Put to­gether a smart se­cu­rity sys­tem

There’s no need to be alarmed. Or per­haps there is, if you care about your kit. For­tu­nately, it’s eas­ier than ever to put to­gether your own se­cu­rity sys­tem

When i bought my house, it came with an alarm sys­tem, but not an alarm code. So be­yond one ac­ci­den­tal ac­ti­va­tion that caused all man­ner of trou­ble, it and its net­work of mo­tion sen­sors has laid dor­mant for the past seven years. I don’t think it would like my cat col­lec­tion, any­way.

Don’t get any ideas, though. I’ve tooled my­self up with my own smart alarm, made from enough bits and bobs from my years of elec­tron­ics hoard­ing to trip, al­most lit­er­ally, at the drop of a hat. But not a cat. Cam­eras, sen­sors, the whole she­bang.

Ide­ally I’d like it to be tied to­gether in one app rather than three, but that’s a com­mon com­plaint, and some­thing that’s get­ting bet­ter as more de­vices sup­port pro­to­cols like Zig­bee and Ap­ple’s HomeKit. That’s rarely retroac­tive, but it’s an ex­cuse to up­grade, right?
