Wireless SOS Call Button Elderly Care

A purpose-built wireless alert system for personal emergency response: includes a portable, splash-proof call button (2.4 x 1.6 x 0.8 in, 2.1 oz) and a plug-in receiver with AC power + battery backup. Operates on 433 MHz RF band for interference-free performance. Range: up to 1000 ft outdoors, approx. 500 ft indoors. Features 52 melodies, five-level volume (0–110 dB), and LED-only silent alert. Transmitter is splash-resistant — appropriate for dry-area bathroom mounting (e.g., beside sink or toilet), but must be removed before bathing or showering. Powered by CR2032 battery (transmitter); receiver draws from mains with fail-safe backup. No internet, app, or recurring fees required. Used daily by families supporting ageing parents, adults with disabilities, and individuals recovering from surgery or illness. Enables help-seeking without shouting, climbing stairs, or navigating complex interfaces — promoting dignity, autonomy and timely intervention. Validated for use in UK domestic, community and regulated care contexts — meeting baseline technical and safety expectations for assistive alerting devices.
