I noticed from the 942L Firmware wishlist that the Day\Night threshold item had been addressed (via some sort of improved algorithm it seems). I hope that's an encouraging sign that we may see a resolution of that.
Another wishlist item: similar to the "disable motion detection during Day\Night changeover", it'd be nice to cut the audio feed during the instant of the Day\Night changeover as well. With the audio quality as it is, I frequently listen to the replay with the sound turned way up, but the clack of the IR filter is deafening.
