In challenging weather conditions, a weather alarm is sent to the VMS system while the sensor effectively filters out the weather noise and thus eliminates false alarms.

"A year ago we launched the laser sensor Vfence F-501, an IP based detector for outdoor use with long range and high accuracy. The new version has a newly developed algorithm that both makes the installation easier and allows for more reliable detection. Avoiding false alarms has been our main objective," says Erik Lindstein, CEO of Embsec.

Vfence F-501 uses an adaptive algorithm which automatically adjusts the object detection sensitivity based on signal stability. This allows the sensor to maintain maximum detection while suppressing noise from fog and snow or other disturbances such as birds and falling leaves.

The Vfence F-501 evaluates the measurement signal in real time to determine the weather intensity at a scale from 0 to 10, allowing the user to easily create weather alarm response actions. Weather alarms to a VMS system can be activated when the weather intensity exceeds a particular threshold.

"Embsec's new self awareness functionality further improves on our detection capability and low false alarm rates in difficult weather conditions. Operators are notified when there is a risk of limited detection capability, a feature that we have not seen in any other products on the market, this makes Vence F-501 unique," concludes Erik Lindstein.
