- no ESD (high voltage impulse) protection - reliable power source - compatibility with external centralized security systems protocols
I guess in every country any kind of monopoly leads to inflated prices and stagnation. We also have so many outdated and cost ineffective security systems here.
From the grid? See below. On the inputs? No, you're right.
> reliable power source
Not included in this post, because I'm not done with it yet, is the backup battery. The entire system runs on a 7.2Ah leaf-acid battery, which is connected to an electronic charger. So the alarm system power is isolated from the mains. I'm going to document this later in the series, when I'm all done :)
> compatibility with external centralized security systems protocols
I didn't really consider this, but it's easy to add if needed. Any examples?
