While early camera traps were primitive and clunky, thanks to advances in technology and increased demand, they've now become significant and cost-effective research tools. As this video shows, they can be extremely useful to researchers and conservationists.

It's important to know, however, that they still have limitations. Humidity can cause malfunctions that aren't immediately detectable, so large portions of research can be lost without realizing until it's too late. It's also important to choose equipment according to what you're tracking.

Insects, amphibians and reptiles don't always trigger infrared sensors, so special triggers are needed. For most medium-large land animals, though, camera traps are invaluable surveillance tools.
