Now, (latest FW) when motion detection is ON and screen saver enabled the screen is turned on every time even when slightest motion is detected, which makes the camera very conspicuous and easily noticeable, especially at night.
The effect is the worst when there is only so much motion to turn the screen on but not enough to initiate recording. In that case the screen stays enabled forever. This seems to me as definite BUG.
After your question I’ve tried the factory reset and the result is the same. I’ve both A119 and A199s, but I’ve realized that on A119S M.D. doesn’t work at all. When the recording stops because of no motion, the image brightness falters which is detected as a motion and recording starts again. It’s a question if this is a SW or HW bug. It seams to me rather like a HW bug when a voltage falters when a power consumption changes.
This will be fixed in next firmware.
