My news feed is set to deliver news about the Raspberry Pi, Tasker, home automation, smart security systems and several more relevant information that inspire me and provide me with the knowledge for further tutorials.

In the recent weeks, I came across several guides/tutorials on how to use home automation to increase the security in your house.  With all the gadgets, sensors and IoT devices you might be tempted to wire up your house to create an elaborate and interactive home security system on the cheap. I’m not surprised that these methods are popular, as provide us with a cheaper alternative than a professionally fitted alarm system. It’s all great, but all these systems have one thing in common. The same weakest link. Learn about the biggest pitfall of the smart security systems

The biggest pitfall of a smart security systems

Turns out, that hacking into home automation systems is not needed. It’s time consuming and it costs money. Entire home-made security systems can be disabled with a free device in less than a fraction of the second.

The weakest link in your home automation is the lack of the separate power system, independent from mains. Unlike professional installation, you are very unlikely to put extra wires to power an IP cam, or a Pi Server. The router is probably also powered from the mains, same rule applies to security sensors.

Short the wires and you have the secret weapon.

Imagine the thief would short your mains socket. The fuse box will pop the safety fuse out, and anything connected to mains will get powered down. If you are lucky enough, it will power down just a single floor, leaving other devices powered on.

The worse case scenario is when you have an outside plug wired with mains running inside your house. Unless that socket comes with additional fuse installed, capable of blowing before the main one, everything will get powered down. This means no IP cameras, no servers, no sensors, no router to send you a notification.

Your entire effort could go up with the smoke. All that possible without stepping a foot inside your property.

How to prevent it?

This is a tricky question. Apart from having a completely separate circuit for the entire security system, you would need an UPS to keep the system online. This means some serious money. Creating a homemade security system requires you to always look at the weakest link. Don’t let it be the power supply.
