THE BUYING GUIDE
Active deterrence combines selected detection functions with a supported response such as light or audio on particular products. Choose the target event and decide where an alert is appropriate, then check the exact camera functions, schedules and recorder integration. These features should support a considered site response rather than replace it.
List the target areas, approximate viewing distances, daytime and night lighting, cable routes and retention needs. This makes it easier to compare cameras on useful evidence rather than headline megapixels.
