Little Brother (Marcus looks for surveillance cameras)

I went into the bathroom and took off the toilet paper roll and replaced it with a fresh one. Luckily, it was almost empty already. I unrolled the rest of the paper and dug through my parts box until I found a little plastic envelope full of ultrabright white LEDs I’d scavenged out of a dead bike lamp. I punched their leads through the cardboard tube carefully, using a pin to make the holes, then got out some wire and connected them all in series with little metal clips. I twisted the wires into the leads for a nine-volt battery and connected the battery. Now I had a tube ringed with ultrabright, directional LEDs, and I could hold it up to my eye and look through it.

I’d built one of these last year as a science fair project and had been thrown out of the fair once I showed that there were hidden cameras in half the classrooms at Chavez High. Pinhead video cameras cost less than a good restaurant dinner these days, so they’re showing up everywhere. Sneaky store clerks put them in changing rooms or tanning salons and get pervy with the hidden footage they get from their customers—sometimes they just put it on the net. Knowing how to turn a toilet paper roll and three bucks’ worth of parts into a camera-detector is just good sense.

This is the simplest way to catch a spy-cam. They have tiny lenses, but they reflect light like the dickens. It works best in a dim room: stare through the tube and slowly scan all the walls and other places someone might have put a camera until you see the glint of a reflection. If the reflection stays still as you move around, that’s a lens.

There wasn’t a camera in my room—not one I could detect, anyway. There might have been audio bugs, of course. Or better cameras. Or nothing at all. Can you blame me for feeling paranoid?
