Where is POE installed?
The obvious disadvantage of these locations is maintenance access. For this reason, some POE applications have been installed outdoors either in a "box" mounted to the outside of the house, or curbside. This box must be heated and insulated and supplied with power. Outdoor installations, while offering much more convenient access for maintenance, are generally significantly more costly to install.
To reduce the risk of system tampering, some indoor-mounted POE systems have been installed in lockable enclosures.
