Shameless thefts of boats and boat engines have become more common in Sweden. Ordinary actions to reduce the risk usually involves fences, surveillance cameras, night guards and patrolling security guards. The problem is that the water is left unsecured, which means intruders hidden by the darkness might enter unnoticed. Embsec vFence prevents this by immediately alarm if someone passes the virtual fence created by the laser sensor. The system can be aimed out over water and works regardless of lighting conditions. In wintertime the units are easily moved to monitor the hardstand. vFence is a series of laser sensors designed to work with modern network based surveillance systems. Power over ethernet and network alarms are standard, but the units can also switch relays for compatibility with analog alarm systems.

Instead of passive protection, such as a fences which are made to physically prevent trespassing, Embsec vFence products are used to detect people and objects in an area. If an intrusion occurs the unit immediately sends a network alarm to a server or alarm center. Network based alarm systems provides almost unlimited possibilities where alarm actions often include image capture, starting a siren or send silent alarms/notifications to guards.

Most perimeter system is based on standard photocell technology with one emitter unit and one receiver unit. Embsec's perimeter control is based on laser technology that doesn't need any reflector, making it possible to freely create alarm zones where needed. This makes it easier to set up the system and even makes it possible to set up virtual fences over water.

Application examples

Gate monitoring

Monitor all passages through gates, entrances or specific parts of a road - even with the vFence sensor is 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.


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.


Area surveillance

With a long range and high accuracy laser sensor in combination with fully adaptable alarm zones and alarm settings, the vFence S-500 laser scanner takes area surveillance to a new level. vFence S-500 is excellent for surveillance of large open areas such as industrial areas or water.


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.
