The best place to install your Wi-Fi security camera depends on what type of mount it has and whether it's an indoor, outdoor, or indoor/outdoor camera. Many of the indoor cameras on this list can be put on a shelf or table in a corner of the room to be covered where nothing will block its view. And the main controlling factor on where they can be put is the length of the power cord they come with. However, putting them up higher gives them better coverage.
Wi-Fi Security cameras do best up high to give their signal the most range. Most security contractors will install wired and wireless cameras in the upper corners of rooms, both ends of hallways, and at the tops of stairwells to obtain the best coverage At least one camera should be installed in the garage
in such a way that opening either outer door doesn't cause the camera image to white out.
The farther away from "the action" a security camera is, the lower the quality of the intruder's image that it's going to capture. This drawback is enhanced when you're dealing with night vision, as most don't work past 15-20 feet. If you have a room that's longer than 10 feet, you should consider putting cameras at both ends of the room to overcome this deficiency and get the cleanest images possible when you really need them.
