Notification unit, warning system and method for operating a warning system

A notification unit comprising:

• at least one motion sensor, which detects movements of objects in the environment of the notification unit, and at least one signal device which is suitable for outputting different optical or acoustic signals,
• wherein the type of the different optical or acoustic signals depends on whether the motion sensor has detected a movement of an object in the environment of the notification unit,
• wherein the notification unit is at least partially formed as a column defining a cavity with a first end and a second end and wherein functional components of the notification unit are disposed in the cavity,
• wherein a mechanical interface is provided at the first end of the column for coupling the column to a carrier,
• wherein the carrier is a tripod with three feet,
• wherein an anchoring device is provided for at least one of the feet,
• wherein the anchoring device has a first base plate to be disposed parallel to the ground and a second leg plate to be disposed parallel to the leg,
• wherein the base plate and the leg plate are pivotably connected to one another via a pivot axis.

A warning system comprising:

• a notification unit comprising:
• at least one motion sensor, which detects movements of objects in the environment of the notification unit, and at least one signal device which is suitable for outputting different optical or acoustic signals,
• wherein the type of the different optical or acoustic signals depends on whether the motion sensor has detected a movement of an object in the environment of the notification unit,
• wherein the notification unit is at least partially formed as a column defining a cavity with a first end and a second end and wherein functional components of the notification unit are disposed in the cavity, and
• a central unit which is suitable for receiving a signal sent via radio from the at least one notification unit and to then output a notification to a user of the central unit.

A method for operating a warning system, the warning system comprising

• a notification unit comprising:
• at least one motion sensor, which detects movements of objects in the environment of the notification unit, and at least one signal device which is suitable for outputting different optical or acoustic signals,
• wherein the type of the different optical or acoustic signals depends on whether the motion sensor has detected a movement of an object in the environment of the notification unit,
• wherein the notification unit is at least partially formed as a column defining a cavity with a first end and a second end and wherein functional components of the notification unit are disposed in the cavity,
• a central unit which is suitable for receiving a signal sent via radio from the at least one notification unit and to then output a notification to a user of the central unit;
• the method comprising the steps of:
• optically monitoring a monitoring area,
• detecting a critical object and a location of the critical object in the monitoring area,
• activating a first alarm through the and at the notification unit,
• detecting a critical location change of the object, and
• activating a second alarm, which is different from the first alarm, through the and at the notification unit.
