Staying safe in your home is important. Because of this, many people want to make sure their security system offers multiple layers of protection. Motion detectors are a key component of many modern home security systems. They often work as a supplement to door and window sensors. They can also help determine if someone is cutting through or near your yard at night. But do motion detectors work through windows? The answer isn’t a simple yes or no. Several factors come into play, including
- Whether motion detectors are meant to activate lights only or an alarm
- The clarity of the glass in your windows
- The sophistication of your motion detectors
How Motion Detecting Lights and Alarms Work Together
One of the most common uses of motion detection is with the automatic doors at the grocery store. A motion detector senses when someone is approaching and opens the door. Similar sensors can also trigger an alarm.
But not all motion around your home is necessarily alarming. How do you determine the difference between a bunny hopping across the yard and a potential intruder?
Security systems have a more passive system that looks for infrared energy. This is a type of heat detection, that is normally calibrated to detect a human and ignore animals. Infrared light isn’t detected by the human eye, so it doesn’t add light to your yard. Some systems use outdoor cameras, which may be motion activated. Others place the cameras indoors where it is harder for a potential intruder to tamper with them.
There can be an issue with this because the glass from the window can cause blurriness or other distortion to images caught on the camera. You may be able to tell there was a person near your entrance, but the image may not be clear enough to provide any identifying information.
Proper Light Support Makes for Better Security
One common problem with infrared cameras that are self-installed is that they need other light support in order to provide their best security. The images captured by cameras when it is very dark are rarely clear. You may be able to tell that the intruder was human, but not much else. This doesn’t give authorities much to go on in the case of a robbery or another crime.
If an intruder notices an outside camera, they may do their best to avoid it, but if it can work from inside, on the other side of a window, it may keep the camera more secure. For this to work, exterior lighting is a must to ensure that images taken from inside the window are clear. Whether your camera’s motion detector will work through the window is irrelevant if your camera can’t capture a good image. If the excess light annoys the neighbors, of if you worry about using too much electricity, it may help to use motion-activated lights. The surprise of a light coming on may be enough to deter some intruders, especially if the lights are floodlights.
You can also increase clarity on a video by turning off infrared lights and shooting the video in monochrome. A grayscale image actually provides more discernable detail than color. Angling the camera helps too, as well as keeping it as close to the glass as possible.
