![]() They’re capturing video on an ongoing basis, so when the pixels of that imagery change beyond a certain threshold, the camera detects movement. Smart home cameras detect movement a little differently. It also doesn’t use a lot of power since it’s simply receiving ambient heat, as opposed to systems like night vision cameras, which have to fire infrared light as well as receive it. The nice part about these passive infrared motion detection systems is that they won’t fire for just any movement – it has to be something that emits heat. This difference means movement, at which point the motion detector activates. If the infrared heat levels detected by each aren’t identical, it’s because something has moved into an area visible to one sensor, but not the other. Most motion sensors rely on a pyroelectric material that activates when it detects a change in temperature. Motion sensors work similarly, only with heat. When contact is made with more photons, it increases the electrical flow, which can then trigger actions. Photocells work with a resistor that changes its conductivity based on how many photons are hitting it. A motion sensor activates the light when it detects something moving within its field of view. What’s the difference between a photocell and a motion sensor?Ī photocell detects ambient light so lights turn on when it gets dark. Calibrate your motion detector to the correct angle and sensitivity.Turn on the power at the circuit breaker panel.Mount the motion sensor at the desired location.Feed the cabling back into its original location.Follow the instructions in your kit to connect the wires from your light’s power source to the motion sensor.Use a voltage tester to ensure the power is off.Remove the insert where the light meets the wall or other mount.Turn off the power to your light from the circuit breaker panel.If you aren’t using a socket adapter and will need to do the wiring, here are the general steps. Be sure to check the manufacturer’s instructions on specifics. ![]() Specific instructions for wiring up a motion sensor will vary by brand. How do you wire a motion sensor to an existing outdoor light? This socket adapter from Wyze is especially promising. It also means you don’t need to upgrade to smart lights to provide motion activation since the socket adapter handles the triggering. You don’t have to worry about handling any wiring. You would place the adapter between your current light bulb and your socket. The easiest way to install a new motion sensor to an existing outdoor light is to use a light socket adapter.
