When a storm hits the city, when a typhoon lands on the coast, when dust storms sweep construction sites in the northwest — is your access control still running reliably? Outdoor access is never as simple as "installing indoor equipment outside". With full-scene waterproof coverage as its product strategy, Vguang builds a graded protection matrix from IP65 to IP67 so every terminal runs reliably in the harshest environments.
Understanding IP Protection Ratings
Higher is not always better — matching the scenario is what matters
IP ratings (IEC 60529) consist of two digits: the first indicates dust resistance and the second water resistance. For outdoor access devices, the three common ratings each have clear application boundaries.
| Rating | Dust Resistance | Water Resistance | Typical Test Conditions | Applicable Scenarios |
|---|---|---|---|---|
| IP67 | Dust-tight | Protection against temporary immersion | No water ingress after 30 min immersion in 1 m fresh water | Basement flooding areas, exposed turnstiles, rail transit, flood-prone points |
| IP66 | Dust-tight | Protection against powerful water jets | Powerful jets from any direction at 100 L/min for ≥3 min | Exposed outdoor areas, coastal typhoon zones, high-pressure washing areas |
| IP65 | Dust-tight | Protection against low-pressure water jets | Low-pressure jets from any direction at 12.5 L/min for ≥3 min | Under eaves, semi-outdoor passages, sheltered entrances |
Key insight: IP65 withstands "rain", IP66 handles "heavy rain + high-pressure washing", and IP67 copes with "temporary submersion". Higher ratings are not always better — paying IP67 cost to install under an eave is over-engineering, while exposing IP65 devices to typhoon zones is under-spec. Matching the rating to the scenario is true engineering thinking.
Vguang Waterproof Product Matrix
Five levels of coverage, from scanning to face recognition across all scenarios
Vguang’s waterproof line covers QR scanners and face recognition terminals with IP67, IP66 and IP65 ratings precisely matched to different outdoor scenarios.
Validated in Real Scenarios
From metro to construction sites, from coast to desert
The reliability of Vguang waterproof terminals is not a paper parameter from the lab but an engineering fact repeatedly verified across thousands of projects nationwide and overseas.
Full-Chain Sealing Engineering Philosophy
Four design principles behind Vguang’s waterproof capability
Reaching an IP rating is not about simply "tightening the housing" but about full-chain engineering from structural design to material selection. The reliability of Vguang waterproof terminals rests on four design principles:
- 1Integrated Structural Design — One-piece die-cast housings minimize seams; key interfaces use double protection of sealing rings and potting compound to eliminate water ingress paths at the source.
- 2Material-Level Corrosion Resistance — Anti-corrosion metal housings with special surface coatings resist salt spray, acid and alkali; PCB boards get conformal coating so even trace moisture cannot harm the circuitry.
- 3Rigorous Environmental Testing — Every waterproof terminal passes IP rating tests, high/low temperature cycling, salt spray and vibration testing before shipment, ensuring lab parameters equal on-site performance.
- 4Wide-Temperature Operation — Outdoor environments bring not only water but extreme temperatures. Vguang waterproof terminals support -30℃ to 70℃ operation, staying online from northeastern winters to Turpan summers.
Full-Scene Waterproof Coverage
So no journey is ever interrupted by weather
The essence of an access control system is the balance of security and efficiency. A face terminal that fails in a storm brings not just repair costs, but congested access, security gaps and broken user experience.
With full-scene waterproof coverage as its promise, Vguang builds a graded protection matrix from IP65 to IP67: IP67 Q340 / JL7066 are the "divers" of scanners, IP66 VF105 / VF107 are the "storm warriors" of face terminals, and IP65 VF203 is the "value king" of semi-outdoor scenarios.
Whether your project is a community in the southern rainy season, a site in northern sandstorms, an industrial park on the typhoon coast or an underground metro entrance — Vguang has a precisely matched waterproof terminal to keep access running, rain or shine.
