So I have no affiliation with the product nor the company but I bought one to test and was so pleased I bought a few more.
The Wyze cameras have great capability for night-vision but operate in a less than mainstream wavelength. I found some lights that barely emit any phantom glowing red on a random Amazon fishing expedition . They illuminate out to 50 yards with no issue and the only flaw seems to be they ship w/o a power supply lol.
Here are some images with NO visible lights on outside. The normal WyzeCams because they are mounted high above the field of view only show darkness even with IR turned on.
I believe I have the same ir illuminator. Works wonders. Noticed on your’s the illumination is concentrated very close creating a hotspot. I saw the same thing when my camera face and ir face were parallel. I have my ir light pointed upwards approx 30 degrees to broadcast the ir light at a different angle. This opened up the entire viewing image. Initially I could only see the ground. Tipped it upwards and the whole back of the house lit up. Found this out thru experimentation.
Where did you position these relevant to cams? I was looking for pics posters only showing before and after pictures not a picture of the position to cams or best means of mounting for achievable results.
