Now that you can detect zombies, it’s also a good idea to monitor their movements. But don’t risk joining the undead ranks by following them around! Watch them safely from inside your base, and you’ll keep your brain intact. This chapter shows you how to make a surveillance camera setup with USB and wireless webcams, using a Raspberry Pi single-board computer to minimize your energy usage (see Figure 5-1).

Both projects in this chapter require you to download software, so you’d be well advised to think ahead and get your system set up before disaster strikes.
