    • A security system (10) suitable for use in monitoring property at an outdoor site that includes a portable housing (12) that supports a motion detector (14) for sensing motion within a detection zone. The security system further includes an ultrasonic transducer (74) and several alarm generators capable of repelling a human intruder, including a high intensity illumination source (18), high decibel siren (82), strobe light (19), and a speaker (78) for transmitting a prerecorded message. When an intrusion is initially detected by the motion detector, the ultrasonic transducer is activated to emit an ultrasonic signal that is irritating to nonhuman animals, thus clearing the detection zone of nonhuman intruders. If after sounding of the ultrasonic transducer motion is still detected, one or more of the alarms is activated. Additionally, an automatic telephone dialer (86) may be included in the system and activated by the system as another type of alarm, in response to detected intrusion. The system is integrated within the portable housing and is resistant to false alarms, making it suitable for use in monitoring property stored at an outside site. A method for utilizing the security system to protect property is also disclosed.
    • 一种安全系统(10),适用于在户外场所监测属性,包括便携式外壳(12),所述便携式外壳支撑用于感测检测区域内的运动的运动检测器(14)。 安全系统还包括超声波换能器(74)和能够排斥人类入侵者的多个报警发生器,包括高强度照明源(18),高分贝警号(82),闪光灯(19)和扬声器(78) )用于发送预先记录的消息。 当运动检测器最初检测到入侵时,超声波换能器被激活以发射刺激非人类动物的超声波信号,从而清除非人类入侵者的检测区域。 如果仍然检测到超声波换能器运动的声音之后,一个或多个报警被激活。 此外,响应于检测到的入侵,自动电话拨号器(86)可以被包括在系统中并被系统激活为另一种类型的警报。 该系统集成在便携式外壳内,防止误报,适用于监控外部存储的物品。 还公开了一种利用安全系统来保护财产的方法。
