The HbA1c (A1c) test measures how much glucose is attached to hemoglobin in red blood cells, reflecting average blood sugar over the past 8–12 weeks. It’s used to diagnose and monitor diabetes and prediabetes; diabetes is typically diagnosed at A1c ≥6.5% and prediabetes 5.7–6.4%. It’s not suitable for detecting short-term glucose changes, pregnancy, or certain hemoglobin variants.

The Ezviz H1c uses a wide-angle lens that provides roughly a 110° horizontal field of view (about 120° diagonal). This gives broad room coverage for monitoring a nursery or small room without frequent repositioning. Expect some edge distortion typical of wide lenses; digital zoom crops the image but does not expand the optical coverage.

Most EZVIZ cameras include built-in microphones and speakers for two-way audio, allowing live listening, speaking, and optional audio recording. Features vary by model—some offer noise reduction, audio alerts, and the ability to toggle audio in the app—so check the specific model’s specifications and settings to enable or disable audio and comply with local privacy laws.

Ezviz H4 pricing varies by model, region and retailer. Typical retail prices range approximately $120–$220 (roughly ₹10,000–₹18,000) for the standard H4; Pro or kit versions can cost more. Sales, bundles, and local taxes affect final cost—check reliable local retailers or the manufacturer’s store for current pricing and availability. Prices fluctuate frequently.

Normal HbA1c is generally <5.7% (below 39 mmol/mol) for children and adults. Prediabetes is 5.7–6.4% (39–46 mmol/mol); diabetes is ≥6.5% (≥48 mmol/mol). Glycaemic targets may be relaxed in older adults: healthy older people often aim <7.5% (58 mmol/mol); those with multiple comorbidities or limited life expectancy may have goals around <8–8.5% (64–70 mmol/mol). Individualize with your clinician.

Lower HbA1c by combining consistent lifestyle and medical measures: follow a balanced, portion-controlled diet low in refined carbs; exercise regularly (aerobic + resistance) and aim for weight loss if needed; take diabetes medications or insulin exactly as prescribed; monitor blood glucose and work with your care team; limit alcohol, quit smoking, manage stress and sleep, and attend regular check-ups.
