![]() ![]() The rear camera continued to record darker video than the front camera. The test setup was modified to have the front and rear dash cameras on the same window in my car (front windshield) to make sure both cameras were run with the same lighting conditions. The expectation was that the front video should be slightly darker than the rear video since the DR750X-2CH Plus front camera captured video at 60 fps vs the 30 fps for the rear camera with the same image sensor when both are exposed to similar lighting conditions. In the DR750X-2CH Plus case, the same image sensor is used in the front and rear cameras (Sony STARVIS IMX327). The rear video from the DR750X-2CH Plus dash cam was darker than the front camera in a variety of lighting situations. Pittasoft sent me a DR750X-2CH Plus dash cam to see if the same issue occurred with that dash cam. It's a firmware based decision on how to adjust the exposure level of the cameras for the lighting conditions. The X Plus series firmwares no longer allow the user to configure the camera exposure levels. I reported the issue to Pittasoft and after trying a couple different DR900X-2CH Plus cameras (front and rear) it appeared it was not a hardware issue. I noticed that the front and rear video from the DR900X-2CH Plus camera had different exposure levels causing the video from the rear camera to be much darker than the video from the front camera in similar lighting situations. A month or so after the review, I retrieved video files from the microSD card for comparison with video from another dash cam that I was reviewing. In September 2021, Pittasoft sent me a DR900X-2CH Plus dash cam to review.
