Review on Dorhea For Raspberry Pi 4 B 3 B+ Camera Module Automatic IR-Cut Switching Day/Night Vision Video Module Adjustable Focus 5MP OV5647 Sensor 1080P HD Webcam For Raspberry Pi 2/3 Model B Model A A+ by Romas Pennington

I have two of these cameras and both have the same basic problems: the IR-cutoff circuit does not activate properly in low light and the IR lights NEVER shut off in daylight. Although the IR lights have trimmer pots to adjust the switch-off threshold, the circuits are so out of balance that no amount of adjustment will get them to turn off in darkness and turn back on in daylight - they can only be rigged to either be on all the time or off all time. Also, one of the units came with a broken video connector. Pretty disappointing!
