Security is one thing people care a lot, so every apartment building has got a Gate Telephone Entry. Visitors has to access their host via this remote access control system. But I always find myself embarrassing in front of a Gate Telephone Entry. For example, if I wanted to call my friend who live in 7th floor and his room number is 7, which number should I give? 0707? 707? or just 77? What's more, I'm not sure if I need to click '#' after inputing all the numbers. The instruction and interaction is not as useful as their manufacturres think. People have to call their host for help, which must be a very bad experience.
As the first impression, Gate Telephone Entry is way more important than people usually think. Especially for a company. With a worse Entry System, your customers will treat your company as unreliable. Even worse, because you only get one chance to make the first impression, it's hard to reverse their prejudice.
The same problem occurs on Digital Phone Entry or Access Control Device. Take care of these equipments and choose carefully before install.
