Compliance & safety
Confirm regional SKU for firmware/feature differences (Hik‑Connect support, microSD limit, frame rates). Ensure installation by a qualified person and follow local electrical and data protection regulations. Verify power requirements for your unit — many listings indicate 12 V DC (not PoE) for this model; check regional datasheet if PoE is required.

Notes
Some spec details (sensor size, max microSD capacity, frame‑rate limits and Hik‑Connect behaviour) vary by regional SKU and firmware—refer to the Hikvision datasheet for your region/SKU before publication.
