No there really isn’t. Window glass reflect the IR light emitted by the camera. If you have lots of lighting outside, you can try turning off night vision, which will also turn off the IR LEDs. If there’s enough light outside, you may get a usable image.
There have been many requests for Wyze to provide the ability to turn off the IR LEDs while leaving night vision enabled so people can use their own IR floodlights mounted outside. No word on when or if Wyze is planning to implement this.
Some people have reported success with taping over the IR LEDs which can see as red dots visible in the black part of the front of the camera when night vision is on. You may want to try this.
