In this week’s links post we mentioned an over-powered DSLR peephole that purportedly cost $4000. So when we saw this tip regarding a relatively inexpensive digital peephole, we thought some of you might be a bit more interested.
The hardware is quite simple; a decent webcam, a Raspberry Pi, and a powered USB hub. The camera gets stripped down to its PCB and hidden inside the door itself. Even if you see this from the inside it’s just a suspicious-looking wire which wouldn’t make most people think a camera was in use.
On the software side of things, [Alex] set up his Raspberry Pi as a 24/7 webcam server to stream the video online. Unlike using a cheap CCTV camera, his video signals are secure. He then runs Motion, a free software motion detector to allow the camera to trigger events when someone comes sneaking by. It can be setup to send you a text, call you, play an alarm, take a picture, record a video… the list goes on. His blog has a full DIY guide if you want to replicate this system. We just hope you have a stronger door!
We covered a similar project back in 2011, but it had made use of real server instead of an inexpensive Raspberry Pi.
[Thanks Alex!]
