I have noticed on rainy days that my floodlight will get triggered by the rain all night long , even when the floodlights been set to only turn on when motions been detected by the pir sensor and sensitivity to low
The IR emmiters are 4 little LED IR flashlights on the face of the V3 pumping out non-visible infrared light on two different wavelengths.
Since the V3 depends on an IR filter over the lens for it’s black and white night vision, it has to pump out this IR light to illuminate the field of view so that the cam picks up enough of the reflected IR light to render an image. It is the exact same concept as the LED flashbulb on your phone camera or the lights that photographers use… Except with non-visible spectrum IR light.
The problem arises when there is a Passive Infrared sensor that is designed to detect IR light. When enough objects (like rain, bugs, webs, fog, smoke) get close enough to the sensor reflecting all that IR light back, it is the mirror effect. The sensor is flooded with exactly that which is supposed to set it off.
Using active IR emmiters and passive IR sensors together is a delicate balance. It is an art to get them to the 90% solution. Add to that the relative inability to fine tune the IR emitter levels and it makes it more difficult. But, these settings are still a static combination in a dynamic environment. They cannot dynamically adjust to the 10% when the surrounding environment throws a curveball.
The problem is that if you shut off the emitters, your IR night vision will probably be extremely dark. But, it will confirm that the two are in conflict.
A Passive IR sensor, by design, is going to be overly sensitive in Active IR light. Everything in the field will be reflecting Active IR light back into the sensor. Changing the proximity of the IR light source will reduce that IR reflective sensitivity because it will not be as intense from a distance, but it will still increase the sensitivity of the PIR because everything in the field is bathed in IR light.
Changing the angle of the IR source would also be beneficial as to deflect the light rather than reflect it directly back to the PIR.
But, in the end, the PIR is doing exactly what it is designed to do when there is no IR source except for the heat emitting object moving in the sensor’s field.
You must just have yours in the perfect (or maybe worst?) conditions for this, as I and seems most others haven’t had these issues. Really any floodlight cam could have this issue, as there’s no way for an all in one device to prevent this.
Glad it’s working for you now though, your finally getting less cursed!
Many others experience this issue , constant false motion light activation
This is wrong , I have had the ring , eufy , and google floodlight cameras and all never had a single issue because they made the camera and pir sensor SEPARATE
Wyze engineered the floodlight pir sensor and the v3 together .
Which is why when I had my floodlight set to only turn on when motion is detected by the pir sensor my floodlights still kept getting triggered by rain droplets , spider webs , bugs , etc that cause a mirror effect bc of the ir lights . So turning off the ir lights helped reduce that over exposure . But I shouldn’t have to turn off the ir lights to reduce false motion lights activations as the camera and the pir sensor are engineered together ! I need night vision
I am glad that it worked for you and that there is still enough ambient visible light to use Color Night Vision.
I had the same struggle when I installed my V3 cams directly over 2 existing PIR ‘dumb’ floodlights. They battled each other in a constant on\off feedback loop all night.
I don’t think it is so much an issue of design as it is adjustment. I don’t know how the sensitivity adjustment on the Wyze PIR works as I don’t have one, but my lights have a 0-100 sensitivity dial so I was able to reduce my IR to low and dial my PIR lights back to about 25 for them to get along. It took over a week of adjustments to dial them in.
I would prefer to see a greater adjustment range in the cam IR emitters.
