Viewifi Turns WiFi Into a Camera-Free Motion Sensor

Field notes

Viewifi separates the system into a host device that remains in the monitored space and a user phone used to inspect events and control arming. The site lists Android, Linux, and Raspberry Pi hosts, with Telegram serving as the alert channel; each detection can include a signal graph and, when enabled, a photo or audio clip. Its free tier is described as supporting one host indefinitely, while Pro adds multiple hosts and routine-based anomaly detection.
