I have a mix of wired and wireless cameras, but at night I am noticing only on wireless cameras keep fogging up. This is a shot of my camera from light night and that blob in blue is me walking by the camera. I looked my the wired flood camera and wired spotlight camera and both where very clear. I am not sure if the wired camera let off more heat to reducing moisture build up, but I am wondering what can I do with my wireless camera to reduce mosture buildup? Thanks
That is a lot of fog on that lens @veener79 . I recommend checking the surrounding area for any causes that you might be able to avoid, such as dryer vents, heat exhaust, ac units, etc.
If this is happening merely due to a humid or moist environment/ climate, we have seen some neighbors use a water or fog repellent solution on the lens. Hope this helps!
