Have been using a 5 Camera XT2 system for about 6 weeks now. One of the cameras now seems to have developed a fault. Previously at night this camera had the IR setting as Auto/low and provided a pretty clear picture at night. For some reason now the picture is too dark and virtually nothing can be seen. Tried changing setting to On/high, this seems to very slightly improve the picture, but nothing like what it was. It almost as if the IR emitter is either not on or very dim.
Any thoughts on ways to fix this? Picture shows camera with settings for IR at on/high. Don’t have a picture of the previous result, but the whole area here could be seen clearly.
