Guidelines for indoor security placement

Corners are your friends. Hanging an indoor camera in the corner of a room usually gives you the largest possible vantage point.
Windows can cause reflection issues. Pointing a camera out the window might degrade its image quality. Many security cameras have infrared (IR) light technology, which aids in motion detection and enables the cameras to function in low light. IR light can reflect off of windows and other glass objects and obscure your footage, especially in the dark. If your footage looks washed out or whited out, there is likely a reflection problem going on.
If it’s necessary to point a camera out the window, positioning the lens as close as possible to the glass and/or backlighting the outdoor area (perhaps with motion detector lights) are two glare-minimizing measures to try. It can also be helpful if your camera has wide dynamic range (WDR) technology.
Angle for indirect light. Again, direct light will wash out your footage. With indoor cameras, be mindful of lamps, light fixtures and bright windows. Avoid facing your camera directly toward any of these light sources.
