Fake security cameras are advertised as a cheap way to deter anyone who might be up to no good. This isn’t a crime and punishment blog, so we’re not really in a position to say how accurate that claim actually is, but we see enough of these things for sale that somebody out there must believe they’re worth having. Though if it were us, we’d take this tip from [Daniel Andrade] and convert our “fake” camera into a real one with the Raspberry Pi and WebRTC.
There are an untold number of makes and models of these fake cameras out there, but it seems that many of them share a fairly common design in that the enclosure they use is actually pretty useful for putting your own hardware in. They’re hollow, relatively well protected from the elements, and as most of them use a blinking LED or some other feature to make them look more authentic, they already have a functional battery compartment.
As it turns out, the one that [Daniel] picked up for $9 USD is pretty much perfect for the Raspberry Pi Zero and its camera module. He even wired the blinking LED up to the Pi’s GPIO pins so it will still look the part, though replacing it with an RGB LED and appropriate scripts to drive it would be a nice way to get some visual feedback on what the system is doing.
The software side of things is done with Balena, a suite of tools for setting up and managing Linux Internet of Things devices. They provide everything from the SD card image that runs on the Pi itself to the cloud infrastructure that pulls all the data together. [Daniel] dove a little deeper into the software stack when he created his Bitcoin traffic light last year.
For any readers who may feel a sense of déjà vu looking at this project, you aren’t going crazy. We recently saw a similar project that used an ESP8266 and a PIR sensor to add motion sensing capabilities to one of these fake cameras. Now all we need is somebody to put an Arduino in one of them, and we’ll have the Holy Trinity represented.
