Why would a leading national authority in construction standards and technical expertise, such as the Ministry of Construction (Bộ Xây dựng), choose OSUNO smart locks? Which models successfully passed stringent certification and inspection processes to secure the most authoritative leadership rooms? Beyond mere security, these locks represent a symbol of prestige, modernity, and technological leadership. Below, we take you behind the scenes of the recent installation at the Ministry headquarters and reveal the compelling appeal of the powerful duo: OSN-3325 and OSN-3358.
1. OSN-3325 Electronic Lock with App Unlock: The “National Favorite” for Ministry Offices
The OSN-3325 model was deployed by the OSUNO technical team in specialized working rooms throughout the Ministry of Construction. This robust electronic lock is engineered for high-frequency daily use while maintaining a refined and professional appearance.

Key Advantages of the OSN-3325:
- Semiconductor Fingerprint Technology: Ultra-sensitive vein recognition with 100% anti-forgery protection, ensuring maximum security for confidential departments.
- Versatile Unlocking Methods: Combines fingerprint, password, RFID card, and emergency mechanical key — offering flexible access for staff at all levels.
- Optimized for Wooden Doors: Sleek and sturdy design, perfectly suited to the classic wooden office doors commonly found in government agencies.
- Exceptional Longevity: Premium alloy construction, highly resistant to scratches and impacts, ensuring the lock remains pristine and reliable over years of use.
This model has established itself as a dependable, cost-effective solution for high-traffic professional environments, backed by EI70 fire-resistance certification — a mandatory requirement for government facilities.
2. OSN-3358 Fingerprint Door Lock with App Management and Remote Access
While the OSN-3325 excels in everyday office durability, the OSN-3358 (including the Plus variant) is the preferred choice for high-level executive suites, thanks to its intelligent automation and forward-looking design.

Why the OSN-3358 Is Ideal for Leadership Offices:
- Fully Automatic Locking Mechanism: The most distinctive feature — simply close the door and the deadbolts automatically extend to secure the room. No need to manually turn the handle, guaranteeing consistent protection whenever the leader steps out or receives visitors.
- WiFi/Bluetooth App Management: Leaders can monitor entry/exit history directly on their smartphone. Key features include issuing temporary access codes or remote unlocking — extremely practical for assistants or authorized personnel when the leader is absent.
- Advanced Live-Scan Fingerprint Technology: Reliable recognition even with dry hands or for elderly users with less distinct fingerprints.
- Premium Aesthetics: Elegant curved design with luxurious finishes, adding a sophisticated and prestigious touch to executive spaces.
This model supports remote control, app-based management over unlimited distance (via WiFi gateway), and long-lasting rechargeable lithium batteries for maximum convenience.
3. Why Do Leading State Agencies Consistently Trust OSUNO?
The Ministry of Construction’s decision to choose OSUNO over imported brands is far from coincidental. It reflects years of proven quality validation:
- Trusted Domestic Brand: OSUNO fully masters its own technology, enabling tailored solutions that precisely meet the unique requirements of each project.
- Rigorous Certifications: Compliant with EI70 fire-resistance standards mandated by the Ministry of Public Security — a critical requirement for major government buildings.
- Lightning-Fast After-Sales Service: Nationwide network covering 63 provinces and cities, with technical response guaranteed within 2 hours — a level of responsiveness that imported brands often cannot match.
This high-profile project at the Ministry of Construction serves as the strongest testament to OSUNO’s quality, reliability, and suitability for critical national facilities.
