Is the false alarm rate of vibrating optical cable high?

The working principle of vibrating optical cable is that after the intruder triggers, the pressure-sensitive membrane in the optical cable is deformed after being subjected to external pressure, and an electrical signal is generated, and whether to call the police is judged according to the size of the electrical signal. Therefore, Hangzhou Ruidun vibrating optical cable can work around the clock, free from the influence of sunlight, temperature, rain and fog, and the false alarm rate is very low!
