After reading some of the literature on how the camera detects motion via temperature changes, I have realized a limitation of these devices. At first, I was happy with how the cameras were picking up on motion detection and recording events on our driveway. But as the extreme heat wave set in, the event logs became few and far between. My assumption is that the concrete driveways and street heat up, and therefore there isn't much of a change in temperature in the viewing range when people walk into the area. Knowing full well that someone is/was in the area of either of our cameras, there is still no event log (even with cool down set to 15 seconds and sensitivity at its maximum). Once known "events" occur in the cool morning, they rarely are missed. Our cameras are both mounted under the eaves on the east side of our house, so direct sunlight is not an issue. Overall, I am not impressed with the wyze outdoor cameras monitoring capabilities.
