Solar security lights are the ideal protection for households and properties. They help to discourage burglars and intruders. These solar security lights, also called solar motion detector lights, contain passive infrared motion detectors which are mainly designed to sense any body heat generated by humans and animals. Such solar security lights also monitor surrounding areas and automatically trigger on the lights when any motion is detected. Most of these solar security lights have options to adjust the sensitivity and sensor angles also. One must make use of these settings so as to fine tune the lights so that a stray dog on the property would not set off the alarm.
