Have you ever wondered what this kind of ‘cheap’ temperature sensor is worth?

Anran AR-24NW-100-IP ONVIF with Synology Surveillance Station

3 hours trying different settings while I was right from the beginning! My mistake was not to wait enough after saving settings…

ESP8266 5V…12V voltage regulator

I’ve just received my ESP8266 expansion IO board but the pcb didn’t embed the 3.3V regulator (as expected according to the pictures from the eBay seller) 😦

As I have plenty of 5V, 9V and 12V salvaged power supplies laying around (and not a single 3.3V), I was very interested to use them with my ESP8266 ESP-07 module…

It was not a big deal to find out the needed regulator (with compatible pinout) but, as Google was not my friend this time, the operation deserves a few lines of blogging with IC reference… 🙂

Sricam with Synology Surveillance Station

I’ve just received my Sricam AP001 camera and while I’m very happy with the embedded web server and the Android application, it took me a while to make it working with Synology Surveillance Station (version 6.3).

ETS 5 tips

Here are a few tips I noticed while discovering ETS.

KNX MDT Glass Push Buttons

When looking for KNX switches for my house (under renovation) I spent a lot of time looking for THE right one.

Even if this one is not expensive (compared to other models on the market), KNX switches are not as cheaper as traditional switches and I couldn’t afford to buy all of them for testing before fitting the whole house :-).

I wanted something flexible and reliable with a great look and feel!
I read a lot and this one kept my attention, here is a small insight!

How I recovered my parents’ house alarm installer code or “security is not always where you would expect…”

I’m not sure I can ‘disclose’ the alarm system manufacturer’s name but they sell their products all over the world (according to their website), by the way I can see them everywhere I go 🙂

A few months ago I decided to open the burglar alarm control panel at my parents’ house.

I then see that, once again, security is not where I would expect 🙂
