Perimeter control

Embsec vFence technology makes it possible to monitor and locate intrusions for applications where physical fences not are desirable, possible or where enhanced security is required. The laser sensors works without reflectors and reacts in fractions of a second.


Gate monitoring

Monitor all passages through gates, entrances or specific parts of a road - even with the vFence sensor placed several hundred meters away. Create alarm zones freely to make sure the system only set of the alarm when an object is detected at the desired location.


Vehicle monitoring

vFence F-501 is easily set up to detect if a vehicle is moved. Even if the system is placed several hundred meters away from the vehicle, the sensor instantly alarms when a movement of the current vehicle occurs while all other objects in the area are ignored.


Boat detection

Detect all boats entering or leaving the harbour and reduce the risk of boat and engine thefts, regardless of light conditions and weather. Embsec vFence products are designed to cope with harsh marine environments. Since the sensor works without reflectors it is possible to create virtual fences over open water.



vFence F-501 can be mounted on a tripod and moved as needed, to ensure fast and accurate operation in exposed locations. Surveillance can be done remotely and no camera permissions are required.


Stake-out operations

vFence F-501 makes it possible to create a detailed log of visitors entering or leaving a building or to send alarms at any activity, fully automatic and at a distance up to 500 meters. No camera permission is needed since the sensor utilize eye-safe laser technology.
