Usage recommendations

Install the camera at a height that balances wide coverage and facial recognition needs (typically 2.5–4 meters). For best low-light results, avoid direct bright light sources facing the lens and use complementary lighting if required. Regularly check firmware updates and maintain a secure network configuration to ensure reliable operation and protection against unauthorized access.
