Fill the room with fog. Leave them nothing to take.
Density® Basic is the entry-level fog generator for homes and small shops — dense, non-toxic fog that floods up to 390 m³ and sends intruders out empty-handed.
An alarm tells you it happened. Fog stops it happening.
A typical break-in is over in two to three minutes — long before anyone can respond. Security fog removes the one thing a thief needs: visibility.
Your alarm, a sensor or a panic input fires the unit.
Once armed, the Basic floods the room with non-toxic fog the moment it’s triggered.
The intruder can’t see the goods, the exit, or their own hands.
Nothing to grab, nowhere to go. Most intruders abandon within seconds.
of theft attempts at fog-protected sites are stopped. A break-in is usually over in under two minutes — fog closes that gap in seconds, where an alarm only raises it.
