The 440 kV and 225 kV HV substations Henri-Paul are located in the village of Écuisses. The whole area is fenced and protected by Peridect. Invisible detection was one of the mandatory requirements of RTE, the operator of this substation. Great emphasis was put on elimination of nuisance alarms in conditions of close high-voltage transmission lines and high-speed TGV trains running close to the fence. Another requirement was integration with a camera system.

PERIDECT+ protects two data centres in Hungary. It is a perimeter protection of strategic importance. Sieza was asked to replace a dysfunctional competitive system that showed a huge amount of false alarms. During the technical inspection of the installation site we found that the fence consists of massive steel plates, which are often whipped by gusts of wind. It primarily caused all false alarms.

PERIDECT Perimeter Detection System protects several power plants in South Korea. Several systems were actually tested during the selection procedure. Great emphasis was placed on the elimination of false alarms and the simple and quick replacement of damaged components. Sieza Peridect proved the best performance from all tested solutions.

PERIDECT+ protects several fuel depots in Poland. It is a perimeter protection of strategic importance. The redundancy of the whole system was a mandatory requierment in this project. Sieza was the only manufacturer that met the specification. Ring connection with one control unit and two line controllers (master/slave) is used for system back up in case of detection line interruption or a short circuit.

A military checkpoint is a permanent feature where access by civilian visitors and vehicles is controlled by a military authority. One of the US forces bases in the United Kingdom receives dozens of visits a day at its checkpoint, and all cars are checked for unauthorized transport of people inside or out. The system they used so far did not work as the checkpoint guards expected. Detection of each vehicle lasted longer than 5 minutes and was unreliable with frequent jet flights over the object.

There is a small furniture production line in one of the Polish prisons. Material deliveries arrive through the checkpoint, finished furniture is then transported through the same checkpoint out. Every day dozens of cars pass through. Because there is a real risk that the prisoners will try to escape stored in the finished piece of furniture, a proper check of passing cars is caried out.

ŠKODA AUTO is a Czech car manufacturer founded in 1895 and currently belongs to the Volkswagen Group. There are several production plants in the Czech Republic. The plant in Mladá Boleslav produces Fabia, Octavia, Rapid, Scala models. The requirement was to secure 8,4km of perimeter and to interconnect the fence detection system with the existing CCTV system.

The Eurotunnel Calais Terminal is a railway terminal built for the transport of road-going vehicles on specially constructed trains through the Channel Tunnel. Sieza was asked in 2017 at the APS exhibition in Paris whether we could solve the fence protection in an environment with parasitic vibrations caused by passing trains. Our integration partner in France demonstrated during pilot tests that thanks to the unique detection algorithms, Peridect+ effectively eliminates all false alarms caused by passing trains.

Stockholm Bypass is a series of underground motorway tunnels between south and north of Stockholm. Most of this bypass, more than 17 out of 21 kilometres, is being built underground. The whole complex has several utility tunnels. One of them is protected by Bosch camera system and Sieza Peridect+ fence detection system. High demands were placed on the fence system. Specifically, it was necessary to install the system in winter when temperatures are below zero. The system should also support various types of fences.

The water plant Øyer is in a very isolated place and most of the time there are no workers. The customer did not feel that the security of the water power plant is good enough when there is only a fence around the facility. The requirement was a simple and trusted security solution that would detect if someone tried to enter the perimeter. The customer wanted a fence detection system that could be integrated into the existing control and monitoring system. Another mandatory requirement was to verify an alarm with an IP camera.
