13. A Built-In Security Camera and Emergency System Intercom
Video intercom systems are always found in every modern Japanese apartment. Besides, you will also see a picture of them on a tiny video screen instead of just hearing a person's voice through the intercom. The device automatically records the video footage onto an SD card if you are not home to respond to the visitor. This feature help adds protection to your home as you might not be able to identify them as a delivery person or a robber standing outside. Of course, other countries have similar surveillance systems with video intercoms. However, they could be quite pricy.
