Wide range of uses - The sensor proves not only to protect the room from intruders, so you don't have to look at it only from the point of view of safety. You can also successfully use it as a whistleblower when a customer enters a store, you can place it in a place that children should not enter while playing, or you can set it up at the entrance of a warehouse to inform about an approaching vehicle.
Motion sensor - The motion sensor integrated into the device continuously scans the entire room for any sign of movement. It emits an infrared light beam invisible to the human eye and awaits abnormal feedback. If the feedback is different from the other signals sent by the sensor, a siren is activated and the sensor emits a signal.
Loud Alarm - A built-in loud alarm siren ensures a reasonable noise level when motion is detected in the room. When the siren is activated, one of the 30 available melodies sounds from the detector, which you can set in advance. The sound is so loud that it is easy to hear from a distance of several metres or from another room. You no longer have to constantly look into the next room to see if someone is there.
Increases safety - A loud motion sensor with built-in siren gives you more control over access to the rooms where it is attached. You can attach it to the wall with bolts or simply place it on a flat surface and enjoy more safety. When the sensor detects movement, the device emits a loud beep to alert you to the danger.
High-quality materials - This sensor is made entirely of high-quality plastic, which is very resistant to mechanical damage. The sensor is in a very minimalist style, so it will fit perfectly into any room. From the guest room, to the kitchen, office, warehouse, workshop or garage. If you need to control the neighboring room every now and then, then choose this sensor and relax.
