- a thin wire is embedded in the form of an electrical conductor loop.
- the electrical conductor loop is often referred to as an alarm spider, since the formation of the electrical conductor loop resembles the shape of a spider web.
- the electrical conductor loop is traversed by a current. If the transparent disc device is destroyed by the action of force on the transparent disc device, then the first glass pane and / or the second glass pane will shatter / break, thereby destroying the electrical conductor loop and interrupting the circuit. As a result, an intruder alarm system provided on the security system is activated and an alarm is triggered.

- the invention is based on the object of improving a safety system of the prior art in such a way that, in the event of danger or imminent danger, an object to be protected and / or a person to be protected can be better protected the
- the security system according to the invention has at least one transparent pane device.

- the liquid crystal film is arranged on the transparent disk device and / or spaced from the transparent disk device.
- the distance of the liquid crystal film to the transparent disk device is a few millimeters, for example up to 15 mm.
- the distance of the liquid crystal film to the transparent disk device is a few centimeters, for example up to 15 cm, up to 30 cm or up to 50 cm.
- the invention is not limited to the aforementioned distances. Rather, any suitable distance between the transparent disk device and the liquid crystal film is usable.
- the transparent disk device and the liquid crystal film are arranged to each other so that the transparent
- the securing system has at least one sensor unit for emitting a sensor signal, wherein the sensor unit is arranged on the transparent pane device.
- the sensor unit is understood to be a unit which can detect physical properties, chemical properties and / or a material quality of the environment of the sensor unit qualitatively or quantitatively as a measured variable.

- the sensor unit is arranged directly on the transparent disc device. In other words, in this embodiment, the sensor unit is physically connected to the transparent disk device.
- the security system according to the invention has at least one control device for adjusting the transparency of the liquid-crystal film
- the control device is provided in particular for supplying the liquid-crystal film with a supply voltage which is used to align the liquid crystals. Accordingly, the sensor signal of the sensor unit of the control device is supplied. Depending on the sensor signal, the control device then selects the transparency of the liquid crystal film to be adjusted and accordingly controls the liquid crystal film.
- control device switches the liquid crystal film such that the liquid crystal film assumes the second transparency state.
- the liquid crystal film in the second transparency state, the liquid crystal film is opaque.
- the security system has the advantage that when a danger or an imminent danger is detected by the sensor unit, a sensor signal can be delivered to the control device such that the control device activates the liquid crystal film in such a way that the liquid crystal film becomes opaque.
- a sensor signal can be delivered to the control device such that the control device activates the liquid crystal film in such a way that the liquid crystal film becomes opaque.
- it is for example intended to switch off a control voltage (that is to say the supply voltage) of the liquid-crystal foil so that it becomes opaque.
- the viewing through the liquid crystal film is blocked in a space arranged behind the liquid crystal film and / or on an object located behind it. Accordingly, third parties are then prevented from viewing the object arranged behind the transparent pane device or the space arranged behind the transparent pane device. This increases the safety of, for example, people who are in the room.
- the invention is particularly suitable for the protection of persons and objects by bombardment or effects of blasting, especially splintering effects.
- the control device will drive the liquid crystal film in such a way that the liquid crystal film becomes opaque.
- the liquid crystal film is switched to an opaque state, for example, even when the sensor unit detects a failure of the general supply of the liquid crystal film with voltage.
- the circuit of the liquid crystal film in a security mode namely in the second transparency state in which the Liquid crystal film is opaque.
- the transparency of the liquid-crystal film can be brought into a desired state by operation of the control device, for example in the abovementioned first transparency state or in the abovementioned second transparency state.
- the control device has an input device with which a desired transparency state of the liquid crystal film can be adjusted. This is particularly advantageous when a user wants to be undisturbed and / or refuse from the outset the view into a room.
- the sensor unit may comprise any type of sensor. Hereinafter, some kinds of sensors which can be used in the invention will be explained.
- the sensor unit comprises at least one electrical conductor loop.
- the electrical conductor loop is designed as a thin wire.
- the electrical conductor loop has the shape of a spider web. The electrical conductor loop is traversed by a current. If the transparent disc device is destroyed by the action of force on the transparent disc device, then the electrical conductor loop is destroyed and the circuit is interrupted. As a result, the sensor signal is triggered and the liquid crystal film is driven by the control device such that it becomes opaque, for example.
- an alarm system provided on the security system is activated and an alarm is triggered.
- the sensor unit comprises at least one light sensor.
- the sensor unit comprises at least one light sensor.

- the control device controls the liquid crystal film immediately such that it becomes opaque, for example.
- an alarm system provided on the security system is activated and an alarm is triggered.
- the sensor unit comprises at least one vibration sensor.
- the vibration sensor is designed as an acceleration sensor.
- This exemplary embodiment has the advantage that upon the application of force to the transparent pane device, for example due to a bullet being shot and / or due to splinters of a blast, the sensor unit can detect it and emit the corresponding sensor signal to the control device.
- the control device in turn controls the liquid crystal film in such a way that the liquid crystal film, for example, becomes opaque.
