FAQs
Q: What’s the main difference between the DS‑2TD2628‑3/QA and DS‑2TD2617‑3/QA? A: The DS‑2TD2628‑3/QA offers higher thermal resolution (256×192 vs 160×120), finer pixel pitch (12 µm vs 17 µm), and deep‑learning VCA classification beyond basic perimeter rules.
Q: What is the temperature measurement accuracy? A: Both models offer –20 °C to 150 °C range with ± 8 °C accuracy.
Q: Are smoke and sun‑reflection alarms supported? A: Yes on DS‑2TD2628‑3/QA. The DS‑2TD2617‑3/QA supports smoking detection and sun‑reflection filter but does not include vehicle/human classification algorithms.
Q: How long is the thermal detector guaranteed? A: Hikvision offers a 10‑year guarantee on both detectors.
