When infrared security cameras are placed behind glass, it can cause infrared reflection, resulting in inferior picture quality.
The best practice is to NEVER place your infrared security camera systems behind any glass. Instead, opt for outdoor IR surveillance cameras that are designed to withstand the outdoor elements.
Moreover, avoid mounting wireless infrared security cameras too close to a wall, ceiling, or in between two walls, as it can obstruct the camera’s IR LEDs and cause infrared reflection issues.
