Webcam turned security cam with motion detected email notifications

[Sean] used his old webcam to assemble a closed circuit television feed for his home. He already had a server up and running, so this was just a matter of connecting a camera and setting up the software. He wasn’t satisfied by only having a live feed, so he decided to add a few more features to the system.

He started off by hanging a webcam near the front of his house. He mentions that he’s not sure this will last long exposed to the elements, but we think it’d be dead simple to build an enclosure with a resealable container and a nice piece of acrylic as a windows. But we digress…

The camera connects via USB to the server living in the garage. [Sean's] setup uses Yawcam to create a live feed that can be access from the Internet. The software also includes motion detection capabilities. Since he wanted to have push notifications when there was action within the camera’s view he also set up Growl alert him via his iOS devices. You can see [Sean] demonstrate his completed CCTV system in the video below the fold.

Growling doorbell lets you know guests have arrived

wireless_doorbell_hack

[Sean] was screwing around online looking for nothing in particular when he came across a mailbox hacked to notify the homeowner when the mail had been delivered. Since his mail is delivered via a slot in the door, he had no use for the hack as is, but something similar soon came to mind.

His dog isn’t too keen on visitors, and he figured that he could save himself a bit of grief (and a lot of unnecessary barking) if he were to wire up his doorbell to notify him of guests via his iPhone. He stopped by the local hardware store and picked up a wireless doorbell. It was quickly disassembled and wired up to an Arduino he had set aside for a different project. Tweaking some code he found online, he soon had the doorbell talking with the Arduino and was ready to interface it with his iPhone. He decided that he wanted to deliver notifications to his phone via Growl and found a Perl script online that was close to what he needed. A few tweaks later, and he had a Growling doorbell.

As you can see in the video below, it works, though there seems to be a bit of a delay in the notification. We don’t think that it would be enough to send his visitors packing before he made it to the door, but the lag can likely be reduced with a few small modifications.

As for the post that started this whole thing, we’re pretty sure this is it.
