Brands to Avoid: Alpha, Yingshuo, Niu, and Jingzhang—these lack their own factories (often relying on contract manufacturers) and are heavily promoted by influencers with exaggerated spec claims; they often lack even basic security lock cylinders. Also, avoid rebadged products from Haier, TCL, or Lenovo (prone to jamming over time) and generic “no-name” brands.
Look for these details: Class C security lock cylinders; recognition technologies (facial, fingerprint, finger vein, palm vein); dual-lithium battery life; surveillance/snapshot capabilities;
and smart home ecosystem integration (e.g., Mi Home). Selection Guide: Choose based on needs (Facial: Kaadas, EZVIZ; Palm Vein: EZVIZ, Imou; Value: Xiaomi, Imou, VOC; High-end: Dessmann; Avoid: Alpha, Yingshuo, Niu, Jingzhang).
