Doorbell randomly dropping frame and bitrate

[user_600965065629823_600965065629823]

I had set my Doorbell POE Clear Stream to 20 FPS & 6144 Kbps Bitrate and twice now it has dropped them down to 15 FPS & 1024 Kbps without me making any changes. The first time it happened was a month or longer ago (not sure how long it was until I noticed) and it stayed at the higher settings for over a month once I changed them back. Then at around 10am this morning it changed again. No firmware updates or manual reboots between it changing. Anyone else experienced this issue and have a solution?
