There’s a DIY surveillance camera project outlined at Making of the Autonomous Surveillance Camera that aside from acutally working, can email you photos of the room it’s watching when you ask it to.

Here’s how it works:

It uses cellular network for communication. The device checks pre-defined email mailbox once an hour. If a new email is received the camera takes a picture, saves it on a SD-card and emails the image to its owner.

This produces still images on a time delay but, it can provide you a little peace of mind if you need to check on your home. You can build your very own camera with:

1. A modem
2. JPEG camera
3. SD memory card
4. Micro-controller and integrated circuit
