FLEX_Sense 2
Flex sensors for railingsFLEX_Sense 2 detects climbing on solid railings. It doesn’t listen for noise or measure vibration. It measures the metal structure itself.
The operating principle.
High-precision sensors are fitted at the bases of the railing, typically every 2 m. Anyone climbing applies a force that bends the railing very slightly. The bend can’t be seen, but the sensors measure it.
Detection starts in the first moments of the attempt, even if no noise is made.
The FS2 analyzer has a display and buttons. Setup and suitability testing are done on site, without a laptop. For the test, one sensor with clamps and an analyzer with a 9 V battery are enough.
Typical applications
- Detached houses and villas
- Offices, government buildings, embassies
- Hotels and resorts
- Schools and universities
What you get with FLEX_Sense 2.
Measures the structure
It detects the railing bending, not noise or movement in the space around it.
Always on
Works 24 hours a day, with no arming or disarming.
Shrubs and branches
Vegetation touching the railing doesn’t prevent detection.
Self-protection
It alerts if the cable is cut or a sensor is unscrewed.
On-site setup
OLED display, menus and a real-time graph of the response.
Key specifications.
Full details in the datasheet.
On buildings with a railing at the front and a wall at the back, FLEX_Sense 2 and CLIMB_Sense 2 cover the whole perimeter. SUB_Sense 2 guards the entrance.
