Powerful protection for large premises. Leave intruders with nothing.
Density® 2400 is the high-performance fog generator for large business premises and high-risk sites — fast, dense fog that floods up to 2,400 m³ to zero vision 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 2400 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.
