Most monitors report live pulse/heart rate and blood oxygen (SpO2). Depending on the model, they may also track movement (including abdominal movement), sleeping position or rollover, and temperature (skin or room temperature).

Ranges vary by model. Most devices list suitability for roughly 0–18 months, while one listing notes 0–12 months. For wearable sock-style monitors, a commonly specified weight range is about 6–30 lbs; one sock description lists use from about 1–18 months. Always check the manufacturer’s size guidance for a specific model.

Listed certifications include FDA clearance for the medical-grade sock monitor and various FCC and ASTM certifications for other devices; one camera has an independently verified cybersecurity mark. Data protection is described as using 256‑bit encryption and elliptic curve authentication.

Bundled camera systems offer high-definition (2K) streaming, a wide-angle lens (about 130°), and digital zoom (4x). They support dual-band Wi‑Fi for setup and streaming.

Most listings show battery power—commonly a single non‑standard lithium‑ion battery. Some models list mains (electric) power or a combination of battery and mains power.
