太阳能无线红外探测器 这种探测器在侵入者同时遮断上下4条光束时产生报警,否则不作反应,因此可排除小动物干扰。适用于寺庙、机场、车间等建筑物及周界警戒。警戒距离75米。当探测到异常时将426兆赫的电波发射给100米之外的接收机。在阴雨无日照的情况下可连续工作20天。由于采用无线方式,与有线相比具有降低布线成本、缩短工期的优点。 日本竹中工程公司产品。
Solar Wireless Infrared Detector This detector generates an alarm when the intruder intercepts the upper and lower 4 beams at the same time, otherwise it does not react, so it can eliminate the interference of small animals. For temples, airports, workshops and other buildings and perimeter alert. Watch out for a distance of 75 meters. When an anomaly is detected, a 426 MHz radio wave is transmitted to a receiver 100 meters away. Continuous rainy days in the case of non-working 20 days. As a result of the wireless way, compared with the wired lower wiring costs, shorten the duration of the advantages. Japan Takenaka Engineering Company products.
