There is a counter-device for every unit. This pocket device offers very good services. Night observation by camera or night vision instruments with IR light can be easily detected. Furthermore, even laser interception devices with strong beam within the invisible 880 nm range can quickly be located. You simply have to put the unit with its sensor into the direction where you suspect an observation device. If the IRbeam meets the sensor a visual and/or acoustic alarm will be heard. Its distance can be evaluated according to the alarm, which is strong at short distances and weaker at longer distances.
