Sometimes bugs or spiders that crawl across your lights’ sensors can even trigger your lights to turn on. Outdoor motion detection lights can be activated by passing cars, approaching visitors, or even rustling leaves in nearby trees. This would happen if your sensor is placed too close to a vent, and you can prevent this from happening by making sure you keep any sensors that are activated by temperature changes at least 15 feet away from vents. If your motion detector lights are activated by heat, your air conditioning and heating unit could even turn your lights on. Indoor motion detection lights can be activated by your family walking into a room or by your curtains fluttering in the wind. That is, after all, the purpose of having a motion detector light. The question of what sets off motion detector lights can be answered very straightforwardly: anything that moves can set them off. Do you want any slightest movement to activate the light, or would you rather have more movement trip it? This is something many homeowners must adjust until they find that sweet spot.ģ. The sensitivity setting on a motion sensor light refers to how much movement is required before a light goes off. You can change the setting depending on the device. If motion is detected but then motion stops, the light will turn off after a certain amount of minutes. Having more ambient lights near walkways and around porches will not only help friends to see where they are walking, but to deter burglars since they will be more easily seen. Ambient lighting could be smaller lights in less direct places, or even down on the ground. Ambient lights compliment the main lights by adding secondary lighting in places that the main lights don't cover. Ambient LightĪmbient light, or accent light, is something to consider when looking at outdoor safetly lighting. These modes may include a timer, which tells the light how long to stay on after detecting movement sensitivity, which adjusts how responsive the motion light is to motion and lux, which sets the light to turn on depending on how dark it is outside. Many motion sensor lights will have modes you can adjust depending on your preference. Of course, whether a motion detector light has any of these features will depend on the manufacturer, so be sure to check specifics before you buy. What are Common Features of Motion Detector Lights?īeyond the information shared in the previous question, there are other common features of motion detectors. This happens when the door or window they are fastened to is opened.Ģ. Usually placed on doors or windows, contact sensors activate when the direct signal from one part of the sensor to the other is interrupted. Contact Sensorsīased off of their name alone, it is pretty easy to figure out how contact sensors work. This type of motion detector light is usually used outdoors and is most often set to activate only when it is dark outside, like a front porch light. Light change detectors track ambient light and turn on your lights whenever they detect a big enough change in lighting. This type of sensor is great for both indoor and outdoor motion detector lights. Whenever something crosses in front of the sensor, it physically blocks the signal that the sensor is emitting, letting the lights know that there is movement and that it is time for them to turn on. Signal Blockage SensorsĪnother type of motion detection technology detects blocked signals. This type of motion sensor would be best utilized for an indoor motion detector light instead of an outdoor one. If the sensor detects a sudden change in temperature, like, say, a body, crossing in front of it, the lights will flip on. Some motion detection technology utilizes sensors to detect heat differences. Here’s a basic rundown of how each type of motion detection works in the context of motion detection lights. Whatever the type of sensor, motion detector lights use specialized technology to detect movement and turn on the lights. This means you already know how motion detector lights work, because the different technologies that power motion activated cameras are the exact same technologies that power motion detector lights. If you’ve read our page about motion activated cameras, then you are familiar with some of the different types of motion activated technology.
