expected delivery is scheduled, escalate quietly first with lights and a camera snapshot, then act decisively if corroborated.
Prefer dual‑technology motion sensors or well‑placed PIR units with pet immunity. Tune sensitivity based on room usage and time of day. Motion at the foyer after midnight may demand attention; motion in the living room at 5 p.m. might simply confirm occupancy. Pair motion with ambient light sensors to avoid unnecessary lighting, and use delay timers that align with real behaviors. Let overlapping signals confirm authenticity before alarms escalate.
Choose focal lengths that match distances, and aim for faces at entry height, plates at the driveway, and wide coverage where needed. WDR helps in bright scenes, and IR or color night vision supports darker areas. Mount cameras at thoughtful angles to reduce glare and prevent easy tampering. A single well‑placed device often beats three poorly positioned ones, saving bandwidth, storage, and review time when seconds matter most.
Use person, vehicle, and package detection to cut false alerts. Prefer local AI when available to reduce cloud dependence and preserve privacy. Create virtual tripwires for driveways and line‑crossing rules near gates. If your camera recognizes familiar faces with consent, build gentle automations like welcome lights rather than alerts. Regularly review notifications; a monthly tuning session can transform a noisy system into a calm, trustworthy assistant.
