Bonus Tip: How to Set Up a Home Theater Automation

After a day's hard work, wouldn't it be a great relief to watch a movie at home on a big night? But it can be a bit confusing with all of the options available. It doesn’t have to be. With a few tips and planning, you could be enjoying your cinematic experience in your personal home movie theater.

Then by following the steps below, you can clearly choose your suitable smart home theater configuration. Creating a smart custom theater is all about finding the right “brain” to connect all the equipment. In this part, we’ll look at the steps of how to set up a home theater automation control system.

Step 1: Consolidate the controls

Usually, there is a separate remote control for a device, such as one for the stereo and one for the display. But when you're ready to start watching a movie, you need to find dozens of remotes for your devices and operate them one by one, and that can seem cumbersome. Then connecting all these separate physical controllers together through smart devices will make the movie watching experience much more convenient and better.

Step 2: Weighing price and quality

Generally speaking, the higher the price, the better the quality and experience will be, both in terms of life time and to the performance of the device, and if you are able to purchase the more advanced ones, then the device will interact with each other better. You wouldn't want to change devices too often, would you? Then when it comes to picking a device, you can consider both price and quality and choose the one that best meets your needs.

Step 3: Set the scenes

The scene setting step is very important to create the atmosphere of the movie, first of all, it can enhance the immersive experience of the movie. Secondly, it can provide moviegoers with a more private viewing space. For example, a “play movie” scene may connect a series of automated actions that should take place when a movie plays: lights dim, blinds lower, sound and projectors roll, and the film begins to play. On top of these settings, you can set up personalized light setting options ahead of time according to your personal preferences, and then wake up by voice before each movie, which adds convenience.

Step 4: Use multicontiguous screen device (MCSD)

Utilizing MCSD can make your viewing experience more continuous. For example, if you suddenly want to go to the restroom or someone knocks on the door in the middle of a movie, you can go to another room, and if there are smart screens connected to each other, you can continue to watch the video content on the restroom's screen or the doorway's screen. It is also possible to connect the security camera into this system as well, then you can monitor the whole home from the movie room.
