Assuming you don’t have pets, things like a cold draft, or incandescent lights turning on/off, or an insect flying in front of the sensor could all trip the sensor. Another possibility is an electrical fault of some sort, such that the sensor itself didn’t trip, but the alarm system thought the sensor did.
Can motion detectors go off for no reason?
Several factors can accidentally set off your motion sensors, including pets and any other activity from heat sources like vents, windows, stoves, or anything that causes a heat change near your sensor. The easiest way to test if your sensor is faulty is by putting a piece of paper in front of it for three days.
What can cause a motion sensor to false alarm?
What are some of the top causes of false alarms for motion sensors?
- Flying or crawling insects; spiders like to make homes in corners and anchor their webs to the sensors.
- Pets.
- Curtains or plants blown by air conditioning or heaters.
- Low batteries.
- Ceiling fans.
- Objects moving near motion sensors.
Why does my house alarm keep going off when it’s not set?
If a fault is present you may find your alarm going off (sirens sound) by itself, even if unset. This can happen for a number of reasons, including a dead battery or faulty sensor.
What sets off a motion sensor?
A motion detector sees movement, but it relies on what that movement is doing. Namely, changing light or shadow levels as they go by. Because the sensors rely on these movements, it’s possible that the way a tree is blowing in the wind and casting patterns on the carpet can be enough to set off a motion detector.
What is one of the most common causes of false alarms?
Approximately 80% of false alarms are caused by simple user error. Other common causes include installation mistakes and improper system maintenance.
Can dust set off a motion detector?
No, the dust particles shouldn’t really set off the motion sensor as it’s an IR type… But, the fact that you say the dust particles in the recording are “darting upward quickly” to me means that the camera may be in a heated air flow area. The heated air could/would set off the IR and turn the camera to record.
What triggers home alarms?
Unlocked or loose doors and windows: Door and window sensors are activated when the connection between the two sensors is disrupted. If a door or window is loose, it can easily be rattled by the wind and trigger an alarm.
Can wind set off a motion sensor?
In normal conditions, wind alone can’t set off the motion detector. Air doesn’t have an infrared heat signature, so the PIR won’t capture any movement with the wind blowing past. And basic movement sensors are based on light, so don’t see the invisible air particles’ movement.
How do you block motion sensors?
A quick solution that customers have said works well is to use black electrical tape to cover part of the sensor. Start by covering the edge of the sensor on the side you want to keep out of the detection area and use small pieces of tape to block it out.
How do I adjust the sensitivity on my motion detector?
Quote from Youtube video: To reduce the distance that the sensor will detect motion. Turn the sensitivity dial counterclockwise towards the mi N or minimum setting to increase the distance that the sensor will detect motion.
Can a house alarm go off by itself?
The two most common reasons an alarm will go off on its own are a dead battery or a faulty sensor. Additionally, a false threat such as a pet walking by can activate the sensor and cause the alarm to go off. Fortunately, all the above issues are easy to resolve using Boundary house alarms.
What do you do if your alarm goes off at night?

Can a spider set off house alarm?
Has your alarm triggered for no apparent reason? It may be you’ve been the victim of an 8 legged intruder – a giant spider. Actually, in reality, they don’t have to be huge to do this; all it takes is a spider to crawl directly over a sensor to fool it into thinking there’s some kind of intruder.
