There are many suitable places you can install your Tempest device, e.g. on top of a fence, wall, railing, pergola, post, roof, chimney, etc. Here are some basic requirements: The Tempest device needs exposure to direct sunlight so its internal battery can recharge. Do not locate the device in a shady spot or it may eventually lose power. Choose a location that allows as much exposure to the wind, rain and sun as possible. Avoid close proximity to surfaces (buildings, walls, the ground) and unnatural moisture and heat sources (exhaust vents, central air units, active chimneys). The structure used to mount the device needs to be sturdy and should not shake, sway or vibrate in strong winds.
