Electrical connections. When planning where to put your indoor camera (sitting on a piece of furniture, mounted on a wall, etc.), make sure a power supply is located close by. 3. Outside For an outdoor camera, you’ll need an outside power supply or incoming cables through the wall. You can also use a light fixture for installing your camera.
