Infrared security cameras have a tendency to wash out the picture when placed behind a glass window or panels at night or in low light conditions, making it challenging to see things clearly.
Some potential fixes include turning off or disabling IR and status lights at night to mitigate IR security camera window reflection and enable clear viewing through glass or glass window screen.
Additionally, you can bring the camera lens as close as possible to the glass to reduce window glare and reflection. Another option is to use a suction cup mount that attaches to the window facing outside or an external motion-activated or automated light outside that illuminates the front door or backyard, enabling security cameras to capture more details.
