I have lots of security cameras and they all make a click sound when the IR cut filter switches on or off. The Wyze Cam records and streams audio, which is great, but the “Click!” of the filter comes through the audio. When I use the camera as a baby monitor on a partly cloudy afternoon with the shades drawn, it’s just the perfect light level for the camera to switch back and forth between day and night mode with every passing cloud. If I’m trying to take a nap in another room at the same time as my child, the “click!” sound wakes me up.
This would be super easy to filter out of the live stream feed. If the camera hardware knows when it switches between day and night mode, the camera could just mute the microphone during the instant when the filter clicks. Alternatively, you could filter the sound out of the audio in the App. In future versions of the camera hardware you could use a silent IR cut filter.
