The Nestling Caregiver Pager is an onsite safety appliance utilizing Amplitude Shift Keying (ASK) modulation on the 433.92 MHz sub-GHz band. This localized RF system bypasses Wi-Fi network congestion, ensuring high signal fidelity for medical alert applications. The transmitter buttons carry an IP55 rating for protection against liquid ingress, though the mechanical membrane switches have a finite lifespan of approximately 50,000 activations.
Hardware specifications indicate that the receiver is a plug-in AC unit that occupies a standard wall outlet. The transmitters are powered by CR2032 batteries with an estimated operational life of 6 to 12 months. Because the system is strictly point-to-point, it does not support remote smartphone notifications or digital event logging.
Performance metrics demonstrate superior wall penetration compared to 2.4GHz devices, although the system is limited to audible alerts. The receiver must be placed centrally to ensure the acoustic footprint covers the required area of the floor plan.
- Frequency: 433.92 MHz
- Transmitter Battery: CR2032
- Protection Rating: IP55 (Buttons)
This system is ideal for scenarios requiring a "dumb" hardware solution with no subscription fees or privacy-related cloud dependencies.
The Calltou Wireless Call Button System is a comparable alternative that utilizes similar 433MHz chipsets with a focus on button membrane longevity.
This appliance is classified as part of the wireless sirens and panic buttons hardware class.
