It turns out that I had the camera in a position where the infrared light was reflecting off the soffit (as in the first image below). I found this out after watching this video here: https://www.youtube.com/watch?v=Z97S7pytu-o. The solution was to move the camera forwards toward the fascia (as in the second image below). I also 3D printed a bracket that moved the camera down off the soffit by 30mm. The last image shows the improved quality of the video after moving the camera. The camera now catches events as expected.

@joseph_1979 Thanks for your help in sorting out my issue.

@joseph_1979 I increased the sensitivity to maximum, but the camera still doesn't detect events on the outside of the fence. I found that the camera will capture events on the inside of the fence, as in the image below.

@joseph_1979 Hi Joseph, thanks for your response. I had a look at the links you posted, unfortunately they don't have a solution for me, as Smart Person Detection on my RLC-1224A is working fine, during the day that is.

Here are some screenshots from both cams. As mentioned above, the RLC-1224A doesn't capture any events at night, so obviously there's no nighttime image for that cam.

I have a Duo 2 and a RLC-1224A connected to a RLN8-410. The Duo 2 captures events during the day and night, but the RLC-1224A only captures events during the day and fails to capture any events at night. I'd like to know how I can get the RLC-1224A to capture events at night.

Both cameras have the following settings:
