![]() ![]() Two main types of cameras use motion sensors. Instead, the camera uses the motion sensor to know when it needs to switch on a record. However – if you spot a camera with a motion sensor, the sensor isn’t using the camera to detect motion. It’s really important to make that distinction clear. Yes, you can buy a security camera that uses a motion sensor. Instead, the camera is using the motion sensor… Can You Buy A Motion Sensor With A Security Camera? That doesn’t mean you won’t ever see a camera next to a motion sensor.īut that’s not a camera that the motion sensor is using. How To Tell If A Motion Sensor Has A Camera?īecause motion sensors don’t use cameras, there’s no need to check whether they have one.Ī motion sensor is usually a pretty discrete object that is either attached to light or is situated close by, directed to look over a wide area from a high angle. It’s just a sensor that reads an area and is triggered when something changes. Instead, it looks for changes in infrared radiation typically caused by heat, such as our body heat. It’s passive, so it doesn’t emit anything. Most motion sensor lights use a PIR sensor – a passive infrared sensor. Instead, motion sensors rely on different kinds of radiation (which sounds scary, but it’s perfectly safe and normal). There are no cameras involved at any point. Active sensors ‘actively’ send out a signal, either to a separate receiver or a signal designed to bounce back to a receiver on the motion sensor. Passive sensors mean that they just detect things in their field of view. Motion sensors will use either a passive or an active sensor. Whether you can buy cameras with a motion sensor attachedĭo Motion Sensors Use Cameras To Detect Movement?.How to tell if a motion sensor has a camera.To make it a little bit clearer, let’s take a look at: Some cameras will have motion sensors attached, but the motion sensor works independently to control the camera. Depending on the type, they work using either a passive receptor or an active emitter (sometimes with a separate receiver). Instead, they notice changes in the radiation in their field of view. The ‘motion detector’ is a bit of a misnomer. Since they’re literally ‘detecting motion,’ then they have to be able to see the movement. If you don’t know much about motion sensors, you might assume they have to involve some kind of camera. ![]()
