Hey @anakin! It sounds like the lens might be adjusting to a bright environment while recording the event. When a Motion is triggered, it will activate the device to begin recording as soon as possible. Depending on the environment, there are times where the lens might be adjusting while recording. If there are bright lights or the sun is shining directly on your Cams, try angling them differently to avoid direct exposure.
Wifi signal strength, or RSSI, is always worth checking to ensure for the most optimal connection. While this doesn’t help with brightness, it certainly will help with how quickly the Camera can communicate an event and record video. It may even help with lens adjustment if you feel there is any lag in the beginning seconds of the video. Feel free to check back here for any suggestions from other neighbors in the Community!
