Way too many possibilities to give a definite answer.Obviously, it could be a wireless access point of some sort, although in that case I’d expect at least one antenna.Other possibilities:Motion sensor for a security systemHeat sensor for a fire detection systemTemperature/humidity sensor for the climate control systemReceiver for the remote control for the smartboard or ceiling-mounted projectorAn empty box that covers a hole where something used to be but is no moreAn empty box that was installed at great expense as part of a kickback scheme between the contractor and a school administratorOr, it could be a mind control device. Best leave it alone. You don’t want them finding out that you know.

It completely depends on the underlying construction of the home in which you are trying to do the installation. The simplest situation would be a home with a tiled drop ceiling in the living room (unlikely) or a drywall ceiling with space above it (more likely). The toughest would be an apartment in a building where the ceiling is a concrete slab.In the first case you simply use a ceiling mount for the projector and route the cords up through a hole in the ceiling,using either plenum-rated cables or a conduit across the top of the ceiling and down behind the wall, terminating in a junction box into which you would install a female HDMI connector.In the second case, your only options are either (a) use surface-mounted conduit across the ceiling and down the wall to a surface-mounted junction box,or (b) channel through the concrete, cutting enough out to allow you to bury a conduit in the slab, and then plaster back over it.However, there may be a better option, given recent advances in projection technology. If your ceiling has a ceiling fixture near where you plan to put the projector, I’d suggest simply running a power line from the fixture junction box to the top of the projector mount (above, below or in the ceiling, depending on its construction), and then using a wireless connection for sending video from the laptop to the projector. In 2018 you have a number of choices, including Miracast (the WiFi industry’s version of wireless HDMI), AirPlay (Apple’s powerful-but-proprietary solution), or a wireless HDMI video transmitter.Alternatively, if any of the above sounds complicated, and you have a bit of a budget, there are many local A/V installers who would be happy to take care of the whole problem for you, and quickly do a clean, invisible job regardless of the field situation.

They are quite practical, but a few things tend to make them less popular than large wall-mounts:Ceiling installation and the need to run power and input cables through walls and ceilings to keep it from being ugly.The need to have sufficient projection distance available.The cost of replacing projection lamps, which only last a few hundred hours. There are laser-illuminated models that solve that problem, but at a relatively significant additional cost.The additional cost of a suitable projection surface (better to use a dedicated screen rather than a “white wall.”)Less overall light output than a wall-mounted LCD even for high-end models, meaning ambient light control within the room is far more important than with an ordinary TV.
