Try using 2 layers of black electrical tape to cover the black area around the lens of the WyzeCam. We tried cloth tape for lower reflection, IR light bleeds through, we also tried a single layer of black electrical tape, IR light also bleeds through. That is 3M black cloth and electrical tape, They are currently working on this in beta and you will soon be able to turn off the Infra-Red or IR lights around the camera lens and still leave the camera in night vision mode with the app. Until then, when the new app is released this is what we had to do with 5 Wyzecam v2’s. We put a single strip down each side vertically, one on top of the other along the face of the camera! We are also adding both daylight floods and IR flood lights around the building which seem to be more effective since there are fewer insect events and more IR lighting coverage in the areas we specifically want lighted by IR at night. Thus the IR light is not directly in front of the cameras and fewer insect fly-by false events occur. Also, I do not recommend trying to cut the tape on the face of the cameras, cut the tape first, then install it on the camera. The closer to the glass, or flat against the glass, the less reflection you will see. If you place the camera firmly against the glass the black tape acts as a sort of seal against the glass and seems to prevent reflection. If you look closely at the photo you can see how is has this effect. If you could find a black rubber O ring to fit the camera’s lens and to seal the camera against the glass, the camera’s internal IR lighting could possibly be left on without reflection if it was sealed directly and firmly against the glass?
Hope this helps,
