Bosch ISN-SM-50 Seismic Detector — Specs & Hong Kong Installation
Bosch ISN-SM-50 seismic detector for safes, strong rooms, and high-value enclosures in Hong Kong.
Best for: Safes, strong rooms, and high-value enclosures
Product overview
ISN-SM-50 processes attack patterns such as drilling, cutting, and impact on solid structures. Swan CCTV specifies it for jewellery, pharmacy, and cash-office enclosures where a window shock sensor would be the wrong tool.
Sensitivity is set to the structure — a thin partition and a steel safe need different thresholds.

Key features
- Detects drilling, cutting, and impact attacks
- Commercial-grade alternative to simple shock sensors
- Used on jewellery, pharmacy, and cash-office jobs
- Commissioned with sensitivity set to the structure type
- Professional supply and installation by Swan CCTV in Hong Kong
- Configured and tested on-site (not leave-in-box DIY)
- Documentation and user training included with installation packages
Compatibility
- Bosch intrusion panels with standard detector zone wiring
- Used with door contacts on the same enclosure
