ELRO ARD51 Range

The radar sensor has an adjustable range of 9 to 16 metres. This means that you can set the sensor to detect movement within a radius of at least 9 meters to a maximum of 16 meters from the device. This flexibility allows you to optimally configure the sensor according to the specific requirements of your application. For example, if you want to monitor a smaller area, you can set the sensor to a shorter distance. For larger surveillance areas, the range can be increased to the maximum accordingly. In this way, the ELRO ARD51 offers a tailor-made solution for different safety requirements and helps effectively deter unwanted guests.

Power supply options for the ELRO ARD51

The ELRO ARD51 can be powered by batteries, although these are not included. This makes the device portable and independent of a socket, which is convenient when there is no power supply nearby.

In addition to batteries, the ELRO ARD51 can also be operated with the included adapter. The adapter has a cable length of 1.5 meters, which makes it easy to connect to a power source. This is convenient for long-term use without worrying about replacing the batteries.

Distance Adjustment

With the ELRO ARD51 electronic guard dog, you can adjust the detection distance according to your needs. In the battery compartment there is a small switch that allows you to adjust the range of the radar sensor. By moving the switch, you can vary the distance from at least 9 metres to a maximum of 16 metres. This gives you the flexibility to adapt the sensor to the specific needs of your environment, whether for monitoring a small area or larger area.
