Wireless SOS Call Button System

This wireless caregiver pager system consists of a portable transmitter (SOS button) and a receiver pager. The transmitter measures approximately 6.5 x 4.5 x 2 cm and weighs around 45 g; the receiver is similarly compact and lightweight. It operates on 3 x AAA batteries (not included in receiver). The system uses reliable 433 MHz wireless technology with up to 500 feet (approx. 152 m) signal range — penetrating up to 2–3 floors effectively. Both units are constructed from durable white plastic. Designed for straightforward elderly monitoring, it delivers immediate alert transmission upon button press without delay or pairing complexity. The system enables real-time assistance requests: pressing the SOS button sends an instant wireless signal to the pager, triggering audible and visual alerts. There is no app, subscription, or Wi-Fi dependency — just plug-and-play operation. Ideal for home use where mobility, simplicity and reliability are essential. Use cases include overnight monitoring in multi-level homes, post-operative recovery support, dementia care supervision, and independent living setups where rapid response to falls or distress is critical. Especially suited for caregivers managing multiple responsibilities while needing dependable remote awareness.
