Using an infrared security camera behind or through a glass window at night can be challenging due to window glare caused by infrared LEDs, ambient lights, or status lights. Window glare or glass reflection can cause images to be washed out due to overexposure of lights at night, making it difficult to discern details.
On the other hand, cameras typically work well during the daytime. However, another issue is related to motion detection and motion-triggered recording when a security camera is placed behind a glass window. Motion detection may not work effectively through glass.
