Best baby monitor for night vision

I’m looking for a baby monitor (blue tooth - don’t want to use WiFi) with good night vision.

With my first, we had a Summer Infant one but eventually it wouldn’t hold a charge (after a year) AND it wouldn’t stay plugged into the monitor. The night vision was pretty good and range was excellent but didn’t have a sleep mode, which I prefer to have.

Then we got the Infant Optics after rave reviews. I like everything about it except the range (not far enough - we have a lake house and I like to sit outside during nap time so needs to reach pretty far) and the night vision is terrible (see photos)! I’m not sure how it has received so many good reviews. It works fine for my now 3 year old but I can’t use this for an infant.

Suggestions, please!
