I. Main Types of Safes

1. Home Safes
   • Purpose: Store cash, jewelry, documents, and other valuables.
   • Features: Compact size (typically 30–100L), fireproof or anti-theft designs, some support wall-embedded installation.
   • Price Range: ¥500–¥3,000.
2. Commercial Safes
   • Purpose: Used by businesses to store invoices, contracts, cash, etc.
   • Features: Larger capacity (100–500L), often equipped with dual locks or electronic keypads; some support multi-user access control.
3. Fireproof Safes
   • Key Function: Withstand 1–2 hours of extreme heat (≥800°C), ideal for paper documents.
4. Burglary-Resistant Safes
   • Certifications: Compliant with CSP (China Security Product) or European EN1143 standards; steel plate thickness ≥6mm.
5. Portable Safes
   • Use Case: Travel or temporary storage; lightweight (<5kg) with password/fingerprint locks.

II. Key Factors for Choosing a Safe

1. Security Level
   • Check certifications (e.g., CSP, UL). Anti-theft safes should have drill-/pry-resistant locks.
   • For fireproof safes, prioritize insulation materials (e.g., ceramic fiber).
2. Installation Method
   • Fixed: Bolted to floors/walls for enhanced security.
   • Portable: Flexible but opt for heavier models (≥50kg to deter theft).
3. Lock Mechanisms
   • Mechanical Locks: Reliable but less convenient.
   • Electronic Keypads: User-friendly; require regular battery replacement.
   • Biometric Locks (fingerprint/facial): High convenience but costly.
4. Size & Capacity
   • Choose based on item volume, leaving 20% spare space for future needs.

III. Usage & Maintenance Tips

1. Installation Location
   • Avoid damp/hot areas (e.g., basements, kitchens). Fireproof safes should be kept away from open flames.
   • Concealed placement (e.g., inside closets) reduces theft risks.
2. Regular Checks
   • Replace electronic lock batteries every 6 months; lubricate mechanical locks periodically.
   • Inspect anchoring bolts for looseness.
3. Emergency Measures
   • Forgotten passwords: Use backup keys or contact the manufacturer (proof of purchase required).
