Last year, [Mark Simonelli’s] wife asked him if he could design something that would allow her to remotely check if their garage door had been left open. [Mark] jumped at the chance to tinker with electronics and designed a system around an old TrendNet IP camera. When remotely connected to the camera using IP Cam Viewer Pro for his Android phone, [Mark] could watch the video stream and also trigger the garage door opener via a small relay circuit he built.
His remote opener worked well, but his camera unfortunately lacked any sort of IR vision/low light capabilities. Since his camera wasn’t very useful in the dark, he decided that he needed to add some way to trigger a light when remotely monitoring his garage. He figured the best way to do this would be to control a power strip-connected light using a circuit similar to the one he built to open the garage door itself.
He stopped by the hardware store and picked up a cheap power strip, disassembling it and removing the power toggle once he got home. He fitted it with a small 5v relay, which he connected to the camera’s terminal block. While he admits that it might not be the absolute safest solution, he can easily control both the light and the garage door with a simple swipe of his phone’s screen.
