FAAC J355 is a hydraulic retractable anti-ram bollard from FAAC Italy — capable of withstanding a 7.5-ton vehicle impact at 80km/h (K12 standard). Position: tier 1 perimeter security for embassy + government + critical infrastructure.
Use case flagship: (1) Embassy + consulate — front gate VIP + perimeter; (2) Government building — People's Committee, ministry HQ, courthouse; (3) Critical infrastructure — power plant, airport perimeter, military base; (4) Bank HQ + branch tier-1 — Vietcombank HQ, BIDV HQ; (5) Stadium + event venue VIP — Olympic-level security.
Differentiator vs fixed bollard (non-retractable): J355 retracts when vehicle access is needed (delivery, emergency, VIP convoy) — flexible perimeter. Civil work: pit depth 1500mm × 1000mm × 1000mm + concrete reinforced — install 3-5 days by civil contractor + 1-2 days commission by FAAC engineer. An Ninh Số has a project manager certified in perimeter security.

Câu hỏi thường gặp
- J355 vs fixed bollard: which one to choose?
Fixed bollard: fixed, cheap ($1-3K), does not allow vehicles to pass. J355 retract: flexible for VIP/delivery/emergency, 5-10x more expensive. Common pattern: J355 at main entry points (1-2 bollards) + fixed bollard around the perimeter (10-20 bollards) — cost-effective + flexibility combo.
- Is K12 rating necessary for Vietnamese banks?
K12 is for high threat levels (terrorism, organized crime ram-raid). Typical Vietnamese banks: K4 (1.5 tons @ 50km/h) is sufficient. K12 is only for HQ tier-1, embassy, government. It is recommended to consult with the local police PCC to accurately assess the threat level.
